Looking to buy a 2000 E430 Computer. Called the brain box also. Please let me know if you know of a place I can get one cheap. Car wont start, mechanic says that it is due to no power or electricity to the injectors or so. I'm in houston TX. I have got prices from $99-1,500. I have no Idea why they vary so much. My car would crank but not turn on. It would cut off after cranking for about 8 seconds. When it would cool down the car would start again. Weird!!!!
