UBM Posted November 25, 2006 Report Share Posted November 25, 2006 Thought this was just a B6 problem? Link to comment Share on other sites More sharing options...

Korkster Posted November 25, 2006 Report Share Posted November 25, 2006 Interesting reading - I have noticed the whine on mine aswell! But I don't have a S4! Link to comment Share on other sites More sharing options...
the911sc Posted November 25, 2006 Report Share Posted November 25, 2006 I think i remember hearing of a tech bulletin on this ( for S4 at least) and its to do with air pressure in the intake under cold start conditions.. I think an engine ecu flash is available for this; go see your dealership Link to comment Share on other sites More sharing options...
dodgy Posted November 26, 2006 Report Share Posted November 26, 2006 Does it sound like your car is running on a turbine? Mine does this too (B6) - I find I quite like the sound. Link to comment Share on other sites More sharing options...
DaveJ Posted November 27, 2006 Report Share Posted November 27, 2006 I get the whine but it only lasts a few secs.... (B7 S4) Link to comment Share on other sites More sharing options...
Scotty Posted November 27, 2006 Report Share Posted November 27, 2006 If it's this noise then there's a service bulletin for the fix. Mine suffered with it when it got cold. Link to comment Share on other sites More sharing options...
Drewcam Posted November 28, 2006 Report Share Posted November 28, 2006 No problems with mine yet, but i have allready printed off the bulletin just incase it does start Link to comment Share on other sites More sharing options...
macdond Posted December 6, 2006 Report Share Posted December 6, 2006 Drewcam Due you have a note of the service bulletin for this fix. Link to comment Share on other sites More sharing options...
Drewcam Posted December 6, 2006 Report Share Posted December 6, 2006 I got it from a previous thread on here. I will have a look back but i'm afraid i do not know how to link you there. Link to comment Share on other sites More sharing options...
Drewcam Posted December 6, 2006 Report Share Posted December 6, 2006 (Currently) on page 18. Sam D's thread named "high pitched whine on start". John Carter has replied with a link to the bullitin but i can not get it to work now. Perhaps JC could help out with another link to it Link to comment Share on other sites More sharing options...

macdond Posted December 22, 2006 Report Share Posted December 22, 2006 911SC Spot on with your responce to flashing the ECU with a new version. After many discussions with Audi and me providing evidence of the noise they have told me the following: Audi Technical say that the problem is related to ECU programming and the inlet manifold. Not sure exactly where the manifold gets involved, however glad they are going to do something. Now just got to wait until they get the disc from Audi Technical. It makes my blood boil when I pass all the useful help you all give to the dealers and they still will not do anything until Audi Technical get back to them. In this case it took over two weeks. The words yeah right, I smell comes to mind. Link to comment Share on other sites More sharing options...
hashluck Posted December 22, 2006 Report Share Posted December 22, 2006 They said the same about mine (ECU and inlet manifold) but it did not fix it and they ended up doing another technical bulletin (to do with pulleys) which I told my dealer about in the first place. This bulleting is well documented on here somewhere (maybe even in this thread but I do not have time to look right now). Good luck! Link to comment Share on other sites More sharing options...
PetrolDave Posted December 22, 2006 Report Share Posted December 22, 2006 [ QUOTE ] Audi Technical say that the problem is related to ECU programming and the inlet manifold.

[/ QUOTE ] There's a flap in the inlet manifold that moves to create a turbulent airflow for better torque at low revs, and a clear airflow for better power at high revs. However, this whine has usually been caused by the pulley problem already mentioned.

Drewcam Posted December 22, 2006 Report Share Posted December 22, 2006 I have allready had this ECU flash but it wasn't for the whining noise. I had some kind of knocking noise on start up, kind of like tapping a metal pipe 3 or 4 times. Dealer sent for the disc for the ECU and explained that this would adjust the metal flaps in the manifold on start up. I cant remember if it kept them completely closed or open on start up but it solved the problem. Link to comment Share on other sites More sharing options...
macdond Posted January 19, 2007 Report Share Posted January 19, 2007 PetrolDave Just as suspected, car went into Audi to get the ECU update. Started the car this morning and problem is still there. On the plus side I think I am getting better mpg. Just waiting on Stirling Audi to find out what they are going to do next. Considered changing the car but shocked to only get offered 22K Thats 20k depreciation in 6500 miles/2 1/2 years , by my sums that's about £3.50 a mile. It would have been cheaper for me to take a taxi everywhere, at least then I could have a drink Link to comment Share on other sites More sharing options...

macdond Posted January 22, 2007 Report Share Posted January 22, 2007 Drewcam You haven't seen how taxi drivers drive in West Lothian. My brothers Mondeo 2 Litre TDCI 130 taxi has been know to shift on occasions However you will never see this due to all the soot it chucks out the back Link to comment Share on other sites More sharing options...
