power steering fluid - 7 series (new shape)

[mr_tony]

Chaps,

Any recommendations on what to put in the power steering reservoir on a 7 series?
Occasionally I get a warning flash up saying steering oil low - ususally after going rather quickly round a tight corner / roundabout. Figure this means the reservoir is a little low and needs a top up.

Don't really want to go to a dealer to do this (unless y'all think its wise) - so whats the part number for power steering fluid - or where can you get this for bimmers at reasonable rates?

pentosin chf 11s

You probably want to have it check for fluid leaks

Mine had dextron III in it.......... is there a date range of fluid types Blackspider?

on the resevoir cap or pot should be the fluid type stamp...most will be chf 11s.

Thanks guys, that should be enough info for me to sort it.
Only happens when I really nail a tight hairpin, so it could just be the fluid sloshing about in the reservoir and tripping the sensor - still a little top up won't hurt.

Don't seem to be any leaks in the system - certainly no tell tale drips under the car...

Mine just says ATF fluid only (surely that covers a huge range of potential types!!)

The stuff in it is red but it's had a leak in the past so been topped up on a regular basis til I got the car and fixed the leak

Yours is as you have been using is ATF 220 or dextron 3,this seems to be used on the smaller engine 7 and the CHF 11 S on the V8 and up-also if the car has dynamic drive(active roll bar)then it will only use CHF 11 S

How weird it's a 4.4 V8

but thanks for the clarification I'll stop worrying now
