Quick updates, been busy on eBay managed to get a second hand multi-function steering wheel with air bag for £16 only wanted the airbag, (but had to do a 80 mile round trip to get it).
Then brought a slip ring off eBay for £17.
Went to fit the air bag and slip ring today and when I moved the slip ring forward found the plug had come off. Refitted plug put it all back together. The loom was tight so re worked it.
Interesting I found an old rusty T25 socket bit by the slip ring so some one has been in this location before.
Reset system with B800 now all ok
FAULT LIGHT HAS FINALLY GONE
If anyone lives near Dartford Kent you are welcome to use my B800.
So total costs:
B800 £21 off eBay from China, delivered in a week
Complete Steering wheel with Air bag £16
Diesel (in my cay) £15
Slip ring £17
Total £69 my local mini specialist wanted £50 just to look at the codes. Plus might sell the air bag and steering wheel so might break even.
