Not sure what you mean by the battery, are you referring to the battery in the car?
I havent done anything yet. I tried reseting it with the vag system but nothing happens.
Yes. The car battery. If the system looses all power the air bag light will be on until reset.
Sounds like your is a fault with the air bag and will probably require repair. you might ask if it is covered with the l> Not sure what you mean by the battery, are you referring to the battery in > the car?
fwiw, the airbag indicator did not light up when I replaced the battery on my '00 B5 S4. Nor did it light up when the service department disconnected the battery when they had to remove a door and didn't want the lock pump to run all day...

problem with the wiring maybe? fuses ok?
I based that on a number of posts that I read on AudiWorld !4 forum but not on my own experience.
When a battery is disconnected to reset the system it is usually suggested to leave it disconnected for a number of minutes. That is probably done to drain off power from capacitors in the system so disconnecting briefly might not cause a reset.

i have a feeling its the wiring but im not very good at tracing it so i might have to bring it to the dealeship, but first i will check the fuse and also reseting by removing the battery..
I think some disconnect the battery AND touch both the neg and positive cables together to remove any residual charges in the system. TRY THIS AT YOUR OWN RISK!
I believe that water can really mess with connectors, so I would also examine the connectors well.
BTW the ross-tech.com tool, along with the most recent software, might be more specific with their scans/dtcs.
good luck, dave (One out of many daves)
