      The light on means theres a fault in the airbag system. You can try to reset the light, but if there is a real problem, the light will just come on again.

      If you didn't reset the system after the airbag replacement, the light would just say on whether you fixed the problem or not.

      After any repair, it has to be reset so it can self test again.


      Read up.

      The light will automatically come on every 10k miles, it was set up by VW that way so the customer would come back into the dealership to have it reset as "routine maintence". It doesnt necessarily mean anything is wrong with the airbag system at all. To top it off it requires an "OBDI" scanner and the traditional scanners of today are "OBDII" so it will not work. OBDI scanners are pretty much obsolete, so good luck finding one. There are other ways to get it to turn off by messing with the comp and wiring, but Im not about to get into that one. Mine has been on for 5 yrs now and do not intend on getting it turned off unless I come across an OBDI scanner.

      Hey gambi, read up on that link I posted. We found a way to do a reset with a couple of wires and/or a specific pc program and the right cables.

      Disconnect the battery.
      Disconnect the wire harness connectors (#14 and #16 in the image above) located below the fuse/relay panel. On the smaller connector (#14 in the image above), find the two black wires that connect to T6/3 and T6/4 and splice them together (splice them without cutting, or cut both wires and splice all four ends together and system restoration is as simple as reconnecting the controller harness). Click here for a picture example.

      i bolded the portion in question

      On my cars, that flat connector passed so close to the fuse box, it was held in place by a plastic clip, TO the fuse box.

      The wires in that connection didn't go thru the fuse box...but it was in very close proximity.

      Then you did it wrong, read the instructions again, it's not complicated.

      Even if you correctly reset the airbag system...the lights will come on again IF there is an actual problem still existing.

      If there is NO current problem after reset, they still stay off.

      I have read the owners manual and It isn't in it.
      Matter of fact get your facts straight.
      I feel safer in my mk1 than any other car I drive. I have been rear ended, t-boned, and front smacked in a mk1 and drove away every time.

      I was rear ended by a full size F150 doing about 20 and only had a crumpled fender to show for it.
      The very fact that it is a convertible means it has additional strength and bracing that other cars don't have.


      If it was any other car, the whole back end would have been crushed.

      I think my car is very safe.

      Post a screen shot or photo of your owners manual to back up your statement and I'll apologize for calling bull, until then, Bull.
      Consider, if 10k, then to the dealer was true, "air bag lights are on on my '90 to '93 Cabby" threads would be as common here as "my fuel pump is noisy" and/or "my '80 to '89 CIS runs bad, I gots no Bentley, timing light, dwell meter, injector seals or idle o-ring what do I do now with no time, money or effort?" threads by '80 to '89 owners.

      Totally glossed over this one:

      No where have I ever encountered ^that statement in bold. No way, no how would Volkswagen (and Siemens for that matter) set up a time interval like that. That's absurd; customers would've been extremely put-off by something like that (Mk4 CELs, anyone?). The lifespan of the airbag is 10 years; the lights come on when there is a fault detected in the system and/or the 10-year time frame has elapsed. There should be a sticker on the sun visor giving the 10-year interval date as to when the airbag should be replaced.

      "Every 10K..." Good one. Yeah, I'd like to see a scan of the page that states that.

      I have read and re-read the Air bag section on my 92 and 93 Cabriolet's Owners manual, and re-read the 1990 one and the "closest" they come to anything related to a time interval is on pg 25 of the 93.

      "To assure continued reliability, the airbag system must be inspected by a qualified Volkswagen technician 4 and 8 years from the date of manufacture appearing on the safety compliance sticker (left doorjamb) and every two years thereafter. See your Authorized dealer"

      That is a bit more than every 10K.

      But I understand that it was Bush's fault and not yours.

      Seeing how it is only warrantied for 10, after 10 it would definitely be on you.

      That's funny, same thing is on my '92's drivers side sun visor when folded down to blinder mode. At least the 4 and 8 year stuff is there, I didn't notice the 2 year stuff, but I may have fallen asleep by then, no, I wasn't driving.

      for the record the splice fixed my problem, thank you to everyone for your input

      When my car hit about 128 k the light came on - reminds me of xmas tree lights, and now I hardly notice it.

      Oh and the car was 13 years old when this happened, now it's 21!
