BG 205076 (OE 93457779): function on the vehicle
Urea (AdBlue) Dosing Module for Nissan NV300 / NV400 Opel Movano B / Vivaro B Renault Master / Trafic /... – OE 93457779 is supplied by BEST GROWTH under part number 205076, cross-referenced to OE 93457779, 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 205076 is built to the position defined by its OE application in light commercial vehicle and passenger car service on platforms from Renault, Nissan and Opel. 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 Renault, Nissan and Opel and OE cross reference
BG 205076 replaces 6 OE references: 93457779, 95520919, 0 444 021 045, 6000616939, 208S400Q0A and 93457779. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.
Recorded vehicle coverage for 205076 includes Renault, Nissan and Opel, typically on Nissan NV300 / NV400 Opel Movano B / Vivaro B Renault Master / Trafic / Megane / Talisman. 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 93457779 and quoting the number on your part lets our technical team confirm the variant before despatch.
Symptoms that lead to replacing 93457779
These complaints bring a vehicle in with the Renault and Nissan def dosing modules under suspicion. None of them prove BG 205076 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 205076
Aftertreatment faults are usually system faults. Working through these checks prevents a repeat failure after the new def dosing modules is fitted.
- 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.
- Verify commanded versus actual dosing pressure during an active dose, not at rest.
Quality, packaging and ordering 205076
BG 205076 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.
