So now my car started to make a rather loud ticking / click noise when you go to rev, or accelerate. You dont hear it at idle, just on rev or acceleration. Engine oil per dipstick is fine.

car as 118,xxx and is 100% stock.. a4 Avant Quat..
Noticed it yesterday while driving and immediately drove it home, hoping to not cause damage...


Any ideas or similiar experiences with this?

*Edit, doesnt sound like CCT.. fairly certain it isnt CCT

Open up the hood and see if you can tell where its coming from.

Back of the head near the firewall? Probably a cam chain tensioner.

Could be your hydraulic lifters. Try some Lucas Oil Stabilizer (get the correct one).

i know I was starting to leak oil my wife said, upon inspection i concluded it appeared to be output shaft seal passenger side, if that go low I suppose the differential could be making a noise, but I would assume that it would only make noise traveling not at rev...
