Which vehicles does BG 205008 fit?

Recorded coverage includes Mercedes-Benz. 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 205008.

Product Description

This urea (adblue) dosing module is designed as a direct-fit replacement for Mercedes-Benz Actros / Arocs / Antos / Atego. 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: A000 140 01 39. It also cross-references to OE/aftermarket numbers including A000 140 02 39, A000 140 05 39, A000 140 07 39, A000 140 41 39. 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 205008 (OE A000 140 01 39): function on the vehicle

Urea (AdBlue) Dosing Module for Mercedes-Benz Actros / Arocs / Antos / Atego – OE A000 140 01 39 is supplied by BEST GROWTH under part number 205008, cross-referenced to OE A000 140 01 39, 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 205008 is built to the position defined by its OE application in truck service on the platform from Mercedes-Benz. 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 Mercedes-Benz and OE cross reference

BG 205008 replaces 5 OE references: A000 140 01 39, A000 140 02 39, A000 140 05 39, A000 140 07 39 and A000 140 41 39. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205008 includes Mercedes-Benz, typically on Mercedes-Benz Actros / Arocs / Antos / Atego. 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 A000 140 01 39 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing A000 140 01 39

These complaints bring a vehicle in with the Mercedes-Benz def dosing modules under suspicion. None of them prove BG 205008 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 205008

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

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.
Review exhaust temperature history — cold-side dosing wets the wall and forms deposits.

Quality, packaging and ordering 205008

BG 205008 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 A000 140 01 39 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.
