Urgent M271 ESP/ME ECU Faults and Limp Mode after Engine Replacemnt
Took to an indy where they checked and cleared codes after that ESP issue and limp mode is occurring constantly...
Engine was a non-start with fan running continuously (researched failsafe) and scan tool wouldn't recognise ME ECU... disconnected battery, checked ECU connections, engine restarted ....
next day problem re-occurred
...replaced vehicle battery ...still no joy When I have been able to connect to ME ECU (sporadically after battery reconnect) have got this code P203B-2 and ECU internal failure relating to P0606
This seems strange as nothing really has changed and the ECU was only removed refitted with airbox during engine replacement - so really don't see why this would have **** itself also???....
Any assistance guidance would be greatly received - ps. I have read most of the associated threads to no avail.
