Understanding Discovery Sport TPMS Requirements
The DISCOVERY SPORT is equipped with a direct TPMS system that uses wheel-mounted sensors to monitor tire pressure in real time. This system operates on a 433MHz frequency. Most Discovery Sport models from 2014 through 2022 use this frequency, but you should confirm your specific vehicle’s year and region—some early models or non-European variants may differ.
The sensors are clamp-in type, meaning they mount through the valve stem hole with a retaining nut. This is the standard for Land Rover, and the BL-ST-081 is a clamp-in sensor, making it a direct fit for Discovery Sport wheels. Always check your existing sensor’s physical design before committing to a purchase.
Why Brand Matters: BH-Sens (Baolong Technology)
BH-Sens is a brand under Baolong Technology, a major Chinese OEM supplier for many European automakers. Their sensors are known for reliability and cross-compatibility. The BL-ST-081 is specifically designed to cover multiple brands—Aston Martin, BMW, Maybach, Mercedes-Benz, Mini, and Land Rover—because they share the same 433MHz protocol and physical dimensions.
For a Discovery Sport owner, this means you are getting an OEM-quality part without the dealer markup. For B2B buyers, BH-Sens offers consistent batch quality and programmable options, which we’ll cover below.
What to Check Before Ordering a Discovery Sport TPMS Sensor
Before clicking “buy” on any TPMS sensor, you must verify three critical things: compatibility, programming, and condition of your vehicle’s TPMS system.
1. Compatibility Checklist
| Check Point | What to Look For | Why It Matters |
|---|---|---|
| Frequency | 433MHz | Discovery Sport uses 433MHz; 315MHz sensors will not work. |
| Sensor Type | Clamp-in | Snap-in sensors are physically different and won’t seal. |
| OE Number | 36106872774, 42607WAA02, 5A3DC0401 (or similar) | Your existing sensor has an OE number on its housing. Match it. |
| Model Year | 2014–2022 (typical) | Later models may use a different protocol or frequency. |
| Tire Size | 18”–20” wheels | Sensor stem length must match wheel profile. |
How to find your OE number: Remove the valve stem cap, look at the sensor body (visible from the wheel’s outer side). It’s usually laser-etched. If you can’t see it, check your service records or contact a Land Rover dealer.
2. Programming: Pre-Programmed vs. Programmable
The BL-ST-081 comes pre-programmed to the listed OE numbers. This means it is ready to install and will be recognized by your Discovery Sport’s TPMS module after a brief drive (typically 10–20 minutes at speeds above 15 mph).
What to verify:
- Does your vehicle require sensor ID learning? Most Discovery Sport models learn automatically, but some older ones need a TPMS tool to register the new sensor ID.
- If you are replacing all four sensors, the car will learn them automatically. If replacing just one, you may need to trigger a learning procedure using a TPMS scan tool or the vehicle’s dashboard menu.
B2B Note: For bulk orders, ask the supplier if the sensors can be programmed to custom IDs. This is useful if you are stocking multiple vehicle applications and want to reduce inventory complexity.
3. Physical Condition and Installation
Inspect the valve stem for corrosion or damage. Even a new sensor can fail if the stem is bent or the sealing gasket is missing. The BL-ST-081 includes a new valve stem and nut, so use those—do not reuse old hardware.
Installation tips:
- Torque the retaining nut to the manufacturer’s specification (typically 4–6 Nm for clamp-in sensors). Overtightening can crack the sensor housing.
- Use a torque wrench. Do not guess—this is a common cause of sensor failure.
- After installation, check for air leaks using soapy water around the valve stem base.
B2B Bulk Buying Notes for Discovery Sport TPMS Sensors
If you are purchasing sensors for a workshop, fleet, or resale, the BL-ST-081 is a strong candidate due to its multi-vehicle coverage. But bulk buying requires more due diligence than single-unit purchases.
Quality and Certification
- Ask for batch test reports. BH-Sens sensors should come with a test certificate showing frequency accuracy, pressure range, and battery voltage for each batch.
- Check for certifications. Look for FCC, CE, or IC marks depending on your market. Counterfeit sensors often skip this.
- Verify packaging. Factory-sealed bags with anti-static protection indicate proper handling.
Pricing and MOQ (Minimum Order Quantity)
| Order Volume | Typical Price per Sensor (USD) | Notes |
|---|---|---|
| 1–10 units | $15–$25 | Retail pricing, may include individual packaging. |
| 50–100 units | $10–$15 | Bulk discount, often in bulk bags. |
| 500+ units | $8–$12 | Wholesale pricing; request sample first. |
Key consideration: The BL-ST-081 covers at least 7 vehicle brands. If you stock this one SKU, you can service Discovery Sport, BMW 3 Series, Mercedes C-Class, and more. This reduces inventory holding costs significantly.
Returns and Compatibility Guarantee
Always ask for a compatibility guarantee. Some suppliers will replace sensors that do not pair with the vehicle within 30 days. For B2B buyers, negotiate a trial batch of 5–10 units first. Test them on a known-good Discovery Sport to confirm auto-learning and signal strength.
Recommended Part for Discovery Sport
For a reliable, pre-programmed 433MHz clamp-in TPMS sensor that fits your DISCOVERY SPORT (and many other luxury vehicles), use the BL-ST-081 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aston Martin, BMW, Maybach, Mercedes-Benz, Mini & 2 More | OE# 36106872774, 42607WAA02, 5A3DC0401. It covers OE numbers 36106872774, 42607WAA02, 5A3DC0401, and more, making it a safe choice for both individual replacement and workshop stock.
FAQ
Will the BL-ST-081 sensor work on a Discovery Sport with a 315MHz system?
No. The Discovery Sport uses a 433MHz TPMS system. A 315MHz sensor will not communicate with the vehicle’s receiver. Always check your vehicle’s frequency first. If you have a non-European model (e.g., some Asian-market vehicles), verify with a TPMS tool before ordering.
How do I learn the new sensor to my Discovery Sport?
Most Discovery Sport models (2014–2022) use automatic learning. After installing the sensor, drive the vehicle above 15 mph for 10–20 minutes. The TPMS light should turn off. If it blinks or stays on, use a TPMS scan tool to register the sensor ID. If you don’t have a tool, a tire shop can do this in minutes.
Can I mix the BL-ST-081 with my existing OE sensors?
Yes, as long as the existing sensors are also 433MHz and clamp-in type. The vehicle’s TPMS module reads sensor IDs individually, so mixing brands is fine. However, for best reliability, replace all sensors at once if they are over 5 years old (battery life is typically 5–7 years).
What is the typical lifespan of BH-Sens TPMS sensors?
The battery inside the BL-ST-081 is rated for 5–7 years of normal use. Actual lifespan depends on driving habits, temperature extremes, and how often the TPMS system is triggered. If you are buying in bulk, check the manufacturing date on the packaging—older stock may have reduced battery life.
