2011 2.0tfsi engine whine

[Simon b1]

Hi all,

I purchased my 2011 A4 2.0 tfsi 4 years ago and it’s always had an engine whine when revving. Kind of like a belt noise.  Someone recently said I wasn’t right and to get it checked. I’ve always thought it was normal as there is no loss of power and the auto box is still seamless. I took it to my local garage and they weren’t sure as the tfsi engines are always noisy and advised going to a specialist. On another Audi forum most people said that there a4’s made the same noise and it’s normal. I’m now paranoid and was wondering if anyone else has had the same noise and if it’s normal or an issue? Thanks for any help.

If it's been running fine with the whine for 4 years without problems then I'd leave it. Only get it looked at if the noise gets worse. If it ain't broke don't fix it as the saying goes.

Thanks. That was kind of what I was thinking. Wait until a loss of power or whine getting louder.

Sorry, and certainly not wanting to disagree with Steve’s comment, but just to add another school of thought, and that would be that if anything is making a noise, then it’s trying to tell you something, and it should be investigated. 
You obviously want some reassurance from us Simon so:- 

So come on those members with the 2ltr TFSI engine - please help our friend Simon out with some experiences. 
Kind regards,

Gareth.

Hi,

Might as well add my pennies worth - could be worthless.

Quick diagnoses, open the engine bay.  Do you get the whine on idle?  HOLD the engine at higher revs, does it whine?  Does it only whine on acceleration (or deceleration)?  All of this could rule out the gearbox?

Can upload an audio clip of the whine?  It might be difficult to hear / record.

Not a whine, but a squeaking noise, but when was the timing belt changed and all the ancillary parts?

How many miles on the clock?

Thanks, Joe
