Does BG 205091 replace OE 2095566?

Yes. BG 205091 is listed against 2095566, 2238324, 2238325, 2722701 and 1302550. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 205091 fit?

Recorded coverage includes Scania. 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 205091.

Product Description

This urea (adblue) dosing module is designed as a direct-fit replacement for Scania Truck P/G/R/S Series. 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: 2095566. It also cross-references to OE/aftermarket numbers including 2238324, 2238325, 2722701, 1302550. 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.

Vehicle manufacturer names, logos and OE reference numbers are used for identification and compatibility purposes only. BEST GROWTH products are independent aftermarket products and are not manufactured, sponsored or endorsed by the respective vehicle manufacturers.

BG 205091 (OE 2095566): function on the vehicle

Urea (AdBlue) Dosing Module for Scania Truck P/G/R/S Series – OE 2095566 is supplied by BEST GROWTH under part number 205091, cross-referenced to OE 2095566, 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 205091 is built to the position defined by its OE application in truck service on the platform from Scania. 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 Scania and OE cross reference

BG 205091 replaces 5 OE references: 2095566, 2238324, 2238325, 2722701 and 1302550. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205091 includes Scania, typically on Scania Truck P/G/R/S Series. 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 2095566 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 2095566

These complaints bring a vehicle in with the Scania def dosing modules under suspicion. None of them prove BG 205091 has failed on its own, which is why the checks below matter before a replacement is ordered.

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
white urea crystallisation around the dosing point or mixer

Checks before fitting BG 205091

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

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

Quality, packaging and ordering 205091

BG 205091 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 2095566 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.
