Marsflex 433MHz TPMS sensor kit is a set of four pre-programmed tire pressure monitoring sensors engineered to replace original equipment sensors on many Mercedes‑Benz models and similar vehicles.
These Marsflex sensors are built as direct-fit replacements for OE units used across a long list of Mercedes‑Benz, Sprinter, and select other marques. Each sensor arrives pre-programmed to the correct frequency and coded values to match common OE specifications, but installation requires a relearn procedure with a diagnostic or activation tool so the vehicle recognizes the new sensors. The kit promises OE-style construction, an 8-year battery life under normal use, and a one-year after-sales service window.
These sensors are compatible with a broad range of Mercedes‑Benz models (C, E, S, G, GLC, GLE, GL, SL, CLS, CLA, ML/GL/GLS families and more), certain Sprinter and Metris van years, plus selected Aston Martin, Ram ProMaster, Maserati and Smart applications. Always verify fitment using the seller’s vehicle compatibility tool or cross‑check the OE part numbers before ordering.
"Pre-programmed" means Marsflex programs each sensor with the correct frequency and identification codes before shipping, reducing setup steps. However, pre-programming does not automatically pair sensors to your vehicle; you must perform a relearn or activation so the car's TPMS module registers each new sensor.
Marsflex units are manufactured to OE-like standards and include a battery rated up to eight years under normal driving conditions. Routine tire service should check sensor valve condition, torque, and seal integrity just as you would with original sensors to maintain accurate pressure monitoring.
Who is this for? If you own a compatible Mercedes‑Benz, Sprinter, Metris, ProMaster, Maserati or select Aston Martin/Smart/Ram models and need a cost-effective OE-style TPMS replacement, this Marsflex four-pack is intended for professional installers, independent shops, and experienced DIYers who can perform or arrange a TPMS relearn using a diagnostic tool. Choose this kit when you want pre-programmed sensors that match OE frequencies and part references, but plan for a brief activation step after installation to ensure the vehicle recognizes each sensor. For any fitment uncertainty, use the vendor's compatibility checker or consult an authorized technician before purchase.
Q: Do these Marsflex sensors come ready to use without programming?
A: They arrive pre-programmed to 433MHz but require a TPMS relearn with a diagnostic tool for the vehicle to recognize them.
Q: Will the sensor batteries last a long time?
A: Marsflex states the batteries are made to last up to eight years under normal use.
