Have got a bit further with this i had access to the AS/ESP pump and ecu i took the plug to the ecu off and water poured out what are your thoughts on if i dry the plug and the pins it goes onto and plug it back in is there a chance it could work again with no faults.
Thank You Stephen.

If there's no corrosion there's a good chance, but only one way to find out!

[Looneytunes]

Thank You for your reply there is no corrosion so fingers crossed will let you know how i get on.

Did you find the problem?
I’m currently diagnosing a C1302 and from what I’ve learnt and your symptoms you still have an issue with the plug on the ABS pump/ESP ECU.
The plug on there has wires connecting it to the BSI

[GiveMeABreak]

It's connected to a lot more than the BSI.... It's a multiplexed CAN vehicle and the ESP system connects to both the BSI, the Engine ECU, engine fuse box and other sensors and systems.
