Hi
This car came to me initially as a non runner...
Fix here: • Vauxhall/Opel Corsa D ...
After got the car running, I was left with what seemed to be the initial fault, something that looked like a misfiring... but, is a misfiring?
Follow me on this video to find out what was the problem...
The car had other issues... and a fault that came up once the engine warmed, lead to the owner to requested to not carry on working on the car...
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

That was a pretty trashed car... I think that both the owner and the previous garage made many mistakes, in servicing the car... what a shame, on a 60.000 miles engine... great video as always 😊 greetings from Italy!!

Thanks!
👍👍👍
Why do people do that oil is simple to change anyone could do it
If you find the car starts misfiring again possibly take a look at the EGR channels running inside the intake manifold. If they start to clog up they will set off misfire codes due to the twinport system involved. Blanking off the EGR stops the misfire but causes a lean condition. I had Z16XEP astra with the same problem. There are conditions which trigger the missfire. All the best.
Yes... have cleaned a few in the past...
Thank you for watching and for your comment!
Good video shows that cars can have many faults at same time which many customers don't believe
Absolutely!
Thanks!
👍
the egr pipe on those engines arrives straight under throttle plate , but side opened.
this will create a heat point and potentially can melt the inlet plastic manifold .. . I had 2 cars like this , one had so sever air leak that the brake booster was out of vacuum after 2 - 3 brakes cycles. the ecu compensate big time via the trims. anyway those hybrid ecu`s are a joke. the vibrations and the heat cycle from the engine just destroy them. the egr pipe cand be cut short or disable the system , kess v2 is ok on that ecu. top job , thanks and all the best!
Thanks for all that info!
👍👍👍👍👍
Excellent diagnosis!!! The last error code is bad timing.i have seen it many times I’m Opel repair technician.needs tools for that and it needs little attention when locking tools.and we never put sealant on any of two egr flange.
Thanks!
👍👍👍
The timing chain vauxhall normal stuff really,and here’s one that happened to me,oil filter,did oil service ,oil lamp pressure lamp started flickering,changed oil filter again,perfect, wtf,,,, good video crazy man thanks.
👍👍👍👍
Thanks!
Nice vdo as usual, I think that the problem of the camshaft is related to the oil pressure , because the camshaft phaser pulley open and lock using the oil pressure
I ve been driving back in 2015 a Vectra C 2.2 dti.
Very high mileage.
200000+ miles .
I left UK and drive trough Europe for around 5000 miles .
I supposed to have done an oil change before leaving UK .
I haven't.
When I came back to UK, I had the same lamp on my dash and in couple of days my timing chain was gone .
Top job as always Luis, maybe some timing chain issue affecting the timing and oil pump ... 👍👍👍👍
Most likely...
Thanks for watching and for your comment Igor!
Did you check the oil pressure sensor? It's commonly leaky on this models.
@@marcelh2341
Was not leaking...
@@marcelh2341 I bet that engine inside was full of sludge, clogging the oil pump pickup and the chain tensioner... I've seen a ton of these
My man!
I think you solved my problem that no one seemed to know

My friend I can’t find the leak, I sprayed some carb cleanser around the egr valve but no difference in engine noise or revs. I have the same car with the same engine and it shows +25 stft when engine is warm but when I rev to 2000 rpm it goes to 0 then slowly back to +25
Any ideas or where else I can look?
I have the same symptoms, lumpy engine, poor fuel consumption
Thanks
A leak somewhere else I would guess..
A smoke test might help...
👍
@@LMAutoRepairs what’s the best vacuum pipe to pump smoke in?
Thanks
There is some nice kits out there... I made my own one...
That said, if you are planning to use it once, probably does not worth the investment...
You better just go somewhere where they can do it for you...
👍👍👍
Great video, tell the guy to put new oil pressure switch in they are not expensive . I have had quite a few of these putting the light on (They are often leaking too ) well worth a try, regards Rich.
Absolutely...
Thank you for watching and for your comment!
Low oil pressure can cause P0016 🙄. Also, especially with these, oil pressure switch causes the ECU to fail. Always check oil pressure switch (and O2 sensor 1 plug) for oil contamination. Then check socket on ECU.
It has been known for the Vauxhall main dealer to quote £2600 to repair this after they have dabbed every plug on the engine loom with oil, even when it can't get to some of the other plugs - clean, new oil at that. I couldn't possibly comment any further.
Thanks for the info!
👍👍👍👍
You are very genius man..

My Peugeot 307 2004 shows misfiring when start especially in the morning and goes off after 25 second.If i drive I goes off. When started it again, works perfect. Changed the plugs no result.But no warning signs in the display.
Any engine noises?
@@plamenm1641 No..Engine quits after 20 second with vibration and struggling. Even if I drive I goes off on the run. But when I start again works perfect. Now I found that after starting drive just a 15 metre and wait for sometime and drive. No engine warning.
Well done Sir Luis great as always
Thanks Nuffz!
oil pressure will be a faulty switch (probably leaking oil into the wiring) The correlation is most likley streched timing chain, both very common faults on that car. I'll bet the chain rattles on start up
Indeed... sensor looked ok...
I have advised what to do next... out of my hands...
Thank you for watching and for your comment Steve!
I had a car running like this.It was the spanner for the timming belt.So the timming was not ok when engine in idle.
👍
Thanks!
Hi where are you based on
You are very good at explaining the faults and it’s findings
Hi
East Anglia...
Thank you for watching and for your comment, really appreciated!
👍👍👍
Great work Luis. Someone did a bad job on that EGR valve 😁 At least that's one problem solved now. Thanks for sharing 👍
There was a blind gasket tested...and after take it off. No big mistake from technician.
That guy anticipate this engine must be take it off as a last option. But this is secret of garage employes.
I know what a blind gasket is. People have been messing around with these for decades. Thing is if you remove it you need to replace it with another gasket. Otherwise you end up with leaks as shown in this video.
You could ear it sucking the air...lol
Thanks Dylan, for watching and for your comment!
Interesting video! Great Job!
Many problems are caused by less experienced technicians ...
Maybe the oil filter is clogged ... (quick test dissemble filter and start)
Greetings from Belgium
Possibly... I advised to check chain/timing and oil system...
Thank you for watching and for your comment!
Nice one as always. I am curious how such a low mileage car can get trashed so badly. Maybe it makes much more sense to get an engine replacement from a donor car.
Probably...🤔
Thank you for watching and for your comment!
I have a strange problem with my 2002 vectra 2.2 dti egr. At idle egr is sometimes commanded 100%.I can command it open and closed with my Autel, it goes to 100%,0%,100% etc like it should, but, sometimes when i command it to 100% it sticks there, even if i command it closed?? If i give it a slight rev it will drop down to 0% or thereabouts.
Now this makes you think egr valve is sticking, but it's throroughly cleaned and moves perfectly!? So why does the egr stick at 100%?
Car starts well, runs well, idles well, just once in a blue moon service spanner symbol comes on for a second. And at 60,70mph it will lose power, limp mode and the service light will come on.
You can easly fix this by getting you'r ecu tuned by a tuningshop. They can switch off the EGR in the software without a problem. And it woun't give you any problems by law or MOT.
Nice video, Learn a lot from each video 👍
Thanks!
👍👍👍
hi, that was an interesting video,can a clogged fuel filter or a weak fuel pump cause that flactuation and lean condition? thank u from South Africa
A question to LM Auto Repairs: I see you have the dealer level VCI and software for most popular cars (eg Lexia 3 and Diagbox for Peugeot/Citroen, ODIS for VAS etc etc...). Yet you use the Maxisys 908 most of the time. Is that just for convenience? I would have thought that if you get a Peugeot, or a Ford, or an Audi in for faultfinding you would hook up a laptop with the Dealer software because that will do more than the Maxisys can. Just wanted to know why you always use the Maxisys first.
Hi
Definetly convenience...
And to be fair, the is very specific circumstances where the dealer tool is actually needed...
Most of the times, Autel is more than enough to help you diagnose and repair...
But is always good to have the dealer tool, for that one time (or more...) where is the only one that can actually do what you need...
Hope it makes sense...
Thank you for watching and for your comment, really appreciated...
My friend gets misfire on multiple cylinders once he goes over 80kmh then it start flashing the check engine light and lose some of it's power even when going slower, usually in the city it has power and runs fine but once on the highway it goes yo limb mode and start hesitating even at low speed , I'm visiting him in Belgium sadly i don't have any tools
Enjoy the visit...😊
Yes, a quick scan should help out identifying the issue...

I havent had my audi scanned, however, someone from a garage came to see it and said the problem might be the comfort control unit, when we checked it, it was indeed swimming in water which left the.comfort control unit burnt. Do u do reprogramming for audi?

How do you be sure that you can short 5v/ground to the signal line without any visible resistor in place? We don't have an ECU schematic so if we are not so lucky, we could burn the ecu.
The voltage reading range is 0 to 5v...
Thank you for watching and for your comment!
@@LMAutoRepairs I think you didn't get my point here. To test the signal reading function of the ECU you shorted the 5V-Rail directly to the signal line. How do you know if there is any current-limiting resistor in the ECU? Maybe it's in the sensor.
@@marcelh2341
My experience tells me there is not...
The ECU simply reads from 0 to 5v...
Not much different as if the sensor gets faulty and shorts to positive or ground...
Or if you have a wiring issue that shorts the signal wire to positive or ground...
Hope makes sense..
He didnt short 5v supply to earth. Instead connected signal wire to earth then 5v. Ecu listens on the signal wire its doesnt supply power down the signal wire. Only a very high value resistor is connected to the signal wire from 5v so the ecu can check for wire integrity. Hope that helps.

Is there anyway you could fix my car please? Or will anyone at your company do as good a job as you?
With opcom plugged in to my car on idle the throttle position jumps from partial load to invalid and all over really any idea what could cause this thanks
Could be a bad throttle body... but you need to test and check...

Had TOYOTA Coralla for 7 years and never had single problem ... bought Saab Bmw Vauxhall first non start issue appeared within one year of ownership...never ever one of tose please ...
When ı erase engine light my motor start working exectly like that
I see a common theme in the many videos of yours that I have watched, people bring cars with little to no fuel-unless the problem requires that you remove the fuel tank.
We get the exact same situation here in Canada so I guess I am not the only one cursing when cars come in with empty tanks, lol.
Keep up the good work making informative videos, thankyou for your teachings.
Yes... lol
It is indeed... I get quite often... is that and bad batteries...🤦♂️

Coil pack or spark plugs
Never likedVauxhall Took one to fix headgasket and now srugling to run when amshaft sensor i pluged in ... camshaft and cranc was blocked with original kit so i thing it is ecu .. but why now went bad???
Double check the timing...

16:05
But advise you to whatch the video without skipping...

I changed but the same i don't know where is the problem@@LMAutoRepairs
If you have changed everything, double check that you left it timed correctly...

@@LMAutoRepairs from the moment I set it, I want programming from the computer or no
This owner was certainly pissed to hear what was causing the misfire, and idiots then resulting in him spending a shit load of money for a leak
Well...🤷♂️

@@LMAutoRepairs I have a Opel Zafira Z1XER, South Africa, with same no communication error ecu U2105. And the same as you with the car coming to me next after other mechanics raped the poor thing. And my diagnosis is same as yours. So it is cool. Keep up the good work and keeping our names as mechanics that know what we doing high. We are in Lock Down now so I cant order anything. It was here before we went into lock down, along with 8 other cars so I have a lot to keep me busy at least while the gates are closed. I work from home, so that is convenient.

Try putting slightly thicker oil, just one grade up
👍
Thanks!
@@LMAutoRepairs By the timing chain having slack at 60K causing correlation code most likely the car didn't have regular oil changes.Engine bearings are probably worn but do check oil pressure and see but I assume car is long gone. Thanks for another great diag video

Indeed long gone...

in UK next step is change the engine...oil problems is the most big issue for engines in this country.
Is expensive to fix it. Very easy to find another engine and swap it with less money then rebuild the engine.
The insurance companies help that.
Of course who knows the reason why to many cars become off road...
