I keep getting this power steering noise problem when the temperature gets around 30 degrees. It buzzes, and when I reach the farthest left or right turn of the steering wheel it begins to chatters.

I've check the power steering fluid and it is topped off and clean - it's been that way forever. The only thing I can think of is that it may have some water or something in the lines and then it either freezes or thickens to the point where it restricts the flow of fluid.

At least until it gets warm again. I don't know. Anyone ever hear about this?

 

I have never heard anything similar to that, however. I would consider having your steering rack checked though. Maybe a complete flush of your Power steering fluid as well.

 

You may have a idea with the flush - it is an older A6 (2001 A6 Quattro with 107K). Thanks a million for the quick reply.

 

The low pressure hose right off the pump will suck air & make all sorts of noise. replace hose & both clamps If you look at the fluid after turning the wheel it will probably have bubbles.

 

This is also a good idea, my friend has a b5a6 also. Working on his inspired me to buy my s4.
