Range Rover Computer woes

Folks, I am currently on my third RR, this one being a 2013 Range Rover Vogue SE (New Build). Ive never posted on this site but always managed to pick up some good stuff so here goes for my first ever posting and I do hope that someone among the RR experts out there can help me.
Recently I have had issues with the car that I strongly suspect are computer related. First the cruise control stopped working, then the sat nav and more recently the suspension ie I am getting a suspension fault warning intermittently but the suspension still works in both directions.
Otherwise the car runs perfectly but as you can imagine, the 'issues' are bloody annoying.
So, before I go to my dealer and chuck money into a hole I was wondering if there was any non-dealer related fixes out there eg companies that reboot the computer etc?
Your advice will be greatly appreciated and I am sure worthy of several pints.

I don't own a rangie but my understanding is that the suspension has a separate ECU to the engine so I think your issues are not down to one fault. This seems common on range rovers.
