Does BG 205114 replace OE 22588471?

Yes. BG 205114 is listed against 22588471. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 205114 fit?

Recorded coverage includes Volvo. It is supplied as a direct-fit aftermarket def dosing modules. Adaptation, reset or relearn procedures required by the vehicle manufacturer still apply after installation.

Does this fault code always mean the def dosing modules has failed?

No. Exhaust leaks, wiring and connector damage, reductant quality, dosing performance and upstream engine faults can all produce the same codes. Validate those inputs before replacing BG 205114.

Product Description

This urea (adblue) dosing module is designed as a direct-fit replacement for Volvo FH / FM / FMX Truck. It meters precise doses of AdBlue / Diesel Exhaust Fluid (DEF) into the exhaust stream as part of the vehicle's Selective Catalytic Reduction (SCR) aftertreatment system, converting NOx emissions into harmless nitrogen and water vapor to help the engine meet its emission standard. Primary OE reference number: 22588471. Manufactured by BG Brand (Wenzhou Best Growth IE Co., Ltd.) to OE-equivalent fit, form and function, this part is tested for reliable sealing and dosing accuracy, offering fleets, workshops and parts distributors a quality-assured alternative to OEM pricing for scheduled SCR system maintenance and repair.

BG 205114 (OE 22588471): function on the vehicle

Urea (AdBlue) Dosing Module for Volvo FH / FM / FMX Truck – OE 22588471 is supplied by BEST GROWTH under part number 205114, cross-referenced to OE 22588471, as a direct-fit aftermarket def dosing modules. In service it is the final actuator of the SCR loop: whatever the controller calculates from the NOx signal is only delivered as accurately as this module sprays it.

BG 205114 is built to the position defined by its OE application in truck service on the platform from Volvo. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Seal and gasket condition at the exhaust interface is part of the repair: a leaking joint cools the spray zone and promotes crystallisation.

Fitment for Volvo and OE cross reference

BG 205114 replaces 1 OE reference: 22588471. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205114 includes Volvo, typically on Volvo FH / FM / FMX Truck. Coverage lists are a starting point for identification, not a substitute for checking the OE number on the vehicle.

Quote the number printed on your part with the engine code when you enquire; a single-reference part is the most common source of ordering errors when a platform received a mid-life update.

Symptoms that lead to replacing 22588471

These complaints bring a vehicle in with the Volvo def dosing modules under suspicion. None of them prove BG 205114 has failed on its own, which is why the checks below matter before a replacement is ordered.

low dosing pressure or pressure-build-up fault codes
SCR low-conversion codes with confirmed in-spec DEF
coolant or DEF weeping at the module interface
audible ticking absent during a commanded dose
deposits inside the mixer restricting exhaust flow

Checks before fitting BG 205114

Aftertreatment faults are usually system faults. Working through these checks prevents a repeat failure after the new def dosing modules is fitted.

Confirm the purge cycle completes at shutdown; skipped purges cause freeze damage.
Review exhaust temperature history — cold-side dosing wets the wall and forms deposits.
Check the cooling circuit or heat shield is intact before fitting a replacement.
Clean or replace the mixer if crystallisation is already established, or the new module will block too.
Verify commanded versus actual dosing pressure during an active dose, not at rest.

Quality, packaging and ordering 205114

BG 205114 is manufactured and tested to aftermarket replacement standards, with electrical, leakage and functional testing carried out before packing. Bulk and retail packaging, private-label cartons and customer-specific labelling are available for distributors and workshop groups.
