My A6 2.7t has been making a droning noise at speed. It is a subtle noise coming from the engine... similar to a noise from a wheel bearing that is starting to go bad or a bad tire.... but in this case is definitely coming from the engine.
I don't have any oil burn or power loss and my turbos seem to sound normal (the little high pitched whistle).
I only hear it under load but it is fairly independent of speed/gear etc.
Any ideas would be appreciated.
