Default Airbag light sorted, Big Thanks to Amar and Ranj

Hi All, This is my first post not sure how to do this, I am not good with computers, but here goes. I have had the airbag light on for around a year, its driving me nuts. So after reading Amars write-up on it, I thought I give it a to give it a go, My car is a 51plate S8, and vagcom was telling me its G128 passenger seat occupancy sensor faulty, So I followed Amars instructions and fitted a 100 ohm resistor across the blue and the white wires, which on my car made no difference, So i ran 2 wires up to the centre console to try other resistors to them,
So off to Maplins I went and bought a 1K ohm pot, and connected that to the 2wires on the centre console,Also I connected vagcom up to show Airbag measuring blocks, and I discovered that the 100R was giving me a reading "too low", adjusting the pot I could change the reading from "too low" to occupied to "too high", I adjusted the pot to read occupied, then erased any stored airbag fault codes, I didnt bother measuring what resistances caused the reading to change as its not important,I have achieved what I wanted, which is the airbag light to switch off.

I would like to say a BIG Thanks to Amar and Ranj for all their help in sorting this out for all the the people with this airbag light fault on their cars.
