Urea (AdBlue) Dosing Module for Iveco Daily / EuroCargo – OE 5802540776

BG 205018 (OE 5802540776): function on the vehicle

Urea (AdBlue) Dosing Module for Iveco Daily / EuroCargo – OE 5802540776 is supplied by BEST GROWTH under part number 205018, cross-referenced to OE 5802540776, as a direct-fit aftermarket def dosing modules. In service it atomizes diesel exhaust fluid into the exhaust stream ahead of the SCR catalyst. Spray quality, dosing quantity and purge behaviour decide whether urea converts to ammonia or builds solid deposits.

BG 205018 is built to the position defined by its OE application in truck and light commercial vehicle service on the platform from IVECO. 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 IVECO and OE cross reference

BG 205018 replaces 1 OE reference: 5802540776. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205018 includes IVECO, typically on Iveco Daily|EuroCargo. 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 5802540776

These complaints bring a vehicle in with the IVECO def dosing modules under suspicion. None of them prove BG 205018 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 205018

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.
