Evening all!

So I’ve recently replaced the LH rear brake pipe after it “popped” on the drive home the other week (completely rusted through) and also replaced the caliper and carrier too as they were in a bad way - all seems ok after bleeding modulator and system with Nanocom and a friends right foot!

However I had ABS/TC and handbrake like illuminate on a drive last week but it went off/cleared after stopping and starting again with no fault registered on the nanocom.

I’ve been unable to trigger it again but it came on again today after a drive down/back up a bumpy lane. Cleared each time with a stop/engine off and start again and no faults showing on Nanocom. So I’m a little stumped

Any thoughts/suggestions/pearls of wisdom from anyone on areas or things to check?
ABS and TC seems fine under normal operation (I haven’t don’t the fix to the shuttle valve - could this be a culprit?)

The front hubs have been replaced (by me) with new, genuine, parts about 3 years ago after both the original ones throwing faults up but rears are both original- I was initially thinking it would be one of these but with no faults showing it seems odd so don’t want to replace for no reason

Hi, some things to clarify:
1. just the ABS and TC lights no other?
2. is your D2 facelift or not?
3. can you see the HDC warning on self test after you turn ignition on?
4. do you have diff-lock?
