Ok, I have a 2001 Audi A6 2.8L ... The car is making a high pitch noise coming from the engine compartment. Someone told me it seems to be the Powersteering pump..the noise pitch does change when I turn the wheel... This thing is driving me insane... Anyone has any thoughts??? Is there any way to test the powersteering pump or disable it to rule it out? I guess it would be difficult since you would have to remove the belt....

PLEASE ..ANYONE!!??

check the pwr steering fluid level.

57 views and one reply??? Anyone else pls??

low fluid level - power steering pump - power steering belt too loose or worn

I am having a high pitch noise on cold starts near the back of the engine compartment, and it sounds like it's the air pump. Where is your sound coming from in the engine??

I had the noise and had to replace the pump. Not to hard to do either. Pumps are about $100 used. I picked one up with 20K miles and it has been great. If it isn't that, I had a weird noise and it was the alternator failing.

where did u get the used pump for 100 bucks?
