[928uk] PSD question

[Paul R Smith]

If the system detects a fault it will shut down, so the pump should not 
run continuously.
It is located in the left rear wheel arch, behind the left rear wheel. 
Have a listen around there when the ignition is turned on. If the pump 
runs for a while then turns off, see when the warning comes on, that 
might give a clue, e.g. if it fails to achieve pressure, recognises a 
fault, shuts off the pump and brings up the warning.
But, I would strongly advise you to read out the fault codes before 
diving in and flushing it.

There's quite a lot of info on the 'net about this condition and I am (perhaps foolishly) hoping that the system just needs flushing, given that I can see any record of that being done in the recent service history. I don't have time to do that, or get someone else to, right now but I wanted to drive the car to Brooklands on New Year's Day.
