Most dealers won't "deprogram" your DRLs (even though they can,) as well as turn down your EGR and other things that would make sense but are frowned upon by the EPA or other federal agencies. In the case of my VW, the dealer won't do it, but if you can find a local VW "guru" who's equipped with a VAG-COM diagnostic tool/programmer, you might be in luck. In the case of the MB Sprinter chassis, your best bet may be to find an online forum (like the Forest River one) that's dedicated to the Sprinter chassis (MB or Dodge) and see if there's someone in your area that is willing and able to do what you want.
