Mine was doing that in cold weather and the fluid level was below the Min mark. _____________________________ 2002 A6 three.oh (in reply to beefski) Post #: 2

Flushed it and found a bad hose clamp that was causing a slow leak. Once I replaced the clamp and had the correct amount of fluid...no more whine. _____________________________ '98 A4 Avant Quattro 2.8 V6 30v Stock Dented roof Scratches Non-functioning sunroof Non-functioning cruise control Flaky LCD (in reply to beefski) Post #: 4

But why would the noise go away after warming up? This just started with a few cold days here. (in reply to jukeit) Post #: 5

Check your owner's manual if for some reason you don't find it. It will tell you right where it's at. Not sure why the noise goes away once it's warm. _____________________________ '98 A4 Avant Quattro 2.8 V6 30v Stock Dented roof Scratches Non-functioning sunroof Non-functioning cruise control Flaky LCD (in reply to beefski) Post #: 6

RE: Noise upon cold start - 11/21/2005 12:33:08 PM    jukeit Posts: 305 Joined: 4/14/2005 Status: offline It contains something called Petosin or Pentosin. Can't remember for sure. I bought it from the dealer for about 25 bucks per liter. _____________________________ '98 A4 Avant Quattro 2.8 V6 30v Stock Dented roof Scratches Non-functioning sunroof Non-functioning cruise control Flaky LCD (in reply to beefski) Post #: 8

Correct me if I'm wrong, I think VW supplies the same on its cars. So maybe a VW dealer will give you a better price? (in reply to jukeit) Post #: 9

RE: Noise upon cold start - 11/21/2005 7:37:59 PM    kianoosh   Posts: 84 Joined: 6/29/2005 Status: offline Jukeit, I notice you have a non-functional sunroof. Do you want it fixed? Mine was not working (I own a 97A6) and during the process of fixing it, I almost found all the components for much less than the dealer. I never bought any since it just turned out to be a misplaced fuse! Just figured I'd ask, Kianoosh (in reply to kianoosh) Post #: 10

RE: Noise upon cold start - 11/22/2005 12:26:04 PM    jukeit Posts: 305 Joined: 4/14/2005 Status: offline Hey Kianoosh, just PM'd you concerning the sunroof. Beefski, I thought my problem was a belt too, but the noise cleared when I brought the power steering fluid level within spec. Have you checked your level yet? _____________________________ '98 A4 Avant Quattro 2.8 V6 30v Stock Dented roof Scratches Non-functioning sunroof Non-functioning cruise control Flaky LCD (in reply to beefski) Post #: 13

Its on the lower passenger side of the engine compartment. It only runs for a short time after startup and then goes off when the car is warmed up. (in reply to beefski) Post #: 15

RE: Noise upon cold start - 11/25/2005 1:25:36 PM    techbod Posts: 12831 Joined: 11/4/2005 Status: offline not really that bad as long as engine runs ok, when its bad the ECU goes into limp home mode to protect the engine and electronics, a get you home thing (in reply to beefski) Post #: 19
