Kangoo engine control unit communication error
Summary of the thread
A 2013 Renault Kangoo diesel is experiencing an engine control unit communication error, leading to a check engine light and engine overheating. The issue is suspected to be due to a faulty cable or plug connection, as indicated by coolant leakage and excessive pressure. The problem is intermittent, and a similar case was resolved by diagnosing a communication fault through the data link connector at a workshop. The solution involved confirming and fixing a defective connection.

It's pretty intermittent, yeah. Sometimes it's fine for a day or two, then bam, it's back. When it happens, the overheating is almost immediate. Any idea what the damage was?

Yeah, mine was intermittent too. It ended up being a fault that the workshop was able to easily diagnose with the data link connector, the control unit had a communication fault. I ended up just taking it to the shop to sort out.

Cheers! That's helpful. Took it to the workshop who confirmed a defective connection. They charged me 95€, all in. Thanks for the help!

Sounds rough. I had something similar with my Kangoo. Was it consistently happening, or just intermittently?
