Hi there. I've spoken to my indi about this and he said its normal and sounds no different to any other 3.0tdi he has heard or dealt with but I can't believe this as I've never heard this on other audi 3.0tdi. (There are at least 3 q7's which drop off at school and I've never heard them do it.

Basically it sounds like a constant tick, tick, tick which seems to speed up with the engine.

I've only noticed this in the last few days as I have had the window down. If the window is closed I can't here it at all

Any ideas. My indi days it's not the chain. Which I guess would be a rattle not a tick
