Theres a couple of guides on how to do it on t'internet, but one involves opening up the system and pumping it all out....the other involves a lot of PAS fluid and is a lot less hassle.
Sealed for life my arse....This is the colour of mine before i changed it...


Get yourself a syringe with a bit of tube on the end. Or a baster.
Suck out all the fluid in the reservoir and replace with new stuff. Start the engine and turn the steering from left to right 5 times.
Repeat until the old oil looks like the stuff youre putting in. Job done.
Like i said, you'll need a bit more oil but its less aggro than replacing copper washers...:D

Good man Egon, using the syringe method :thumbsup. I wouldn't want to use the pump out method for fear of introducing air in the system. No where to bleed either.

Bleeding is simple, just turn the steering wheel from lock to lock a couple of times and it all comes out through the reservoir. I've changed fluid a few times on my BMs and although it's looked nicer when changed it never made any real diference to the steering. Only time I had a problem with lack of assistance it was a seal gone inside the rack and I fitted a recon rack.

yeah, i've heard that theyre pretty self bleeding, but i wouldnt want to find an airbubble half way round a corner! Mine went really stiff for a few turns after i changed the rack and had to fill from scratch. took a couple of days till it felt happy again. :)

Your running 35 up front! Im on 32 due to the stretched tyres... should be 28 should it not?
any thing lower than 35 in my fronts ben and i would need arms like popeye to turn the wheel mate 28 and my tyres would be flat


cheers for the replies tho guys :thumbsup:thumbsup

What mileage or date is specified by BMW on the service schedule? Just out of interest...

My tyre pressures (according to the sticker/manual) are 36psi front, and a mahoosive 42 in the rears!

Back on track, heavy power steering can be a sign of a failing pump, or a sticky valve in the rack. You may get lucky with just a fluid change though. My local BP sells the correct Dextron 3 fluid for about £10 - maybe yours does too. Changing the fluid is easy enough, maybe an hours work if you really take your time. A rack change is no more than 2 hours, and the pump can be done in about an hour too (from underneath is easiest). There are lots of different pumps, so if you do conclude that yours is knackered, make sure you source the appropriate replacement.
