It doesn't matter to the pressure pump whether it's 4 wheel TC or 2 wheel TC. It just supplies the pressure. Either the relay is knackered or the pressure switch is knackered simple as that. Nothing to do with ECU.

Cheers wammers glad I listened to you
P.S mine is 4 wheel tc not 2 wheel as in my post, but what the hell new pump on when this blooming rain stops
 
Yep that be the four wheel traction control one then, they do seam to be the only ones that pack up:rolleyes:

They definitely seem to have more issues with ABS all round. Especially considering it was only fitted for 3 years or so.
 
All sorted as @wammers said pressure switch in pump. Changed unit bled brakes been for a spin no warnings and pump turning off. I glad he's on our side. Well what's next
 
Summer was late arriving and brief, still lighting the fire at the start of June, now it's like late autumn with the temperature down to 9C a few nights ago. Just bought 6 cubic metres of logs, looks like we will be needing them soon:(
9 degrees that's bliss for up here:p T-shirts and shorts weather:cool:

Check how often the pump comes on, it should only run ever 4th or 5th press of the brake pedal. If it operates more often the accumulator needs replacement before you wear out the new pressure switch.
