Diesel Exhaust Fluid / Adblue
With 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 start countdown before you are locked out from driving your Sprinter van.
Never allow your DEF AdBlue system to run low for long as the pump and heater seem to fail when the fluid runs low, and never add anything but DEF to the system.
We also offer Malone Tuning systems to eliminate failures and improve reliability for off road use.
