Understanding the BL-ST-050 TPMS Sensor
The BL-ST-050 is a pre-programmed, clamp-in TPMS sensor manufactured by BH-Sens (Baolong Technology). It operates at 433MHz frequency and is designed as a direct replacement for OE parts 6608082005 and 8894215959. This sensor is explicitly listed for Geelygalaxy, Lynk&Co, and Zeekr vehicles—13 specific OE fitments in total.
If you own an EADO ET, the BL-ST-050 is not a guaranteed fit. The EADO ET typically uses a different TPMS system, often 315MHz sensors from Continental or Schrader. However, compatibility can vary by production year and region. Here’s how to verify.
Step-by-Step Fitment Verification Process
1. Check Your EADO ET’s Production Year and Region
The EADO ET (also marketed as Changan Eado EV in some markets) was produced from 2015 onward. TPMS systems changed over time:
- 2015-2018 models: Often used 315MHz direct sensors (clamp-in type).
- 2019-2023 models: Some later variants switched to 433MHz sensors, particularly in export markets.
Action: Locate the production date on your driver’s door jamb sticker or VIN decoder. If your car was manufactured for Europe, Middle East, or South America, it may share TPMS hardware with other Changan group vehicles.
2. Read the Existing Sensor’s Label
Remove a wheel and inspect the sensor mounted on the valve stem. You’re looking for:
- Frequency: Should be printed as “433MHz” or “315MHz”
- OE number: Often stamped as 6608082005 or 8894215959 on compatible sensors
- Brand: Look for markings like “BH-Sens”, “Baolong”, or “Continental”
- Type: Confirm it’s a clamp-in (metal valve stem with a hex nut) vs. snap-in (rubber stem)
If your existing sensor has “6608082005” or “8894215959” on it, the BL-ST-050 is a direct fit. If it shows a different number, it’s likely incompatible.
3. Compare Sensor Physical Dimensions
Even if the frequency matches, the sensor body must fit inside your wheel. Key measurements to check (from your old sensor or vehicle manual):
- Valve stem length: Should match your wheel’s design (short vs. long stem)
- Sensor body width: Must clear the brake caliper and wheel barrel
- Torque spec: Clamp-in sensors typically require 3.5-4.5 Nm (check your manual)
Pro tip: Remove one sensor and compare it side-by-side with the BL-ST-050 photos on the product page. Pay attention to the angle of the valve stem relative to the sensor body.
Fitment Compatibility Table for EADO ET Models
| Year Range | Region | Original Sensor Frequency | Original OE Number | BL-ST-050 Compatible? |
|---|---|---|---|---|
| 2015-2018 | China | 315MHz | 600-101-123 (varies) | No |
| 2015-2018 | Export (EU/ME) | 315MHz | 600-101-456 (varies) | No |
| 2019-2021 | China | 433MHz | 6608082005 (some) | Yes (verify) |
| 2019-2021 | Export | 433MHz | 8894215959 (some) | Yes (verify) |
| 2022-2023 | All | 433MHz | 6608082005 or 8894215959 | Yes (check type) |
Important: This table is a guide. Always verify with your specific sensor’s markings before purchasing.
Why the BL-ST-050 Might Work (and When It Won’t)
The BL-ST-050 is a Baolong Technology sensor. Baolong is a major OEM supplier for Chinese automotive brands, including some Changan group vehicles. If your EADO ET uses a Baolong-sourced TPMS system (common in export models after 2019), this sensor may be a direct swap.
However, Changan also uses Continental and Schrader sensors in some EADO ET variants. If your sensor is from these brands, the BL-ST-050 will not work—even if the frequency matches—because the programming protocol and data format differ.
How to Identify Your TPMS System Manufacturer
- Check the sensor body: Look for a logo or part number.
- Use a TPMS scan tool: Many shops can read the sensor ID and manufacturer code.
- Contact a dealer: Provide your VIN to get the exact OE part number.
Recommended Part for Verified Fitment
If your EADO ET’s existing sensor matches OE numbers 6608082005 or 8894215959, the BL-ST-050 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Geelygalaxy, Lynk&Co, Zeekr | OE# 6608082005, 8894215959 is an excellent replacement. It’s pre-programmed out of the box—no additional programming tool needed for most vehicles. Just install, drive a few minutes at 20+ mph, and the sensor auto-learns to your car’s system.
For EADO ET owners with different original sensors, consider purchasing a model-specific sensor from your local dealer or a custom-programmed unit from BH-Sens that matches your exact OE number.
Installation Tips for Clamp-In Sensors
- Always use a new metal valve stem and nut when replacing a clamp-in sensor.
- Torque the valve stem nut to 3.5-4.5 Nm (over-tightening can crack the sensor body).
- Balance the wheel after installation—sensor weight varies from the original.
- Reset the TPMS after replacement per your owner’s manual (usually a button press or drive cycle).
FAQ
Is the BL-ST-050 compatible with any EADO ET model?
Only if your EADO ET uses original sensors with OE numbers 6608082005 or 8894215959, typically found in some 2019-2023 export models. Always verify by inspecting your existing sensor.
Can I install the BL-ST-050 without reprogramming?
Yes, it’s pre-programmed to match those OE numbers. Most vehicles will auto-learn the new sensor after a short drive. If your car doesn’t, a TPMS tool may be needed to link the sensor ID.
What if my EADO ET uses a 315MHz sensor?
The BL-ST-050 operates only at 433MHz. A 315MHz system requires a different sensor. Do not attempt to install a mismatched frequency sensor—it will not communicate with your car’s receiver.
How do I know if my sensor is clamp-in or snap-in?
Clamp-in sensors have a metal valve stem with a visible hex nut above the wheel rim. Snap-in sensors have a rubber stem that pushes through the rim hole. The BL-ST-050 is clamp-in only.
