[928uk] PSD question

[James Musson]

Thanks for the reply. So far, the warning has only come on when the unit should actually be doing something, i.e. when the rear wheels are slipping and the green PSD light is on. Unfortunately, I don't have anything to read the fault codes with :-(

>From what you are saying, though, it sounds like the system will protect itself from further damage so there's no need to pull the fuse? The reason I asked was because there are stories around of the pump motor coils burning out and I would like to avoid that if it hasn't already happened.

Thanks

James

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.
