Both heated front seats seem to have stopped working. Switch lights come on but no heat. It’s a 2012 with heated/cooled front seats.

As it’s both, I’m assuming the fuse. Which one please and what capacity? 2012 4.4 TDV8 Westminster

Fuse 29 and 33 from memory, 20A

Thanks. Good guess!

Not the fuses though. Drivers side only as it turns out.

Any ideas before it goes in? 2012 4.4 TDV8 Westminster

I have the same problem, when I scan with the GAP IID I get this error

DCSM - Drivers Clim Seat
U0140-00 (2F) Lost Communication with body control module





and a lot of good info below in this mammoth thread - it might also help

I pulled the back off the seat, as per the video. Nothing wrong with the unit. I checked the fuse (29). Fuse is good.

I thought I’d swap the fuses between the front seats to make sure. No change. However, when I pulled the fuse to the passenger seat (fuse 33), the heater and fan continued to work as if it wasn’t part of the circuit.

Help…..

If it is the comms issue with the body control module, does anyone near Reading/Basingstoke/Camberley have a Gap IID I could plug in please to hopefully reset it. 2012 4.4 TDV8 Westminster

sadly no matter how times I reset the fault/error with my GAP IID it does not resolve it

After all that, it was the Peltier sensor. I found a brand new unit on eBay and fitted it myself thanks to the instructions on the long thread.
