Power Steering Pump was making whining mechanical noise
My A5 developed a steering shimmy at ~5K miles. The Audi dealership failed to fix the problem with a road force tire balance at a previous visit. This time they replaced the tires and installed revised control arms with stiffer bushings
Lower front control arm ball joints developed squeaking sound when suspension was under load, such as going over a bump or turning a hard corner while parking. Parts were non-serviceable and were replaced under warranty with updated parts.
