BDFHYK 315MHz TPMS Sensor for Audi A3 A4 A5 Q5 S3 S4 S5 TT, VW Beetle CC Eos GLI Golf GTI Jetta Passat 2006-2013

Q: How do I confirm this TPMS sensor fits my vehicle?
A: Match the listed Audi or Volkswagen application, 315MHz frequency, OE/interchange number, direct TPMS type, valve stem style, and relearn procedure before ordering.

Q: What frequency does this tire pressure sensor use?
A: This sensor is for compatible vehicles that use a 315MHz direct TPMS system. It should not be used on a 433MHz application.

Q: Which OE numbers should I compare before ordering?
A: Compare 1K0907253D, 1K0907253E, and 1K0907255C with the original sensor, service record, or parts reference before ordering.

Q: Does this sensor fit Audi A3, A4, A5, Q5, S3, S4, S5, or TT models?
A: It is listed for selected Audi applications shown in the fitment table. Confirm the year, OE number, 315MHz frequency, and relearn method before ordering.

Q: Does this sensor fit Volkswagen Beetle, CC, Eos, Golf, GTI, Jetta, Passat, Rabbit, or Tiguan models?
A: It is listed for selected Volkswagen applications shown in the fitment table. Confirm the OE number and frequency before ordering.

Q: Is this listing for one sensor or a set?
A: This product includes selectable 4PCS and 1PC options. Check the selected quantity before checkout.

Q: Do I need to replace all four TPMS sensors at once?
A: You can replace one failed sensor if only one wheel sensor is faulty. Many owners replace all four when the sensors are the same age, batteries are weak, or wheels and tires are already being serviced.

Q: Does this TPMS sensor need programming?
A: Blank-sensor programming is not required for this application. Sensor activation and the vehicle relearn procedure may still be required after installation.

Q: Why is the TPMS light still on after replacing the sensor?
A: The relearn procedure may not be complete, tire pressure may still be incorrect, the vehicle may require a different frequency or OE reference, or another TPMS component may have a fault.

Q: What does a flashing TPMS light usually mean?
A: A flashing TPMS light can indicate a sensor communication issue, low sensor battery, relearn problem, or receiver/module issue. Check tire pressure first, then scan or relearn the TPMS system as needed.

Q: Can this sensor fix a missing tire pressure reading?
A: It can help when the missing reading is caused by a failed or non-communicating wheel sensor. Vehicle fitment, sensor activation, relearn completion, and receiver condition should also be checked.

Q: Can I install this sensor without removing the tire?
A: Most direct TPMS sensors are mounted inside the wheel at the valve stem, so tire dismounting and wheel balancing are usually required.

Q: Do I need a TPMS scan tool?
A: Many vehicles require a TPMS activation tool, scan tool, or OE relearn steps after installation. Check the service procedure for your vehicle before installing the sensor.

Q: Is this an original equipment sensor?
A: No. This is a BDFHYK OE-style aftermarket replacement TPMS sensor. Use the OE numbers and fitment details to confirm compatibility before ordering.

Q: What should I check before checkout?
A: Verify the 315MHz frequency, OE number, vehicle year and model, direct TPMS type, valve stem style, selected quantity, and relearn procedure.
