What's this?

[Bingley]

Finally got around to getting a full size spare for my 103TDI 4x4 Yeti - it actually fits quite well where the silly space saver tyre is! Now I came across this gizmo attached to the floor just behind the rear seats and in front of the spare. Anyone tell me what it is? Guesses include aerial for the key (I have kessy), something for the tyre pressure warning system (which I dont have), fuel gauge sensor........
