I need to check transmission codes in this '98 E320 with DAS3. It uses the round connector in the engine bay. It doesn't work through the underdash OBD port. The closest kind person I know is 50 miles away which is a difficult trek for this sick puppy. Is there someone closer? Please PM if you can help. Name your price!

Thanks,
Sixto
