Help car died on the way to work ( VEMS Display going blank also ? )

[Rally43]

My car died on the way to work this morning... Seems electrical , as the VEMS display goes blank when it happens.. Actually doesnt go blank but has 2 solid lines of blacks across the little screen.. Anyone have this happen and know where to styart to look for issues ?

Also would the IAT ( Audi with AAN Engine ) INtake Temp Sensor cause any of this ?

Thanks

Tim
