Sedici Sporadic Error Messages

I had a similar experience with my Opel Astra a few years back. The symptoms sound eerily familiar. While the cars are obviously different, the underlying electronics might share some similarities. In my case, the issue stemmed from a faulty CAN bus connection. Have you checked the wiring harness for any signs of damage or corrosion? Also, were there any specific error codes that the OBD-II scanner reported? Knowing the error code might give you a more specific direction.

Thanks for the reply! I appreciate the info about your Astra. Regarding the wiring harness, I did a quick visual inspection, but I didn't notice anything obvious like frayed wires or corrosion. The OBD-II scanner spat out a few codes, but they were all fairly generic related to 'system voltage low' and 'communication bus error'. Nothing specific to one particular module. I'm wondering if you remember any of the specific error codes you received when you had the issue with your Opel?

I understand. Unfortunately, I don't recall the exact error codes from my Opel. It was a while ago. However, given the generic codes you're seeing and the symptoms you described, it does sound like a CAN bus issue or potentially a control unit with a bad connection. I would advise visiting a qualified workshop before things get worse. They will be able to properly diagnose it and estimate the eventual repair cost.

Thanks, I appreciate your advice. I'll take your advice and bring it to a workshop to get properly diagnosed.
