BMW 730D (Bosch: 0281 013 500 / DDE 7 803 369) ECU Repaired

A customer in Bolton, Manchester sent an ECU in for a BMW 730D. He advised that it was having intermittent starting issues. After the initial test, no faults were discovered however on an extensive soak test the ecu did trigger faults and we were able to locate the issue with the main processor which was unfortunately irreparable. The customer was offered a replacement unit and we were able to transfer the coding from the old unit into the new one therefore no programming was required on the vehicle.

We were sent this ECU for a 2006 Ford Focus 1.6 TDCI from a garage in Leeds, West Yorkshire, regarding issues with intermittent starting and sometimes no connection with the ECU via diagnostic equipment. After completing a full ECU Test, we were able to advise them that the unit was faulty and could be repaired.

We received this ECU from a garage in Colwyn Bay, Conwy that reported the vehicle came in to them as a non-starter and they were unable to communicate with the ECU via the OBDII diagnostics port. The garage did check the wiring and possible fuse/relay issues and it all pointed back to it being a faulty ECU and so sent it in for testing.
