I have a 2003 A6 twin turbo 2.7 quattro. The brakes frequently squeal/squeak while stopping. The front and rear brakes have both been replaced under warranty and I am being told by the Audi service department that the squeak/squeal is normal for this type of vehicle. They also claim it is normal during cold and/or wet climate operation. It does not happen 100% of the time;however, frequently enough to be extremely annoying. I cannot imagine driving this car like this. Does the service managers response make sense?

need to be cleaned. Then apply a strip of aluminum stick-on anti-squeel shim (NAPA) onto the back of the outboard pad. Apply a thin layer of caliper lube to the contact areas on the backs of both pads, then reassemble. Also ensure the caliper carrier pins/bushings are well greased. The pads often wear such that the inner pad in particular, developes a taper. Replacing the rubber caliper carrier pin bushings with bronze parts will prevent this from occuring. The shims and caliper lube usually stops the noise. Performing the pad break-in bedding procedure is required also.

Think about it. How many cars would Audi sell if everyone who took one on a test drive heard "squeeeeeeeek" when they rolled up to a stoplight?

Possible things to try:

Re-bed pads
Apply disc brake quiet to back of pads
Grease all the sliding parts
File down/chamfer the leading/trailing edges of the pads (I would do the others first)
