Audi A4 2.5 tdi (b6)- stange tapping noise?

[martink13]

Hi guys,

First off, Nice forum!

I recently bought a 2nd hand Audi a4 2.5 tdi, but when releasing the clutch (to pull away) there is a loud tapping noise comming from the right side of the engine, it is only there for a few seconds and then goes away. It only hapens when the car in in gear and while releasing the clutch, even if i hold in the brake peddal. does anybody have any idea on what the cause could be?

thanx!
