Bought a Gap IID tool which I'm starting to find my way around. I'm trying to resolve an issue with the parking sensors. When I look at the live values and choose Parking Aid, one of the rear sensors doesn't list - does anyone know if this is indicating a fault with that sensor? I've tried swapping sensors over and it still doesn't list the same one - possibly a fault in the rear bumper loom? Any help would be appreciated.

I have emailed Gap but with the time delay I thought I'd post here as well.

I would say there something wrong with the loom if u’ve swapped good sensors to where the bad sensor is but it’s still showing faulty. It could be a bad connection on the loom side.

Yes, I think I'll need to swap out the rear loom, it's probably about an hour at the most and I've spent too much time trying to track the fault down.

But otherwise, six months into ownership I'm pretty happy.  2013 405 TDV6 Vogue SE Barolo Black
