2002 Audi A4 Quattro Question: cam tensioner
It's called the timing belt tensioner and most likely the tensioner was not tightened properly. If the car has a lot of miles on it should have been replaced. - backyard tech
There is a cam tensioner as well as belt tensioner. the cam tensioner is hydraulic and operates by oil pressure. have the pressure checked since oil sludge and pressure loss is common when synthetic oil is not used. left unchecked this can cost you a motor. doing a t-belt should not create a cam tensioner problem. are you sure the noise is from the back of motor, not t-belt area? - some guy
tensioner runs good no missing but dies. was run 2 years with check engine light and bad cam tensioner.
