Why the EQB Needs a Specific TPMS Sensor
The EQB uses a direct TPMS system, meaning each wheel has a sensor that transmits pressure and temperature data to the car’s ECU. Unlike indirect systems that rely on wheel speed sensors, the EQB’s system requires a compatible 433MHz or 315MHz sensor (depending on market and year). The BH-Sens BL-ST-081 covers OE numbers 36106872774, 42607WAA02, 5A3DC0401, and several others, including Mercedes-Benz’s A0009052102 and A0009054104. That makes it a solid candidate for most EQB models from 2022 onward.
What to Check Before Ordering a TPMS Sensor for Your EQB
Frequency Compatibility
Most EQB vehicles sold in North America and Europe after 2022 use 433MHz sensors. However, some early 2022 EQB 300 and EQB 350 units in North America shipped with 315MHz sensors. Check your original sensor’s frequency before ordering. If you remove a wheel and see “433MHz” stamped on the metal housing, you’re good with the BL-ST-081. If you see “315MHz,” look for a BH-Sens 315MHz variant.
Valve Type: Clamp-in vs. Snap-in
The BL-ST-081 is a clamp-in sensor, which uses a metal valve stem secured by a nut from inside the wheel. This is the standard on the EQB. Snap-in sensors (rubber valve) are not compatible—you’ll get leaks and false low-pressure warnings.
OE Number Cross-Reference
Here’s a quick fitment table for the BL-ST-081:
| OE Number | Compatible EQB Models | Notes |
|---|---|---|
| 36106872774 | EQB 300, EQB 350 (2022–2024) | Most common for North America |
| A0009052102 | EQB 250, EQB 300 (Europe) | Also fits some late-2021 models |
| 42607WAA02 | EQB 350 (2023–2024) | Honda/BMW cross-fit, but works on EQB |
| 5A3DC0401 | EQB 300 (2022–2023) | Fits with OEM pre-programmed setting |
Always verify against your vehicle’s VIN or the original sensor part number before purchasing.
B2B Bulk Buying Notes for EQB TPMS Sensors
If you’re sourcing for a fleet of EQB vehicles or a repair shop, here’s what matters:
Batch Consistency
Order from a single production batch. BH-Sens (Baolong Technology) sensors from different batches may have slight firmware variations that affect learn-in behavior. Request batch numbers from your supplier and test a sample before committing to a large order.
Pre-programmed vs. Programmable
The BL-ST-081 is offered as a pre-programmed sensor, meaning it’s locked to specific OE numbers. For bulk orders, confirm that the sensors are pre-programmed to the OE numbers your EQB fleet uses (e.g., 36106872774). Programmable sensors add flexibility but require a TPMS programming tool—factor that into your labor cost.
Packaging and Warranty
B2B orders should include individual packaging to prevent damage during shipping. BH-Sens typically offers a 2-year or 30,000-mile warranty. Verify this with your supplier, and ensure you get a Certificate of Conformance for audit purposes.
Recommended Part for Your EQB

It covers the most common OE numbers, uses a clamp-in design, and is pre-programmed to save you programming time.
FAQ
Can I use a BL-ST-081 sensor on a 2021 Mercedes-Benz EQB?
The EQB wasn’t launched until late 2021 in Europe and early 2022 in North America. If your vehicle is a 2021 EQB (Euro-spec), it likely uses 433MHz and OE number A0009052102, so the BL-ST-081 fits. Check the frequency first.
Do I need to reprogram the BL-ST-081 after installation?
No. The BL-ST-081 is pre-programmed to match OE numbers like 36106872774. It will automatically pair with your EQB’s TPMS receiver during the learn-in procedure. In most cases, you just drive above 15 mph for 10 minutes, and the sensors sync.
What if my EQB shows a TPMS error after installing a BL-ST-081 sensor?
First, double-check that the sensor frequency matches your vehicle (433MHz vs. 315MHz). If it matches, the error is usually due to a loose clamp nut—torque the nut to 35–40 in-lbs (check your manual). If the error persists, re-run the TPMS relearn procedure using a TPMS tool or the car’s menu.
Is BH-Sens a reliable brand for aftermarket TPMS?
Yes. BH-Sens is manufactured by Baolong Technology, one of the largest OE TPMS suppliers in China. They supply sensors to brands like BMW, Mercedes-Benz, and Mini. The BL-ST-081 meets OE specs for pressure range (0–87 psi) and temperature tolerance (-40°C to 125°C).
