OBD or OBD2

I have a 1999 E46 323i se auto. I'm trying to work out what software/connectors i need for diagnosis. My car has the old round type plug under the bonnet but it also has the plug in the drivers footwell area. Can i still use the round plug to reset my service light?
Is this car OBD2?
I currently have an airbag warning light on but the stealer says no fault code was present and reset it. Only for it to reappear 2 days later. I think i'd be better off buying the equipment and finding the fault myself.

You should be able to use the plug under the hood to reset the service light without any problems.

If you are in the US, then your car is OBDII -- all cars beginning with model year 1996 are. I don't know when the standard was adopted in Europe, etc. It may have been in 1999 or maybe 2000 -- I am not certain.

The two ports you are talking about are completely different things. OBDII is a standard that car manufacturers have agreed upon (the one under your steering wheel). The round connector is a BMW propietary connector that is used for several things, including resetting you service lights, and I believe diagnostics also.

About the ABS light: that is usually a dealer thing. That they found nothing is kind or weird. Did you check your safety belt clips? I hear those being faulty can fire your BAS light. The thing is that I don't know of any tool available in the aftermarket to read your ABS diagnostics. Furthermore, I seriously doubt that buying the equipment would be more economical than having somebody fix it.

Oh -- and welcome to the board
