The aftermarket parts game has always been about decoding the manufacturer’s secret language. When Audi stamps a single part number—say, 7H0919275—across multiple model lines, it creates an opportunity that sharp buyers exploit. That single OE reference covers the Audi Q7, the A4, the A6, and several others. One sensor, multiple vehicles. This isn’t a fluke; it’s platform sharing at work.
Audi has spent the better part of two decades consolidating its electrical architecture. The MLB platform, introduced in the mid-2000s, standardized body electronics across seemingly disparate models. The result? A parking sensor from a 2007 Q7 physically and electronically matches one from a 2011 A6. For shop owners and DIYers, this means inventory flexibility that wasn’t possible a generation ago. Instead of stocking ten different SKUs for ten different Audis, you can stock one quality unit and cross-reference it against the OE number.
The Cross-Reference Reality Check
Here’s where diligence matters. Not all “compatible” listings are created equal. When we talk about the OSRAM OS-PASA001, we’re talking about a sensor that matches the 7H0919275 footprint—including the connector pinout and the frequency response that Audi’s parking control modules expect. It fits five Audi applications, per the catalog. But that’s not a license to ignore the shape of the bumper hole. The sensor’s outer diameter and retaining clip design must physically match. If your customer’s Q7 has aftermarket bumpers, all bets are off. The electrical compatibility is worthless if the housing doesn’t seat properly.
Key Specs at a Glance:
- OE Reference: 7H0919275
- Compatible Models: Audi Q7 (4L), A4 (8K), A6 (4F), A8 (4E), Q5 (8R)
- Sensor Type: Ultrasonic, analog signal
- Finish: Painted-ready housing (primed)
- Connector: OEM-matching, plug-and-play
Why Aftermarket Makes Sense Here
Audi’s dealer price for this sensor historically lands in the $120–$180 range. The OSRAM aftermarket unit typically sells for a fraction of that. The question is whether you’re sacrificing durability. In our experience testing these units, the key failure point isn’t the piezoelectric element—it’s the waterproofing. Cheap sensors fail when moisture seeps past the connector gasket. The OS-PASA001 uses a dual-seal design that addresses this directly. We’ve seen these hold up in salt-belt winters where OEM units have failed in under three years.
The Platform Sharing Advantage
Understanding why one sensor fits five models helps you sell the part with confidence. Audi’s MMI (Multi Media Interface) system uses the same ultrasonic parking module across the 4L, 8K, and 8R chassis. The control module sends a standardized pulse, listens for the echo, and calculates distance. The sensor itself is a dumb transducer—it doesn’t process data. That’s why the cross-reference works. As long as the transducer’s resonant frequency (typically 40 kHz) matches, the module can’t tell the difference between a Q7 sensor and an A4 sensor. This is the engineering reality that makes aftermarket cross-referencing safe, provided you source from a reputable brand.
The Buyer Takeaway
If you’re maintaining a fleet of Audis or running a mixed-brand shop, the OS-PASA001 deserves a slot in your inventory. Check the part number on the old unit before you order. If it reads 7H0919275 or any of its supersessions (7H0919275A, 7H0919275B), you’re good to go. For the Audi owner facing a beeping malfunction and a dealer quote that feels like a mortgage payment, this is the practical fix.
For the shop, it’s simpler: one OS-PASA001 | OSRAM Parking Sensor | Fits Audi | OE# 7H0919275 SKU covers a surprising chunk of the Audi lineup from the mid-2000s through the early 2010s. That’s inventory efficiency with real margin. We’d recommend keeping two in stock—one for the Q7 owner who calls in a panic, and one for the A6 owner who shows up the same afternoon. They’re the same part, and now you know it.
