Yes. BG 205770 is listed against 0 280 158 714, 0 280 158 701 and 0 280 158 705. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 205770 fit?

Recorded coverage includes Bosch. 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 205770.

Product Description

This urea (adblue) dosing module is designed as a direct-fit replacement for Universal — Multiple Brands (Truck / Bus / Off-road). 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: 0 280 158 714. It also cross-references to OE/aftermarket numbers including 0 280 158 701, 0 280 158 705. 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 205770 (OE 0 280 158 714): function on the vehicle

Urea (AdBlue) Dosing Module for Universal — Multiple Brands (Truck / Bus / Off-road) – OE 0 280 158 714 is supplied by BEST GROWTH under part number 205770, cross-referenced to OE 0 280 158 714, 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 205770 is built to the position defined by its OE application in truck, bus and construction equipment service on the platform from Bosch. 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 Bosch and OE cross reference

BG 205770 replaces 3 OE references: 0 280 158 714, 0 280 158 701 and 0 280 158 705. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205770 includes Bosch, typically on Universal — Multiple Brands (Truck / Bus / Off-road). 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 0 280 158 714 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 0 280 158 714

These complaints bring a vehicle in with the Bosch def dosing modules under suspicion. None of them prove BG 205770 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 205770

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

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.
Confirm the purge cycle completes at shutdown; skipped purges cause freeze damage.

Quality, packaging and ordering 205770

BG 205770 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 0 280 158 714 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.
