More than likely they dont have the correct software to diagnose the code
Airbag light on - Have you been affected? (UK)

After trying four 'Technicians' with their different diagnostic machines which all showed 'No fault shown' despite my SRS light being on for the past two months
I finally found a guy with a 'Snap on Diagnostic machine' who also had 'No fault shown' who persevered until he found a fault which said ' Faulty seat belt tensioner on REAR near side seat' despite Z4's not having any rear seats, he reset it and lo and behold my light has now gone out and works perfectly
It's hard to have any faith in BMW electrics

Has anyone tried an airbag light removal tool? If so how did you get on with it ?

Our local stealership says "no applicable recall" regarding my frau Janet's 2003 2.5 litre. They want $120 to read codes, credited on repair charges which could be substantial, they say. The airbag indicator lighted-up when a passenger briefly exited the vehicle, engine still running. No surprise, there are plenty of emulators to address the problem of a suspected seat mat sensor. I measure the resistance as ~1050 ohms, no load; under my 200 lb butt, the resistance goes up to 1100-1300 ohms inconsistently. An internet videoclip talks about 200 ohms in series with a 1N4001 diode for a home-made emulator; but otherwise I don't have a benchmark on this -- no Z4-owning friend to call upon.... unless someone on this forum has info to share. Many thanks in advance.... glenn in South Carolina.

The videoclip referenced http://www.youtube.com/watch?v=M6HsUapqNs4 indicates source as vehix411.com. The 1N4001 suggested to me that I should repeat the resistance measurement this morning. Remembering test current runs from the +ve side of my Simpson meter, I got the 1050 ohm reading again; but reversing the direction of test current, I see no continuity in the seat mat sensor. Quite likely, an emulator would include a diode. I will report success/failure of the home-made emulator in the next few days.
Hi, my airbag light is on since I bought the car (used) and I'm still not able to turn it off.
I made the change under the seat with the resistance etc but you aren't off needless with Inpa, the only result is that sounded to the seatbelt. So I inferred that it was not the pad and have it removed. Once removed with the seat out of the car I put the tester on the two wires that come out of the seat. the wires one white and one blue.
Putting the tester 2000 ohm scale I marked by not sitting and sitting 80.4 1, putting meters on 20000 1 marks from me not sitting and sitting 060 ... that value to you?

My airbag light went on. It was on for a few days while BMW dealer was working out the problem. Then I was driving at less than 20 mph down a residential street luckily with the roof down when my steering wheel literally exploded with a couple of loud bangs and dense dark grey smoke coming from the airbag (without any impact). I nearly had a heart attack! This was an extremely dangerous experience especially if I had been driving on a motorway with the roof up. I was told by the BMW dealer that the airbag should not be able to deploy if the light is on.
So the dealer has spoken to BMW who incredibly will not give me an explanation or anything else saying that an incident like this has never been recorded before therefore they will do nothing. I am still pursuing this because there attitude is unacceptable and right now I don't want to drive my car because there are a number of other airbags that could similarly deploy and also while I am trying to get some come back the car doesn't have a horn which is illegal. The quote for a new steering wheel etc is over a grand - not acceptable.

Hello
I have a 2004 Z4 SE 2.2i and in June got a service-new oil filter,oil & air filter- by an independent garage near where I work. Got the car back and straight away the airbag warning
light was on, and stayed on! I was going on holiday for a week the next day so left it till I got back to take it back to the garage. He put it on a diagnostic machine he had and it came
up with no faults! He recommended taking it to a different indy- incidentally where I bought the car 3 1/2 years previously- which I did. They had 3 attempts, on 3 different diagnostic
machines, all coming up with no faults! I want to sell the car in the near future but would like to clear this up first..............any ideas?

I had the same problem after removing and reconnecting my battery when removing my seats. I got a guy to fix the problem only to have it come back on after a couple of weeks
He reset it again and it came back on the next day
He wouldn't look again and told me that BMW electronics were a nightmare, he wasn't wrong there
I had a total of five people look and four of them said there was no fault showings part from one guy who said it was the rear seat belt even though I haven't got any in a two seater z4
Eventually I went to an Auto Electrician in SE London
He plugged his machine in and cleared all the historic faults and started again
It then showed a fault on a sensor on the main lead from the positive battery terminal up to the engine, apparently this is something to do with tightening the seat belts if your get a rear end shunt
The fault was showing to be on the drivers side seatbelt which he disputed because if it was the sensor it should show on both seats
One of the previous guys looked and it showed that I had a problem on the near side rear seat belt despite the fact that I havnt got any rear seats or rear seat belts
However, after thinking about the problem the guy in Eltham came up with his own idea to try which was simply to remove both battery terminals and give them a good clean and replace them doing them up tightly
Low and behold this solved the problem and all has been good now for the past 10 weeks
An easy fix and definitely worth a try
Good luck with it

Airbag light on. Diagnostic says faulty airbag module, many hundreds from BMW and then wants coding. they also said I could not re programme a secondhand unit but have found out I can.
