Im a newbie to the site and really should have got on here ages ago!
Ive recently bought an A3 and had nothing but trouble and a hole in my wallet
Basically after pruchasing my wicked looking vehicle it has developed a problem where it keeps going into a safety mode limiting the revs
Also now it intermittently starts to judder, this starts off quite subtly but then becomes a really heavy jerking from the engine.
Once you turn the car off and on again its reset until it happens again.
The problem only happens when on longer runs and doesnt always happen.
Ive had a new head gasket and a brand new head put on the car and a new injector all mounting up to over £2k!
Thing is im not sure its fixed and its really driving me nuts
Do you have any ideas what it could actually be?
Any help is appreciated
