Hi All!
I could use a few pointers as to why my 2007 S3 is running rough.
When I start the car up from cold it almost sounds like it's running on three cylinders with a rhythmic vibration whilst it's on choke at 1100rpm. After 40-50 seconds the engine evens out and sounds a lot smoother - still whilst on the high idle.
I get no warnings up on the DIS and have recently changed my PCV and DV. The car has 77k on it and I'm at a loss as it only happens when the engine is dead cold, once run it behaves as normal.
Any help would be greatly appreciated.
Thanks!
