she finally broke

after weeks of getting the oil pressure light coming on and off,my a4 2.0tfsiq broke down on the way to the garage.i had replaced the oil pressure switch about 2weeks ago.it seemed to cure it but it started again.on the way to the garage the light came but the engine sounded fine,about 1 mile away from the garage.the lights inside the car went really dim then the car just cut out and woudnt start.the bloke at the garage had to come and tow me!(really hard to drive being towed with no power steering!)
got it to the garage the bloke said it could be electric fault still waiting for him to get back to me!just hoping i dont need a new engine!
anybody heard of anything like this?

Was the engine turning over when you tried to start it?

could it be the turbo?
