I have this fault on my Nanocom. It is the second time I have seen in the last 2 months, as for the past 5 years no faults. I suspect it is something to do with using cruise control. Maybe the engine revving freely disagreed with speed sensors or something.
it doesn’t seem to affect anything to do with running.
I checked today as yesterday I had a no start with m&s lights flashing . I had previously not had the transfer completely in high and it jumped out ,so it could be that. I had to lock and unlock several times and it cleared. No faults in SLABS. Magic!

In addition a motorised Yamaha golf buggy started up beside the car and I suspect the immobiliser was triggered, seeing lock and unlock cleared the m&s.
bloody old computers on wheels!

car is 2002 D2 td5 eu3 auto with 200 k.
