Help please - retrofit electric seats stopped working, not blown lubar support fuse?

[youngsyr]

Hi all, I've just retrofitted a fully electric adjustment heated seat in place of my manual adjustment (electric lumbar) heated seat in my 2014 A6 C7 Avant and initially it worked perfectly.


However, my wife took the car and reported back that the seat didn't work from the first moment she tried it. I've checked the fuse (It's a RHD car, so position C10, red fuse box on driver's door side of the dashboard) and it's a 5A, and it hasn't blown. The lumbar adjustment also still works, but not the height and tilt buttons.


This has me stumped as I expected it to be the blown 5A fuse?


Are there any other fuses I need to check - strange that the lumbar support works but not the rest of the adjustment.


I fitted the seats this afternoon and played around with all the adjustments and heating - all worked perfectly?

Have you checked every fuse? Also if you can still see the hall sensors fitted on the rails make sure they are still in place. If you can manage to get to the plugs you are better off disconnecting them from the car loom and applying power there to the seat side.
Check if there is power to the car side loom and if so then work at the seat side as to why its gone off.
