So i go out to the car this morning to take the kids to school, not a single light on, all working well, even the speedo, stopped at the school and kept it running, suspension fault comes on, then the 'Xmas tree' appears again, stop at fuel station and lights all off again, driving a bit further and the suspension light appears, stopped for 20 minutes and nothing back on all the way home.
Surely this has to be a bad connection, faulty sensor, could it be related to the TCCM as i cleaned it off the other day and it did not work, could it be connected?

It could be the TCM, and it could just be a faulty brake light switch! Do you have "live values" on your diagnostic tool so you can actually look at the performance of components via the ECM's.yµ (idµ - eAµ) ψ=mψ

Just thinking in the absence of DTC's another area often to throw up issues like yours are the suspension connections behind the N/S/F wheel arch cover.
Sometimes its moisture, sometimes its just corroded connections or a combination of both. Inspect them carefully looking out for chaffed wires, its a pretty common enough fault on 10yr or more vehicles!
Easy fix!
I think there's a few threads on here regarding same.
Edit:
Yours may have a connection behind the L/H headlight!yµ (idµ - eAµ) ψ=mψ

I'd be inclined to go for the wheel arch, but the one behind the n/s headlamp is just a matter of pulling the square hoop and it will separate. No need to pull the headlamp.yµ (idµ - eAµ) ψ=mψ

So driving the car this morning and the only issue again was the suspension light, I suddenly remembered the advise given by a wise man on one of my previous D3's, something along the lines of 'you have to drive these cars to get the faults to clear, just clearing the codes does not always work, funny thing that this seems to be the case again, cleaned the TCCM up and drove it, now down to one light...'
Got to love this forum for helpfulness and knowledge.. Cheers Den!!!‘Everyday is a school day!’

Good morning sir!
Hope you’re well.
Did you ever get this fixed?
Seems I have the exact same problems on my 54 Plate.
