Understanding the OEM vs Aftermarket Decision for UNI-T
The UNI-T uses a standardized 433MHz TPMS sensor system. When a sensor fails, you have two paths: buy the OEM part (typically branded as Changan or UNI-T genuine) or choose an aftermarket alternative. The key difference is not performance—it’s price and programming method.
OEM Sensors: When They Make Sense
- Under warranty – Replacing with anything other than OEM can void remaining coverage.
- Dealer-only programming – Some later UNI-T models require dealer-level diagnostic tools to learn new sensors. If your local shop can’t program aftermarket units, OEM may be the only plug-and-play option.
- Insurance or fleet requirements – Some commercial policies mandate OEM parts.
The downside? OEM sensors from UNI-T or Changan typically cost 2–3x more than quality aftermarket units, with no functional advantage.
Quality Aftermarket Alternatives: The BH-Sens Solution
Aftermarket TPMS sensors have matured significantly. Brands like BH-Sens (manufactured by Baolong Technology, an OE supplier) produce sensors that match or exceed OEM specifications.
BH-Sens BL-ST-057 Specifications
| Parameter | Value |
|---|---|
| Frequency | 433MHz (matches UNI-T) |
| Type | Clamp-in, pre-programmed |
| OE Cross-References | 3601010CD01, 3601010DG01, 3601010MK02 |
| Compatible Brands | Avatr, Changan, Deepal, Mazda, Nevo |
| Programming | Pre-programmed – install and relearn |
The BL-ST-057 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 is a direct replacement for UNI-T models using the above OE numbers. It comes pre-programmed, which means you don’t need a TPMS cloning tool—just install it and perform a standard relearn procedure (detailed in your owner’s manual).
Price/Value Analysis
| Factor | OEM Sensor | BH-Sens BL-ST-057 |
|---|---|---|
| Typical Price (per sensor) | $45–$70 | $18–$25 |
| Warranty | 1–2 years | 2 years |
| Programming Required | Usually dealer | Pre-programmed |
| Build Quality | OE standard | OE-equivalent (Baolong) |
| Fitment Guarantee | 100% | Verified for OE numbers listed |
The aftermarket sensor saves you 60–70% per sensor. For a UNI-T with four sensors, that’s a savings of $100–$200.
Installation Considerations
Both OEM and the BH-Sens aftermarket sensor install the same way:
- Remove tire from rim
- Remove old sensor (usually a 10mm or 11mm nut)
- Install new sensor with new seal kit (torque to manufacturer spec—check your manual)
- Rebalance tire
- Relearn sensors via TPMS tool or driving procedure
The BH-Sens unit is pre-programmed with the correct 433MHz ID, so you skip the cloning step required by some universal aftermarket sensors.
Recommended Part
For UNI-T owners outside warranty, the BL-ST-057 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Avatr, Changan, Deepal, Mazda, Nevo & 1 More | OE# 3601010CD01, 3601010DG01, 3601010MK02 is the smart choice. It delivers OEM-level reliability at aftermarket pricing, sourced from Baolong—an original equipment manufacturer for multiple Chinese automakers.
FAQ
Can I use the BH-Sens sensor on my UNI-T if I don’t see my exact year listed?
Check your OE number printed on the original sensor. If it matches 3601010CD01, 3601010DG01, or 3601010MK02, the BL-ST-057 fits. When in doubt, remove one sensor to verify the part number.
Will a pre-programmed sensor trigger a warning light?
No. Pre-programmed sensors already contain a unique ID. After installation, you must perform a full relearn procedure (usually a 2–3 minute driving sequence or using a TPMS tool). The light will remain on until relearn is complete.
How long do aftermarket TPMS sensors typically last?
Quality aftermarket sensors like BH-Sens have a battery life of 5–7 years, comparable to OEM. The BL-ST-057 uses a sealed lithium battery rated for the same lifespan as factory units.
Is it legal to use aftermarket TPMS sensors?
Yes, in all markets. Aftermarket TPMS sensors are regulated under the same FMVSS 138 (US) or UN ECE R64 (EU) standards as OEM. They are not “counterfeit”—they are alternative manufactured parts that meet the same specifications.
