Does anyone know the location of the parking sensor ECU module for the B78? My rear sensor stopped working a two years ago and Citroen diagnostics said the ECU is faulty and were trying to charge me £1,000 to repair as I was 1 month out of warranty and 65k on the clock. Any help would be great as I've found the part on eBay, cheers

Any help on the location would be helpful, I think it’s either in the boot arches or under the seats, I don’t want to start stripping and then find it’s not there

- Click Here -
Use either your VIN number or select your vehicle model.
It will show you the part numbers for each area of the car and also the parts diagram.
You may be able to find the part numbers you need and Alos their location.
