#1 you don,t need a MB dealer. we have a older unit like yours a 2007 and love it. listen real good windows down head out find which side is the problem ,thats half the battle. one thing thats a puzzle you here the noise sitting still that don,t sound like brakes . do it yourself or find a brake shop who works on trucks . you don,t want CW or any rv dealer .get on google and ask, a;so the sprinter club could help . my front caliper went bad at 30k ,but that makes a nasty sound you can,t miss.got the new set of shoes both sides new caliper new rotor installed in a fair grounds field for $300. bucks. parts came from a napa dealer.
