Hey Folks.

I've noticed occasionally now for a few months of a 'whine/grumble' from what I think is the PAS. Hard cornering and it'll start to make a strange noise. This will last for maybe a minute even once straightened out, then stop. Starting again maybe a few corners later.

Any hints?

Thanks!

Low PAS fluid

Yorkshire's right - this sounds just like the problem I've had on my C220 CDI - low PAS fluid - it's a quick job to top up - just check the dipstick in the reservoir - but don't overfill - you'd be surprised at how little you have to add.

Oh, and make sure you get the right fluid for your car.

Now, if I could only work out where it's going!

Air in the System?

I had this problem on a Volvo V70 a few years ago - a "groaning" in the PAS which got worse and worse. PAS reservoir was full of "mayonnaise" ie aerated fluid. In this case, leak turned out to be from a crack in the fluid reservoir, but could be in pump, rack or connecting pipes.
