Interesting thanks.

Keith, I am pleased your issue seems to be sorted. I would have thought a break in a wire would cause a more permanent error though?

I’ve not driven my XC90 as much of late as I’ve got a new little electric car I run around in. I also took the OBD power unit I was using for a dashcam from my XC90 and put it in my electric car. It’s the Garmin unit and has the option to run for 10 mins, 24 hours or permanent. I’m wondering if this unit was causing sufficient drain to give this 12v error as whilst I haven’t driven the car as much, I’ve not had the error since.

With regards to your question GMcL, I do have the recon option on my CTEK. I also have the charger connected to the terminals and not negative to the body. If there is a convenient place that I can attach the negative lead of the charger to (loop fitting) I could do that. Does anyone know of somewhere suitable?

Many thanks
