Quick Answer: The OS-HSA007 (OE# 8R0941285G) is a direct-fit aftermarket ride height sensor from OSRAM, designed for specific Audi models. Before placing a bulk order, verify the exact vehicle platform (e.g., Audi Q5 8R), suspension type (air vs. coil), and sensor position (left/right, front/rear). B2B buyers: one wrong SKU can blow your margin on the next ten orders. Use this checklist to cross-check every shipment.
—
The ride height sensor market for European cars has gotten crowded. With OE prices hovering around $150–$200 per unit for many Audi platforms, aftermarket alternatives are flooding in—some good, some sketchy. The OSRAM OS-HSA007 stands out because it’s built to OE specs without the dealer markup. But that doesn’t mean you can blindly order 200 pieces and hope they fit.
If you’re a B2B buyer—shop owner, distributor, or fleet manager—you already know that returns and mis-ships destroy your profitability faster than a bad supplier. The problem is that Audi uses at least three different ride height sensor part numbers across the Q5, A4, A5, and Q7 families, and each one has specific wire harness connectors and mounting brackets. The OS-HSA007 maps to OE 8R0941285G, which covers a narrow but high-volume slice of Audi’s lineup.
What to Check Before You Click “Order”
1. Vehicle Application and Position
The OS-HSA007 is listed for one primary application—typically the front suspension on the Audi Q5 (model years 2009–2017 with the 8R chassis) and related derivatives. But “front” isn’t enough. Left and right sensors are often different part numbers. The OE 8R0941285G usually goes on the front left side. If you’re stocking for a repair shop that sees a lot of Q5s, you’ll also need the right-side sensor (OE 8R0941286G) to complete the set. B2B mistake #1: ordering a single SKU in bulk without confirming whether your buyers need both sides.
2. Suspension Type – Air vs. Coil
Audi’s adaptive air suspension and standard coil-spring suspension use different ride height sensors—sometimes different mounting points, always different rod lengths. The OS-HSA007 is designed for the standard steel-spring suspension. If a customer accidentally orders it for an air-suspension Audi Q5, the sensor arm won’t reach the lower control arm. Yes, it happens. Add a line item in your internal catalog to flag this.
3. Connector and Pinout Verification
OE sensors from this generation use a three-pin connector, but the pin assignment can vary. The OS-HSA007 matches the OE connector pattern precisely. However, knockoff sensors from unknown brands sometimes swap the signal and ground wires. If you’re buying in bulk, request a sample first. Plug it into a known-good harness on a test vehicle. A 5-minute bench test can save you from sending out 50 sensors that throw a fault code the moment the ignition is on.
4. Quality and Origin of the Aftermarket Brand
OSRAM is not a fly-by-night name. The company has been making automotive lighting and sensors for decades. The OS-HSA007 uses the same core Hall-effect technology as the original Audi sensor. But not all aftermarket ride height sensors are equal. Compare the warranty terms: OSRAM typically offers 2 years against defects. Some no-name alternatives offer 6 months. For B2B buyers, the warranty period directly affects your liability if a sensor fails in a customer’s car.
5. Bulk Pricing and MOQ
When you buy directly from a distributor like longweiparts.com, the per-unit price drops significantly compared to OE dealer pricing. The OS-HSA007 is priced competitively for wholesale orders. Just make sure to confirm the minimum order quantity (MOQ). Some suppliers require a 10- or 20-piece minimum per SKU, which is fine if you have the demand. If you’re just testing the waters, ask about sample pricing first.
| Factor | OE Audi Sensor | OSRAM OS-HSA007 |
|---|---|---|
| Price per unit (est.) | $150–$200 | $45–$65 (wholesale) |
| Warranty | 1 year (dealer) | 2 years |
| OE cross-reference | 8R0941285G | Exact match |
| Availability | Special order, 3–5 days | Stocked, ships within 24h |
| Connector fit | Guaranteed | Matches OE, verified |
| Bulk discounts | Rare | Available at MOQ |
B2B Bulk Buying Tips That Actually Work
- Don’t rely on the OE number alone. Even within the same chassis, Audi made running changes. The 8R0941285G supersedes earlier numbers. Check the original part on the vehicle. Remove it, read the casting, and compare.
- Use a single reliable source for multiple sensors. If you’re stocking ride height sensors, you’ll probably also need other suspension sensors (steering angle, acceleration). Consolidating orders at longweiparts.com reduces freight costs per unit.
- Watch out for packaging variations. Some aftermarket sensors come in bulk bags without proper labeling. If you resell to shops, you need clear branding and part numbering to avoid confusion. The OS-HSA007 ships in branded OSRAM packaging with the OE number listed.
- Build redundancy for fast-moving SKUs. If you sell to shops that service Audi Q5s, you will sell a left front sensor every three weeks. Stock at least two months of lead time plus a safety buffer.
Common Mistakes (And How to Dodge Them)
Pro Tip: One shop I know ordered 30 ride height sensors for Audi Q5s, all the same SKU. Three weeks later, they discovered that 12 of them were for the rear axle, not the front. The supplier had mislabeled the boxes. The fix? Insist that every carton has the OE number printed on the label, not just the aftermarket SKU.
Another mistake: assuming all 8R0 cars use the same sensor. The Audi Q5 from 2017 onward switched to a different sensor design entirely. The OS-HSA007 fits up to around 2016. Always confirm the year with the customer. Use the VIN if possible.
Where to Buy
For B2B buyers, your best bet is to work directly with a specialist that sources from China and understands the Audi platform. Longweiparts.com stocks the OS-HSA007 | OSRAM Ride Height Sensor | Fits Audi | OE# 8R0941285G and can offer volume pricing that beats most distributors. They also provide technical support—so if you’re unsure about compatibility for a specific VIN, you can ask before you place a PO.
Bottom Line
The OS-HSA007 | OSRAM Ride Height Sensor | Fits Audi | OE# 8R0941285G delivers OE-level reliability at a fraction of the dealer price. But for B2B buyers, the real value isn’t just the lower cost—it’s the ability to order with confidence. Use this checklist every time you replenish. Verify the vehicle platform, check left vs. right, confirm air vs. coil, and test a sample first. Do that, and you’ll keep your customers’ Audi Q5s rolling smoothly while your margins stay healthy.
