A 2025 HAN DM-i rolled into our bay last week with the tire pressure warning lit and the right-rear reading nothing but dashes. The owner had already been to two shops. One wanted to sell him a full set of four sensors. The other told him the system needed “dealer programming.” Neither was true — and neither had actually pulled codes. Ten minutes with a scanner showed a dead transmitter in the right rear, battery expired, everything else healthy. That’s a one-sensor job, and if you do it cleanly, it’s a 45-minute ticket with zero comeback risk.
Here’s how we handle these, because the HAN DM-i is showing up in growing numbers and the TPMS procedure has a few traps worth knowing before you touch a bead breaker.
Read the Car Before You Break the Bead
Don’t guess. Scan first. A proper OBD tool with BYD coverage will show you which wheel has dropped out versus which is just low. A flat spot in pressure usually means a slow leak at the valve stem or bead — sometimes fixable without opening the tire. A missing signal entirely points to a dead sensor battery or physical damage, and that’s when replacement makes sense.
Confirm the frequency while you’re at it. BYD runs 433MHz hardware on the HAN DM-i, and mixing in a 315MHz unit from a US-market application will pair with nothing and leave you chasing ghosts. Match the OE number off the existing sensor if the customer still has it — on recent builds that’s typically EUEA3609200B or its equivalents.
The Swap, Step by Step
Tools on the bench
Floor jack and stands, lug socket, a torque wrench that reads inch-pounds, valve core tool, the correct deep socket for the retaining nut (measure it — clamp-in nuts vary between kits), bead breaker or tire machine, rim protectors, soapy water, and an OBD scanner with BYD coverage. A TPMS activation tool helps with verification but isn’t strictly required on this platform.
Out with the old
Break the bead on the affected corner and rotate the tire until the valve stem sits opposite the sensor’s rest position in the drop center. Remove the retaining nut, pull the stem through, and lift the sensor body out through the drop center — don’t force it past the bead seat. Note the orientation before it comes out. Photograph it if you’re unsure.
In with the new
This is where we’ve settled on the BL-ST-096 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits BYD (2025+) | OE# EUEA3609200B, 110964, BLST096 as our go-to for these cars. It’s a BH-Sens unit — Baolong Technology, which supplies OE sensors to several Chinese automakers, so it speaks the same language as the factory module — and it ships pre-programmed, meaning no cloning session, no programming tool, just install and register.
Fit the new grommet dry-side down into the rim hole, lube the sealing surface lightly, and insert the sensor with the body sitting in the drop center, clear of any caliper sweep. Thread the retaining nut finger-tight, then torque it properly. Most clamp-in kits in this family call for roughly 4 N·m (about 35 in-lb) — enough to compress the grommet, not enough to crack the nylon housing. Snug the valve core, seat both beads, inflate to placard pressure, and hit the whole assembly with soapy water around the stem. Any bubbles mean redoing the seal now instead of explaining a slow leak to the customer next month.
Rebalance the wheel. Skipping this is lazy, and customers feel it as highway vibration they didn’t have before.
Relearn, Verify, Road Test
Because the replacement arrives pre-programmed, the remaining work is registration. On the HAN DM-i you’ve got two paths: a static relearn through the vehicle’s service/settings menu if your scanner supports it, or the dynamic method — set all four tires to placard pressure, then drive above roughly 40 km/h for 15 to 20 minutes while the system localizes itself. Confirm all four IDs appear in the correct corners and that displayed pressures match your handheld gauge within about 0.1 bar.
Wheel bolt torque on most HAN DM-i trims runs 110–120 N·m — verify against your data for the specific wheel.
Common mistakes we see on this job: over-torquing the retaining nut until the housing splits (it won’t leak immediately — it fails weeks later); reusing the old rubber grommet because “it looked fine”; installing the sensor body against the bead area where it gets hammered every rotation; and handing the car back before the relearn completes, which guarantees a callback with the same dash warning.
Fitment Notes Before You Order
Coverage matters more than price here. The BH-Sens part we stock carries OE references EUEA3609200B, 110964 and BLST096, and covers 34 BYD applications across 2025-and-newer builds — so one SKU handles most of what’s going to show up at your counter. At longweiparts.com you can grab the BL-ST-096 directly, and given that it’s a direct-fit clamp-in with the factory-matching protocol, it’s honestly the least complicated route for independent shops working on these hybrids.
Do the scan, mind the torque, finish the relearn. That’s the difference between a satisfied customer and a Tuesday morning callback.
