Hello,

I had a problem with ASR/ABS not working. Got the car diagnosed and found out I had a faulty Brake Light Switch. Got that replaced and everything worked fine for a couple of days...

Today, the high pressure pump won't shut off - even when the car is off ! -
Had to disconnect the wires.

I get too error codes:

C1401 High Pressure Return Pump Circuit Open/Shorted; Will Not Shut Off.
C1305 RR Solenoid Hold Pressure.

Checked all the wires and unplugged them from the control unit but the pump just stays on and ASR/ABS are not working.

What could be wrong now??? Pump Relay? Control Unit?

HELP!

Thanks

Can anybody tell me what to check. I tried everything I know.

HELP!

probably a stuck relay try banging on it.

I hope so. That would be the best solution

Any idea where the relay is? Is it inside the fuse box or in the hydraulic unit itself?
