I have posted on this topic before. It appears your problem might be the conflict between the emissions and main engine computers. They both need to be replaced. However, they are expensive, so like others have suggested, you need to take it to a MB dealer that specializes in sprinters and plead your case. Their should be internal TSB's (technical service bulletins) on this issue. AND for that reason, you need the latest information, which probably is accessible the easiest from a MB dealer. Just sayin'
