Expert ECU Programming Issue

My 2021 Peugeot Expert diesel with 297410 km is having electrical issues. Error memory shows a general electrical malfunction and the navigation is dead. Diagnostics say the control unit programming is implausible. Anyone seen similar ECU problems?

Interesting. What error codes are you seeing for 'implausible programming'? Has the van had any recent electrical work or control module reflashes? That might help narrow it down. A software reset could fix it, but we need to know why the programming got corrupted.

The report says general ECU config fault, but the error code isn't very helpful. No recent work that I know of. What could cause the ECU programming to become implausible like this?

Corrupted ECU programming can happen a few ways: manufacturing defect, power surge, or even interference. It's not common for it to just happen. The dead navigation points to a central control module issue. Without a specific error code, I'd suggest a workshop visit for a software reset.

Understood. Thanks. I'll book a workshop visit for a diagnostic check and software reset. Repair is estimated at 240€.
