Diesel Pro in Glen Rock PA...... Just a few miles over the Maryland line in Pennsylvania.
http://mydieselpro.com/I have not had my Jeep there yet but I have talked to them about working on mine for things I can't do on my own, like timing belt. They do work on VW TDi and Sprinter. They told me they knew and had worked on VM Motori engines but never in vehicles before since other then our CRD there aren't any in vehicles.
The idea that they have not work on a CRD is maybe not so good but they have seen VM engines used in industry or other things in the shop and do work on TDI and Sprinter. A few guys on here think that if you find a shop that works on Sprinters they are close enough to ours that you should be in good hands. I am going to use Diesel Pro myself when needed.
If you get them to do any work for you post back with how you liked the place.
