If you can get a gap tool and post a log you'll get more responses. Most of us can you tell with somewhat certainty what the issue is if you do that.

ok Im using an iCarsoft LR V2.0 for Jags and LRs diagnostic tool.
And new to using it.
I cleared all the faults so I believe I’ll have to wait to see if this problem crops up again
today is when I found the trk dead got a jump and found a really loose negative connection? Retightened both and it’s been ok right now also found a blown side marker bulb and replaced it time will tell.
thanks for your reply

Bad battery voltage, grounding issues, and even burnt brake light bulbs cause all sorts of mayhem with the LR3. They most commonly throw Uxxxx and Bxxxx codes due to those problems, which is mostly what you had. Hopefully by fixing those issues you will have cleared up your problems.
