please help me with my car. It was running fine then it cut out and since then no crank. I have changed battery and the module and the under bonnet fuse box The inside of the BSI has no visable damage. I have 2 codes 0528 absence of starter command.. and 056b which says Fault supply protection and management unit lack of coherence between the status of the key and the status of the main supply relay following the switching off of the ignition.......Whatever ever the hell that means??? I would be so gratefull for any help

Have you checked the starter motor fuse? Or the solenoid? This seems to suggest that those might be faulty:

Good luck with that but thinking aloud you could easily have software issues one of the worst problems on modern cars occurs when they have the power interrupted as in intermittent on/off disruption this can spike your ECU BSI which means they could corrupt themselves damaging the software you will lose the coms on the electrical systems as in damage to the CANbus meaning you could lose some or all functionality between Computers ?

Yes I think it spiked as I was doing some voltage testing on the coils at the time. An ecu kit will cure everything, am I right??

Isn’t the stereo linked/coded to the BSI? I seem to remember reading that somewhere.
Other things to keep in mind, there is potentially going to be mileage discrepancy and the VIN on the ECU won’t match the vehicle VIN. You’ve not mentioned the keys but I’m assuming they are part of the ECU kit.
