update-took it to a garage,he seemed decent-the boot lock had part of the mechanism missing so he has fixed that.With the airbag light he has run diagnostics and it says the fault is with the sensor under the passenger seat.
He has taken apart cleaned and reconnected with no joy and says there are no losse wires,so he isnt charging for the diagnostic which is decent and im taking the opportunity to have a basic service while its in.He did say that there is no problem with the airbag and so when mot is due he will ensure it passes.However,bizzarely, over the last few days it is becoming more intermittent and is going off more regularly- im wondering if iot could be the valeting if it got wet and is slowly drying out,taking longer in the current weather?
