Arkana Overheating and Coolant Leak

I've got a 2021 Renault Arkana hybrid with 225778 km. The engine's overheating, the check engine light is on, and there's coolant leaking. Could a defective cable or plug connection be the issue?

Hey, that sounds familiar! I have a Renault Arkana too, and I had a similar scare last year. Was it a control unit communication error showing up when you ran diagnostics? It caused all sorts of weirdness.

Yeah, it was! A control unit communication error. The diagnostics pointed to that. What did you end up doing about it?

Yep, sounds like the same thing. I spent ages looking for the diagnostic trouble code and all that. In the end, it turned out to be a wiring issue causing the communication fault. Honestly, save yourself the headache and get it to a workshop. They'll sort the wiring properly.

Thanks! I appreciate the advice. Took it to the shop, and you were spot on – a defective cable or plug connection was the issue, causing the communication fault. Cost me 95€ to get it sorted.
