Marsflex TPMS Sensors — 433MHz 4-Pack Pre-Programmed OE-Fit for Mercedes/Sprinter, Long-Life Battery

This Marsflex 4-pack offers direct-fit TPMS sensors designed to match many Mercedes-Benz models and select other makes, replacing original equipment part numbers and delivering the longevity and performance expected of OE-equivalent sensors. Each sensor ships pre-programmed at 433MHz to simplify setup, and the internal battery is engineered to last up to eight years under normal driving conditions. Note that installation typically requires a professional relearn or activation using a diagnostic scanner to fully pair the sensors to the vehicle’s onboard system.

Which Mercedes and other vehicles will these sensors fit?

These sensors are built to be compatible with a wide range of Mercedes-Benz model years and variants, including AMG lines, sedans, SUVs, vans and Sprinter applications. They also fit specific vehicles from Aston Martin, Ram, Maserati, Smart, Freightliner, Infiniti and others listed by model and year. Always verify fitment with an "Amazon Confirmed Fit" lookup or by comparing OE numbers before ordering.

• Includes coverage for many C-, E-, S-, G-, GLS-, GLC-, GLE-, and Sprinter models spanning multiple years.
• Matches OE replacement numbers such as A0009054100, A0009057200, A0009050030, and more.
• Also compatible with select Aston Martin DB11/DBS, Ram ProMaster models, Maserati Ghibli/Quattroporte, Smart Fortwo, and others.

How do I install and pair these pre-programmed sensors?

Marsflex sensors arrive pre-programmed to the correct frequency and baseline data, but they are not automatically paired to your vehicle. After mounting the sensor on the wheel, a TPMS relearn or activation process must be performed with a professional diagnostic tool or dedicated TPMS activation device. This step ensures the car recognizes the sensor IDs and displays accurate pressure readings.

• Install sensors onto each wheel valve stem and torque to manufacturer recommendations.
• Perform a TPMS relearn with a dealer-level scanner or compatible activation tool.
• If uncertain, schedule installation with a tire shop or dealership for proper programming.

What are the build and reliability features to expect?

These Marsflex sensors are new units built to OE-like manufacturing standards for durability and accuracy. The sensors use a long-life battery rated up to eight years in typical use, and manufacturing tests are performed to maintain consistent quality. A one-year after-sales service plan is included to address any early issues or defects.

• Completely new sensors, not refurbished or remanufactured.
• Battery life engineered for up to 8 years under normal driving conditions.
• One-year after-sales support from Marsflex for customer assistance.

Will these sensors match my vehicle’s OE part numbers and performance?

Marsflex TPMS sensors are designed to replace specific OE part numbers and emulate original sensor functions for pressure and temperature reporting. Confirm compatibility by referencing the OE numbers listed and cross-checking your vehicle’s requirements. Performance aims to mirror OE behavior when properly installed and relearned to the vehicle’s system.

• Replaces many OE numbers including A0009054100 and A0025409017.
• Operates at the standard 433MHz frequency used by compatible Mercedes models.
• Requires a relearn to ensure accurate sensor ID mapping to the vehicle ECU.

Who is this for: This Marsflex 4-pack is suited for owners and technicians who need OE-compatible TPMS replacements for Mercedes-Benz, AMG, Sprinter and select other vehicles. It’s ideal for professional installers, independent shops, and informed DIYers who have access to a TPMS relearn tool or dealer diagnostic equipment and want a cost-effective, long-life sensor solution that mirrors factory specifications.
