So driving home today, held the "set" button in and just had a bit of a tap around the steering area, was able to get a "cruise not available" error pop up, and continue popping up whenever i pressed a cruise button. Showing fault code P0570 which seems to relate to the set button, so the signal is obviously getting through. I'll order and replace the switch pack and loom just to be on the safe side
So update, new clock spring and steering wheel control, still no cruise. Have a new clock spring to SWC loom coming, see how that goes.
Anyone got any other ideas?
You haven't responded to posts 25 and 27 from BradC.
Have you looked at your LIN module?
I have no idea what it is, but I'm willing to bet my 95 300Tdi Defender doesn't have one.

Does the D4 cruise rely on an accelerometer that might need calibrating? "Longitudinal Accelerometer Sensor calibration."?Quote:

I don't have a D4, so I'm clutching at straws.
So! Thanks for everyones help on this, it's been a whole ordeal.
Turns out it had nothing to do with the cruise at all, and the park brake was SLIGHTLY dragging. Readjustment of the park brake and everything is working as it should.

Quick question if I may. How much did you spend on "parts canon" parts before you discovered it was a mal-adjusted park brake?
I know these are complex beats, and I'm not doubting your diagnosis, but I'm really, really struggling to understand how a dragging park brake could cause the cruise control to misbehave. Like so badly you can't operate the GAP tool on the dashboard with the cruise control buttons.
I keep adding 1 and 1 and coming up with 3.
I wonder if the EPB switch with its multiple contacts was the real culprit although I would have expected a DTC if it was both on and off.
How was the slightly dragging park brake discovered?
