Is my engine f**ked?


Recommended Posts

Guys need some advice here. 
 

had a bit of a lumpy idle on friday  for some reason - so i scanned with obd11 and said i had a misfire on cyl1 and 4. I decided to just replace the plugs while i changed the coils on 1 and 4, and also changed the cam magnets today. 
 

when i’d changed the plugs and coils on saturday, i took the car a drive and it seemed to drive absolutely fine but just had a poor idle.
 

there are absolutely no errors now on obd11 when i scan it but there is 100% an issue given the above. 
 

I’ve tried to look on fb groups for help but it’s not going anywhere. 
 

apart from taking it to a garage to look at - is there anything i can do to check if it is a timing issue with obd11 - i.e value’s to take with live data, or is there anything else anyone can suggest as to what the issue may be ir if there’s anyone had anything similar?
 

i did take a live data of the camshaft adjustment intake values but not entirely sure what i’m looking for as trying to find the info to translate it is difficult.  Here’s a screen capture of that data. 
 

if anyone can point me in the right direction i’d appreciate it.

when i’d changed the plugs and coils on saturday, i took the car a drive and it seemed to drive absolutely fine but just had a poor idle. I did give it a little bit of beans and all of a sudden i lost all boost and seen a puff of black smoke behind me - the car did drive ok but just no boost whatsoever. I checked the hotside and cold side of the turbo and everything is fine, no play in the impeller, wastegate functions as it should and the wastegate flapper is still there. After doing the cam magnets today i started the car, have boost as i can hear the turbo spooling now but i havent driven it anywhere - literally just started the engine and it still idles shockingly and i’m worried that maybe there is a timing issue or something like that.

If you are really concerned it maybe timing slip, you may want to recover it. Especially as it is still running now.

 

but if you want to

 

Search for camshaft phase adjustment or something like that. What does it show when engine is warmed up?

I havent even waited for the engine to warm up because the idling is so bad. 
 

i’m going to just have to get it recovered to a garage and see if they can pin point the issue. 

Yes. Maybe safest. So long as they know what to start checking before causing any further damage.

Been doing some further reading and I reckon i might have a fueling issue. @Bingodalton has some great information from previous threads on injector failures/issues and i came across a few bits of information about the hpfp. 
 

I just went and took off the oil cap and the oil smells of petrol, which as far as i can see is one of the symptoms of hpfp failure. The car struggles to start, again, an hpfp symptom, misfires when it does, another symptom. 
 

Could the hpfp be the issue and it’s been a fueling issue all along and not a timing/sparking issue? I will get the car to a garage to check the car but this makes me feel a little “less” worried if its something as stupid as a fuel pump issue….

Your initial symptoms all point towards an injector fault....pretty common tbh

Speak to Tom Walker at Retro Resus  or Will at VRS. 
 

I would get it recovered to a specialist before you potentially cause any damage.

 

I had a dodgy injector years ago on my stage 2 R and no fault code was showing...caught just in time on just 32k!

Yes could be. You can monitor high pressure readings and there may be some injector values to check. But unless you really know what your doing prolonged further use could cause further issues. 

 

If you want to you could remove plugs inspect, if you have a borescope to put in cylinder and see how wet, even better.  Good luck. Let us know how you get on.

Car is now booked into ecotune on the 15th. Spoke to both Marcus at VRS and Tom from RetroResus - both absolutely spot on and took the time of day to entertain my questions. Both reckon it could be a faulty injector stuck open  - and Tom also suggested valve springs. They said it could be the hpfp but thats not that common on the mk7 apparently. I just hope with all the new parts i’ve put on and running it a few times it hasnt done permanent damage to the engine. 
 

ecotune have an injector tester so hopefully that confirms thats what it was all along. 
 

i will update this post once it’s been diagnosed by them incase anyone else has any similar issues in future…..nothing worse than reading a thread about an issue you’re having and the OP dissapears!

Glad they were of help. Tom quickly identified my dodgy leaking injector....it wasn't stuck open thankfully but at idle it was giving the odd misfire.

 

I replaced all 4 ...belt and braces as the labour needed to change 1 meant if another failed down the line it made sense to change all 4.

I did pull plugs 3 and 4 yesterday (3 which has no misfire, and 4 which had the most misfires) and there was no fuel sitting on top of the piston from looking down the spark plug hole.

 

the tip of the plug on 4 was a lot blacker than 3 and they’d all only just been changed on saturday…..so i dont know whether there’s maybe a sticky injector rather than a leaky one, and maybe still an issue with the hpfp given the smell of fuel in the oil. 
 

who knows - will find out in 10 days

This sounds similar to what happened on a Sirocco I had.

 

Turned out the timing chain had slipped, & in doing so also blew an injector & fuel pump

Oh dear - i hope not 🤦🏼‍♂️

Little update. I changed the cam magnets to no avail. Car is now in ecotune today and so far they have replaced the cam valves (which make contact with the cam magnets) and the timing now seems to report as correct and in sync. They’ve also removed the injectors and tested them all and they all appear to be absolutely fine. They are now in the process of removing the fuel from the tank as it could be contaminated fuel. I did fill the car up with some morrisons super 98/99 rather than my usual tesco momentum, and the car had used 3/4’s of a tank when this issue presented itself - so i’m unsure of whether there’s been dirty fuel/contaminated fuel/water on top of the fuel and now that the tank was so low the issue has presented itself. Hopefully i’ll know soon - i have a very expensive bill coming up currently whether the issue is fixed or not.
