Kangoo Transmission Control Unit Failure
Summary of the thread
A 2020 Renault Kangoo diesel with 200,006 km is experiencing severe gearbox issues, including non-responsive paddle shifters, gear slipping, and a grinding noise during shifts. The vehicle entered emergency mode, and diagnostic codes indicate a defective transmission control unit. The suggested solution is to replace the faulty transmission control unit, which has been confirmed by a mechanic, with an estimated cost of 1000€ for replacement and labor.

Thanks for the reply! No real warning. Just started acting up with the slipping, then BANG – emergency mode. With your Astra, what exactly was the fix and what did that end up costing you? Was it also the transmission control?

Yes, after some head-scratching from my mechanic, it turned out to be a faulty transmission control unit. Considering the symptoms you're describing and the error code you're getting, it does sound extremely similar. I would definitely recommend taking it to a reputable workshop to get it properly diagnosed. Better safe than sorry!

Thanks so much for sharing your experience! I took it to my local shop, and they confirmed the transmission control unit is toast. Quoted me about 1000€ for the replacement and labor. Ouch! At least I know what's up now thanks to your help.

Oh man, that sounds rough! I had a similar problem with my old Vauxhall Astra. Although it wasn't the paddle shifters, I experienced the same slipping and emergency mode. Was there any warning before it went into emergency mode?
