Product Description

This urea (adblue) dosing module is designed as a direct-fit replacement for FORD Focus IV. 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: 0 444 021 092. It also cross-references to OE/aftermarket numbers including 2249375, KV615J281A, KV615J281AA, KV615J281AB, 9823743580, 3554051 and 1 more. 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 workshops, parts distributors and vehicle owners a quality-assured alternative to OEM pricing for scheduled SCR system maintenance and repair.

BG 205049 (OE 0 444 021 092): function on the vehicle

Urea (AdBlue) Dosing Module for FORD Focus IV – OE 0 444 021 092 is supplied by BEST GROWTH under part number 205049, cross-referenced to OE 0 444 021 092, 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 205049 is built to the position defined by its OE application in passenger car service on the platform from Ford. 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 Ford and OE cross reference

BG 205049 replaces 8 OE references: 0 444 021 092, 2249375, KV615J281A, KV615J281AA, KV615J281AB, 9823743580, 3554051 and MT76-5J281-AA. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205049 includes Ford, typically on FORD Focus IV. Coverage lists are a starting point for identification, not a substitute for checking the OE number on the vehicle.

Where several OE numbers appear against one BG reference, they are supersessions or regional variants of the same specification. Ordering by 0 444 021 092 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 0 444 021 092

These complaints bring a vehicle in with the Ford def dosing modules under suspicion. None of them prove BG 205049 has failed on its own, which is why the checks below matter before a replacement is ordered.

deposits inside the mixer restricting exhaust flow
white urea crystallisation around the dosing point or mixer
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

Checks before fitting BG 205049

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 205049

BG 205049 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.

Send OE 0 444 021 092 or the number printed on your part, the engine code and the vehicle identification number with your enquiry, and our technical team will confirm the correct reference, current stock position and lead time before you commit to an order.
