Alright, this is what i have done and what i have got.
Connected the gage as per the shop manual on a totally cold car.
Disconnected the plug (greenish) behind the air-filter.
1989 930.
started the pumps: Valve closed 6.5 bar?
Valve open 2.7 bar?
Its 24 degrees
See below for bleed off times
Does any of this sound right? I have never messed with the WUR,why the change ?
