Vauxhall/Opel Corsa D Z14XEP misfiring... or not? Fault finding and nearly repair! 

Good video shows that cars can have many faults at same time which many customers don't believe

You are very genius man.. Love you from Malaysia 👍

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

Well done Sir Luis great as always

Nice video, Learn a lot from each video 👍

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.

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!!

Enjoyable to watch and as always good info thanks for sharing brotha. cheeeeeers

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.

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 .

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.

Cool !another one fixed! Gj sir

Great stuff as per usual, top man,

Great work Luis. Someone did a bad job on that EGR valve 😁 At least that's one problem solved now. Thanks for sharing 👍

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!

Great video and well explained.👍

Great video It was very useful thank you very much

Great video as always.thanks

My man! I think you solved my problem that no one seemed to know

Thank U so much 🙏🙏💙💙fan from Algeria

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

Top job as always Luis, maybe some timing chain issue affecting the timing and oil pump ... 👍👍👍👍

Very helpful video

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.

Hi where are you based on You are very good at explaining the faults and it’s findings

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.

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.

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

Can u utilize a 1.4 ecu on a 1. 6 motor

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

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.

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

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.

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.

Que tal saludos my frend , me puedes decir donde consegúiste el programa ? Tambien soy tecnico en México saludos buen video

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.

thanks for your video . do you make training for beginners on your patreon channel ?

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.

Thank you...

ive got this problem with my car right now

Timing chain tensioner is why you're oil light is staying on at 1k rpm

Hi, may i know where your shop is? My audi is not starting . Im guessing its the same with one of your videos where the immobilizer and key fob is the problem

Awesome

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

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.

Thank U. How many km/miles?

Amazing

hello thanks for your videos it help a lot boss i like to ask you i have a same problem but only some times i wonder if you repair cars to and if i give you may email to send you a video so you can see it please let me know many thanks Bekim

When ı erase engine light my motor start working exectly like that

54k miles. What a shame! Opel was nice years ago.

Hi what scaner system you are using? Thanks good video

Where can i buy the Tester tech2?

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 ...

Hi my frd. . I now what problem. U now why show presser sonsor ? Just timing fault. I have same car come to my garage I fix it just timing problem

Don’t suppose you are local to Leicester ... I have a corsa d that needs looking at ...

Coil pack or spark plugs

Also ıf ı pull egr plug my motor working exellent.

Try putting slightly thicker oil, just one grade up

maybe oil pump, maybe crankshaft bearing, which is more probably

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

Is there anyway you could fix my car please? Or will anyone at your company do as good a job as you?

Chain elongated?

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???

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...

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lPRW8F6Sz-w.html could be the issue with the oil pressure..

bit lumpy....ehehe for a tractor

These were just bad engines. Period
