Viewed L322 - few fault codes - anyone?

viewed a TD6 today, guy told me it'd had the steering column repair/recall done, asked to see the paperwork and he handed me some print outs of Fault Code Diagnostics, which i am a bit concerned about. They are:

P0380 glow plug relay failure - glow relay defective/power stage idle - open circuit/short circuit to ground

P0575 - speed control malfunction - speed signal failure

CAN BUS FAULT

CAN-BUS OFF (PREVIOUS)

DRIVER AIRBAG FIRING CIRCUIT 1
DRIVER AIRBAG FIRING CIRCUIT 2

STEERING ANGLE SENSOR INITIALISATION
Rear right wheel speed sensor open circuit
TEMPORARY SYSTEM DEACTIVATION

Many thanks in advance

I think the Speed Sensor fault might relate to the ABS sensor on the wheel. Had a similar problem on my last car, which required a new sensor.

Walk away. There are far too many out there without problems to consider buying one with.

Cheers people, anyone else know of the others and what they are?
