Does BG 205040 replace OE 1205108XPW01A?

Yes. BG 205040 is listed against 1205108XPW01A. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 205040 fit?

Recorded coverage includes Great wall. 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 205040.

Product Description

This urea injection nozzle is designed as a direct-fit replacement for Great Wall National VI Urea Nozzle. 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: 1205108XPW01A. 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 205040 (OE 1205108XPW01A): function on the vehicle

Urea Injection Nozzle for Great Wall National VI Urea Nozzle – OE 1205108XPW01A is supplied by BEST GROWTH under part number 205040, cross-referenced to OE 1205108XPW01A, as a direct-fit aftermarket def dosing modules. In service it meters DEF under pump pressure through a solenoid injector into the hot exhaust pipe, with a cooling circuit or heat shield keeping the injector body below its thermal limit between doses.

BG 205040 is built to the position defined by its OE application on the platform from Great wall. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

A dosing module rarely fails alone. Deposits are usually evidence of a temperature or mixing problem that will destroy the replacement unless it is corrected.

Fitment for Great wall and OE cross reference

BG 205040 replaces 1 OE reference: 1205108XPW01A. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205040 includes Great wall, typically on Great Wall National VI Urea Nozzle. 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 1205108XPW01A

These complaints bring a vehicle in with the Great wall def dosing modules under suspicion. None of them prove BG 205040 has failed on its own, which is why the checks below matter before a replacement is ordered.

audible ticking absent during a commanded dose
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

Checks before fitting BG 205040

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

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.
Run a quantity test and inspect the spray pattern rather than judging the injector by appearance.

Quality, packaging and ordering 205040

BG 205040 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.
