Yo will need to have the airbag code reset. There are some OBD readers that can do this, the cheapest one I could find was the Autel MD802. It was $168 from Amazon.

In the future, I'd just get a battery maintainer and plug that in while the car sits, rather than disconnect the battery. I use a C-TEK 40-206 MXS maintainer/charger. I think it was about $70. You never know what the Boxster brain will do after being disconnected from the battery for so long.

I don't think that the airbag light will matter for a smog check, but you may have to drive the car for a while for the systems to show ready for the OBD. If it was disconnected from the battery, the timer on that may reset to zero. Another instance where the OBD scanner comes in handy, it will tell you if all systems are go.

In my opinion, owning an OBD scanner is part of the cost of owning a Boxster!
