Many thanks to Tunnie for the heads up,info now back into English,looks like the brake switch is fubared as now no brake lights....going to have to drive VERY carefully up to Huntingdon next week 
Reminds me, a few years back I bought an Ex Plod Omega from Preston, Lancs, having already seen and tested the car, I went up by Train on a Sunday to drive it back to London, before jumping on the Motorway, I did some quick checks, Oil, Coolant, Tyre pressures, Bulbs etc, only to find zero Brakes Lights, quick visit to the local BP Garage proved fruitless as it wasn't the bulbs or any fuses, and decided it must be either a loom or switch problem, the previous owner must having been driving around like that for months.

As there wasn't much more I could do being a Sunday and lack of tools, I decided just to carefully drive it back and using, what was working, the rear fogs lights with the side lights on, using foot, brain, right finger on the fog switch as some sort of coordination to fake the brake lights. Needless to say being a Sunday, it was stop, start pretty much all the back, by the time I got back having just done 200+ miles journey, my right finger and brain was totally fc%ked,

needed a few beers afterwards that night.
