Mercedes-Benz cars are computers on wheels. If a simple sensor like an ABS wheel speed sensor fails, half of the systems in the car will be disabled. If you want to figure out the problem, you can either go to the dealer and pay an hour or two of work, or use a good diagnostic scanner to find out what’s causing the problem, which is too expensive to buy and requires a subscription.
There are some diagnostic scanners that come very close to the functionality of Star Scanner. A good Mercedes-Benz scanner can read all data from all control units. Not just codes that cause the check engine light to come on on your dash. The best scanners can go beyond generic OBD2 codes, read original equipment manufacturer (OEM) specific codes and even provide more information about your Mercedes-Benz.
