Hallo.
I am sorry but I dont speak German-I am learning. I know that most people in Germany speak English.

I have a late 91 850Ci (ASC+T) LHD from Germany.

Can someone help me with some advice. I had a leak in a hose (power steering pipe which goes from cannister to first part of booster). I replaced it filled her up with correct 11S pentosin and now when I started her up she was leaking faster from underneath the pressure regulator which is situated next to the shock tower on a bracket right next to the battery -ve charge terminal.

The leak is very big and not from any of the pressure sensors or where any of the pipes go into but from the body itself i.e. underneath the pressure regulator.

Do I need a new regulator?
Can I get it repaired?
Will a 7 or 5 seies one fit?

IS THERE A SPECIFIC PROCEDURE TO INSTALL NEW ONE?
Any help would be greatly appreceiated.

best wishes
