Haggar

Hi I have had the same issues with my A7 coolant in the loom, I have changed the coolant valve and cleaned the connections to the gearbox.. this has cured the gearbox malfunction but I have lots more faults parking brake fault, tpms, steering etc. I can’t communicate with the Ecu, gearbox and other systems has any one else experienced this and cou it be the coolant has gone further into the loom
