Poor Tolly. Sitting not getting used much in down to -25C temps has obviousley messed with her sensibilities a bit.
I'm starting a new thread to see if I can get some answers from experienced posters or mechanics. Please refrain from the usual "could be this, could be that" posts. Sorry to sound a little negative when asking for help, but I have spent hours trawling the various VAG forums, and confusing myself. There is so much conflicting info out there, and posts from those that are obviousley just poking about under their respective bonnets.
So to the symptoms.
AE AEY had been running peachy, but then noticed the slightest hessitation whilst driving up a gentle incline. It cleared itself and didn't do it again for the rest of a fairly long journey. Having been aware of the V5 (and VAG in general) coil issues, I thought it would probably be one of them on the way out.
Next time I used the car it ran for 5 minutes in it normal creamy smooth manner, then started missing pretty badly. Very much felt like a cylinder was down. ECL on and flashing when I gave it some gas. It got home though. Note that it was still running rough as a badger whilst at idle.
Once cooled down I checked the coils and indeed no.2 was in bits. So ordered a new Bourgicord one. (Mines a 170BHP 20v BTW) Fitted it, and she was back to idling perfectly. Also it would rev through the whole range very cleanly. Guess the new coil is behaving properly. HOWEVER, I took her for a test run and as soon as the engine temp started to rise, she started to misfire again. Only slightly at first, but as temp reached normal I had a very strong mis at around 2000rpm. I kept my foot in and got the revs over 3500-4000 it was much better.
First question. Does the car need to be put on VAGCOM after a coil pack has been replaced?
Second question. As the car now idles properly, and drives fine whilst cold, this to me would suggest the coils are now working as they should. Would you agree?
Third question. Does the misfire when warm suggest that my car is ready for its third MAF of its life?
Forth question. Can a MAF be replaced without resetting the ECU via VAGCOM?
Fifth and final question. I have read about temp sensors, and lambada probes leading to similar issues. Can these be islolated without resorting to VAGCOM (PS I was being funny about the la la la lambada probe.
As mentioned above I would be very very greatful that answers are given by those that really really know thier VAG onions. As I am in Austria, those kindly folks out there with VAGCOM that can do diagnostics down at the local Macca D's car park just don't exsist. The local VAG dealer can do it, but are going to charge me the earth just to plug her in and get the codes. Also if it is the MAF or Klapper, as the call it here (oooo dear missus me cars got the Klap) then the bill is going to be massive. Around €500 at the least. Simply not worth it.
Hope a few of you with grease under your nails can help,
Kind regards
Larry.
