Look up Diesel Injection Service in your phone book. Or call some independent shops in you area and ask them who they use. Any injection service will also work on turbos -- the only reason for asking for recommendations is that some are better or more familiar with MB turbos that other.

You don't need anything else done, right? Just a weak spring? This won't be any 600 bucks!
