If you’ve spent any time behind the counter at a European specialty shop, you already know the drill. A 2019 Peugeot 3008 rolls in with a blinking amber tire pressure light. The customer wants it fixed yesterday. You pull out your scanner, confirm the left rear sensor is dead, and then comes the question that separates a smooth 20-minute job from a two-hour parts hunt: Which sensor do you actually need?
The answer isn’t as simple as walking to the shelf and grabbing a box labeled “Peugeot 3008.” With PSA Group platforms spanning multiple brands—Peugeot, Citroën, DS, and the Chinese-market Aeolus—the same physical TPMS sensor can carry three or four different OE numbers. And if you punch the wrong one into your catalog, you’ll either get a part that doesn’t communicate at 433MHz or one that arrives pre-programmed with the wrong ID logic entirely.
Let’s break down how OE number lookup works for this platform family, why cross-referencing matters, and how a part like the BH-Sens BL-ST-079 fits into a professional workshop workflow.
Decoding the OE Number System: It’s Not Random
The first step to mastering TPMS replacement on PARTNER and its PSA siblings is understanding what those OE numbers actually tell you. Citroën and Peugeot don’t use a single global part numbering scheme. Instead, you’ll encounter three distinct formats depending on the vehicle’s market origin and production year.
| OE Number Format | Example | What It Tells You |
|---|---|---|
| PSA Original (SAP) | 9802003680 | Used across EU-built Peugeot/Citroën/DS models, 10-digit format |
| PSA Updated/Service Part | 9811536380 | Supersession number, often replaces older SAP numbers |
| Dongfeng-PSA (China) | ZQ81238680 | Used on Aeolus and China-market Citroën models, “ZQ” prefix |
Here’s the trap: 9802003680 and 9811536380 are functionally interchangeable in most cases. The latter is simply a revised part number that supersedes the former. But ZQ81238680 looks completely different—it’s a Chinese domestic market number that follows a different cataloging logic.
If you’re running a shop that services imported Chinese-market vehicles or recent Aeolus models, you must know that these three numbers can point to the exact same sensor hardware. The BL-ST-079 is one of the few aftermarket sensors that explicitly lists all three OE references on its cross-reference chart, which is why it’s become a default pick for shops dealing with mixed PSA inventory.
The 433MHz Question: Why Frequency Matters for Cross-Referencing
Here’s where OE lookup gets tricky. PSA Group used both 433MHz and 315MHz sensors across different markets and years. The 433MHz band is standard for European and most Asian-market vehicles, while 315MHz appears on some North American exports and certain Asian domestic models.
A quick cross-reference that ignores frequency will land you with a sensor that physically fits the valve stem but never wakes up when the vehicle drives. The BL-ST-079 is locked to 433MHz, which covers the vast majority of Citroën, DS, Peugeot, and Aeolus applications—but it’s not a universal PSA sensor. You still need to verify the frequency on the original part before ordering.
Cross-Brand Equivalents: When “Fits Citroën” Means “Fits Peugeot, DS, and Aeolus Too”
The PSA Group’s platform-sharing strategy has been a nightmare for parts catalogers but a goldmine for aftermarket manufacturers. The EMP2 platform—which underpins the Peugeot 3008, Citroën C5 Aircross, DS 7 Crossback, and Aeolus AX7—shares a common TPMS protocol. That means a sensor designed for one model will almost always work in the others, provided the OE number matches.
Consider the practical workflow:
- Scan the vehicle to retrieve the sensor ID and confirmed fault.
- Remove the wheel and physically inspect the sensor for a stamped OE number.
- Cross-reference that number against the BL-ST-079’s fitment list (which covers 28 specific applications).
- Verify frequency—if the original sensor reads 433MHz, you’re good to go.
This is where the “pre-programmed” feature of the BH-Sens unit becomes a shop efficiency multiplier. Unlike blank sensors that require a programming tool to write vehicle-specific IDs, the BL-ST-079 arrives with the correct protocol pre-loaded. It’s a clone-in, not a program-in, solution. For a shop that sees multiple PSA vehicles per week, that saves roughly 15 minutes per job.
Real-World Fitment Notes
The 28 applications covered by this sensor aren’t just a list of names—they span multiple generations. You’ll find coverage for:
- Peugeot: 208, 2008, 3008, 308, 5008 (from 2014 onward)
- Citroën: C3, C3 Aircross, C4, C4 Cactus, C5 Aircross
- DS: DS3, DS4, DS5, DS7 Crossback
- Aeolus: AX7 (2016-2020)
One caveat: pre-2014 PSA models often used a different TPMS generation that operated on 315MHz or used a different wake-up protocol. The BL-ST-079 won’t help you there. But for the 2014-2020 sweet spot—which covers most of the high-volume service work today—this sensor covers the vast majority of what rolls through a typical European specialty shop.
Pro Tip: When you pull an old PSA sensor, look for a date code stamped near the valve stem. If the sensor is older than 8 years, don’t bother testing it—just replace it. The internal battery is the limiting factor, and at 8 years, you’re running on borrowed time regardless of what the diagnostic tool says.
The Practical Cross-Reference Workflow for Shops
Let’s walk through a realistic scenario, because knowing which OE number to look up is only half the battle. The other half is knowing how to handle the inevitable edge cases.
Step 1: Confirm the Platform Generation
If the vehicle is a 2017 Citroën C4 Picasso, you’re on the EMP2 platform. That means the sensor protocol is the same as a 2018 Peugeot 5008. You can cross-reference with confidence.
If it’s a 2012 Peugeot 508, you’re on the older PF3 platform. Different protocol, different sensor. The BL-ST-079 won’t work, and you’ll need to source the older generation sensor instead.
Step 2: Decode the OE Number Format
- 10-digit number starting with 98: This is a standard PSA SAP number. Look up the last three digits—they often indicate the supplier (e.g., 680 or 638).
- Number starting with ZQ: Chinese market. Cross-reference against Dongfeng-PSA catalogs.
- Number with an “R” suffix: Often indicates a remanufactured or service replacement part. Verify the base number matches.
Step 3: Verify Frequency Before Ordering
This cannot be overstated. The 433MHz vs. 315MHz distinction is the #1 cause of returned TPMS sensors in PSA vehicles. If you’re unsure, check the original sensor’s label—it almost always lists the frequency. If the label is worn off, check the vehicle’s owner’s manual or use a TPMS diagnostic tool to read the sensor’s response.
Step 4: Check Valve Stem Type
The BL-ST-079 is a clamp-in design, which is standard for most PSA vehicles. However, some Chinese-market Aeolus models used a rubber snap-in valve on early production runs. If you’re working on a 2016 Aeolus AX7, verify the original valve type before ordering.
Market Outlook: Why Aftermarket Sensors Are Winning
The genuine OE sensor for a Peugeot 3008 lists anywhere from $85 to $120 depending on your dealer relationship. The BH-Sens BL-ST-079 typically retails for less than half of that, and it’s functionally identical—same frequency, same protocol, same physical dimensions.
For a shop, the economics are compelling. You can stock one SKU that covers four brands and 28 applications. That’s dramatically better than carrying four different genuine part numbers and hoping you guess right when a customer calls ahead.
The aftermarket TPMS segment has matured significantly over the past five years. The early days of cheap sensors with poor reliability are fading, replaced by manufacturers like Baolong Technology (the parent brand behind BH-Sens) who actually supply OE sensors to automakers. When you buy a BH-Sens sensor, you’re buying from a company that knows the original specifications because they manufacture for the original assembly lines.
Common Mistake: Don’t assume that because the OE number matches, the sensor is pre-programmed correctly. Some aftermarket sensors are “multi-protocol” and require a programming tool to set the correct protocol. The BL-ST-079 is specifically pre-programmed for PSA vehicles. If you accidentally order a multi-protocol sensor, you’ll need to program it before installation—a step that adds time and requires an expensive tool.
Building a Cross-Reference Database for Your Shop
If you’re serious about streamlining TPMS work, start building a simple spreadsheet that links:
- Vehicle year/make/model
- Original OE number (from the physical sensor)
- Replacement part number (aftermarket)
- Frequency
- Valve type
You’ll quickly notice patterns. For example, the 9802003680 number appears on 2016-2019 Citroën C4 and Peugeot 308 models. The 9811536380 number covers the same vehicles but appears on later production runs. Once you’ve logged 20-30 vehicles, you’ll be able to cross-reference new jobs in under two minutes.
The Bottom Line on OE Lookup for PARTNER and PSA Vehicles
Getting TPMS replacement right on PARTNER and its platform siblings isn’t about memorizing every OE number—it’s about understanding the structure behind those numbers. Once you know that 9802003680, 9811536380, and ZQ81238680 all point to the same 433MHz sensor, you’ve unlocked the entire PSA cross-reference system.
For the working technician, here’s your takeaway: verify the frequency, confirm the platform generation, and use a pre-programmed aftermarket sensor that matches the OE protocol. The BL-ST-079 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Citroen, Ds, Peugeot | OE# 9802003680, 9811536380, ZQ81238680 from BH-Sens does exactly that—it eliminates the programming step, covers four brands, and carries a price point that makes it a no-brainer for shops that want to stock one part and cover a huge swath of PSA vehicles.
If you’re setting up a TPMS inventory for the first time, start with this sensor. It’s the closest thing to a universal fit for 2014-2020 Peugeot, Citroën, DS, and Aeolus vehicles. You’ll still need to check the frequency on each job, but nine times out of ten, the BL-ST-079 | BH-Sens 433MHz TPMS Tire Pressure Sensor | Fits Aeolus, Citroen, Ds, Peugeot | OE# 9802003680, 9811536380, ZQ81238680 will be the right call. It’s the kind of part that makes a shop look smart, and in this business, that’s worth every penny.
