Mercedes W140 (S320L) - motorconsultant
Car has immobilised itself with lights on rear view mirror alternately flashing. Have tried both spare keys including wallet key with no effect. Does anyone know how to fix? Is there a sequence of reset to follow? NB: Car also has a habit of cutting out whilst driving. Happens at all speeds, all the dash lights come on, then engine cuts back in before you have stopped, very weird and quite un-nerving!
