GrandlandX Hybrid ECU Error

I'm experiencing a problem with my 2022 Vauxhall GrandlandX hybrid. It has 116612 km. The engine control unit seems to be defective. Symptoms are reduced engine power, and an error is stored in the error memory. I suspect the main relay.

A 2022 Vauxhall GrandlandX hybrid with 116,612 km is experiencing reduced engine power and an error stored in the engine control unit (ECU). The suspected cause is a defective main relay, which is a common issue with these vehicles. After checking the error memory and consulting with another owner who had similar issues, it was confirmed that the main relay was indeed the problem, and the repair was straightforward.

I also own a GrandlandX hybrid. I had similar issues, although my mileage was lower. Have you checked the fault codes? It could be a number of things, but relay problems are quite common on these.

Thanks for your reply. Yes, I checked the error memory, and it points towards the engine control unit. Do you remember what the eventual repair was in your case? I'm trying to get an idea of what I'm in for.

Yes, mine was the main relay too, which caused the ECU to throw errors. I'd suggest getting it checked at a workshop to confirm. It should be a pretty straightforward fix, though.

Thanks. I had it checked, and it was indeed the main relay. Repair cost 120€. Appreciate the help.
