HDC, ABS ESPand inactive suspension?

I thought I would start this thread with HDC INACTIVE , Air susp. inactive with can bus error 50. I t also coincided with ABS ESP ETC. This had an error with no plausible signal at the time from rear right sensor .
I was on the middle of a long run of 300 mls with no faults whatsoever . Very strange , I stopped in a layby and switched off and started the car again and was back to normal, well only for 30 miles , so after a another 30mls to home I stopped and reset and again everything ok , except that both rear brakes were hot !

L322 2004 Diesel
The codes that I mentioned were cleared but not been anywhere since . Alot of confusion I guess in the can bus.
What I can do is try the steering turn to turn , .....I will let you know .
Incidentally before the run I changed the inner tie rod , perhaps that is to blame , but I had covered 300 mls after that ?

Much help appreciated.
Cheers

Check all the abs sensors and wiring.

No sooner you said that went to move and presto everything working again , but your right , I will have to check everything.Im just wandering if when I changed the inner tie rack rod I stretched the level sensors too far by jacking it to extreme at one corner. But then travelling 300 miles under very wet conditions to then appear with the fault, doesn't make sense.

If It happened in wet conditions check the connections for water ingress.
