I found this when I was curious about my own C230:
"Believe it or not, jump starting a modern vehicle with several computers can cause a lot of problems. it can corrupt the software in 1 or more of the major computers. I know this because I was a lead diagnostic tech at major German and European Dealerships and Independent Shops. If you don't feel confident about the work being performed at the dealership, go to a MB owners forum online and find out ask who the best MB shop is in your area and who specializes in sophisticated electrical and computer trouble shooting. Excellent independent shops have the where with all to reprogram the computers with the HHT ( the MB diagnostic and reprogramming capable laptop ) Typically if a car has been jump started several times, ( many tow truck drivers are very behind the times in this area ) the computers need to be reprogrammed which can take many hours but should not require too many parts other than an over load relay or 2."
Hope you get it all worked out.
