Peugeot 106 Stuck in Park Control Unit?

Hi, I'm having a strange issue with my 2002 Peugeot 106 diesel, about 140k km on the clock. It seems to be stuck in park – or at least, the car thinks it is. The engine won't start, the check engine light is on, and the gearbox is slipping and shifting really roughly when I manage to get it moving. I scanned it and there's an error stored, but my generic OBD2 reader isn't giving me much detail. Could it be the gear shifter or shift lock? I've checked the gear linkage, and it seems fine. Any ideas?

A 2002 Peugeot 106 diesel is experiencing issues where it seems stuck in park, with the engine not starting, a check engine light on, and rough shifting. The problem may be related to the gear shifter or shift lock, but the gear linkage appears fine. A similar case suggested that the control unit might be faulty, which was confirmed by a garage, leading to a repair involving a new control unit.

I had something similar happen with my 106. Does it feel like it's not fully engaging in park or neutral? Mine was throwing all sorts of errors and acting like it was still in gear even when it wasn't. Was difficult to start sometimes.

Thanks for the quick reply! Yes, that's exactly how it feels. It's as if the car isn't recognizing that it's in park or neutral. Do you remember what the fix was for yours? Was it a big job?

It sounds like the same problem. I'm no mechanic, but based on your description and my experience, I'd recommend taking it to a workshop. They can properly diagnose the error and confirm if the control unit is faulty. Unfortunately, that was the issue with mine.

Thanks for the advice! I took it to a garage, and you were spot on. The control unit was indeed defective. The repair, including a new unit and labor, came to around 1000€. Appreciate your help in narrowing down the issue!
