Hello Lewis,
Yes. Benz company rules after some time, you need go to professional 4S store to maintain SBC. If not, then your SBC will have C249F fault code. And you cannot speed up. Use this tool, you can clear the C249F fault code and activate the SBC again, then your car will work like you have gone to 4S store for maintenance. And work normally.

Hello Voytek,
This one can read and clear this CF249 fault code. If you only want to read and clear the fault code, then use this one. The support car models and year are listed on the page. If your SBC is broken, then need to go to your local repair shop to do. This one has the 16 pin port, so cannot work on the car models which is non-16 pin. If you have bought Benz mb star series, then do not need to buy this one, you can use your benz star to work on this function. Old car models use DAS, new car models use Xentry. If your car model needs to open the special function to do, then it will ask the code for you. If not ask the code, then directly use benz star to work on your car.
