Depends on the spec of your car. If you have curtain bags then there will be connectors in the boot, at least that's where they are on the 156. Multiecuscan will tell you which ones are giving the fault. It could also be the airbag control unit playing up. I'm currently trying to source one for Kingdom as when he came round on Saturday that's what we discovered his fault is.

The the boot of 147, there are on both sides next to the cables for the rear tailgates in the "pockets", you cannot miss them yellow ones.

A galleon

A pal came over on Saturday. We hooked up the lappy and used the cable with the red adaptor (previously proven to work to read airbags). No dice.

It connected without the adaptor to read engine ecu etc. With the adaptor it wouldn't connect.

Any ideas?

Did you select the correct ACU in the menu? There's often more than one to choose from.

Hi Tom thanks for all your help the other day.

I have had the ACU off and it is module No is 60669250 where is the best place to get one?

There is none on ebay at the moment, bought one which I thought would be compatible module No 60669249 but wasn't, what a pain.

What do you suggest?

As Tommywho156 says, it is in the 'how to' section at the top of the 156/147/GT lounge: however, it is not labelled as such (there being no 'how to' section).
Instead you will find the full thread as item 6 of paintergirl's post #3 under the heading

or just click

You're gonna need this, people, you won't get through the MOT with the light remaining on!

Only 33 1.8 TS Veloces left, and counting...

Just want to say a massive thanks to TommyWho for this thread.

My GT is going in for a service and MOT tomorrow and has had an airbag light on for the last 6 months or so, so tried this fix this morning and hey presto it was the contact under the passenger seat. Bit of contact cleaner and its as good as new!

Only took me about 15mins as well, was a bit naughty and only disconnected the battery for about 5 mins before starting work.

Happy days!!!

Again airbag light, starting to think to take the gasoline and start the FIRE :@

I was at my mechanic, but the fault didn`t go away. It is passenger seat, value too high. Tried 2 times to disconnect and connect but still the same, the fault didn`t wanted to go away when deleted.

Is there any other connector except the one under the passenger seat?

Second, I guess in case of car crush all airbags will not be deployed?

Maybe you may actually have a faulty airbag if the quick fix is solving the issue

Thing is, I had before problems with that connector and it always solved with remove, spray and clear the error ...

Well, this time, mechanic tried to clean it with WD40 o.O and without removing the - terminal of the battery...maybe this is the reason...

Now I want to try, first to clean with 96% alcohol to remove all greases, they with contact spray, and normally remove - terminal while doing this. Then if I have the same problem, to solder the wires (going to need your help what goes where just in case) and try again and if again this doesn`t help I bill spill a diesel fuel and burn it.

Thanks for your time.

BTW those Siemens connectors are the worst thing I have ever seen, overcomplicated things,

Fantastic post - saved me buying a new car. . . .

I just wanted to thank you so much for this information. I had the dreaded airbag fault light, and even my very trusted local mechanic who is Alfa main dealer trained, shied away from fixing it saying it would cost more than the value of the car to fix it, but managed to get it through the MOT last year some how . . . . .

Today one year later it failed the MOT for the same issue, as well as an exhaust leak, I was seriously considering taking it to the scrap yard, but found your post. I knew it was the curtain bags at fault, and with the comments that the connectors in the boot were the ones to go for I followed the instructions and hey presto no more warning light, although it didn't cancel until I started the car a second time.

Thank you, Thank you, Thank you, Thank you, Thank you, Thank you, Thank you, Thank you.

Just need a new exhaust and I can continue to enjoy my beloved Alfa 156 TI

Big smile on my face.

alfa 156

It worked for my 156 1.6 (2004)

My 156 1.6 (2004) is now free of this stupid airbag fault light

Just followed the instructions as posted by Tommywho156 in the initial post with just two small changes:
a) different brand of contact cleaner, CRC instead of Servisol
b) a Led Zeppelin CD instead of the AC/DC one

I did not have to use the multiecuscan software after cleaning. The light went off after connecting the battery back!!!

Many thanks to Tommywho156 and the rest of the people who contributed to this discussion.

Usual red airbag warning light was on my '04 156 jts "0F side airbag"... cleaned connectors under both seats to no avail, as a last resort I cleaned also the three connectors attached to the airbag ECU and voila' problem solved...

+1 on that. Contact cleaner etc is an ultimate waste of time. The light will come back to haunt you again I had already cut the connectors off and soldered the ones under the front seats because that strategy didn't work. However, in the recent hot weather I was getting a curtain fault cropping up when the car was parked in the sun. Thus, I cut out the air bag connectors in the boot and soldered the connections. Problem fixed
