Hi guys,
Recently purchased a Audi 2007 A4 2.0tfsi S-line SE which currently has 56000 miles on the clock. After reading a few common faults, I decided to change the following as a precautionary measure.
-HPFP cam follower
-PCV valve along with the smaller of the 2 hoses
-DV to be replaced soon
Car runs perfectly normal,idle is smooth and is where it should be, I get around 350-400 miles to a tank of fuel which I think is about right. No fault codes.
My concern is when I removed the oil filler cap today there was a slight hissing sound and the idle went rough, is this normal.
There is no oil around the filler cap. The oil filler cap was not difficult to remove.
Many Thanks
Sheldon
