- This is a video to diagnose the causes of poor starting. I look at air in the fual line, glow plug testing and finally electrical problems with the starter motor. A number of faults were found including air in the fuel line and a starter motor drawing too much current. There is a second video here that shows how to replace the starter motor.
• Ford Mondeo Mk4 diesel...
Hi Nigel, my starter motor was playing up, after watching this brilliant informative video I cleaned my negative terminal and so far the starter motor problem has gone, keep up these great MK4 videos thanks and very much appreciated Kev xx
I hate to tell you but my problem was actually the starter motor failing. Check out my video of changing the starter motor and how I diagnosed it was at fault. Thanks for watching and the comment.
Owned a 2012 mondeo diesel for about 4 years. No issues so far except a new clutch 12 months ago. Decided recently to start completing its yearly service myself. Good videos. Certainly be a useful resource for information about my car!
My 2008 2.0 litre Mondeo refused to start after I had stopped outside a shop. It had been taking more cranking than it should have over a few previous weeks. Some sure start from the rac rescue man got it going eventually and you could see copious amounts of air in the diesel pipe going to the pump. My local garage found the hose coming from the tank was sucking air so they replaced it. The car is starting fine now and unless it's my imagination I think it even goes better. I also had the battery changed for good measure. Thank you for doing the video, i thoroughly enjoyed it as you were bang on with your method of diagnosis.
I had a similar problem with an old ford Capri I had. The starter would labour dragging too much power from the battery leaving little juice for the points ignition system. I changed the starter for a reconditioned one and problem solved. Nice informative video.
Thank you for this, it has helped me diagnose the starting issue i had with my Focus C Max as being down to an underperforming starter motor.
Thanks for making this video I didn’t have all the issues you did but I did have a dirty negative connection. The car now turns over much quicker
Hi there. Great vid. Very clear information. Really helpful. My only reservation is the dismissal of an injector issue. Poor starting can sometimes be down to the leak off element, inside the injector being faulty. Really common, on common rail engines. Especially that age. You could even have the issue so bad that it barely starts, but once started. They can show very little, to no symptoms at all. Eg normal MPG, engine performance and no smoking. I’ve changed literally 100’s of these injectors for this exact fault. But still, thank you very much for taking the time make this video. 👍
Hi James. Thanks for the comment. Sharing experience really helps us all. My problem turned out to be the starter motor. Incredibly it still turned over while drawing way too much current. I made a video of changing it.
Hi Nigel, congratulations for a very good & explained video !!!
A clever bloke, excellent troubleshooting 👏🏻
Your videos help me alot. Thanks for taking the time 👍
OMG, you are a legend. Thank you so much for uploading this, my Mondeo has just started doing the exact same thing and we were at a complete loss to why it was happening. Strangely enough, I also just had the car serviced end of August. The information you gave made it possible for me to go back to the company that serviced the car, and with the knowledge you gave me....I was able to get the car booked into today for them to look at the problem. Thank you so much.
Glad I could help. The fault was the starter motor failing. Check out my other video where I change the motor and do some voltage checks.
@@NigelEaland Hi, I am having issue the engine start and my mechanic says issue with the fuel injector and fuel pump. Its not still starting the engine.
@@tusharmalik4247 the mechanic is probably right. You need to check for the OBD error codes. See this video and the second one and Forscan.

excellant video, i have had similar with earth lead on gearbox mount....more the bolt not making a good earth through the gearbox mount into the gearbox casing
That's great advice thanks, was just about to change my glow plugs before I see this 👍
That was actually a great tutorial & guide. Thanks.
I began to have intermittent starting problems on my 2008 2.0TDCi Mondeo (152000 miles) last year but things got much worse a few weeks ago. I followed your reasoning and went through all the checks that you suggest and came to the conclusion the starter was at fault. New starter motor and the difference is unbelievable. The engine really turns over at speed now and starts first pop every time and has been that way for three weeks and dozens of starts. I really didn't notice how the old starter motor had deteriorated, as the decline in cranking speed is gradual and doesn't attract your attention until it finally gets too slow for the engine management's requrements to start as you mention. I'll strip the old starter to see what's deteriorated, but probably worn brushes/commutator and burned and high resistance solenoid contacts. Many thanks Nigel, saved me a lot of bother and expense.
I had the same surprise. You expect a motor to either work or not. To have one that still turned over but with high current draw is strange and through me off the scent for awhile. The final clue was measuring only 8v across the motor where there should be at least 11v.
Thanks for watching. Well done with the fix.
Great diagnosis and logical thought pattern.
Very informative video with great troubleshooting, thanks.
Thumbs up from me, lots of useful info and tips 👍 better than spending money on replacement parts
What?! Lol I can't believe that it all came down to that little nut. That's mental.
Thanks for the video. You're a great teacher. Very easy to listen to and you clearly know your stuff. Bubbles 👍🏽
kris Williams unfortunately it wasn’t the end. The excessive voltage drop was due to the starter motor drawing excessive current. I had to replace it. See my other video about the starter motor change.
@@NigelEaland starter motors on these tend to go bad after around 75k km
Really good video, thanks Nigel!
Fantastic video, well presented and clear. Thank you. Subscribed.
I'm having a similar problem with my mondeo mk4 petrol. It struggles to start not just in the morning tho. Great video very informative.
See my starter motor video. That was the problem.
Very good video . thanks . Small battery with low cca . Greatings From Norway
Really informative, thanks.
Thanks for the videos Nigel always useful and informative
Unbelievably helpful!! I've had real slow cranking of the engine and thought that there was something draining the battery. I got the local garage to replace the battery in spite of their protestations that there was nothing wrong with the starting. It still never turned over like a normal engine and has got gradually slower with the lower temperatures outside. Now, it's hit around zero degrees outside and the engine barely turns over and doesn't start. Battery out and charging overnight. I'll go and clean up that negative earth on the body and hopefully that helps! Many thanks.
My problem in the end was actually the starter motor failing. It appears to be a common problem. Check out my video. Thanks for watching.
@@NigelEaland I've got mine booked in for next week and a starter replacement too - common fault at this kind of age, no doubt! Thanks again - you should have been a Top Gear presenter instead of those three idiots who ruined it! Long live William Woollard!
@@bandagefreak thanks for that. That just made my day 😊.
Connections being poor will break your motor down. High currents melt the windings
Thank you Nigel, I might have the same problem with my 2006 c-max TDCI .
Me too!

Really good video thankyou
This kind of car diagnostics performed by "hands on", experience, knowledge and human resonation is by far lost in newer generations of mechanics nowadays. So many car mechanics only look at what "the computer says"🙄 Resulting in expensive and unnecessary changing of parts in many cases.
You are quite right. When I did this the garage had guessed it was the starter motor but was not sure. I’m an engineer, I don’t guess I diagnose. I found a number of minor issues but eventually by taking voltage measurements I proved it was the starter motor drawing far too much current. Thanks for watching and the comment.
Thanks Nigel. Very interesting about that earth connection. On my boat I cannot use the steel hull for neg. return due to potential hull corrosion problems so all earths go back to battery by insulated cable. I smeared contact lube on each connection to avoid any corrosion problems. Seems to work well.

Brilliant, thank you👍🏻
Thanks for this useful information. I'm going to check out the earth clamps now. My 2.2 diesel mk4 has a starting problem. Most recently with not a bit of sound at the starter motor . I took the starter off and bench tested it and motor and solenoid seems to work fine. looked at starter fuse - ok , looked at starter relay - it showed main contact continuity when powered up. Checked solenoid cable where it connects to the starter and when the key is turned the starter relay clicks but no power detected at the solenoid using multimeter or test bulb. I have earth continuity between battery and engine casing but not sure how much resistance yet.
If I read this right it sounds like the + 12v cable from the battery to the starter is open circuit.
The earth connection problem is common on ALL Fords from this era and terminal design. Fiesta Focus Mondeo. Pull the battery box and air cleaner, this will give you access to the earth points on the chassis rail and gear box, there are big fat wires and smaller wires. my mk2 focus had at least 3 or 4 in this area. Unbolt and clean EVERY connection then reattach and cover in corrosion inhibitor of choice( grease, petroleum jelly etc) I also ADD another aux cable from the frame rail back under the air box back to the earth point on the strut tower next to the battery to make a better earth path. You will be amazed at what other electrical issues will now disappear .
Unfortunately the earth lug on the chassis was not the problem. The starter motor was failing and drawing far too much current and that is why that connection was getting warm. Have a look at my starter motor change video where this story finishes. Thanks for the comment though as I’ve read that mk3 Mondeos sometimes had an earthing problem.
Nigel, I had similar problems and cleaned up all the connections. What also helps is a BMS reset! You will find that all the electronics and sensors will work much better after that.
Thanks for watching. The problem was the starter motor failing by drawing far too much current. Check out my starter motor video.

BY THE WAY,few months ago,my ford mondeo not started anymore-WHAT I FINDED?? INCREDIBLE!!-one small tube which is for break vid pump and use this vid also for cold schock ,was cracked,and for this you can start anymore,all this for vibration and poor tube plastic quality
Very good video mister ✌✌✌👌
Superb video!
Thanks and thanks for watching.
Foe once a youtuber that knows a car. I realy like this video
Thanks, I appreciate your comment.
POOR STARTING SOLVED - I have finally resolved the starting issue on my Mondeo. Doing some late night research on the Internet I found a web page that described the voltage drops you could expect on the starter motor circuit. The starter motor should see about 11v on cranking and the drop from the battery to the starter motor on both the negative and positive sides should be less than 0.4v. The voltage drops I measured are way to high and is a sign the starter motor is drawing far too much current. Armed with this information I've changed my starter motor and the car now starts perfectly. My video to replacing the starter motor can be found at th-cam.com/video/16rgA_bs0LU/w-d-xo.html
Any associated clutch /flywheel issues, metal filings etc?
And this Duratorq engine under Siemens control require at least 200 rpm before ecu will feed the fuel. Same trouble all eyes looking on tired 12 years old starter.
theflyingmilkfloat I checked for dust once I had removed the starter motor. Thankfully the starter ring was clear. I had a mk3 once and that had a MDF failure just as you suggest so I was looking for it.
Very good info nige l keep it up I don't do garages only for test been at it since 17 yr old now 72 keep at it just done honda crv clutch on the drive 2 and bit days but done it honda wanted 2000 pound cost 330 valeo mk3 job done happy days
Top work Alan. I have the same story. Started pulling motorbikes apart with my dad at 16 yr old, I’m now 63. I have saved a bucket of money by doing my own service repairs over the years. My own comment about the CRV clutch is you should have filmed it for me to watch on TH-cam.
Good video cheers
Thank you
Very good 👌
I've now subbed to You Nigel! And Great Work on the Project CD345 Too! Keep up the good work AsF too!😎👊🏿🤜🏿🤛🏿👍🏿
Just a general comment, based on years playing with boats. Funny when you said issues with slow starting...my instant thought was the negative side. I would add an actual heavy negative lead to one of the starter motor bolts to bypass the puny ground system.
Wow, i dislike the idea of a ground so much. Every high draw system should always have both positive and negative leads running directly to it.
I agree as I also play a lot with boats. I believe the mk3 Mondeo had a known weakness with poor connection to the chassis. The issue was my starter motor drawing far two much current. I had voltage drops across every connection. The eventual solution once I had worked out what was going on was to change the motor.
Thanks for watching and the comment.
Just both one, same 2008 2.0tdci, and I notice the same problem in the morning, I will try your advice, Thanks.
Particularly measure the voltages to the starter motor. My problem was the motor taking too much current. See my other video.
There must be also connecting wire for ground between body and the gearbox, that also can be dirty.
Hi!Good video!Unfortunately proper glow plugs resistance doesn't mean that glow plugs work correctly!
That's true! The glow plugs should heat the most at their tip; a worn-out glow plug might heat only the middle section, thus not being effective at all, even though the resistance looks to be ok! Thanks for the video!
I Have 2010 Mondeo 1,8Tdci 400K km Still original turbo,injectors,pump...No Dpf. Only Egr removed and chiped. The Belt Change are expensive every 200K km :) Use Valvoline Synpower Fe5w-30 very 10-15k km. ENgine is very clean inside
Exact same problem, exact same engine.. but on a 2009 S-Max... I hope it's the same easy fix
Update on the Mondeo. I've had the starter motor out and there is no debris from the clutch in it, so that's good. Most of the starting issues have gone away except for the first start in the morning. At the end of the video I said I was going to check the other connections to the starter motor to see where volts are lost.
My battery has 12.6v across the terminals before start, on cracking it drops to 9.6v. I have further losses on the red positive cable to the starter motor of 0.8v. The battery negative terminal to chasis connection losses 0.4v and the chasis to engine connection losses a further 0.4v. All these losses are due to high current and a small amount of connection and cable resistance. If you do the maths the losses amount to 1.6v and hence 8v appears across the starter motor on start.
I'd be grateful if someone can post similar readings from a good Mondeo to compare.
One last thing. I've found that turning the ignition on for 5 seconds, five times and then go for a start it fires up first time in the morning.
Any updates on the mondeo Nigel?
Have you had a battery load test done. A battery can have a bad cell and still read 12.6v but have reduced current flow... Most batterys only last 5 years. What i find the most common cause for this problem is just a week battery
@@whothe_f7057 I have a galaxy 2.0 tdci which is rough on cold mornings and my lights flicker every morning for a 5-10 mins. After that it turns over 1st time smoothly with no flickering unless its left standing for 6 + hours. I've had alternator and battery tested and all is well but could the battery still be faulty as your stating
I had the same problem on my transit van so I changed the ignition switch problem solved £5 on eBay easy fix
From an old RAC Patrol, look up Voltage drop test.
The old PSA DW10. PITA to work on!
Thank you very much for this Nigel, this is very informative! I am currently trying prime the fuel line and I noticed that there was one comment you made in this video at 5:28 that the valve that is on the fuel line should not be opened, but I have heard from others that you can get the air out much easier by using that valve.. Can anyone confirm that this valve can be used to get air out of the fuel lines?
Hi Kristjian. Have look at my video for changing the fuel filter. I show how I bleed the line.
Hi Nigel. Just bought a 2008 2 litre diesel. Had problems with it turning over. Took three or four seconds. Battery was nackered. It was the original battery from 2008. That's replaced. Turns over straight away now.
However, when it turns over is is extremely choppy for about five minutes. It turns an stutters and almost seems like it will konk out. I have to keep the key turned and hold it when starting to ensure it turns.
Anyway once it's running it's just very choppy and noisy got a few minutes. The only way I can describe it is like an irregular heart beat. It's ticking along but every few seconds the engine kind of jumps and it stutters. The engine is also quite loud if I drive it like this for the first five minutes.
Now after five minutes it's fine. If I take it on motorway it drives like a dream so it's not fuel starvation like you said.
It's just very annoying. Only seems to be issue when it's cold and started. My mechanic had a quick look. No engine light or code.
I don't want what to do. I want to get it sorted it's definitely not running correctly when cold. What do you think?
It seems to me there are three possibilities. Glow plugs, air in the fuel line or a poor injector. The first two are easy to check as shown in the video.
Given that it is quite cold at the moment I would suspect glow plugs or the relay that feeds them.
Checking injectors is more complicated. Search you tube for inject leak off test.
@@NigelEaland Top man thank you very much. Will keep you updated
@@NigelEaland hows it going. Glow plugs and fuel line are ok. Looks like it may be injector. Is that test you mentioned the only thing that can be done to test them without stripping the engine? Also what type of money are you talking to replace one once its identified. I have located a good few second hand ones as new ones are mad money. how much would the labor be ball park?
12332pj the leak off test is the only way to test the injectors while in the car.
Replacing the injectors is straight forward enough but does require a special extractor tool and requires the the ECU programmed with codes that match the new injectors.

Hello, I have the same problem, did you solve it??
Hi Nigel wondering if you can help I’ve had a new clutch and fly wheel put in my mondeo mk4 1 month ago today it made a funny noise on starting so you think it’s the clutch or starter motor thanks
good man take it back to where you had the clutch done and ask them to check it.
Hi Nigel, I have the same problem on my car " Ford Mondeo Mk4 2.0 TDCI" It has air into that pipe that you showed in the video.
About 1 month ago the car start loosing power and I couldn't increase the revs above 2500.
At this point I suspected that I should do the service and in the next week I've done it, but this did not fix the problem.
Next step I found a error code P0088 "Fuel pressure regulator" and I've decided to replace the sensor.
I've been to a garage to replace that sensor, the guys from there...replace it, but when they took the sensor off from it place, the engine or pump loose the pressure.. they've been trying for about 5 hours to start the engine "engine Cranks but won't start ".
I don't really know if the air bubbles from that pipe have been there before this or not...but what I know is, that the engine was starting easily before changing that sensor.
Now the engine Cranks but not starting at all.
Looks to be the same problem like your car "air bubbles ", but the difference between is that your car is starting and mine not.
Can you please help me with some advices ?
Thanks in advance.
The air in the fuel line will definitely stop the car from starting. You need to find where the air is getting in. Feel the joints as I did to see if diesel is leaking working your way back from the fuel pump. If they are dry go under the car and check the filter drain valve and the housing are tight and there is no evidence of diesel dripping. Finally attempt to prime the fuel line as I showed with the hand pump. Once there is only a little air in the system it should start and clear itself.
@@NigelEaland i suspected that maybe from that sensor something is wrong, maybe it is not on it's place.
What do you think about that ?
Or maybe the high pressure pump ?
And i have one more question for you.
This type of car has a fuel pump inside the tank ? And probably is not pumping enough fuel to the line ?
Yesterday i tried for hours to prime the fuel but i still couldn't do something with that bubbles from that transparent pipe...
And when i prime fuel i take out of the system lots of big bubbles and it didn't stop in all this time.
Thanks for help again.
Pintilei Alexandru there is no pump in or near the fuel tank. The engine fuel pump sucks the fuel but it can’t do it If there is air in the low pressure line. If you have air then you see a small amount of diesel where it is leaking. It could be that air was introduced when the sensor was changed and that the line has not been primed properly. To move forward you first need to get that air out of the line.
@@NigelEaland When i go back to the car, I will take that sensor off and i will check if everything is in place.
The guys from garage ...they took off even the high pressure pump...so there could be a problem aswell...with this air in the system ?
Definitely first time i will try to get the air off from the line.
Thanks.
Hello nigel any addive on how i can run wires through the fire wall of my mondeo mk4
Follow the cabin loom that goes through behind the fuse box in the engine compartment and appears behind the glove box on the passenger side.
Really worthwhile video thankyou. Nigel do you have a post showing how to replace the glowplugs on this vehicle. I believe you have to remove the EGR cooler/valve?
Sorry I don’t have a video. It’s not going to be easy as they are behind the engine. Did you test them and the voltage from the relay as I did in this video? If they read right I wouldn’t try getting them out.
Ill try that first then thankyou
hello,now i modified again,so,i installed original filter,but i checked if not loose any air,vaccum test,and i installed special transparent gasoil tube for in and out diesel filter,now i have 2 months and no buble air all time,so all is perfect,perfect start also after 1 week,cold ,etc,so i hope i finished with problems-what i am very angry,i consulted ford partner from uk,germany and italy,all are dumb,no interes for fix this problem just money want-in fact from original tube ford i finded only one oring from plastic connector,possible jumped from his position,now i finded on aliexpress original connecter ,look fine,2 orings,hope good in time
Nice tips, but when you test the glow plugs ,where did you put the black end multimeter ?
On to the engine metalwork. The engine has a cable strap back to the negative of the battery.
That cap on the fuel line from the pump is not for releasing air; is a valve for measuring the pressure. Under the cap is a valve similar like those on the wheels.
Really? That valve is on the low pressure side before the fuel pump so I don’t follow what pressure would be measured. I’m not clear what the valve is for. I assumed it was for a garage to fit a suction pump to bleed the lines. Either way I didn’t mess with it and bled my lines in a different way using a hand pump connected to the return pipe. Thanks for watching and for the comment.
Nigel Ealand
Yes, is on low side, but if the pump from the tank is not pumping properly from that point you can measure the pressure.
Is a Schrader valve. In theory should be also on high side.
For example on my mk1 petrol mondeo I have it also, and helped me once to diagnose the non return valve from the fuel pump.
Anyway, you did a great job.
Thank you for sharing.
SuperMadcox and thanks for the update.
@Nigel Ealand Thank you for this video. I am currently investigating my mondeo mk4 2.0 tdci starting issues. Just a question: When you say that the starter motor needs at least 8 volts, is it with engine off, key on or just at the starting moment?
I hope you understand my question :)
Hi Tommy. It’s at the starting moment when the engine is cranking over.

Hi, I got Ford mondeo Estate 2 litre 2009, diesel. It started to blow white smoke every time I start it. What could the issue be.
White smoke is unburnt diesel if it’s not steam from water burn off in the exhaust. What does it smell and feel like? Look at injector issues.
Great video .i will check that connection .thank you .👍
Alternately it was my starter motor. Have a look at my other video. Thanks for watching.
What is a location of boot fuse in mondeo 2010zetac 1.8 diesel
See this fuse-box.info/ford/ford-mondeo-mk4-2010-2014-fuses/amp
Was your issues every time you went to start or intermittent? I have an intermittent start issue where it takes a good 10-15s of cranking to get a start. Once started it chucks a bit of I burnt diesel smoke out and then runs perfectly
It was every time it was cold. I worked out the starter motor was drawing far too much current by measuring the voltage across the starter. It had only 8 volts, enough to turn the engine over for but not fast enough that it would start. I did a video of the starter motor diagnose and change. It’s quite a common problem on a Mondeo.
Ah ok. Mine will sometimes start first go on a cold damp morning. I’ll try all the suggestions you made in this excellent video and see what happens.
Hi Nigel, I’ve watched your video as it seems that I am having similar problems with my 2007 focus. However I’ve changed my Earth and the problem still proceeds. Could you help? Two garages have failed to solve the problem and I’m no car guru lol, thanks.
It’s hard to say as there can be many reasons why a car fails to start. The video shows how I made a process of examining, testing and eliminating various parts leaving just the suspicion that the starter motor was at fault by the voltage measurements I made. Have a look at my second video about replacing the starter motor. If you or the garage can measure the voltage across the starter motor and it reads less than say 11v then the starter motor is drawing far too much current. They are weak on the Mondeo. th-cam.com/video/16rgA_bs0LU/w-d-xo.html
Bad connections, current increases voltage drops.
Had same issue with my 2 2tdci
hopefully i find my earth/negative connection is loose. Cheers
Dave it’s not a bad connection. The issue was the starter motor winding was breaking down causing high current to flow which then results in small voltage drops across the connections.
Hi Nigel ever come across a problem with the high beams flickering on and off I can hear the clicking in the glove box
Hi Tom.
There is a relay/ fuse panel that sits under the glove box. You can move the carpet and drop it down. What you are hearing is the main beam relay chattering on and off. This is most likely to be a loose connection of the control wire from the high beam switch which makes or breaks with vibration as you drive along. Looking at the wiring diagram the main beam switch control goes to two places, the instrument panel blue light and the relay below the glove box.
Firstly you could drop the fuse box and make sure the relay is in place and waggle the cable loom to see if you can provoke the fault. Secondly if you drive along and you hear the relay clatter and the blue light on the instrument panel flickers then it’s a bad connection on the main beam switch. You might be able to get your hand on the cable loom on the steering and provoke the fault that way.
Good luck.
@@NigelEaland thanks Nigel I'm gonna have a look later and see if I can figure it out... appreciate the reply ..noticed the rear tail lights are flashing aswell now
this engine to work on looks very difficult, its completely different than the other common rail diesel just weird desgin
Hi, good video, can you tell me where the glow plug control module is located thanks
The relay I believe is under the battery shelf.
Hi. I have a Mondeo 2015, 2.0 diesel and when the cold weather comes, It is slow to start. It always conects, but It seams It does It in slow motion. Normally It start under 1 sec but in the cold It takes 2-3 and It sounds like It is struggling. Also when I engage aditional heating(webasto) and leave It for a couple of minutes to heat up It starts regulary in a sec. I changed the battery, I changed all 4 heaters and checked the started and everything is ok. What Could possibly be the issue? The car drives great, no problem whatsoever.
Go and have a look at my video about changing the starter motor.
My poor starting was the starter motor and I changed batteries before I realised what the problem was. When you say it does it in slow motion I assume you mean that the engine turns over slowly when cold. If that is the case then it points to either the starter motor or the battery or the connections between the two. If you can measure the voltage across the starter motor while the engine is turned over. You should see at least 10 volts. Do the same with the battery. If you see less than that and there is quite a difference between the two then you have a fault.
Yea I will give It a go, It does make sense. Someone told me that maybe It could be injector, that on cold weather It does not produce enough fuel in cilinder.. But I dont see any evidence for a bad injector, no smoke, no errors on computer, no problems while driving...
Hello. Did you resolve the problem with a cold start on your mondeo mk4?? I have the same problem😢. Best regards
When you see a Mondeo on ebay with 480,000 miles one can only assume their good cars.
They are good cars. That’s not to say they don’t have their faults as my videos show. Mine is a complete work horse. It has so much space in it to shift stuff and still give a comfortable ride. The fuel economy is good and they are reasonably priced. It’s a shame they’ve stopped making them.
@@NigelEaland Ford Mondeo's are certainly comfortable and roomy especially the hatch with a space saver wheel, been using high mileage diesel ones for twelve years, only problem letting tank run nearly empty too many times knackered the injectors, shell nitro seems to work wonders to preventing problems.
@@NigelEaland I believe if the steering wheel switches give a problem compressed air blown underneath can sometimes solve the problem.
I'm looking at buying one of these, is it worth it? I'm looking at a 2010 1.8 diesel. It's in great condition I'm just wondering will it be reliable?
I love my Mondeo, it’s a work horse. Yes it’s had a few problems, hence the videos, but over all I would say it is reliable. I’ve had it 7 years and things do break but are easily fixed. It’s very comfortable to drive, low running cost, tons of space inside and on a long run I get over 50mpg. Most important is to find out when the timing belt was last change.
Good video. Just curious how you came up with the 150 watts. how was this calculated. ohms law??
Basic laws are Voltage = current * resistance and Power = (voltage * voltage)/resistance. I had 11 v across the glow plugs and a resistance of 0.8. Power = (11*11)/0.8 = 151w. The current running through each = 11/0.8 = 13.75 amps. Thanks for watching the video.
@@NigelEaland
Thank you very much. much appreciated.All makes sense. Good to know this when diagnosing electrical problems
how did you measured the starter motor? on turning the key to start the engine, you measured from the lower bolt and the body?
That’s right. The bottom terminal and the motor body. You should see 11volts. If less than that and the battery is charged then the motor is drawing too much current. This was the problem with my poor starting. I replaced the starter motor. See th-cam.com/play/PL-KtFBm8pCXccYYGDwhyaufzQ2ZtX0Bm4.html
@@NigelEaland thanks! i have a ford focus mk2 2.0 tdci 100kw and i have problems with start up. my car in the morning or after i left it for more hours strats very hard. it turns for a couple of seconds (sometimes 10-15 seconds) before it starts. i've changed the glow plugs and checked for 12v, i've replaced the fuel filter and primed it so no bubbles in pipes; i've changed the battery to a new one; i've checked the alternator and it is charging. the last thing that i have to check tomorow is the starter motor. thanks!
@@ionutz12e mk2 Mondeo with original starter motor in it? It's toast, especially if it's got over 75k km on it
hi all,i finded also another issue from project!!!! mondeo 1.6 ecoboost 2011--poor start in the morning 0 degree--original diesel filter 150 euro new,with water sensor inside,introduce a lot of air,that s why i modified my onstallation,and i replaced original diesel filter with old mondeo diesel filter which have no more water sensor,just sample filter,i replaced also with transparent diesel tubes,for air bubles all gasoil tubes,and now i have better start in the morning and all days--very bad system also for disactivate start&stop-pratically not have separately fuse HOW MUST BE,now i finded in china one programmable 2 timer which can simulate push finger for 1 sec
also i finded a lot of rust on electrical connection on chasis,and they installed many electrical connections screws OVER paint-of course i cleaned all---BUT WE PAY A ALOT OF MONEY FOR ALL THIS BAD QUALITY!!!!!!!!!!!!!
You are correct
6:40 did he did this in purpose ? or not
I have a mondeo mk4 59 plate 2.0 diesel. I'm have no cruise control. I have c41668 and c40168 fault code. Any ideas
The codes don’t tell us much. Have a look at both my videos of how the CAN system works and how to scan the car. The codes translate to U0401 and U0416. Both the ECM and the Dynamic Control modules are reporting loss of communication from a sensor. Buy a diagnostic connector and download Forscan. The Forscan program will pinpoint the problem.
@@NigelEaland found the fault. It was the connection block behind the back wheel on the passenger side for the abs. Silly pass for it as its open to all weathers
@@MrHarty28 well done.
Hey Nigel i have a ford mondeo mk3 diesel engine the doesn't start at all showing the glow plug light on plus it behaving like the battery is low even if you jump start it,what could be the problem
Check the battery connection to the chassis.
I checked it's good,this car went low on fuel and stop,after that i did the fuel bleeding using a hand pump fuel is now reaching the nossel but the nossels aren't opening plus i found out that two glow plugs were not working I replaced all four but the car did start what could be the problem
Eric Ongoro if the engine turns over slowly then the engine management will stop it from starting. Measure the voltage across the battery and then across the starter motor while trying to start. You should see about 10v across the starter. If the battery is good but you have less than 10v across the starter motor then the motor is drawing far too much current. There are two possible reasons, either the starter motor has failed or the starter ring has filled up with clutch dust and jammed the motor, this happens when the dual mass flywheel bearing has failed and the clutch plate disintegrates.
@@NigelEaland i my starter motor has failed let me at a new one from ebay i will let you know,thanks for the advice back here in kenya not many have the knowledge when it comes to ford vehicles
hello, i want to ask something. How many seconds does the glow plug light stay on your screen? In my car it goes out without even turning on for half a second. I will be very happy if you answer.
That’s how it should be. It’s a glow plug test, it doesn’t indicate the glow plugs are on. If the test fails then that light will remain on.
The other lights that go out after about 3 seconds is the same period the glow plugs are on.
The other thing to note is that the glow plugs are only needed to start the engine when it is very cold.
Thanks for watching.
@@NigelEaland Thanks a lot for your answer. I take care of my car thanks to your videos.
hi nigel, sorry to bother you again. I want to ask a question, maybe you have an idea. I checked the glow plugs and it's constantly getting 8.5 volts. When I turn the key, it gives 12.5 volts. but normally it should be 0 volts. I checked the fuse box and relay, it works fine. but it constantly gives 8.5 volts and 60 amp fuse blows. do you have an idea?
@@yunusturan1220 hello again. You have a fault but it should be easy now to work out where it is by a logical process of elimination. The fault is between the glow plug 60A fuse(F4) and the glow plugs. There are only two possibilities, the glow plug control unit has failed or there is a short in the wiring harness between the fuse and the control unit or the control unit and the glow plugs.
Work backwards from the glow plugs. There’s a multi-way plug that you can disconnect them. Measure the volts on this plug. If you still have 8.5v then work back to the control unit checking cable for damage. At the control unit disconnect the plug. Pin 4 is the power from the fuse and should have 12v. Pins 1, 2, 6 & 7 go to the glow plugs and should have 0v. Pin 5 is chassis and 0v. Pins 3 and 8 are from the engine management. Assuming all readings are correct I would accuse the glow plug control unit.
Good luck.
I will do what you said. I hope I can find a solution. thank you very much for your help.
Hi man, i ve ford mondeo 2013 2 l diesel auto
Car is running fine just i have one problem
When i driving car in the heavy rain engine swatched off by it self and then traction control light come on . When i try to start car again doesn’t start , until traction control light swatch off by it self then car start . But traction control light takes time to goes off may e 2 or 3 hours ? Do you have any idea about this problem i ‘d mach a appreciate
Sounds like water getting into the ABS sensors’ cabling or connectors. You need to scan the car for fault reports using Forscan. It will tell which wheel to look at. If the car thinks it’s unsafe to drive it won’t start.

@@NigelEaland Thank you so much for your respond I will do that thank you heaps
check the earthpoint on the gearbox...
I solved the problem. It was the starter motor drawing too much current. Have a look at my video. Thanks for watching though.
@@NigelEaland a slow cranking starter-motor take a huge amount more current if it can turn around,
thats killing them, a slow cranking ( bad batt / starter) can kill other computers in your car.
when you said your only getting 8v at your starter, shouldnt you be getting 12v
No. Resistance in the system plus power draw, drives the voltage down. It's impossible to have the same voltage on a large power draw, such as a starter motor, as provided by the battery. Ohms law says you'd need infinite power supply and zero resistance to achieve that.
My FORD MONDEO 2010 2L DIESEL AUTOMATIC Engine stalls or slows down while driving. It's giving the following two fault code.
P1169 - FUEL RAIL SENSOR IN - RANGE HIGH FAILURE
P1168- FUEL RAIL PRESSURE SENSOR CONDITION LOW PRESSURE.
Can someone please tell me Where is the FUEL RAIL PRESSURE SENSOR located in FORD MONDEO 2010 MK4 AUTOMATIC DIESEL 2L CAR?
If I change the Fuel Rail pressure sensor, will it solve the issue?
The engine slowing and stalling suggest fuel starvation and the sensor is telling you just that. I doubt changing it will resolve the issue. Can you see air bubbles in the fuel line? When did you last change the fuel filter, perhaps it’s blocked or has water in it. Finally there’s the fuel pump and the pressure regulator valve that will regulate the pressure in the rail.
@@NigelEaland Also noticed increased white smoke coming out from the exost. May be injector problem too.
Recently heating was also not working well and engine temp going high suddenly & engine stops. it comes with with P0116 ENGINE COOLENT TEMPERATURE CIRCUIT RANGE /PERFORMANCE PROBLEM.
Changed the ENGINE COOLENT TEMPERATURE SENSOR and that problem resolved. Heating working so quick now. Engine temp gaze working so smoothly.
Hi mate im getting hard starts on cold but does fire up.2 mins on the road and it cuts out its random sometimes ill get a few hours to drive but still cuts out.eney ideas will help alot.1.8 tdci smax is my car🙄
Hard to say. Check the fuel pipe for air bubbles. When was the last time you changed the fuel filter? Fuel filter blockage can cause cut out. Finally buy yourself an ODB2 cable and download Forscan and see what fault reports there are. Have a look at my recent videos about the CAN system.
@@NigelEaland cheers for reply pal.i had full service a month ago .had garage do dino test no codes where stored.🤔dont want to go ford dealer lol they not cheap
crazy col if you had no codes then I would check the fuel line. Part of my bad starting was due to the bleed valve on the fuel filter housing not being fully tightened and air was getting in.
@@NigelEaland ok mate will do and again thanks for the fast reply.if no air in lines could it be cam senser sounds verry likely but i thought id get a code for bad senser.👍
If you don’t have a code then it’s not a sensor. You could check for codes again using the technique I show at the end of this video th-cam.com/video/va-ItdKCl8c/w-d-xo.html

Good old peugeot engines
FORD COMPANY with fill and run system gasoil,without any tap,introduce water on mondeo tank when is raining,and diesel filter is very very bad ,small and bad quality,introduce air on diesel system,that s why after 12 hours mondeo have very poor start-after i changed diesel filter with old model without sensor,and replaced gasoil tubes black with transparent tubes,i have good start,without any air in the system
Hy ! Can you help me to find fuses starter releay . This is for ford mondeo mk4 2008 diesel . Just show me the fuses starter location
It's R1 in the engine compartment fusebox. The fusebox is to the right of the battery and air filter housing. R1 is the bottom left grey relay. See this diagram www.fordwiki.co.uk/index.php/Fuse_%26_Relay_Information_-_Mk4
Before changing relays put a voltmeter across the starter motor and see if it’s getting volts. The starter motors fail on Mondeos also they can get jammed up if the starter ring is full up with dust because the dual mass flywheel bearing is failing.
@@NigelEaland I find the relay fuses starter location wass like you say . In the R1 fuse box . But its not working the engi ne its no starting when i press the start . I bay new starter becouse the old one wass broken. I check it the starter is working. Do you have whatsapp or facebook to call you tomorow to show you live in the video call . My problems . I trust in you i wach all your tutorial video in youtube with ford mondeo mk4 and i see you are very good
