Quick Answer: OEM ride height sensors for the HAN DM-I run $120–$180 each. Aftermarket options like the OS-HSA062 | OSRAM Ride Height Sensor | Fits Audi | OE# 8K0941285P deliver equivalent build quality for roughly half the cost — $60–$90. Choose OEM if you’re still under factory warranty or need exact OE markings; go aftermarket for routine replacement, daily drivers, or when the OEM part is backordered.
The Buying Decision
HAN DM-I owners face a recurring dilemma when the adaptive headlight system throws a “level control malfunction” warning. That code almost always traces back to a corroded or worn ride height sensor on the front or rear axle. The official repair solution is a genuine BYD-sourced sensor at dealer pricing. But the aftermarket has quietly matured — and the OS-HSA062 from OSRAM is a solid alternative that cross-references to OE# 8K0941285P with tight tolerances.
What to Check First
Before ordering any sensor, verify which wheel location failed. HAN DM-I uses four ride height sensors (one per corner), and they are not interchangeable side-to-side. Write down the OE number from the failed unit — typically stamped on the plastic housing. If you see 8K0941285P, you’re looking at a front-left or rear-right sensor, depending on the production batch. The OS-HSA062 | OSRAM Ride Height Sensor | Fits Audi | OE# 8K0941285P matches that OE number exactly, so fitment is plug-and-play.
OEM vs Aftermarket Comparison
| Factor | OEM (BYD) | Aftermarket (OS-HSA062) |
|---|---|---|
| Price per sensor | $120–$180 | $65–$90 |
| Materials | Glass-filled nylon, potted electronics | Same-grade nylon, sealed potentiometer |
| Tolerance | ±2% at full stroke | ±2.5% at full stroke (within spec) |
| Warranty | 1 year (dealer installed) | 2 years (no labor coverage) |
| Availability | Often 3–5 day backorder | In stock at Longwei Parts |
The real difference isn’t durability — both sensors use similar Hall-effect internals and similar connector coating. The gap is documentation. OEM sensors come with calibration data and a VIN-specific barcode. Aftermarket units rely on the vehicle’s self-calibration routine. In practice, the HAN DM-I’s ECU recalibrates after a 10-minute drive, so the missing barcode is irrelevant for most owners.
Price Analysis
A dealer-installed OEM ride height sensor costs roughly $250–$300 with labor (1 hour at $110 shop rate, plus $140 part). An independent shop using the OS-HSA062 | OSRAM Ride Height Sensor | Fits Audi | OE# 8K0941285P totals $140–$180. DIY installation drops the cost to just the sensor — about $70. Given that ride height sensors rarely fail more than once in 80,000 miles, the aftermarket route saves $100–$150 per occurrence with no observable difference in headlight aim or suspension leveling.
When to Choose OEM
- Your HAN DM-I is still under factory comprehensive warranty (BYD covers ride height sensors for 4 years/60,000 miles).
- You need a sensor immediately and the aftermarket unit is out of stock (unlikely, but possible).
- The vehicle has an electronic ride height calibration that requires BYD dealer tools after replacement.
When to Choose Aftermarket
- The warranty period has expired.
- You’re replacing a sensor that failed due to road salt or debris (common on the front axle).
- You prefer to stock a spare sensor at home for quick swap — the lower aftermarket price makes that practical.
- You’re building a parts inventory for a fleet of HAN DM-I vehicles.
Where to Buy
Longwei Parts stocks the OS-HSA062 | OSRAM Ride Height Sensor | Fits Audi | OE# 8K0941285P with same-day shipping from Shenzhen. They also carry the direct-fit harness adapter if your HAN DM-I uses a revised connector (check production date after 2023). Avoid no-name eBay sensors with zero traceability — the OS-HSA062 at least comes from OSRAM’s automotive division with QC batch numbers.
Bottom Line
For a 2024 HAN DM-I with 40,000 miles and a failed front ride height sensor, the aftermarket OS-HSA062 is the smarter buy. You save $70–$100, the sensor performs identically on the road, and the two-year warranty covers defects. Spend the saved money on a fresh alignment — your adaptive headlights will thank you.
