E53 Leather Seat Swap Seat belt Airbag issue
 

Hello Members!
I hope someone can help me with my issue,
So the deal is that I bought ainterior for my facelift x5 e53 and When replacing the seats I did not disconnected the battery, swapped over the front seats and now I have 2x error 1st is Both seats show Seat belt Buckle error (the buckle is with the airbag) and the airbag light is on the dashboard 2nd it shows Occupancy error,so the steps I tried to fix this was
1. Clear the error with INPA, P.A SOFT DELPHI ( NO LUCK
2. Replace seat belt buckles from old seats (swap them over ( error still there,
3.Disconnected the battery and left overnight (no luck

Both sets of seats are memory and fully electrical(basically identical,,,,)

To tell the whole story I was replacing the whole interior, door cards seats even roof liner, and to add to the issue after replacing roof liner my roof light will not shut off when pressed(even when press and hold) it will only go off if driving or doors are closed for at least 2 min or locking the car... tried to look into all cables no luck investigated fuses which are all ok...again roof line is identical to the one bought,,,,If someone can point out where to start tracking the issue I would really appreciate
THANKS!

The error for the seat comes from the fact that it thinks that someone is sitting in the seat and doesn't have the seat belt buckled. Probably a problem with the sensor mat or wiring, not the seat belt buckles. You could try doing up the buckle and see what happens.

Might be a bit of a pain in the ar se - but to rule out the new seats, perhaps swap the old stuff back in to see if the airbag lights will reset?
