Hi all, been a while since I posted here but I'm at my wits end with my current B8 Avant..
I bought it in March this year, 09 2.0T FSI Avant and after a few months I started getting issues with misfires and running on 3 cylinders..
First time it happened I thought I was running out of petrol. It was pretty low on juice and seemed to stutter a little. I pulled into the petrol station, put some in it and it was very hard to start afterwards..
When it did eventually start it was only running on 3 cylinders and there was lots of whitish smoke with a really strong smell of unburnt petrol.
The mechanic came and diagnosed it as a coil pack failure on cylinder 3 but when he changed it it made no difference..
I decided to try and drive it home, it was stuttering and chugging with the engine management light flashing and the epc light on too. After a bit I tried to really floor it to see it it would help.. And it did, seemed as if when it hit 4000rpm it just sprung back into life.. The mechanic reakoned it just needed everything cleared out after the coil pack change...
The mechanic also did a service and changed all the plugs the following week as he said they didn't look great..
Fast forward a few weeks and the exact same problem.. Chugging, flashing engine light and white smoke belching out the back.. This time cylinder it was cylinder 2..
Mechanic comes again with another coil pack but this time it really doesn't fix it at all so he changed the injector and away it went..
For another few week.. Then same prob on cylinder 2 again.. Went to another mechanic this time, told him the history and after a few days he came back and said it was a faulty camshaft actuator plug, changed it and said that was it sorted..
Same thing happened within 10 mins of collecting the car, went back to him and he done a lot of stuff with it on the computer and said he needed to reset some sensors or something like that and gave me the car back again..
It seemed OK after this for about 3-4 days then on the weekend past it did the same thing but only very briefly,.. It chugged, engine light came on and then went off again after a min or 2..
Has anyone any idea what could be wrong.. I'm at my wits end with this car and no longer trust it.. I'm just always expect it to break at any minute
Thanks
