Hey there, new member here. Been driving VW's and on VWVortex forever but just got a C5 A6Q and really like it a lot. We bought it because we sold our 08 Expedition EL and needed something that was affordable with the cash left from the sale of the prior veh. and could haul 2 kids. I love the Quattro and the car as a whole is great but I have a couple problems. There is a belt squealing noise when turning right and driving straight. It may not be a belt but it sure sounds like one. I know I need to replace the control arms and was thinking that maybe there is some binding causing resistance against the power steering pump. Could this be possible. Any input would be well appreciated.

 

1. Tighten the belt
2. check the PS fluid Make sure you the correct type for your car

 

1. The belt has a tensioner which colud be bad, but then you would have more problems than this.
2. Overfill the PS reservoir slightly. Make sure to use the correct type of PS fluid or you will blow the seals on your PS rack! But, low PS fluid usually gives you a groan, not a squeal.

turns out it's the AC compressor causing the belt to squeal. if i turn off the climate control, the noise is gone. it still only happens when turning right. that's okay, i knew the compressor made a lot of noise when i bought it and the dealer is putting a new one in along with a belt. problem solved.
