My VW/Audi specialist said near word for word what yours said, so left me in a bit of a condrum!Having read Sarge's excellent piece on the subject https://www.a2oc.net/community/index.php?threads/general-a2-servicing-information.23606/page-2#post-267826 I asked my totally honest garage owner for a quote for replacing the oil pump chain, tensioner, etc on my tdi75 and met with some ridicule: 'never known one to fail....big and expensive job to replace....in the very unlikely event of a failure you could get a lower mileage replacement engine for less' and so on. But like some other contributors to this thread I would like peace of mind for long journeys.
The car has done 152K miles and I assume it hasn't had the chain replaced. The last owner took good care but I have no means of knowing what went before. I can hear no rattle in the engine at all.
I would be very grateful for members' views on how many AMF engines are running happily at 150-200K miles without having had the chain replaced, and also on whether one could hope to get warning of impending failure. Is there usually a rattle or increased vibration, for instance?
