The car had a new PAS pump fitted just before I bought it, and I assumed they had either used the wrong fluid or not bled the system properly, so I drained it off, refilled it with the proper VAG stuff & bled it. It's no better.
It's bad after a run (i.e. when it's hot)... but it's not leaking fluid (the fluid level isn't dropping).
The serpentine belt isn't slipping - at least I can't hear it slipping
Help!
