My highly trusted local Audi mechanic said a new pump may buzz as well. If
you have 243k on the car with no record of a pump change it may be time
anyway but do not do it just for the noise.
If you have knock sensors they are likely the culprit. At least on 20 valve
NA engines they go out a lot and will cause intermiitent massive power loss.
