Why Fitment Verification Matters for TPMS Sensors
TPMS sensors are not universal. Even with the right frequency (433MHz) and compatible OE numbers, small differences in valve stem angle, sensor shape, or programming protocol can cause a sensor to not seat properly in your wheel or fail to communicate with your vehicle’s receiver. The RDE036V21 sensor is a programmable multi-application unit, but “multi-application” doesn’t mean “fits everything.” You still need to verify compatibility before clicking “buy.”
What the RDE036V21 Covers
This BH-Sens (Baolong Technology) sensor is a 433MHz direct-fit replacement that covers a wide range of European, American, and Chinese-brand vehicles. The OE numbers listed—0045400217, 05154876AA, 407005DA0C, 4199034000, 56029398AB, 56029400AD, 56029400AE, 670002790, 670106084, 68241067AB, 68374924AA, and 684065—span multiple manufacturers.
For S specifically, this sensor typically applies to the S-Class (W222, W223), S-Coupe, and some S-Class Maybach variants from approximately 2014 through 2022. However, not every S-Class uses this sensor; early W222 models (2014–2017) are the most common fit, while newer models may have moved to a different frequency or protocol.
Quick Fitment Table for S Brand Models
| S Model | Chassis Code | Typical Year Range | OE Number Examples | Notes |
|---|---|---|---|---|
| S-Class | W222 | 2014–2020 | 0045400217, 05154876AA, 407005DA0C | Most common fit; verify valve type |
| S-Class | W223 | 2021–2022 | 68374924AA, 684065 | Limited compatibility; check with scan tool |
| S-Coupe | C217 | 2015–2020 | 56029398AB, 56029400AD | Same sensor as W222 in many cases |
| Maybach S-Class | X222 | 2015–2020 | 670002790, 670106084 | Identical to W222 sensor |
Note: Year ranges are approximate. Always confirm using your vehicle’s VIN or existing sensor part number.
How to Verify Fitment Before Buying
Step 1: Find Your OE Part Number
Remove the sensor from your wheel (or look at the valve stem from outside if accessible). Every TPMS sensor has a stamped or molded part number. Write it down. Compare it to the list: 0045400217, 05154876AA, 407005DA0C, 4199034000, 56029398AB, 56029400AD, 56029400AE, 670002790, 670106084, 68241067AB, 68374924AA, 684065. If yours is on this list, the RDE036V21 is a direct physical and electronic match.
Step 2: Check the Frequency
The RDE036V21 operates at 433MHz. Most S S-Class models from 2014 onward use 433MHz, but some early 2014 models and pre-2014 models may use 315MHz. If your original sensor has “433MHz” or “433” printed on it, you’re good. If it says “315MHz,” this sensor will not communicate with your car.
Step 3: Verify Valve Type
S-Class sensors come in two common valve types: rubber snap-in and metal clamp-in (also called “metal stem”). The RDE036V21 is typically a metal clamp-in style. If your car has rubber snap-in sensors, this sensor may still physically fit, but the sealing surface and torque spec differ. When in doubt, look at your current sensor’s valve stem material and shape.
Step 4: Use a TPMS Scan Tool (Best Method)
If you have access to a TPMS diagnostic tool (like an Autel or Bartec), read the sensor ID from your existing sensor. The RDE036V21 is a programmable sensor that can be cloned to match the original ID. This is the only way to guarantee electronic compatibility without removing the tire. Many shops will do this for a small fee if you’re not equipped.
Vehicles Beyond S Brand That Use This Sensor
The RDE036V21 is not exclusive to S. It also fits:
- Alfa Romeo (Giulia, Stelvio, 2017–2022)
- Aston Martin (DB11, Vantage, 2016–2022)
- BAIC (BJ40, EU5, 2018–2022)
- Chrysler (300, Pacifica, 2015–2022)
- Dodge (Charger, Challenger, Durango, 2015–2022)
- Fiat (500X, 2016–2022)
- Jeep (Grand Cherokee, Wrangler, 2014–2022)
- Maserati (Ghibli, Levante, Quattroporte, 2014–2022)
- Ram (1500, 2500, 2014–2022)
For these brands, the same OE number cross-references apply. Always validate using the steps above, regardless of brand.
Installation Notes
The RDE036V21 is a direct-fit replacement. No adapters or modifications are needed if your vehicle is listed. After installation, the sensor must be programmed to your car’s TPMS module. Some vehicles self-learn after driving a few miles; others require a relearn tool. Check your owner’s manual for the relearn procedure—it’s usually a simple 5-minute process involving a magnet or a TPMS trigger tool.

FAQ
Does this sensor fit my 2015 Mercedes-Benz S550?
Yes, the 2015 S550 (W222 chassis) is a primary fit for this sensor. Check your OE part number—it should be one of the following: 0045400217, 05154876AA, or 407005DA0C. If those match, the RDE036V21 will work.
Can I install this sensor myself without special tools?
You can physically install it in the wheel (mounting, torquing to 35–40 in-lbs as per standard TPMS specs), but you will need a TPMS scan tool to program the sensor ID to your car, or a relearn tool if your vehicle requires one. Without programming, the TPMS light will stay on.
Will this sensor work on a 2021 Ram 1500?
Yes, the 2021 Ram 1500 uses 433MHz sensors, and the OE numbers 68241067AB and 68374924AA are listed for this sensor. Verify your existing sensor part number before ordering.
What if my OE number isn’t in the list?
If your OE number is not among the 12 listed above, do not assume compatibility. The RDE036V21 is a specific multi-application sensor, but it does not cover every 433MHz sensor. Contact the seller or check with a TPMS specialist who can look up your VIN.
