My power steering fluid is leaking. Have anyone experienced this? Where do I start looking? I cant seem to find the leak? Any ideas?

 

Much of the time it starts to leak right where the rubber hose meets the reservoir. It's always possible it may be leaking at the rack though.

Remember when topping up - Audi's require specific mineral oil based fluid (pentosin chf 11s), not your usual variety.

 

Where exactly is the power steering rack?

 

Not somewhere you can look without a lot of work. When the rack does leak it is usally one of the hoses that squirt a small amount of fluid when you engage the steering. There are several hoses, but one does travel the length of the engine block on top. There are others that run under the engine. Do you notice a small pool of oil on the engine block at all?

Do you see fluid on the ground after being parked for a while? This could mean a leaking PS pump.
