How to resolve the Volkswagen SRFE issue?

It is necessary to visit a 4S dealership to have the key information rematched; this cannot be restored on your own. Visit the 4S dealership to reset the chip and rematch the key information; otherwise, it will affect the normal operation of the car's ignition and driving.
I've been repairing Volkswagen cars for over a decade, and an SRS warning light is no small matter. The most common cause is sensor failure, such as a loose or dirty occupancy sensor under the seat, or a malfunctioning seatbelt pretensioner. Wiring harness corrosion is also an issue, as Volkswagen models are prone to short circuits in humid conditions. Inspection steps: First, read the OBD-II error codes using a diagnostic tool—Volkswagen vehicles can use the VCDS system; determine whether it's a sensor or control unit issue. Minor issues can be addressed by tightening connections or cleaning contact points yourself. However, the airbag system operates under high voltage and is dangerous—never disassemble it carelessly, as improper handling could cause accidental deployment. Low battery voltage can also trigger false alarms, so check that it's above 12V. Safety first—it's best to visit a 4S shop or certified repair center for a full inspection, which typically costs a few hundred dollars to resolve.
Driving my Volkswagen Passat, the SRS light suddenly came on, which is quite annoying. I checked online and found many owners with similar issues: food or dust stuck on the seat sensor, which might be resolved by simply wiping it; the seatbelt buckle might be loose or broken, so try reinserting it after checking. If the problem persists, it could be an issue with the airbag control computer. A temporary solution: park and turn off the engine, disconnect the negative battery terminal for five minutes and then reconnect it, which sometimes resets the system. However, having non-functional airbags is dangerous, especially in high-speed accidents where injuries could be more severe. Volkswagen parts aren’t cheap, so a visit to the repair shop might cost around 300 yuan to replace the sensor or wiring harness. To prevent this, avoid spilling water in the car or placing heavy objects on the seats.
As an automotive electronics technician, SRS system failures typically stem from sensor malfunctions such as crash detectors or seatbelt buckle failures, or control module damage causing communication interruptions. Diagnosis should prioritize using Volkswagen-compatible scanners to read fault codes (e.g., U-series errors) and checking power supply lines and grounding integrity. Common repairs include replacing sensor components or reprogramming the ECU; if wiring harnesses are aged, rewire or shield interference sources. SRS repairs must be handled by professionals to avoid accidental airbag deployment causing injuries. Avoid installing improper electronic devices in daily use to maintain system stability.
