Scan faults

[Simonbartlett]

I have just done my first scan with my new obdeleven, first scan had quite a few codes ( nothing engine or gearbox related ) so I cleared then and went for a drive.
The only ones that come back are

Control module incorrectly coded 01044 gateway module
( not sure what this does )

Touch sensor short to ground drivers door and rear left
( strange thing is it's the passenger door that's paying up these two work fine )

Left footwell heater no signal
( would this be knackered or could it be a loose plug ? )
