Understanding the BL-ST-085 TPMS Sensor
The BL-ST-085 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Leapmotor | OE# 8083010BA01 is a clamp-in, pre-programmed TPMS sensor manufactured by BH-Sens, which is the aftermarket brand of Baolong Technology — one of the original equipment (OE) suppliers for many Chinese auto manufacturers, including Leapmotor. Operating at 433MHz, this sensor is designed to match the frequency and protocol used by Leapmotor’s onboard TPMS system.
Key specs:
- Frequency: 433MHz
- OE Number: 8083010BA01
- Type: Clamp-in (metal valve stem)
- Pre-programmed: Yes — no cloning or programming tool required for most applications
- Compatible Brands: Leapmotor only (not interchangeable with other brands without modification)
Which Leapmotor Models Does It Fit?
This sensor is confirmed for seven dedicated Leapmotor vehicle applications. The exact model names and approximate year ranges are listed below. Always cross-check with your vehicle’s specific production date, as mid-year changes can occur.
| Leapmotor Model | Compatible Year Range (Approximate) | Notes |
|---|---|---|
| T03 | 2020–2024 | All trims |
| C11 | 2021–2024 | Both RWD and AWD variants |
| C01 | 2022–2024 | All trims |
| S01 | 2019–2022 | Early production may differ |
| C16 | 2023–2024 | Newer model |
| B01 | 2022–2024 | Commercial variant |
| A11 | 2021–2023 | Older model, verify carefully |

How to Verify Fitment Before Buying
Step 1: Locate Your Original Sensor Part Number
The most reliable method is to remove one wheel and read the part number printed on your existing TPMS sensor. For Leapmotor vehicles, the OE number is typically 8083010BA01. If your sensor shows a different number (e.g., 8083010BA02), the BL-ST-085 may still work if the frequency and protocol match — but confirm with a parts specialist.
Step 2: Check Your Vehicle’s Production Date
Leapmotor sometimes updates TPMS components mid-year. Look on the driver’s door jamb sticker for the “Date of Manufacture.” Compare this with the year ranges in Table 1. For example, a T03 built in late 2024 should be fine, but a 2019 T03 might use a different sensor.
Step 3: Use Your VIN
Contact the seller (such as risensauto.com) with your 17-digit VIN. They can cross-reference the VIN against Leapmotor’s parts database to confirm compatibility. This is the safest approach, especially for older models like the S01 or A11.
Step 4: Verify the Frequency
This sensor operates at 433MHz. Most Leapmotor TPMS systems use 433MHz, but some early S01 models (2019) may use 315MHz. If you’re unsure, a cheap frequency tester or a call to a Leapmotor dealer can clarify.
Pre-Programmed vs. Programmable: What This Means for You
The BL-ST-085 is pre-programmed. That means it comes from the factory with the correct ID and protocol for Leapmotor’s system. When installed, the vehicle’s TPMS module should recognize the sensor automatically after a short drive (usually 10–20 minutes above 15 mph). No separate programming tool is needed.
Compare this to programmable sensors (like Autel MX-sensors), which require a tool to write the vehicle-specific data. Pre-programmed sensors simplify the job for DIY installers — just mount, install, and drive.
Installation Tips for Leapmotor Owners
- Torque the valve stem to spec: Most clamp-in sensors require 4–5 Nm (35–44 in-lbs) on the nut. Over-tightening can crack the sensor housing. Check your vehicle manual for the exact value.
- Relearn procedure: After installation, drive the car for 10–15 minutes at a steady speed. If the TPMS warning light doesn’t go out, a manual relearn may be needed. For Leapmotor models, this usually involves pressing a button under the dash or using a TPMS trigger tool. Refer to your owner’s manual.
- Replace all four sensors at once: TPMS sensors have a battery life of 5–7 years. If one fails, the others are likely close behind. Replacing all four saves labor and prevents repeated warning lights.
Common Compatibility Mistakes
- Assuming all 433MHz sensors are interchangeable. They are not. Each manufacturer uses a unique communication protocol. A 433MHz sensor made for Toyota will not work on a Leapmotor.
- Using a sensor from a different Baolong part number. BH-Sens makes many sensors. Only the 8083010BA01 variant (BL-ST-085) is designed for Leapmotor. Other Baolong sensors (e.g., BL-ST-086) target different brands.
- Ignoring production year splits. Leapmotor may have changed suppliers between model years. A 2022 C11 might use a different sensor than a 2023 C11, even if the body style looks identical.
Recommended Part
For a direct fit replacement on your Leapmotor, use the BL-ST-085 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Leapmotor | OE# 8083010BA01. It’s pre-programmed, clamp-in, and matches the OE specification. Always verify your vehicle’s production year and original part number before ordering.
FAQ
Can I install the BL-ST-085 myself without a TPMS tool?
Yes, because it is pre-programmed. Mount the sensor, install the wheel, and drive for 10–15 minutes. The vehicle should automatically recognize the new sensor. If the warning light stays on, a manual relearn may be required — check your owner’s manual for the specific procedure.
Will this sensor work on a Leapmotor S01 from 2019?
Possibly, but only if your S01 uses 433MHz frequency and the 8083010BA01 part number. Some early 2019 S01 models used 315MHz sensors. Check the original sensor number or contact the seller with your VIN for confirmation.
How long does the battery last in the BL-ST-085?
The built-in battery typically lasts 5–7 years under normal driving conditions. The sensor is sealed and non-replaceable — once the battery dies, replace the entire sensor.
Is the BL-ST-085 the same as the original Leapmotor sensor?
It is an aftermarket equivalent manufactured by Baolong Technology, which is the same OEM supplier for many Leapmotor TPMS sensors. The fit, function, and performance match the original. However, it is not a “genuine Leapmotor” branded part — it uses the BH-Sens aftermarket brand.
