My wife drives a 2009 X5 30idrive. Recently we had the water pump replace, fuel lines, thermostat and a few other things. We paid the $2200 dollar bill and drove it that night to my son's track practice. After practice the car would not start. The lights come on, the windshield wipers run wide open, and the dash lights come on. Other than those things nothing happens. We had it towed back down to the mechanic who had worked on it. They could not find the issue. The next day we had it towed to BMW dealership to run diagnostic scan on it. They told me it was an electrical issue and wanted $1100 up front to start trying to find out what it was. I had it towed home. So far i have found that the battery in the vehicle was the wrong size. Changed it to the correct size battery. I have also changed a few relays and checked most of the fuses. Still nothing works. Just the head lights, windshield wipers and dash lights. Has anyone else ever seen this???

Thanks Ahead of time
