Terra electrical malfunctions

Interesting. I have a Terra too, and while not exactly the same, your description rings a bell. My issue involved the onboard diagnostics throwing a code and some odd electrical behavior, though my navigation still worked. Have you checked the control module for any obvious signs of damage or loose connections?

Thanks for the input. I haven't physically checked the module yet, but the error code points to a programming issue. Could it be something that requires a recalibration or even a full software refresh?

Okay, a programming issue definitely sounds like it could be the culprit. In my case, the workshop folks mentioned something about the vehicle software needing a refresh because the programming of the control unit was implausible. Given your symptoms, especially with the navigation system being down, I would suggest taking it to a trusted workshop. My repair cost about 240€, but it might vary depending on the extent of the damage. Hope this helps, and good luck!

Appreciate the info. Sounds like a trip to the workshop is unavoidable. Will advise once I get it sorted. Cheers!
