807 front parking sensors not working

[Romtag]

I don't suppose you or anyone else has come across an interior trim removal guide have you? Google throws up nothing of use other than door trim removal.

Ok, so you won't get any errors if the parking assistance ECU itself has been disabled in the BSI. But as we know the rear sensors are working fine, that won't be the case. However, it is still possible that the Parking Assistance has been configured for rear parking assistance only, in which case the ECU won't be looking for the front ones which may be why there are no errors. If this was done as a result of the bodged wiring I can see why....

So don't be too daunted by the diagrams.

9025G: comfort data low CAN bus
9024G: comfort data low CAN bus

7519-7524 are the front sensor wires

When you get a chance, where you had that mash of cut wires, have a look on the sleeves so see what the codes printed on them are. They should have typically 4 numbers or 4 numbers and a letter. If you can find any of these with the wire colour, I might be able to ascertain what these are for. But the code is more important than the colour as they often use any colour going!

Which part of the trim? Can you pop a photo up of the relevant bit of trim?

I'll take a photo tomorrow as the car has been in a friend's garage for a service

I want to take the rear right and left trim out so I can check the wiring as I have a few loose wires that I need to chase back

Hopefully the picture makes sense.

Ps the air freshener is there because the teenager sits at the very back
