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.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Mercedes and other vehicles will accept these Marsflex TPMS sensors?\u003c\/h3\u003e\n\u003cp\u003eThese 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.

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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-programmed to 433MHz and common OE identifiers for faster installation.\u003c\/li\u003e\n  \u003cli\u003eRelearn required via professional diagnostic scanner or TPMS activation tool.\u003c\/li\u003e\n  \u003cli\u003eIf unsure, use the seller’s vehicle fitment checker or consult a technician.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow reliable are these sensors and what maintenance should I expect?\u003c\/h3\u003e\n\u003cp\u003eMarsflex 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBattery life advertised up to 8 years; replacement requires new sensor assembly.\u003c\/li\u003e\n  \u003cli\u003eDesigned with OE-equivalent materials and testing during manufacture.\u003c\/li\u003e\n  \u003cli\u003eInspect valve stem and sensor seal when rotating tires or changing tires.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho 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.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these Marsflex sensors come ready to use without programming?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They arrive pre-programmed to 433MHz but require a TPMS relearn with a diagnostic tool for the vehicle to recognize them.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will the sensor batteries last a long time?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Marsflex states the batteries are made to last up to eight years under normal use.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Marsflex","offers":[{"title":"Default Title","offer_id":55171492184407,"sku":"B09XDLTWVP","price":62.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/marsflex-front-packaging-4pcs_26e72636-0fb5-45c1-9de4-d7a624e0b303.jpg?v=1790446784","url":"https:\/\/britishgarage.co.uk\/products\/marsflex-tpms-sensors-for-mercedes-benz-amg-sprinter-433mhz-4pcs-pre-programmed-8-year-battery","provider":"British Garage","version":"1.0","type":"link"}
