Senova owners and independent shops face a peculiar problem when the tire pressure light starts blinking. The brand—BAIC’s passenger car division—uses TPMS sensors that carry multiple OE numbers depending on the model year and assembly plant. And here’s the kicker: the same physical sensor that fits a Senova D50 also fits a Buick Regal. That’s not a coincidence. That’s platform sharing.
The BL-ST-059 from BH-Sens (Baolong Technology) is a 433MHz clamp-in unit pre-programmed to cover 116 vehicle applications across BAIC, Buick, Cadillac, Chevrolet, and 15 more brands. But before you click “add to cart,” you need to understand how OE number lookup actually works for Senova—and why guessing by brand name alone will get you a return label.
Decoding Senova OE Numbers: The Structure
Senova TPMS sensors don’t use a unified numbering scheme. You’ll encounter three distinct formats depending on the parts catalog:
- GM-style numbers (e.g., 13516165, 13522631): These come from the Delphi/Baolong supply chain shared with GM models. The 8-digit format groups by frequency band and sensor generation.
- BAIC internal numbers (e.g., B21-3797010): These follow Chinese OEM conventions—a model code prefix followed by a part sequence. They rarely cross-reference internationally.
- Vendor-specific numbers: Some Senova service parts carry the Baolong catalog number directly, which is why the BL-ST-059 lists three GM OE numbers but fits Senova vehicles.
The practical takeaway: if you’re looking up parts for a Senova D50 or X65, search the GM OE numbers first. BAIC’s aftermarket support outside China is thin, but GM’s global parts network covers the same sensor hardware.
Cross-Brand Equivalents: What Actually Interchanges
The BL-ST-059’s fitment list isn’t marketing fluff—it reflects the shared supplier architecture between BAIC and General Motors. Here’s the breakdown:
Key Specs
- Frequency: 433MHz
- Type: Clamp-in, pre-programmed
- OE References: 13516165, 13522631, 13540603
- Compatible Brands: BAIC, BAIC EV, Buick, Cadillac, Chevrolet, plus 15 additional makes
- Applications: 116 vehicle models
This sensor generation uses the same mounting torque (7-9 Nm) and valve core design across platforms. If you’ve installed one in a Chevy Cruze, the process is identical for a Senova X55. The pre-programmed nature means no cloning tool is required—it broadcasts the standard 433MHz protocol that Senova’s BCM expects.
One caveat: early Senova EVs (2015-2017) sometimes used a 315MHz sensor in export markets. Verify the frequency before ordering. The BL-ST-059 will not work on those.
Practical Cross-Reference Workflow
When a customer brings in a Senova with a dead TPMS sensor, do this:
- Read the old sensor’s ID using a TPMS tool. The sensor ID itself doesn’t need to match, but the frequency and protocol do.
- Check the valve stem material. Aluminum stems indicate the clamp-in design; rubber stems mean a snap-in sensor—different mounting entirely.
- Cross-reference the OE number against the BL-ST-059’s list. If you see 13516165 or 13522631, you’re good.
- Program and test-drive above 25 mph for 5-10 minutes to confirm the BCM accepts the new sensor.
Pro Tip: Don’t trust “fits Senova” listings that don’t list specific OE numbers. Some aftermarket sensors from unknown Chinese brands use generic 433MHz protocols that won’t sync with Senova’s BCM. Stick with known suppliers like Baolong that invested in actual OE validation.
The Bottom Line for Senova Owners
Most Senova TPMS failures are battery-related (sensors last 5-7 years) rather than crash damage. When replacement time comes, the BL-ST-059 offers a cost-effective path that doesn’t force you to source from a BAIC dealer at triple the price. The cross-brand compatibility means your local parts store likely stocks it—or can get it within a day.
For shops: keep one or two in stock. The Senova owner base in North America is small, but the same sensor covers the far more common Buick and Chevy models, so inventory turnover won’t be an issue.
For DIY owners: verify your model year and frequency before ordering. If your Senova is 2018 or newer, the BL-ST-059 is almost certainly the correct drop-in replacement. Older export models? Check first.
