I have a 2003 A4 Quattro (love it btw) but at 56,000 miles my check engine light came on and the car started to shimmy. The dealer told me it was a coil pack problem. Basically, my 4 cylinder car was functioning only on 3 cylinders. Also, I had a coolant leak at the back of the cylinder head. What I want to know is if this is a normal occurence for this car, basically wear and tear, or are these problems abnormal? What would cause the car to have these types of problems? If anyone can explain this to me I would greatly appreciate it.

 

Sounds like normal wear.
