Renault Master won't start transmission error

Hi, I'm having a strange issue with my 2016 Renault Master diesel. It's got about 109,150 km on the clock. Basically, it won't start and the check engine light is on. I've also noticed the gearbox seems to be slipping and shifting really roughly. I plugged in an OBD scanner and it shows an error related to the transmission. Could this be related to a defective parking position?

I had a similar issue with my Renault Master. The symptoms you describe sound familiar. Does the error message point to a potential control unit malfunction?

Yes, the error message does seem to indicate a potential control unit malfunction. Do you think this could be the main reason that I am not able to start the engine? How did you resolve the issue on your car?

In my case, the defective control unit was indeed the culprit. It seems to affect the parking position detection, which then prevents the engine from starting as a safety measure. Considering all the symptoms you're experiencing, I'd recommend getting it checked by a qualified workshop. It could save you from further damage. For me, the repair cost was around 1000€.

Thanks for the advice! It's really helpful to know that someone else has experienced this. I'll get it booked in at the workshop ASAP. Hopefully, it's just the control unit and nothing more serious.
