Corsa stuck in transport mode

Sounds familiar. My old Renault Megane had similar issues a few years back: electrical gremlins everywhere, nothing worked right. Could be transport mode. Are you sure the car doesn't still think it's new?

How did the transport mode issue show itself on the Megane? Did you use any diagnostics to confirm it, and how did you fix it?

It was a while ago, but the symptoms were spot on. I couldn't figure it out myself. I took it to a workshop, and they sorted it out pretty quick. Transport mode can be a real pain.

A workshop visit was the right call. They did a simple reset via the diagnostic port to disable transport mode. Cost 0€, thankfully. Thanks for the help.
