- Showing whats involved in removing and replacing the EGR valve and how to free it from sticking.
If your Volvo v50 2.0d suddenly suffers from loss of power with lots of dark smoke from the exhaust it's a sure sign the EGR valve is sticking open.
Sir, because of your video, i have the courage to do the egr cleaning.. your video is the only video that explains the bolt under the egr and where it is. I will do it this weekend and i will let you know. Big Salut 💪🏼
Thanks for the comment, When flushing the valve shaft clean, be careful not to get to much cleaning solvent etc on the spindle going into the motor, good luck.
Hello, have you done the procedure? How was the result? And were there too many institutions? Did your performance increase as a result?
Thank you for the advice John took mine off and cleaned today. If I had not of watched your video I would never of known about the small bolt under the EGR which like you said is a pain to undo because it is an Allan cap head, but I took your advice and replaced it with a new Hex bolt, much easier to do up.
Sean O'Callaghan, Nice to no the video helped, thanks for the comment.
What size Allan key
@@nikkilambie5659 5 or 6mm I think.
My good lord 7 hours cutting an alien key down 4 arguments between me and the husband much swaring and cussing but the bloody things off..... thanks video amazing cheers. Its so dirty husband trying to clean now
I like the spanner with the string idea!
Very smart indeed!
Reminds me of my Mitts with the wool sewn onto them going through my sleeves over my shoulders to stop them getting lost back in the day as a Kid! Lol! 👍🏻
Thanks, I learnt the hard way :(
6:50 I knew it i knew it! i tried to remove this bastard and i remove all the screws! i thought.... so there was another screw after all! i did feel something down there, but since i looking for a hexagonal screw i couldnt understand what i looking for. its stuck... so now i know! thank you very much sir, you should have a medal for this..
Filip Wiberg, Thanks for the comment, nice to know my video helped.
Nicely done. Respect! Thanks for the video!
Thank you too!
If it was at the front of the engine, a 10 minute job to remove!
Always placed at the most awkward part of the engine while it being such a common issue!!!
Good Video, Thanks!
Yes correct, this is a peugeot engine used in a few different makes of car, probably easier to get access in some.
Thanks for the excellent explenation!
Alex Rossenthal, Nice to know the video helped, thanks for the comment.
good work looks like a new valve!
BadgerLaser, thanks for the comment, I cleaned the valve and valve seat using scotchbrite soaked in WD40
I believe I may have the same issue on my 2008 V50 2.0D, last couple of weeks has been very hesitant with acceleration, cannot feel the turbo spool up like it normally does and just feels gutless all the way through the rev range. It is however intermittent, sometimes I have power and then other times I drive it and it's gutless. May attempt the blanking off to confirm before attempting to remove the valve, looks like it's a bugger to do! Thanks for the video.
Luke Fearn, Yes sounds like EGR valve sticking intermittently, Good look.
Hi did this resolve your error as I have a similar prob
@@richardgjkingshotte Hi Richard, I never got to the bottom of the issue, ended up part exing it. Cheers
Hi John. Fantastic video. Thanks for sharing.
I have a 2007 Mondeo which uses this engine, albeit with a DPF. In the Mondeo at least, blanking the EGR valve does not cause an error code and it's advised to leave the EGR plugged in.
What I did find, however, is with the EGR blanked, the engine ran much much cooler and would take much longer to warm up which was not only uncomfortable in winter, it also reduced my fuel economy. I tested this over 30,000 miles and then recently removed the EGR blank. Since removing it, the engine warms up quicker, runs slightly warmer, and is actually slightly better on fuel as a result. Also, any performance decrease from having the EGR in place is negligible. I have read the live data from the engine and when at light throttle or no throttle, the EGR is open and allowing gas through. But, as soon as you floor it, the valve closes within milliseconds to ensure the engine only breathes clean air when more performance is needed.
The car is on 221800 miles and is still on the original engine components including clutch, DPF, EGR, and injectors.
I will be removing the EGR more so out of curiosity to see what it looks like.
Little tip, if the clamp on the big silver EGR pipe starts to fail, the newer design from Peugeot is a a screw down rather than spring clamp, and they're about £6 on ebay if you search for 2.0 HDi EGR clamp.
Happy motoring.
thanks for the comment
Thanks! Good information :)
Leremias Arnold, Nice to know the video was helpful.
Great help Thankyou
Jay Diamond, Nice to know it helped, thanks for letting me know.
Great video thanks
Aman A, Thanks for the comment.
Great video. Going to take mine off and clean it tomorrow 🙏🏼
Thanks for the comment.
It wasn’t the EGR valve which was the problem. Albeit was a bit dirty and I gave it a clean. I have a faulty Turbo Control Valve which isn’t letting the turbo spool up.
@@oldy1984..hello, did you manage to fix your problem. I have the same thing i gues. I have 2 codes. P1335 (this is for the EGR position minimum stop) and P2263 (this is from the turbo vane where i have high voltage on it when i accelerate).
@@claudiutanase2223
Hey. It ended up being a faulty turbo actuator(waste gate) Replaced that and the problem was sorted. It’s back at the garage again now with a problem where there’s air getting into the fuel line from somewhere 🤦🏻♂️
@@oldy1984.. sorry to hear that. I had a similar problem in another car with air in fuel lines. But this hapend when one of the pipes was broke and i try to make som adapter but i think the pressure is very high and from any small hole its taking also air. I manage to solve the problem by changing the line with a same one witch i buy from a scrape yard
Hello John, I only have the egr unplugged but sometimes I get the engine service necessary message and then the engine loses power and emits black smoke. Would it be better to put a blanking plate and plug in the egr, or is it ok just leaving it unplugged? Thank you
Hi, It might depend on the year of manufacture, our 2006 model runs fine with the egr unplugged and no blanking plate fitted, but you first have to make sure the valve is fully closed before unplugging it, only way to be sure valve is fully closed is to remove it then clean both the valve stem and face to make sure the valve face is making a good seal, then refit the valve without plugging in the connector. You can try fitting a blanking plate in case the valve is stuck open a bit but the valve will need to be unplugged.
Note: I have had to resort to running our car with the valve unplugged due the valve repeatedly getting stuck, it also runs fine with the blanking plate fitted providing the valve is unplugged, but if the blanking plate is fitted when the valve is still plugged in a warning light shows on the dash. Two years ago after the last removal and cleaning of the valve I refitted it without plugging it in, it is now running better than ever, with no warning light and low emissions.
Do you need any gasket/sealant between the egr pipe and the egr valve?
Aman A, No sealant or gasket is used on this joint, if the flange faces are marked in any way then some sealant will be needed.
Hello, was there a noticeable performance increase after cleaning the egr valve? I'm very curious about this. My vehicle also has a 30% performance drop some days. Sometimes, but rarely, there is acceleration as I want. I think a valve is not doing its job or is clogged.
Yes if the egr valve is sticking there will be a very noticeable loss of power.
@@johnbower I will do this as soon as possible. Thank you very much. Thank you for showing all the details and putting in the effort. I hope everything goes well.
Excellent video John. I think this is the problem with my engine but not sure. My engine runs sweet however there is no power. I hope it is this and not my turbo, is there any way to prove either way?
Thanks in advance
Rob
Hi Rob, What I did to prove if the problem was related to a sticking EGR valve before removing it, I blanked off the pipe from the EGR valve to stop any exhaust gasses passing. I do show this in the video. thanks for the comment.
@@johnbower Hi John,
It was the vacuum hose in the end. Thanks for your help buddy 👍🏻
Not sure but you engine bay looks different to mine I have a 2012 5 cylinder V50 d3 r design would it be the same as yours? Ps mine don't even have a dip stick for oil
Volvo in video is a 4 cylinder 2 0d 2006 model, completely different engine to yours.
Did you check that you didn't have any boost pipe leaks, causing the engine to run rich, which then would make a lot of soot build up on the egr valve, making it stick?
Aman A, No problem with boost pressure and definitely no leaks.
Note: If there were any serious boost pipe leaks (this would not cause the valve to stick) boost pressure would be lower, therefore less pressure to blow exhaust soot past the valve stem.
@@johnbower I thought if there was a boost pipe leak, the fuel/air mixture in the cylinders becomes too rich.... the exhaust gases would become more rich/sooty, and this would build up on the exhaust valve/egr valve more quickly.... I think you are thinking of the air intake pressure being lower (not enough clean air going into engine)?
@@amana1480, When the EGR valve is open there is an open passage between the exhaust manifold and the inlet manifold, so the pressure in both the exhaust and inlet manifold will be equal, therefore any drop in pressure due to a leak in a boost pipe or the intercooler etc will also be lower in the EGR valve, so less pressure to blow soot up past the valve stem.
Did you get any fault codes or dashboard lights when the egr valve was sticking open/malfunctioning?
Aman A, No fault codes or warning lights were showing on the dashboard.
@@johnbower Thanks for replying
Was it's just not boosting
13:47 What fault were you getting? Did the blanking plate put any lights on the dashboard? Couldn't you just permanently blank the egr instead of taking it off and cleaning it?
Aman A, With my car no faults showed with the blanking plate in place, but I do believe with some cars dash lights would show.
@@johnbower Thanks for your reply. How long did you leave the blank on for? What year is your car? Does your car have a DPF?
@@amana1480 Car is a 2006, with no DPF, blanking plate was only on for a couple of weeks until fixing the valve,
Nice video. Did you not get any error codes with the egr blanking plate on? Is the difficult lower egr allen bolt 5 mm?
Ma Va, With the blanking plate in place, from memory I do recall getting a message in the display, but there was no problem with how the engine performed, but if I also disconnect the wiring plug from the egr valve there is "no message" in the display, but if you plug in a diagnostic tool an error code does show, but there is no problem with how the engine performs, if anything I do believe the engine performs better without the egr valve. The lower difficult setscrew is 6mm and requires a 5mm Allen key.
Thank you for the comment.
@@johnbower have problem with my v50 2004 2.0d
all works perfectly but some day it started lost power and i got message engine system service requied
What can it be, and does repair is too expensine
Would like u answer me it would be thankful
Hi guys!Does anyone experienced coolant lose on these engines?!I need to top up coolant around 200-300gm every 2-3 months.No external leaks.EGR cooler?
@@zapadnasrbija9460 i got the same message, that would be a egr problem, if you have some tools you can fix it for 100$ or less.
@@johnbower one month later after I bought my V50 I accidentally discovered the plug hanging around. The engine run perfect.. so I just let it be. Someone did that for a reason I guess 😃
5:40 How did you clean the valve sealing area?
Aman A, I cleaned the valve head and valve seat using scotchbrite soaked with WD40
7:34 Can you remove the cover and wiggle the valve with the egr valve on the car?
Aman A, Yes you can remove the plastic cover and wiggle the valve until it shuts, but that will not rectify the problem unless you are prepared to have someone sitting under the bonnet doing this every time it sticks :(
Note: Best quick solution is wiggle the valve until it shuts, then unplug the wiring from the valve to prevent it from opening :)
Hello. What fault/symptoms were you getting? How long did your repair last?
Aman A, Fault symptoms as follows: Almost total loss of power / Engine not wanting to run / Clouds of black smoke from the exhaust pipe.
You ask how long did the repair last, I have had to remove the valve and clean the valve stem on three different occasions :(
@@johnbower Why don't you blank it permanently?
Hi John. Did this bring on a warning on your dash
“Engine system service required” any advice would be appreciated. Martin
Hello Sir..i have a v50 from 2008,i had dpf and egr off because my motor oil contaminated with diesel fuel..problem fixed..
But now when i accelerate i have a lot of black smoke..if i hold it to 3000 rotation constantly i still have smoke..on the egr i obtured with a metal piece..after many months i still don t know what is my problem..sorry if my english is bad
mihai radu, It seams like air flow restriction to the engine.
If it is not the egr valve at fault check out other things that can restrict air flow.
(a) Check out the air flow shut off flap located inside air intake pipe just before inlet manifold, this flap may be stuck restricting air flow.
(b) When was the engine air filter last changed, this will restrict air flow if dirty, note: if you have had problem with dpf contaminated then catalytic converter could also be contaminated creating back pressure in exhaust manifold, this back pressure gets released backwards upstream into the air filter every time the engine stops and contaminates the air filter.
(c) If there is no restriction with air flow then the engine is getting to much fuel so could be a problem with injectors.
Good Luck.
@@johnbower i have egr off from soft..and i put a metal to obture the pipe from egr..i tested return of the injectors,all 4 have the same return but i didn t tested them on a test bench..now since it is cold at first start it sound like a tractor,relanty instable and shacking for at least one minute..i like the car itself but the engine is very upseting..thank you very much from answering me.
@@mihairadu3031 Did upp solve problem with black smoke? I also have Volvo V50 2.0d DPF EGR off with black smoke issue. 😕
@@hidosmedo5732 hello,i almost solved,i have 20% of the smoke i had before,it was from injectors,check injectors, i had patience until with a friend i decided to repair myself
@@hidosmedo5732 because i didn't change all injectors,i changed only 2
Thx
No problem
Any tips to undo that nuisance Allen screw, I spent 6hrs trying! 😫
Wayne Norman, 5mm Allen key needed, cut short end of Allen key off shorter this helps to avoid some obstacles and get the key into the bolt end, Note Allen bolt only needs undoing a couple of turns then it will slide out of slot. If still struggling it gives a lot more room if the battery and battery box is removed, but that is not easy, Good look.
Thanks John, round 2 today...I'm feeling positive. As soon as it's stopped raining I'll be there. I read the chapter in Haynes manual last night, what a nightmare job if done step by step, jacking the engine, pushing it forward etc. I Don't have the smallest of hands but I'd rather try your way first. Thanks 👍
I ended up usuing Torx to remove the allen screw. Gives i bit more flex, easier to get into screw
do i need to drain the coolant if i remove the egr cooler?
Tide Hunter, Best to drain coolant first from draining point bottom nearside corner of radiator, if you don't it will spill all over the place. When re-filling with coolant you need to bleed air out of the egr cooler using bleed screw in the rubber pipe just above the egr cooler.
@@johnbower Thanks for the tip John. Just wondering is it possible to drain just half amount of the coolant. Just enough to drain out whatever is in the egr cooler
@@ChrisUK_22 If I where you, Just drain it from bottom near side corner of radiator until it stops running out because there will still be some coolant trapped in the engine block, this has to be drained from a plug screwed into the back of the engine block, but this trapped coolant should not cause a problem in your case, note if the coolant is the original Volvo coolant it can be re used because apparently Volvo coolant does not need to be changed, when draining the radiator place a wide container underneath to catch it. Good luck.
Why would you want to remove the egr cooler?
Do you know the size of the allenhead?
jorgubb, The Allen head setscrew is 6mm thread and requires 5mm Allen key.
@@johnbower Thank you very much. I finally got it of, it was a real pain.
priceless!!!
Phillip Winther hansen, thanks for the comment
I am just about to do my EGR on my Volvo V50
How much would you charge to do this on my car?
Aman A, Due to recurring problems your best solution is to remove the cover wiggle the valve shut then unplug the wiring from the valve, the valve will then not be able to stick open causing a mass of pollution, also the engine will run much better with the valve set in the closed position :)
@@johnbower I removed the cover with the egr valve on the car, and the valve/mechanism feels like it moves freely without sticking
Would the EGR valve be the issue if the car seems underpowered? I dont get smoke ... just seems underpowered
Nathan suley, best way to check if the EGR valve is at fault without removing it, blank off the pipe that fits between the EGR valve and the inlet manifold, undo the two bolts that hold the pipe to the valve and slide a thin flat piece of metal between the flange on the valve and the flange on the pipe to block off any flow through the pipe, two holes will be needed in the blanking plate for the bolts to pass through and be re-tightened, if there is improvement when the blank is in place then the EGR valve is sticking open.
@@johnbower thank you John... you should sell them :-)
I would buy one 👍🏻
3:28 Yes a poor design definitely, prone to making the valve stick open.... did you lose a lot of power and mpg with this fault? I wonder why they didn't design it so the motor moves the valve to the closed and to the open position.... I wonder why they relied on the motor to open the valve, but a spring to close the valve...
Aman A, Yes with the valve sticking open a lot of power was lost making it difficult for the car to be driven.
There is nothing wrong with using a spring to close the valve, the problem lies with the cam design which creates side loading to the valve stem causing it to stick due to soot build up on the stem, also the valve stem bush is too far down the valve stem giving the cam more lateral leverage on the valve stem.
First thing needed is a well designed seal made from PTFE to stop exhaust soot getting up the valve stem, secondly the valve stem bush needs to be closer to the end of the valve stem, this would then rectify the problem, but the EGR valve manufactures would then loose out on there replacement sales.
@@johnbower Agreed
It’s basically fighting against the run of play as they say!
Better if it was an offset cam favouring the return with the least resistance!
Design fault favouring the Main Dealers no doubt???
Hi I know is an old video but did you have any problems putting back the aluminium bottom part to the intercooler where the rubber seal is on? Mine doesn't want to go fully in. I tried to screw in but it just bends the plates.
