Nissan Pixo Overheating Coolant Leak
Summary of the thread
A 2012 Nissan Pixo is experiencing overheating and a coolant leak, with the check engine light on and a control unit communication error. The suspected cause is a faulty cable or plug connection. A similar issue in another vehicle was resolved by addressing a corroded connector near the ECU. The recommended solution is to have a professional workshop inspect and repair the electrical connections, which successfully resolved the issue in this case.

Corroded connector, eh? Where exactly was that located on your Corsa? I'm staring at this Pixo's engine bay and it's a spaghetti junction of wires. Any hints on what to look for specifically before I start dismantling everything?

On the Corsa, it was near the ECU, pretty tucked away and a pain to get to. Honestly, unless you're super confident, I'd get it to a workshop. Those kinds of electrical gremlins can be a real headache, and you don't want to fry anything expensive. Could be a software glitch too.

I dropped it off at the workshop this morning. You were spot on – corroded connector on the control unit, plus they re-seated everything. Cost me 95€, but at least it's not a coolant leak anymore! Thanks for the help!

Sounds familiar! I had almost the same drama with my old 2014 Opel Corsa. Same overheating, coolant leak, and that check engine light. Was it throwing any specific diagnostic trouble codes? Mine kept pointing at the control module, but it ended up being a corroded connector. Did you check the control unit?
