A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does OTA - 5496430 cover?
The manufacturer filed it against 34 model years across 2 brands (Mercedes-Benz and Mercedes-Maybach): 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class, 2024 Mercedes-Benz CLE-Class, 2025 Mercedes-Benz E-Class, 2024 Mercedes-Benz E-Class, 2023 Mercedes-Benz E-Class and more.
