Hi Folks,

Is your SLS pump is leaking, do you want to keep your car origional. This is for the trunk mounted unit.
The pump is still available from BMW # 37121128247 for $1,225.55 + shipping.

Here is my latest repair kit. For the following models.

it would be good, if you can provide a seal kit for the regulating valve on the rear axle for SLS. In 2008 I made some pice when we disassembled it

From the technical description of this valve made by the German company BARMAG, Model no. stamped in is VO011 34-1 or 84-1 (??)(difficult to see, although I used a steel brush):

the minimum pressure valve is to keep the system pressure behind the valve not lower than p = 30 bar.
The over pressure valve is limited to maximum p = 130 bar and opens then.
Power steering pump pressure is 130-135 bar, the dual power steering pump feeds the LAD system.
Pressure inside the regulating valve?
