Urea (AdBlue) Dosing Module for Chevrolet Cruze Diesel – OE EM1213IJ

BG 205066 (OE EM1213IJ): function on the vehicle

Urea (AdBlue) Dosing Module for Chevrolet Cruze Diesel – OE EM1213IJ is supplied by BEST GROWTH under part number 205066, cross-referenced to OE EM1213IJ, 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 205066 is built to the position defined by its OE application in passenger car service on the platform from Chevrolet. 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 Chevrolet and OE cross reference

BG 205066 replaces 4 OE references: EM1213IJ, 0444021036, 904531 and 12656061. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 205066 includes Chevrolet, typically on Chevrolet Cruze Diesel. 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 EM1213IJ and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing EM1213IJ

These complaints bring a vehicle in with the Chevrolet def dosing modules under suspicion. None of them prove BG 205066 has failed on its own, which is why the checks below matter before a replacement is ordered.

• 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
• coolant or DEF weeping at the module interface

Checks before fitting BG 205066

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

• 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.
• Check the cooling circuit or heat shield is intact before fitting a replacement.

Quality, packaging and ordering 205066

BG 205066 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 EM1213IJ 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.

Which vehicles does BG 205066 fit?

Recorded coverage includes Chevrolet. 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 205066.
