Facelift S/B lights

[martinivw]

I am having a problem with my "Right Rear Light" on my S/B facelift rear lamp,
I turn on the ignition and the outer lights get five quick flashes (I think the flashing is normal as my last sportback done this also with facelift lamps) then after around 5 mins the lamp goes out & I get this dis warning "Right Rear Light" this happens whether the lights are on or off, ALL other lights on the unit are unaffected!!
I have just been out and dis assembled the unit as I know that when u split it to change a bulb there are three contacts on the black piece that the bulbs are on and the female conectors are on the red part of the unit.
Kill the lights and switch them on again and light Is ok for another 5 mins
Any one got any ideas as this is driving me nuts!!!!!!!!

Ok this is insane!!!!
Lights are fine with ignition on or off absolutely no probs ,
It is only when I press the brake pedal that my "Right Rear Light" goes out and the dis warning comes on,
How on earth do I fix this without turning my lights on and off , if I can????
