I am making progress on the ABS ECU issue and in addition to the ECU repair company in Germany I am also in conversation with Bosch Germany, both say they can repair 5.3 ABS ECU's at a very reasonable price but require the exact Bosch part number and fault codes, I cannot see a label on mine, does anyone have the part number ?
Also they require the exact ECU fault codes, I did take mine into a specialist last week to have the codes read but the Maserati technician was out on a call, they did read the codes but could not tell me what the issue was and needed to get advice from the other tech. I have chased them up but am getting no response. Can any garage with a good diagnostic tool read and understand the codes, it is a 2002 model with the later diagnostics port.
