Thanks for all your fast replies! Very helpful!

Initially it would not connect to clear any faults..
Then I removed airbag control unit from under centre console and had it reset and cleared.
He showed me before and after… before it showed faults on nearly every belt and tensioner!
After clearing it didn’t have any faults.
After reinstalling it was good for a few days now it has come back with one fault that I suspect is correct (airbag slip ring)
He mentioned it might be a cable inside the slip ring.

Apologies for my lack of knowledge… as you can probably tell I’m no expert with cars or anything involving codes etc.. but I would like to try and solve this issue as cheaply as possible.. the car is old and I suspect it hasn’t got much life left.
