Hyundai i10 airbag warning light - intermittent fault

chubsta

I have an issue with my Hyundai i10 - the airbag warning light came on for about 2 weeks and I booked it into the dealer to be looked at (it is just out of warranty) - the day before I was due to take it up there the light went out! The dealer checked it and found an historical fault code relating to the airbag clock spring voltages in the steering wheel but didn't go any further, they said it was pointless taking the steering wheel off etc as they wouldn't be able to find where the low voltage was as it wasn't happening at the moment!
Took the car home and a week later it came back on intermittently for a few weeks, now it is off again, so it is going to be a real pain to diagnose!
I have found that I can sometimes make it go away by adjusting the steering wheel height or giving it a thump but this doesn't always happen.
I need to get it fixed but not sure if I should try taking the airbag off first and taking a look to see if it is a loose connection - I had the part replaced under warranty just over a year ago but the warranty is now over. Given that it is intermittent and sometimes reacts to the steering wheel adjustment, and that the part is only a year old, is this likely to be worth a go as I imagine it will be an expensive job to get fixed at a garage?
I have viewed airbag tutorials online so am aware of the dangers and techniques to remove them but wonder if anyone else has done such maintenance themselves?

Clock spring, not click spring.

What's the actual code?

have you checked the connectors under the drivers seat?

Sorry, 'click' was a typo...

The code was B134600

haven't checked the connectors under the seat, if I were to do this should I disconnect the battery for an hour or so beforehand just to make sure nothing gets triggered?

No need to disconnect the battery, the drivers seat connection stop the air bag activating if no one is in the seat. On my daughters first car this connection wasn't tight and used to trigger an air bag warning occasionally. A quick spray of contact cleaner, push it in tight and tape it together with duct tape and it was sorted. Certainly worth a try before paying a dealer @£80 per hour to investigate.
