Urea (AdBlue) Dosing Module for Hyundai KONA/SANTA FE/TUCSON/i30/i40 CRDi KIA GENESIS Genesis GV70/GV80 CRDi AWD – OE 0444021060

BG 205034 (OE 0444021060): function on the vehicle

Urea (AdBlue) Dosing Module for Hyundai KONA/SANTA FE/TUCSON/i30/i40 CRDi KIA GENESIS Genesis GV70/GV80 CRDi AWD – OE 0444021060 is supplied by BEST GROWTH under part number 205034, cross-referenced to OE 0444021060, 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 205034 is built to the position defined by its OE application in passenger car service on platforms from Hyundai, Kia and Genesis. 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 Hyundai, Kia and Genesis and OE cross reference

BG 205034 replaces 11 OE references: 0444021060, 020444021060-02, C00066128, 0444021076-01, 0444021088, 0280158712, MT76-5J281-AA, 2466742, 296302U000 and 571014110250. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205034 includes Hyundai, Kia and Genesis, typically on Hyundai KONA/SANTA FE/TUCSON/i30/i40 CRDi KIA GENESIS Genesis GV70/GV80 CRDi AWD. 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 0444021060 and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 0444021060

These complaints bring a vehicle in with the Hyundai and Kia def dosing modules under suspicion. None of them prove BG 205034 has failed on its own, which is why the checks below matter before a replacement is ordered.

• 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
• coolant or DEF weeping at the module interface
• audible ticking absent during a commanded dose

Checks before fitting BG 205034

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 205034

BG 205034 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 0444021060 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.
