thanks for the link mine does not sound as bad as that mine is a petrol engine but I will take a look at the pulley but just waiting for a fine day to take a look just did 300 miles yesterday in it and apart from when its cold did not miss a beat and I was getting 39.1 mpg out of it

hi thank you for your help I did look in the c5 forum but could not find the video would you have a link ?/?

thanks for getting back so that would cause the tapping noise when I accelerate when the petrol engine is cold then ???? is this a common problem then ????

ok I hoping this is a common problem and load of you can tell me whats wrong lol c4 vtr+ 1.6 petrol 2007 1 start engine in the morning and rev engine sounds like tappets rattling 2 start engine and allow to warm up no tapping 3 when engine warm up no tapping at all 4 from cold start engine and rev up tapping is heard but if you hold revs or release accelerate no tapping so its not the tappets so any ideas plz
