BG 205012-1 (OE 0444011025): function on the vehicle
Urea (AdBlue) Dosing Module for MAN TGL / TGM / TGS / TGX DAF CF / XF Truck – OE 0444011025 is supplied by BEST GROWTH under part number 205012-1, cross-referenced to OE 0444011025, 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 205012-1 is built to the position defined by its OE application in truck service on platforms from Bosch, MAN and DAF. 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 Bosch, MAN and DAF and OE cross reference
BG 205012-1 replaces 1 OE reference: 0444011025. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.
Recorded vehicle coverage for 205012-1 includes Bosch, MAN and DAF, typically on MAN TGL / TGM / TGS / TGX DAF CF / XF Truck. 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 0444011025
These complaints bring a vehicle in with the Bosch and MAN def dosing modules under suspicion. None of them prove BG 205012-1 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 205012-1
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.

BG 205012-1 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.
