There are Sprinter Vans that come from the factory with a shallower door clearance for the slider. We have only seen this on vans purchased outside of the US. This rare occurrence will cause the slider to contact the passenger side flare. This is remedied by installing the more common slider mechanism for the door that pulls it further away from the van exterior. Please use the part numbers below as a reference and contact your local Mercedes OEM parts dealer with your vin number to confirm the part needed for your van.
