A 2025 BYD Atto 3 rolls into the bay, TPMS light steady on. You scan the faulty sensor — the label is partially rubbed off, but you catch “EUEA3609…” and a barcode. The parts catalog lists both EUEA3609200B and 110964 for this model year. Which one fits? If you guess wrong, you’re pulling the tire again.
This is the reality of servicing newer BYD vehicles. Their OE numbering doesn’t follow German or Japanese conventions, so many technicians default to “just match the frequency” and end up with a sensor that programs but never reports correctly. The trick lies in understanding BYD’s three-layer part identification system.
BYD uses a prefix system: EUEA designates the vehicle platform and subsystem. The core number 3609200 is the base part identifier — this covers hardware generation, valve design, and mounting type. The suffix letter (B in this case) indicates a revision. The catch is that the service part number 110964 is a separate BYD catalog number that often supersedes the EUEA designation on later production vehicles. Both lead to the same physical sensor, but cross-referencing by only one can miss compatibility.
Here’s where the aftermarket solution comes in. The BL-ST-096 from BH-Sens is a direct replacement that consolidates both OE numbers: EUEA3609200B and 110964. It operates at 433MHz — standard for BYD’s current TPMS architecture — and uses the same snap-in valve stem design. No adapter rings, no programming modules needed if your tool supports BYD protocols.
Pro Tip: Don’t rely on visual matching alone. BYD changed the internal antenna trace on sensors between the “A” and “B” revision. An A-revision sensor will program to a B-revision car, but frequently loses signal at highway speeds above 110 km/h. Always confirm the full OE number including the suffix letter.
For shop owners stocking BYD replacements, the BL-ST-096 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD (2025+) | OE# EUEA3609200B, 110964, BLST096 cuts down the guesswork. It removes the need to carry two separate SKUs for what is functionally the same sensor across multiple 2025+ BYD sedans and SUVs. Given that BYD is pushing more models into European and Australian markets, having a single sensor that covers both the EUEA and 110964 catalog numbers means fewer returns and faster turnarounds.
If your scan tool confirms a sensor failure and the vehicle is a 2025+ BYD, start with the BL-ST-096. It’s one part that answers two different OE numbers — and that’s exactly the kind of inventory simplification a busy shop needs.
