Had my fl2 plugged in today to check a couple of faults.all ok apart from one issue we know about. There is no power feed going to the driver's heated seat. Switch lights up, fuse ok, what would be the next thing to check on this to find the fault??

If it has been working before could simply be a loose connector - there are plenty under the seat
Failed sensor or broken wiring

"Fiat Lux" a philosophy not a car

While some one comes up with a all singing and dancing reply why not disconnect battery and hold leads together for 10 minutes.

A bit like re-setting the computer and got to be worth a try if fuse is OK. FL2 MY10 TD4 GS traded in at 2 years

Has that been known to fix this issue before though?? I dont have a radio code for it though surely that would wipe the code?

No Code, only earlier LR's with single din audio.
You say you had your car "connected" was this at LR with SDD?
If so there is a specific "service function" for the heated seat network which would have diagnosed your problem.....did they carry out this procedure? They should have!
There is 3 wires to the Heated Seat Module, Gnd, constant pwr & LIN. You will only get power from 1 wire, Red from memory and only when ignition is on, did you have ignition on? Did you get power? If not check
Fuses and relay in rear CJB.
You really otherwise need to get the system diagnosed via SDD to pinpoint the problem, guessing otherwise. MY15
