Original AdBlue / SCR Fluid Tank with Pumping Module (Pump) and Heater – 2K5131877C / 5Q0131969C

Complete factory SCR (Selective Catalytic Reduction) exhaust gas emission reduction system assembly – contoured AdBlue fluid tank with integrated supply module: electric pumping pump, ceramic heating element (heater) and urea 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 diesel engines 2.0 TDI with Twindosing technology (dual AdBlue injection), based on the modular platform MQB Evo.

Volkswagen Group OE component set responsible for storing and pressure-feeding the aqueous urea solution (AUS 32 / AdBlue) to the injector in the exhaust system. The tank marked with index C represents an updated factory revision of the plastic component with increased resistance to urea crystallization and thermal stress. The integrated pumping module 5Q0131969C prevents the fluid from freezing at negative temperatures (below -11°C), maintains constant operating pressure in the line and transmits operating parameters to the ECU engine controller.

Vehicle applications:

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 units (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 all-wheel drive variants)

(Note: The 2K5 profile tank is designed exclusively for the Caddy V body on the MQB Evo platform. It is not compatible with Caddy IV 2K/SA models due to different mounting point and connector architectures).

Installation requirements:

• Hydraulic connection to the factory quick couplings of the heated SCR lines.

• After installation in the vehicle and refilling with fresh AdBlue fluid, the pump module and level sensors must be adapted using a diagnostic tester (ODIS / VCDS), and the SCR system bleeding and pressure test procedure must be performed.
