Audi A4 2010
Ok, i'm a new owner of an audi, and i'm not sure if this happens with all the 2010 A4 models...
when i turn the car on, i hear a loud whirrrring noise...
happens for about a minute...and then stops.
what i've been told is that the car has a hepa filter...and when you start the car, it filters out the air inside the car.
any comments on this? thanksss

Re: Audi A4 2010
LOL I did not know there was a hepa filter...
think it only happens if the car is in a drive gear during startup.. otherwise you won't hear it. I think it's just part of the warmup cycle (higher idle speed)

Re: Audi A4 2010
Apparently ( which kinda makes sense). it has to do with the lubrication of the chains on start up, which i was told by service at Audi. I had the same concern at first when i got my car. the only problem i found with it, was that it pisses away oil like stupid.

Re: Audi A4 2010
no no i meant this noise manifests itself when i put the car in gear while it's still in the warmup phase (the first minute after a cold start when idle is high)

Re: Audi A4 2010
My guess, assuming you have quattro vechicles, is it's the fuel pump balancing out the fuel levels between the two gas tanks. Happened on my B5, and happens on my B6 & B7. Suspect the same applies for the B8.

Re: Audi A4 2010
Since its inception, the Audi A4 has been available in four generations, based on the Volkswagen Group 'B' series of automobile platforms. Audi's internal numbering convention therefore treats the A4 as a logical continuation of the Audi 80 lineage, hence the initial A4 was designated as the B5-series, followed by the subsequent B6 and B7, and the current B8.
Of the main body styles, it is (and always has been) available as a saloon/sedan variant, and an "Avant", which is Audi's name for an estate/wagon. The second (B6) and third generations (B7) of the A4 also had a Cabriolet version, but the Cabriolet was not retained for the current fourth generation (B
, Audi now having Cabriolet versions of the related Audi A5 and S5 coupés — and also the smaller Audi A3.
