This morning my 2010 octavia's airbag light came on.  I 'think' I tracked the cause down to a broken yellow wire leading into the drivers door, which is now soldered back together. But the warning light remains until the OBD is cleared, so I won't know if it is fixed or not without clearing it.

 

I've borrowed a small device that'll do this. However, the car is booked in to be serviced tomorrow and I'm reluctant to clear things in case theres anything in the OBD that would be of use for the service. Does anyone know if its worth waiting until after the service, or can it safely be cleared?

 

Thanks

 

If it was me, I would do a code scan with VCDS then clear it. 

 

If it's stays gone, your repair has worked and you're good (assuming the repair stays intact, of course) 

Thanks. If the info isn't needed for the service I may do that, then. I've borrowed a modest VAG305 scanner, which as far as I can tell is a bit unselective about what it clears, but as you say i won't know until i try to clear it.

 

Though by this point perhaps theres not much to be lost by waiting, either. I could tell the garage to ignore it if there is still a fault, until I've had time to investigate further. 

Well, I couldn't get myself up in time to do anything this morning (the hot weather is stopping me sleeping!), so I just took it for the service as is. Whilst the computer is hooked up, the helpful chap has offered to check if the repair was successful and if so clear the fault for me, but if not he's agreed to leave it for now.

 

So that seems like a fair decision; either my repair will have worked, or if not I'll be able to do some more chasing down before deciding if it needs professional attention. I'm not rich and paying a skilled hourly rate seems excessive if it is just a case of finding and fixing more broken wires.

 

Looking at the forum, there are quite a few cases of the door loom fraying/breaking around the door hinge area. So it seems a bit of an odd choice to put the crash sensor in the door, opening it up for this kind of weakness. Presumably there must be a good reason for it to be there though, rather than in/on the chassis.
