2024 MERCEDES-BENZ Sprinter 3500

We purchased a new 2025 Jayco Melbourne and afterwards discovered the MBZ 3500 Chassis was a 2024.(6/19/2024) A 2025 MBZ 3500 chassis has a TPMS -factory installed system; 2024 no TPMS. I started to install an aftermarket TPMS and noted the tire valve stems were rubber. I couldn’t install the end cap sensors due to safety concerns about centrifugal force causing a failure of the rubber valve stems on the wheels. My next contact was MBZ customer service. They referred me to Walter’s Mercedes-Benz Van Center, 7979 Auto Drive, Riverside, Ca. 82504. I contacted Service Advisor Brennan Ruiz at 951-552-2145. After a couple of phone calls back and forth and me researching the parts through MBZ, I made an appointment on 6/11/2025 to have my 2025 Jayco retrofitted with the factory TPMS. The cost for me was approximately $3;000.00 including parts and labor. On 6/112025, Brennan took care of a warranty issue not related to this and was very helpful with the TPMS retrofit process. He did inform me that his tech would not be able to install the parts due to MBZ on the east coast refusing to release the computer code unless there was prior documentation or campaign bulletins for reference. The TPMS is standard on the 3500 MBZ Sprinter chassis, but MBZ will not release the code to their own dealership when I am willing to pay $3,000.00 for the entire retrofit process. It does not make sense to me since MBZ has the Motto on their web site: “How Mercedes-Benz Safety Features Prevent Accidents Before They Happen.” That’s what I am attempting to have completed! Resolution: First, I want this documented in case of tire failure/accident. Secondly, hopefully this will help me getting the Factory TPMS retrofit completed! I am not asking MBZ to pay anything other than releasing the computer code for the retrofit. This is for the safety of my family and all the other motorists that I encounter while driving on the highways in the US. Thank you for your help,
