Hi, and welcome. My name isXXXXX most common faults that we see on the Mercedes cruise system is a faulty amplifier or a faulty throttle actuator. Occasionally we see a bad cruise switch. Some testing will need to be done to troubleshoot the problem or a known good cruise amplifier can be installed as a quick test.
