A4 B7 seatbelt warning noise
Pull fuse 11, kills airbags, ABS, and ESP.
Otherwise I understand a software change is coming from Audi, as my dealer knows all about the problem.
The sensor is used to "adjust" the airbag to the passengers weight. Idea being to throttle the explosives somehow.
Sure it's a feature to let you know if you leave your headlights on but there's a very easy way to give you a "headlights on" warning using a $2 piezo buzzer from Radio Shack and the fuse block. If somebody knows a VAG for this (as nobody has ever found one), please post it up.
