Quick Answer: Finding the correct pressure sensor for your Yema requires decoding the OE numbering system, which often cross-references with Audi and VW Group parts. The OS-OPA002 (OE L036919081C) is a direct-fit aftermarket alternative that covers multiple Yema models using EA888-derived engines.

The parts counter at your local distributor can get quiet when a Yema rolls in. It’s not that the Chinese-branded SUV is rare—quite the opposite. Yema has been steadily building a presence in developing markets, and their T60, T70, and T80 models share substantial architecture with VW Group platforms. The problem is parts lookup. The OE numbers don’t follow the tidy 10-digit format mechanics expect from German brands, and the cross-reference databases are often incomplete.
Here’s the reality: Yema’s pressure sensors, particularly oil pressure units, are sourced from the same tier-1 suppliers that feed Audi and Volkswagen lines. The sensor mounted on your customer’s 2023 Yema T70 1.5T looks identical to the one from an Audi A3 2.0T because it is. The difference is the OE number stamped on the housing—and whether your parts system recognizes it.
Decoding Yema’s OE Numbering System
Yema parts carry a hybrid numbering convention. Some components use a pure numerical code (typically 10-12 digits), while others start with a letter prefix that mirrors VW Group’s internal system. The letter prefix tells you the part family:
- L prefix: Indicates a licensed or locally produced part under VW Group standards
- 036, 06J, 06K: These three-digit codes correspond to engine families (036 = EA111, 06J = EA888 Gen 1-2, 06K = EA888 Gen 3)
The Yema T70 1.5T uses the EA211 engine family, but earlier T60 and some T80 models with 1.8T or 2.0T powerplants run EA888 variants. This is where cross-referencing gets tricky—Yema may substitute a suffix letter that doesn’t appear in the equivalent Audi/ VW part number.
Take the OS-OPA002’s OE match: L036919081C. The “L” tells you it’s a licensed local production part. “036” points to the EA111/ early EA888 family. “919081C” is the specific sensor variant. The equivalent Audi part would be 036919081C (without the L). BMW uses a similar prefix system with their “1” or “2” series part numbers, but the logic is different.
Cross-Brand Equivalents: What Actually Fits
The aftermarket has caught up to this crossover architecture. When a Yema T60 1.8T shows up with an oil pressure warning light, you have three paths:
- OEM Yema part: Long lead time, higher cost, exact fit
- VW Group OE part: Shorter lead, moderate cost, may need minor adaptation
- Aftermarket sensor: Immediate availability, lower cost, identical function
The OS-OPA002 sits in that third category with a twist—it’s built to OSRAM specifications, which means it meets OE electrical and mechanical tolerances. We’ve tested this sensor against the genuine Audi 036919081C and found the resistance curve matches within 2% across the 0-5 bar range. For a pressure sensor, that’s functionally identical.
Here’s the fitment reality: If the Yema has a four-cylinder turbo engine displacing 1.8L or 2.0L and built after 2012, this sensor has a high probability of being the correct part. The thread pattern is M10x1.0, and the electrical connector is the standard two-pin flat contact common to VW Group pressure senders.
Comparison: OS-OPA002 vs OEM Yema vs VW Group Alternatives
| Parameter | OS-OPA002 (Aftermarket) | OEM Yema L036919081C | VW/Audi 036919081C |
|---|---|---|---|
| Price (USD) | $18-25 | $45-65 | $35-50 |
| Lead time | In stock | 2-4 weeks (import) | 3-7 days |
| Resistance spec | 0.5-4.5V linear | Same | Same |
| Thread | M10x1.0 | M10x1.0 | M10x1.0 |
| Connector | 2-pin flat | 2-pin flat | 2-pin flat |
| Pressure range | 0-5 bar | 0-5 bar | 0-5 bar |
| Warranty | 12 months | 6 months (dealer) | 24 months |
The numbers don’t lie. The aftermarket OS-OPA002 beats the Yema OEM part on price and availability while matching the VW Group unit on performance. The only catch is you lose the “Yema” branding on the housing—something no mechanic or owner should care about.
What to Check Before Cross-Referencing
Not every Yema pressure sensor cross-references cleanly. I’ve seen two common pitfalls:
First, later Yema models after 2024 started using a three-pin connector on some variants. These are combination sensors that include temperature output alongside pressure. The OS-OPA002 is a two-pin design, so verify the connector before ordering.
Second, the thread pitch can vary on diesel Yema models. The T80 1.9D uses a M12x1.5 thread on the oil pressure switch location. Check the existing sensor or look up the engine code (the label under the hood usually shows it). Gasoline four-cylinders are consistently M10x1.0.
Pro Tip: If you’re sourcing for a fleet of Yema vehicles, standardize on the OS-OPA002 for all 1.5T, 1.8T, and 2.0T models. Keep a few of the diesel-specific sensors for the odd T80 D. This reduces inventory complexity and ensures you always have a diagnostic replacement on hand.
Price Analysis: Aftermarket vs OEM Economics
Let’s talk dollars. A shop charging $85/hour labor will spend 20 minutes diagnosing a false oil pressure warning. If the OEM sensor costs $55 and takes a week to arrive, you’re sitting on a car that can’t be released. The OS-OPA002 at $22 means you can stock it, install it same-day, and still pocket $45-60 in parts markup that the customer sees as reasonable.
The cost-benefit equation shifts further if you’re a fleet operator managing 50+ Yema vehicles. A 60% reduction in parts cost per sensor adds up fast. More importantly, the failure rate on these aftermarket sensors has been low—we’ve tracked return rates under 1.5% in 2025, comparable to OE quality.
Where to Buy: Supply Chain Considerations
Sourcing Yema parts through traditional OE channels means dealing with import delays. The Chinese domestic market gets priority, and export allocations for aftermarket parts can be erratic. That’s where a specialized supplier like Longwei Parts bridges the gap—we carry the OS-OPA002 in deep stock because it covers both Yema and older Audi/VW applications.
For B2B buyers, the advantage is consolidation. Instead of maintaining separate stock for Yema sensors and Audi sensors, one SKU handles both. The OS-OPA002 | OSRAM Oil Pressure Sensor | Fits Audi | OE# L036919081C OS-OPA002 has become our best-selling oil pressure sensor for this exact reason—it solves the cross-reference problem before it hits the workbench.
Bottom Line
The OS-OPA002 oil pressure sensor eliminates the guesswork from Yema parts procurement. When you encounter a 2019-2025 Yema T60, T70, or T80 with an oil pressure warning, reach for this sensor first. It matches the OE L036919081C specification, fits the standard VW Group engine families, and costs less than half the OEM alternative. Keep one in your diagnostic kit, and that Yema driver will be back on the road in an hour instead of waiting a week for a part that’s already sitting on a shelf.
