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.
