I have a second-hand 2003 Audi A4 Quattro 3.0L. It's making squeaking noise when steering at low speed (parking for example).

I later noticed that the level of power steering fluid is kinda low. However, I have no idea what power steering fluid to use. I asked a guy in a local Autozone, he didn't know either.

Could anybody give me some advices? Thanks!

 

Go to the dealer....It's some kind of mineral oil for the a4... they dident have it at any local auto stores.

 

Dealer.. $17 a quart [:@]

 

mine is second-hand 2002 A4 3.0 Q, too.

I have the same issue as you do.

are you sure itz cuz our fluid'z low?

 

when turning the wheel all the way to full lock and your fluid is low, you usually hear this whine. You should top it up to 10mm past the max line with power steering fluid from the dealer or pentosin chf 11s ONLY.... Do not use anything else.

 

when i put on my new PS cooler, that damn thing whined and groaned for 10 minutes, lock to lock... had me so nervous.......

 

10mm past max line?!

This is what a dealer told me:

Checking power steering fluid level when cold:
[ul][*]move front wheels in straight-ahead position[*]fluid level must be in area of MIN mark (up to 2 mm above or below mark).[/ul]

Checking power steering fluid level when warm:
[ul][*]bring front wheels to straight position[*]fluid level must be between MIN and MAX markings[/ul]

 

What I learnt from this forum is that,the reasons of squeaking at low speedcould be any of the following:
[ul][*]power steering fluid level is low. $17[*]bush bearing needs lubricate. $20~[*]tie rods need to be replaced.$500~[/ul]

 

you're acting like 10mm is alot. go get a ruler and see how much 2mm is and then 10mm... If i didnt know what i was saying i wouldnt offered any opinion. if you dont have a ruller with mm, 1cm = 10mm.

 

1CM is still a good bit.. as long as its above the min line when warm, it wouldnt bother me at all
