Hi
Can anyone guide me to find out how I can sort out the following problem. Had the head gasket done recently went to London all good, on the way back engine management light (EML) come on along with the traction control light & SCBS (inspection required light). Had a diagnostic carried out and got the following codes: U0401: Invalid data received from ECM/PCM. There were other codes for the Turbo, when we cleared them the U0401 is the only one coming back. Can anyone help who has knowledge about this? Does anyone have the ECU wiring diagram?
Thank you.
