Airbag Light stays on!!!

[glen.r.read]

Well i have trawled through the internet and have not come up with much on the subject...

Unfortunately i purchased my 1.2 Ibiza with the airbag light on in 2006, the (Nissan) dealership i bought it from said they would sort it for me, so they took it to the local dealership and it was turned off... not sorted! As you can guess it came back on within the 3 month warranty period so i returned it and the same was done again...

It turned on again after a few months this time, so i took it to the SEAT dealership directly, i left the car with them for a few hours and the manager said he had turned the light off for me again, but he said he would need the car for 2 days to find the direct cause of the fault... this sounded a bit pricey... so i held off at the time.

I took it to various garages over the past year, all giving me different reasons, cabling to ECU, Seat belt pre-tensioner, connectors under seats etc... Also if the light was on the airbag would still activate in the event of an accident!!! Well what is the point of the light then??

So getting wise to the turning the airbag light off routine, i found a local garage that would just turn it off for me when it came on... which was great until it kept coming back on!!!

It came on so frequently i started to begin to think that weather conditions turned it on (just a theory) wet and cold conditions seemed to trigger it. Would there be any vulnerable areas on the car?

Really i am pleading if anyone has any information, if they have had this problem?? How i could go about getting it investigated and sorted once and for all.

I'd reckon that no one will honestly be able to give you any more good clues to add to what you have picked up already, ie connector under seat - especially if the seat is moved back/front a lot, cabling to the CONTROL UNIT, CONTROL UNIT, pre-tensioners or the clock spring in the steering wheel. The VAG tool or VAG-COM or some other scan tools should narrow the possible areas down a bit, that is where the Seat dealer with his two day visit comes in - maybe down to trial and error!

Thanks for the quick reply...

I also forgot to mention the VAG error code that appears on the system.

01312 Powertrain Data Bus
37-10 - Faulty - Intermittent

Not that it will narrow it down anymore, but i do not move the seats, i am the only driver, and very rarely do i have any passangers in the car. The seats are as far back as they can go, i am 6ft 3 so i need all the leg room i can get

I am just hoping that someone somewhere is having the same issue or has had the same issue, and how they resolved it. Massive long shot i know...

If I were you I'd use the search function on this and the Skoda site as I'm very sure that you are not the first to report this problem and have that fault code.

One random thought - battery voltasge - is your car a petrol engined one that would easily start with a goosed battery? If so, then it could be battery voltage that is causing this problem and causing it more so now that the weather is colder, also is the charging system okay - no steering system warnings?

Honestly i have gone through as many Audi, Skoda and VW sites as i can to see if the fault code has arisen anywhere... it has on most but no one seems to post a way of solving it!!!

I have had the car for 2 years now and it has always had the problem, it is a 1.2s petrol engine, I have never had any problems with the car starting, never had a flat battery or anything like that. So it might be a good idea that i get the battery voltage checked out.

Yes, I was going to re-post and make sure you were expanding your search to include any VAG forums - but that did not work either, and yes, now that I think more about that error code, it does seem to be one where no one has come back with any definative root causes - but unfortunately that does happen a bit too often! I'd reckon that you do not want to consider that the controller is itself faulty yet - but if you do, and if this fault is coming on a lot and so is inhibiting the SRS system, then maybe you should talk to BBA-REMAN (www.bba-reman.co.uk) and after you find out their price, remove and send them your air bag controller to check over - that way at least you will have checked out one possible problem area.

One other thing, have you been searching the VAG-COM sub-forums of all the VAG sites and the VAG-COM sites.

Not that I like to resurrect issues, but this one... 2 years on is still unresolved for me!

I had an issue with a c02 sensor on the car recently and the technician plugged in the VAG-COM to clear the code, obviously the airbag light was still on the dash, and I just queried with the technician if the 01321 code was still showing to which he said yes.

I have been looking on the Ross-Tech site to see if there has been any known issues on there but nothing really making any sense!

The code I managed to note down of the VAG-COM was: 01321 control module for airbag J234

The possible solutions on the site said check CAN-Databus Wiring/Connectors from/to Airbag Control Module (J234) Check Measuring Value Blocks (MVB)/Usually Measuring Value Blocks (MVB) 125+ show the current Communication Status.

Just wondering what this would entail in terms of getting in checked, but I have been pondering upgrading to a Leon and would hate to sell the car on with an issue.

mine is doing this at the moment as well.

mine is also doing it first happened during a severe cold snap and the battery died... I haves used vcds to clear the fault but it returns as you mentioned earlier.

It's funny that you mention a cold snap... I had the light cleared last October and garaged the car over winter only using occasionally! I went away for 2 days in February and left the car parked outside and the next morning the light turned on! I questioned then if it was the outside temperature which affected it!
