My 300 Tdi has had a ticking/tapping noise since i've owned it.
I've now fully serviced it and fitted new cambelt kit and aux belts.
The noise only happens on deceleration.It doesn't do it on tickover or on acceleration so is a bit hard to diagnose.
All suggestions welcome please as the noise is annoying and i'd like to sort it out.
Thank you

Yes,exactly the same.I was hoping after I fitted the cambelt it might of stopped.
Living in a dream world I suppose!

check all exhaust for leeks and the gaskets could be worn.

Definatley not exhaust as since i've owned it i've put a complete new system on it including de-cat pipe.The noise was there before i put the exhaust on and is still the same now with the new system.

I haven't yet checked them but I was thinking if it was them surely it would make the noise on tick over and when you accelerate ?

I had similar once, check ALL exhaust joints are tight, mine was the exhaust pipe coupling to the manifold pipe. seems mine got a dent on the pipe and bent/knocked the alignment so it was leaking.
