Car Will Not Start Problems of BMW 545

While driving to work during morning rush hour in a busy highway the car just stopped running. No odd sounds no shutting no clunking. It was like some just turned the key off. I made it to the side of the highway and had to wait two hours for a tow truck to show up. Most of the week previous to this my car would not start at random times even though my battery was good and I had gas. The problem was the dme had water ingress from a poor location where the dme and metronic computer and the intergraded power module are located and stored. They are in a sealed plastic box under the cabin fresh air inlets and cabin filters and the front hood cowl. I'm the box there is a fan at the bottom to expell moister. If the intergtated power module starts to go then the fan stops working or the fan it self goes bad. At that point there is almost always water ingress into the dme and or the metronic computer causing the car to not to run or even crank and with water corrosion on the the dme it causes phantom problems in other areas of the car. The dme is also not easily replaced. The car had to be taken to the dealership and they have to order a new dme and align it with the be cas module for the immobilizer to work correctly and for your car to start. This usally cost in excess of $2,000 just for the new dme. The worst part of this whole thing is I lost my job because I was 4 hours late to work after waiting for the tow and getting a ride to work.
