Avantime automatic transmission fault

Hi, I'm having a problem with my 2003 Renault Avantime diesel. It has done 142441 km. Lately it won't start sometimes. The check engine light is on, and the gearbox slips when it does run. I scanned the error memory and it shows a fault related to the automatic transmission parking position. Any ideas?

Sounds familiar. I had similar issues with my Avantime. Does it feel like the shift lock is engaged even when it shouldn't be? Because that can stop the starter from engaging. Does it shift cleanly into neutral? A defective control unit could cause this.

Yes, it does feel like the shift lock is engaged. Shifting into neutral is rough sometimes, other times it feels fine. Is the control unit difficult to replace? Where is it located?

Okay, so it sounds like you have the same problem I had. I wouldn't attempt replacing the control unit yourself unless you're very experienced. The control unit needs to be coded to the car. The risk of damaging something is high. I would take it to a workshop, even though it's going to be costly.

Thanks for the advice. It was indeed a defective control unit. Cost me around 1000€ to get it sorted at the workshop, including coding.
