The BYD QIN L DM-I has become a fixture on Chinese roads since its 2024 debut, and by 2026, the first wave of factory TPMS sensors is hitting the 5-6 year replacement window. Owners are discovering that dealer pricing for the OE unit—part number EUEA3609200B—runs steep, and that’s pushing the aftermarket to respond. The good news: cross-reference data has matured enough that shops can now match the BYD sensor to a compatible 433MHz unit without guesswork.
The OE Number Maze
BYD doesn’t follow the same numbering logic as Toyota or VW. The EUEA3609200B designation breaks down as: “EUEA” identifies the vehicle platform (QIN L DM-I generation), “3609200” is the component family code for tire pressure monitoring, and the trailing “B” indicates a revision—meaning early-production sensors were superseded. That revision matters. If you install a first-generation sensor into a late-2025 QIN L DM-I, you’ll get intermittent signal dropouts at highway speeds.
Cross-referencing gets interesting when you look at supplier-level numbers. BYD sources TPMS from Baolong Technology, and their internal part number for this exact sensor is 110964. That’s the number to search for when digging through aftermarket catalogs, because Baolong supplies multiple automakers with the same 433MHz hardware under different OEM labels.
What Fits and What Doesn’t
The BL-ST-096 from BH-Sens is a pre-programmed, clamp-in sensor that matches the QIN L DM-I’s frequency and protocol. Since it’s pre-programmed, there’s no cloning tool required—install it, relearn it via the vehicle’s TPMS menu, and you’re done. The sensor covers 34 BYD applications, which makes it a practical stock item for shops servicing the broader BYD lineup, not just the QIN L.
Key Specs:
- Frequency: 433MHz
- Type: Clamp-in, pre-programmed
- OE Cross-Refs: EUEA3609200B, 110964
- Fitment: BYD QIN L DM-I (2025+), 34 total applications
- Brand: BH-Sens (Baolong Technology manufacturing)
Market Reality Check
The pricing gap is the story here. A dealer OE sensor runs $65-85 depending on region. The BH-Sens BL-ST-096 | OE# EUEA3609200B, 110964, BLST096](https://longweiparts.com/product/bl-st-096-bh-sens-433mhz-tpms-tire-pressure-sensor-fits-byd-2025-oe-euea3609200b-110964-blst096/)) typically lands at half that, and the pre-programmed nature eliminates the $20-30 programming fee that many independent shops tack on for blank sensors. For a four-tire replacement, that’s real money.
One caveat: the QIN L DM-I’s TPMS system uses a rolling code that resets after battery replacement. If a customer brings in a car with one dead sensor and you’re tempted to “just swap the battery,” don’t. The housing seal is compromised once opened, and moisture ingress will kill the sensor within months. Replace the unit.
Buyer Takeaway
The aftermarket for BYD TPMS has reached maturity. The BL-ST-096 | OE# EUEA3609200B, 110964, BLST096](https://longweiparts.com/product/bl-st-096-bh-sens-433mhz-tpms-tire-pressure-sensor-fits-byd-2025-oe-euea3609200b-110964-blst096/)) is the sensible pick for shops that see QIN L DM-I models regularly—stock it, learn the relearn procedure, and you’ll capture business that dealers are currently overcharging for. For the owner, the math is simple: same Baolong hardware, different badge, half the price. The only reason to skip aftermarket is if you’re still under warranty, and in that case, let the dealer handle it.
