Air bag light on ? Do you have a scan tool that can read air bag code's ? Light on ,code's are stored . As far as the P0629 code
DTC P0629: Fuel Pump Relay Control Circuit High Voltage
The engine computer is seeing high voltage which means there is P0629
The ECM detects the fuel pump relay control circuit control circuit is shorted to voltage.
Circuit/System Description
The engine control module (ECM) provides ignition voltage to the coil side of the fuel pump relay whenever the engine is cranking or running. The control module enables the fuel pump relay as long as the engine is cranking or running, and ignition system reference pulses are received. If no ignition system reference pulses are received, the control module turns OFF the fuel pump. The fuel pump relay control circuit is equipped with a feedback circuit that
is pulled up to 2.5 volts within the ECM. The ECM can determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.
Your best bet , take it to a qualified repair shop

You need access to VagCom (the diagnostic software from VW and Audi). You can download it free at www.ross-tech.com, and buy the interface cable for your laptop on eBay for about $20. Or you can pay an hour's labor at a VW/Audi dealer to have them turn off the light.
What probably happened is similar to what happened in my 99 Audi A4. I have side airbags in the seats, and if the front seats are moved all the way back for any reason, it puts tension on the yellow airbag connector under the seat. That pulls it out just enough to open the contact and trip an airbag failure light. What I did was zip-tie the connector tightly (be very careful of the wires, as they're small and you don't want to pinch them), then use VagCom to turn off the light. Using the software is the only way to turn the light off - no ignition cycling or drive cycles, or number of miles driven, nor a battery disconnect, can reset the light.
Use VagCom to find out which airbag is giving you trouble, zip-tie its connector, and have the light turned off. Then you're set.

Since my last post, I found a bright yellow connector under the drivers seat. I took the connector off of the end, bent it a little, and put it back on. My air bag light has stayed off. I am going to put some electrical grease on it and see what happens.
SOURCE: 2007 Passat wagon. I need to reset the air bag warning light.
the air bag light will only show if the ignition was turned on while it was disconnected.
it will defo need to be pluged into the computer to be put out but some smaller garages will have the software to do this and will be a little cheaper.here in ireland VW wanted 50euro to do mine but a small garage done it for 30euro.
you can buy code finders/reset gadgets on ebay but might not be worth it for one job compared to $130.
my suggestion would be to get the main dealer to do it if a normal automotive shop cannot access it.

There are a few things that can cause this, either the air bag itself going bad, or an airbag sending unit or brain going bad,

It likely is a bad passenger air bag. Did you try switching it back to off on the switch,and unhooking the battery for 5 minutes.
