Mokka Fault Memory Lock Active

I had similar gremlins in my Mokka. Is the error related to a specific control unit? Could be a computer system glitch causing it. I had issues with random fault codes popping up due to low voltage during cold starts. Check your battery and alternator, just in case.

Yeah, the error code points to the main ECU. Did your error message also mention the memory lock?

It did, actually. The memory lock thing cropped up alongside a bunch of other seemingly unrelated errors. Ended up being a power issue corrupting the data in the ECU's memory. Bit beyond my skillset, so I took it to a workshop. They reflashed the ECU and sorted out the underlying voltage problem.

Right, sounds like the same deal. Dropped it at the garage, they quoted 240€ for investigation and repair (presumably a reflash as you mentioned).
