Hi guys, I really need help. All of a sudden, my golf with bkd engine gave an over boost error. Each time ignition comes on, even with engine off, I get a reading of 2139mbar over boost. I changed he wiring, changed the sensor, disconnected the small connector on the ecu, disconnected all of the wires on the large ecu connector except those which stopped communication with vcds and even changed ecu, and this error persists. Can someone please help me as I am about to send car to the breakers, and I just bought it.
