Lots of squeaking when the fan is turned on, varies with fan RPM.
Sounds like a worn out bearing/bushing on the fan motor. How tough is
this to access and lube or replace? I did this once on a Volvo 240 and
I swear those Swedes built the entire car around the fan motor. It
took MANY hours. Hopefully it isnt such a big job an the A6. Any
