Hii guys,

I need some experts in this thing, well I do have a 2004 A8 4.2L Quattro with 55k miles, and there is a very strange noise from my Engine !!

The sound is like (tek,tek,tek) continously and never stops !! its like a diesel engine Sound !!

I really duno from what is this sound, maybe its the engine belt or any other thing in the engine.

So please help ..


Thanks & Regards,

So no one knows about this problem ??!

STRANGE !!!

Hey Dubai, is the noise related to engine speed? In other words, when you rev, does the noise get faster? Is it related to road speed? Like, regardless of how fast you rev the engine, the noise only gets faster if the car goes faster...

One thing you can do, to try to narrow down where the noise IS coming FROM is to take a rolled-tube, like from a roll of paper towels, or some wrapping paper, for instance, and stick your ear up to one end, and point the other end at various places around your engine compartment and/or engine, until you've pinpointed where the noise seems to eminate from. That may help us narrow down the potential causes.

Sorry no one responded earlier. This is one of the lesser-visited areas. Not a lot of us BIGTYME cruisers, it would seem.

Hey AWDaholic ,

Thanks alot for replying, well yes it is related to the engine speed, especially when idle you can here the noise and while pressing on gas while the car is in Neutral you can here the sound gets louder & louder ...

This happens when both reversing and in normal mode, the sound is always there ..

& Thanks alot for replying


My regards

Sounds like you have carbon build up on the intake valves.

Hey auditech79,

Well I should check the intake valves then & I will let you know .

Thanks alot for your reply ..

Hi TommyL,

Yes .. its like a ticking noise .

Well as auditech said he thinks its from the carbon builton the intake valves ..

Dear auditech79,

I have checked the intake valves and nothing is wrong with them !!

They told me I would have a different noise if carbon is added in to the intake valves ..

My sound is like a (CLICKING NOISE) ...

Check your oil pressure, maybe its the camshaft adjusters starvingfor oil.
Other than that i would have to hear the noise to make a good diagnosis.
