Avantime Service Required Message and System Errors

Whoa, that sounds familiar! I had almost the exact same symptoms – weird error messages, systems cutting out – with my old Peugeot 407. Audio, navigation, the whole shebang would go haywire! Could it be the cable? I sure hope not... Was a pain to figure out on my car.

How did you resolve the problem with your Peugeot 407? Or at least, how did you figure out what was causing it? Was it a cable connection issue, or something else?

Well, I never actually fixed it myself! After chasing ghosts for weeks, I bit the bullet and took it to a workshop. They ran a full diagnostic and traced it back to a faulty connection in the control module. They re-terminated some connectors and the car was happy again. It ended up costing me about 150€. I'd say a visit to the mechanic is worth it. You could try chasing the error yourself, but it's just not fun.

Thanks for the response! It seems a workshop visit will be beneficial. It seems likely the issue is within the cable connection of the control unit, like you and the mechanic suspected. I’ll tell the mechanic to inspect for damaged cable connection of the control unit, repair the faulty connection and replace damaged cables. The estimated repair cost is 155€.
