Does BG 201354 replace OE 04L907805G?

Yes. BG 201354 is listed against 04L907805G and 5WK97226. Confirm the number printed on the removed part and any manufacturer supersession before ordering.

Which vehicles does BG 201354 fit?

Recorded coverage includes Volkswagen. It is supplied as a direct-fit aftermarket nox sensors on 12V systems. Adaptation, reset or relearn procedures required by the vehicle manufacturer still apply after installation.

Does this fault code always mean the nox sensors 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 201354.

Product Description

This BG NOx (nitrogen oxide) sensor is designed for the urea/AdBlue-based SCR (Selective Catalytic Reduction) emissions system on VW Transporter T5 / T6 / T6.1. It is a direct-fit replacement for OE reference 04L907805G / cross reference 5WK97226. Rated for 12V electrical systems. The sensor provides accurate real-time NOx measurement for precise urea dosing control, helping maintain stable SCR performance and compliance with diesel emission standards.

BG 201354 (OE 04L907805G): function on the vehicle

NOx Sensor 04L907805G is supplied by BEST GROWTH under part number 201354, cross-referenced to OE 04L907805G, as a direct-fit aftermarket nox sensors. In service it runs a heated zirconia measuring cell inside its own sensor control module, converts the raw cell current into a NOx value in ppm, and publishes it on the bus. The engine controller cannot calculate dosing quantity or conversion efficiency without a plausible signal from it.

BG 201354 is built to the position defined by its OE application on a 12V electrical system on the platform from Volkswagen. Position, calibration and connector layout are part of the specification, so a part that physically fits is not automatically the correct part.

Fitting position matters as much as the part number: upstream and downstream references often share a housing but carry different calibration data and cable lengths.

Fitment for Volkswagen and OE cross reference

BG 201354 replaces 2 OE references: 04L907805G and 5WK97226, covering cross applications. Always confirm the number printed on the removed part, including any supersession issued by the vehicle manufacturer.

Recorded vehicle coverage for 201354 includes Volkswagen, typically on Transporter T5 / T6 / T6.1. 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 04L907805G and quoting the number on your part lets our technical team confirm the variant before despatch.

Symptoms that lead to replacing 04L907805G

These complaints bring a vehicle in with the Volkswagen nox sensors under suspicion. None of them prove BG 201354 has failed on its own, which is why the checks below matter before a replacement is ordered.

SCR efficiency below threshold or NOx-signal-implausible fault codes
DEF over-consumption with no visible leak
torque derate or speed inducement with a full, in-spec DEF tank
no communication with the sensor control module after a cold start
sensor value frozen at a fixed number once the exhaust warms up

Checks before fitting BG 201354

Aftertreatment faults are usually system faults. Working through these checks prevents a repeat failure after the new nox sensors is fitted.

Verify DEF concentration with a refractometer before blaming the measuring cell.
Check for a pending software or parameter update for the sensor control module on that platform.
After fitting, run the manufacturer's adaptation or relearn so stored efficiency counters reset.
Compare upstream and downstream NOx readings warmed and under load — idle values prove nothing.
Confirm supply voltage, ground quality and bus termination before condemning the sensor module.

Quality, packaging and ordering 201354

BG 201354 is manufactured and tested to aftermarket replacement standards, with electrical, leakage and functional testing carried out before packing on the 12V specification. Bulk and retail packaging, private-label cartons and customer-specific labelling are available for distributors and workshop groups.

Send OE 04L907805G 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.
