Hi,

I have an Audi A6 1999 Avant 2.4 petrol. Low milage.

A rattle has just developed yesterday coming from the engine. To me
it sounds like one or more tappets but the guy from the AA thought it
might be the water pump or fan belt tensioner (he was called out over
an unrelated issue btw - dead battery). The noise seems to be coming
from the front/top nearside of the engine. It is audable while
driving at low speeds but is drowned out by the wind at higher speeds.

The car had a service a month ago and has not been used much since
then. I took the car for a good run but the noise did not go (In fact
it may have got slightly worse). The oil level is fine.

Is there anything I should check before sending in the garage? Should
I not drive it in case something breaks?

TIA. Mark.

Try to locate the noise by holding a piece of tubing in your ear and the
other end against where you think the noise might be coming from. What
you've told us so far is far too vague.

Without examining the car, its very difficult to tell, but the V6 is prone
to both water pump failure, and cam drive tensioner failure, both of which
can (in case of w/pump) and will (in case of tensioner) lunch the engine, so
personnally I would not drive the car until its been properly checked.

IF it's coming from the cambelt tensioner or waterpump, it can wreck the
engine, Ring round your local garages to get a price for a cambelt &
tensioner change before you take it in, the price varies dramatically.
