Original AdBlue / SCR Fluid Tank with Delivery Module (Pump) and Heater – 2K5131877A / 5Q0131969C

Complete factory SCR (Selective Catalytic Reduction) emission reduction system module – AdBlue fluid tank with integrated supply module: pressure pump, heating element (heater) and fluid level and temperature sensor (Harnstoffbehälter mit Fördereinheit und Heizelement / AdBlue Urea Tank with Pump and Heater Unit), designed for Volkswagen Caddy V / Caddy California / Caddy Cargo / Maxi (type SB / SBB / SBJ) manufactured from model year 2020 to 2026+, equipped with new generation diesel engines 2.0 TDI with Twindosing technology (dual AdBlue injection), based on the modular platform MQB Evo.

Volkswagen Group OE component assembly optimized for precise dosing of aqueous urea solution (AUS 32 / AdBlue) into the exhaust system to neutralize nitrogen oxides ($NO_x$). The set includes a profiled plastic tank with high chemical resistance mounted in the chassis and the delivery module (electric pump) embedded in it with a ceramic heating element preventing the fluid from freezing at temperatures below -11°C, hydraulic ports for quick couplings and an integrated multi-pin electrical socket.

Vehicle application:

Volkswagen:

• Caddy V Van / Cargo (type SBB) – 2.0 TDI engines (from 2020 to 2026+)

• Caddy V Estate / MPV (type SBJ) – 2.0 TDI engines (from 2020 to 2026+)

• Caddy V Maxi Cargo / Estate (type SBB / SBJ) – 2.0 TDI engines (from 2020 to 2026+)

• Caddy V California (type SBJ) – 2.0 TDI engines (from 2020 to 2026+)

Dedicated 2.0 TDI engine codes (EA288 Evo / Twindosing generation):

• 2.0 TDI 75 hp (55 kW): DTRF

• 2.0 TDI 102 hp (75 kW): DTRD

• 2.0 TDI 122 hp (90 kW): DTRE / DTRC (including 4MOTION versions)

(Note: The set is designed for the MQB Evo platform of the Caddy V model. It is not suitable for the older Caddy IV generation type 2K / SA due to the different chassis recess shape and different pump connector architecture).

Installation requirements:

• Hydraulic connection is performed using the factory quick couplings of the heated SCR lines.

• After installation and filling the system with fresh AdBlue fluid, it is required to perform the bleeding and pump/tank adaptation procedure using a diagnostic tester (ODIS / VCDS) and clear any SCR range calculation errors.
