Headlight Not Working ???

[magoo]

A possible reason for the cut out is the computer management system or whatever it is called is measuring currents and see a discrepancy and bingo the engine cuts out.

This was the cause (hopefully) of a cut out/non starting and lumpy running happening in a VW Fox, wasn't aware the brake lights were permanently on, taken to several recommended garages with some saying get rid as the engine would need taking apart, none spotted the faulty brake lights.

Took it to a a diagnostic equipped garage and they identified the possible cause within 30 mins, dodgy brake switch and a pair of chaffed wires above the pedals.
