01435 brake pressure sensor 1 g201 problem in electrical circuit

[Sammerchant]

Hi guys !! Help needed here - I had abs and esp light on - mot station said I need to change the abs pump - I got a second hand one and changed it ( changed my abs ecu from old pump) .. the problem I have now is with the snap on machine it says module incorrectly coded and can’t code the new abs pump .... this might have nothing to do with it but I noticed a lot of water sitting in the battery compartment (drained now)
I am based in Leicester and am willing to travel if anybody can fix this issue for me

If this is a PQ35 platform (Golf 5, A3 8P, Octavia 2 etc) you can get a repair kit from VW under the part number 1K0 698 517 B for £303.55. It has be be installed very carefully and the system must be force pressure bleed in basic settings mode after installation.
