The BYD DOLPHIN platform has become a common sight in independent repair shops across Europe and Southeast Asia, and with that popularity comes a familiar headache: identifying the correct TPMS sensor when the original part number has worn off or the customer bought the car second-hand. The OE number EUEA3609200B looks straightforward, but the reality is that BYD’s numbering system—combined with Baolong’s cross-reference logic—has created confusion among technicians who are used to dealing with Continental or VDO sensors.
Decoding BYD’s TPMS Numbering System
Here’s the breakdown. BYD’s OE numbering follows a platform-based structure. The prefix “EUEA” denotes the electrical system category, “3609” refers to the TPMS module family, and the suffix “200B” indicates the specific hardware revision. Unlike European manufacturers who embed frequency or valve type into the part number, BYD’s system requires a cross-reference table to determine whether you’re looking at a 433MHz or 315MHz unit. For the DOLPHIN, the answer is almost always 433MHz—but not always, which is where the BL-ST-096 comes into play.
The BL-ST-096 is a pre-programmed clamp-in sensor manufactured by Baolong Technology under the BH-Sens brand. It’s pre-set to 433MHz, which covers the vast majority of DOLPHIN applications from 2025 onward. The sensor replaces OE part EUEA3609200B and also supersedes the earlier 110964 designation used in some export markets. The beauty of this unit is that it’s plug-and-play for 34 distinct BYD vehicle applications—no cloning tool required, no programming wizardry. You install it, trigger a relearn with your existing diagnostic tool, and it syncs with the vehicle’s BCM.
From a shop owner’s perspective, the real time-saver here is the pre-programmed nature of the sensor. Many aftermarket TPMS sensors arrive blank and require a programming station to write the sensor ID. That’s an extra step, an extra tool, and an extra point of failure. The BL-ST-096 skips that entirely. It’s ready to transmit the moment it’s installed. For a shop that sees multiple DOLPHIN variants in a week, that consistency is worth the slightly higher per-unit cost compared to generic blanks.
Model Year Compatibility: Don’t Assume Interchangeability
One common mistake we see in the field is technicians assuming that all BYD DOLPHIN sensors are interchangeable across model years. They’re not. The 2025+ models use the updated EUEA3609200B protocol, which is not backward-compatible with earlier 2023-2024 units that used a different data frame. If you install the wrong generation sensor, the car will report a fault within a few hundred meters of driving. The BH-Sens BL-ST-096 is specifically validated for the 2025+ generation, so double-check the vehicle’s production date before ordering.
Pro Tip: When you look up a BYD TPMS sensor by OE number, always verify the frequency AND the protocol generation. Two sensors can share the same physical shape and frequency but transmit different data structures. The BL-ST-096 is pre-programmed for the correct 2025+ protocol, saving you the diagnostic headache.
Independent Shop Economics: Dealer vs. Aftermarket
For the independent technician, the cost equation is favorable. Genuine BYD sensors from the dealer typically run 2-3x the price of the BH-Sens equivalent, and they often require a longer lead time. The BL-ST-096 offers the same functional performance—accuracy within ±1 psi, temperature compensation, and a battery life rated for 5-7 years of typical driving. The only scenario where we’d recommend skipping this sensor is if you’re working on a DOLPHIN with a 315MHz system, which appears in a small number of Japanese-market exports. In that case, you’d need a different part number.
At the end of the day, the BL-ST-096 is the sensor we stock for our own shop because it eliminates the guesswork. The OE cross-reference is clean, the frequency is right, and the pre-programmed protocol matches what BYD expects. If you’re setting up a TPMS replacement program for DOLPHIN owners, this is the unit to standardize on. Check the production date, confirm the frequency, and you’re good to go.
