Hi all.
I’ve had the dreaded electrical circuit failure, have car repaired fault.
Where can I get a new control module?

It’s the box with all the coloured wires on the front of the battery.

Thanks in advance.

I had that on mine, I left it for a while as to start with it was intermittent but eventually stayed on all the time. My battery was checked and that had a charge of 75/80%. I had a diagnostics done and the battery protection unit was found to be faulty.

It took four weeks to get one from France. I don’t think it’s just plug and play and has to be matched to the car.

The cost was £440 and although my car was three years out of warranty my dealer manage to get a 50% contribution from Citroen.
