DEF / AdBlue Heating Unit – Direct-Fit for 2010+ Sprinter & Mercedes Diesel Vans

9064700453 - qty 1

Keep your emissions system working smoothly with this genuine DEF/AdBlue heating unit — the critical component that prevents fluid freeze and ensures reliable Diesel Exhaust Fluid delivery for 2010-on Sprinter (NCV3) and other Mercedes diesel vans equipped with the deeper AdBlue tank. Overtime, cold weather or failing heaters can cause DEF to crystallize or clog, triggering system warnings, exhaust after-treatment faults, or even preventing proper NOₓ reduction.  This direct-fit heating unit replaces that risk — restoring dependable DEF flow, ensuring correct urea injection, and keeping your Emissions (SCR) system operational under any conditions. Built to OEM standard and compatible with the small-tank AdBlue setup (common in 2010-2014 Sprinter 2500/3500 with DEF systems), this unit installs directly — no modifications required. Whether you’re resolving a DEF-system fault or preemptively ensuring emissions compliance, this heating unit is a must-have for reliable, long-term performance.
