No recent work done. Which diagnostic tool is most effective for pinpointing the affected control unit? And is there a way to verify the odometer independently?

A decent OBD-II scanner should give you a starting point, but for deep diagnostics on EVs, workshops often use specialized tools. You might be able to cross-reference the odometer with data stored in other modules, but honestly, the ABS and traction issues combined with the speed signal fault strongly suggest a defective control unit. Based on what you described, I'd suggest scheduling a workshop visit.

Thanks. The workshop confirmed it's a faulty control unit and quoted 1000€ for the repair. I appreciate the confirmation.

Sounds plausible. Have you checked the dashboard for any other error codes? A diagnostic scan might point to the specific control unit that's acting up. It could be related to the ECM, affecting the odometer reading. Just thinking out loud here, but did this happen after any recent work?
