Astra possible airbag/seat belt problem

I think seat belt tensioning is a mechanism for adjusting the tension in case if impact, rather than the static test you've just applied.

"Sie" mumbled:

Set belt tensioners are spring or pyrotechnic devices which on sudden decelleration snatch the buckle downwards pulling slack out of the belt. It's possible that there's a fault with one of these...and you don't want to go playing with 'em without reading the manual first!

BTW, seat belt /grabbers/ are different. They're in the reel and engage a set of spikes into the web as it leaves the reel so that excess web isn't payed out after the reel has locked by the webbing pulling tighter round the reel.

The only way to diagnose what is wrong is to go to a main dealer or other garage with the necessary dagnostic computer. The computer will come up with a fault code relating to the component in the airbag/seatbelt tensioner mechanism that is faulty.

First check underneath both front seats. There are connectors under each seat through which the seatbelt tensioner wiring passes. If these have been disturbed and are not pushed together firmly, then this will bring the light on.

Sorry don't think I explained my tests well enough. I tested them by snatching at them until they lock as would be the case in an accident. Which they do adequately.

But that doesn't test the seat belt tensioners...as I explained up ^ there somewhere.
