Jumper ECU error Main Relay

I had a similar issue with my Jumper. Error stored in the error memory, and performance was definitely affected. Was your error also pointing towards the ECU?

Yes, the error definitely pointed to the ECU. So, was the relay the root cause for you too?

Indeed, that was the issue. If the error message is the same, I would recommend you to go to the workshop. In my case, they measured the relay, found it defective and replaced it.

Thanks for confirming. Ended up being the main relay as suspected. ECU repair cost 120€. Appreciate the help!
