Airbag

[drunkshopper]

Hey guys, this is new first post with this name... Some of you might still remember me. I was gtisurfer (Clay), Anyways I had sold my gti a while back ago, but the girl still has here 2.0 slow. An I am having a problem someone might be able to help me out with. Her car needs to be inspected like last week, and her airbag light is on. I pulled the code and this is what I got:
01638 - Crash-Sensor for Side Airbag; Rear Drivers Side (G256)
28-10 - Short to Plus - Intermittent
I am trying to figure out how to fix it or even where I can buy a new sensor. Thanks for all and any of the help, and to the ones that remember me, how is it goin?
