DEFWith the advent of tougher emissions standards, came the AdBlue DEF system on Mercedes Sprinter vans, and a whole new challenge to the owner has been added.

DEF is used along with Selective Catalytic Reaction SCR to lower emissions of Oxides of Nitrogen NOx.

The AdBlue system has a tank, pump, warmer, injection system and a NOx sensor.  Everyone of those parts has been known to fail, and we not only know how to repair them, we know how to diagnose and test the system, as well as reset the countdown of starts left before you are locked out from driving your Sprinter van.

Never allow your DEF AdBlue system to runn low for long as the pump and heater seem to fail when the fluid runs low. Stop by and see us  or give us a call with any concerns you may have.
