You’ve got a 2021 Porsche Cayenne in the bay. TPMS light is on, sensor IDs are dead. The customer wants OE–or at least a direct fit without chasing modules. You pull the old sensor: stamped with 3WA907255. But your catalog also lists 32134419 and 95C907255 for the same application. Which one do you order?
That confusion costs shops time and money. Here’s how to read these numbers—and why a single BL-ST-088 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Audi, Lamborghini, Polestar, Porsche, VW & 1 More | OE# 32134419, 3WA907255, 95C907255 covers all three.
The OE Numbering Maze
Automakers don’t use one global part number system. VW Group (which owns Audi, Porsche, Lamborghini, and now shares platforms with Polestar) assigns at least three formats for the same TPMS sensor:
- 9-digit VW-style (e.g.,
3WA907255) – the current VDA standard. First three digits = model platform (3WA = newer Porsche/VW MLB evo), next three = component group (907 = tire pressure monitoring), last three = variant. - 7-digit generic (e.g.,
32134419) – a GM-era carryover used by some VW/Audi divisions. Often the superseded number. - 5+5 format (e.g.,
95C907255) – a cross-reference from the aftermarket or internal supplier codes. 95C often maps to a specific frequency or protocol (433MHz, Continental-based).
The BL-ST-088 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Audi, Lamborghini, Polestar, Porsche, VW & 1 More | OE# 32134419, 3WA907255, 95C907255 (BL-ST-088) consolidates all three OE references into one sensor. That means you don’t need to stock separate parts for an Audi Q7, Porsche Cayenne, Lamborghini Urus, or VW Touareg—they all use the same 433MHz Continental-type sensor.
How Cross-Brand Equivalents Work
The real trick is understanding that the OE numbers point to the same underlying hardware: a metal-valve 433MHz sensor made by Huf or Continental, with a specific communication protocol. CourAge’s BL-ST-088 is programmed to match that protocol across multiple brands.
Technician’s Pro Tip
When a customer brings in a used Audi A8 with a sensor reading
95C907255 R, always verify the original equipment manufacturer stamped on the housing. If it’s a Continental (black plastic, silver ring), the BL-ST-088 is a drop-in. If it’s an older Schrader, you need a different frequency. This sensor works exclusively with 433MHz systems—check your scan tool first.
Common Mistakes in OE Cross-Reference
1. Trusting only one number. Shops that rely solely on the 32134419 may miss the supersession to 3WA907255. Always cross-check at least two sources.
2. Ignoring frequency. 433MHz vs. 315MHz. The BL-ST-088 is 433MHz. Fits VW Group cars built after ~2010. Don’t try it on a North American 315MHz Ford.
3. Assuming all “Audi” sensors are identical. The A4 (different platform) uses a different sensor than the Q7. Always match the OE number, not the brand.
The Bottom Line for Your Shop
For a sensor that fits Audi, Lamborghini, Polestar, Porsche, VW, and one more (that’s the Bentley Bentayga, by the way), the BL-ST-088 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Audi, Lamborghini, Polestar, Porsche, VW & 1 More | OE# 32134419, 3WA907255, 95C907255 eliminates guesswork. One SKU covers four OE numbers. Stock it, learn the numbering patterns, and you’ll cut diagnostic time on every VW Group TPMS job.
Keep a printed cheat sheet of the three OE formats near your scanner. Your bay will thank you.
