I have a 2019 C300. had my check engine light go on and off for over a year. Recently once it came on the car went into limp mode. I was driving down the highway and felt a tiny jolt. When I pressed down on the pedal the car would not respond. I didn’t want to stop, so I put it in cruise control to maintain the speed. Even in cruise control the speed kept going down. The car speed does go up but it takes forever to go up. The RPMs stay at 1.

I took it to the shop and this is what they wrote “checked for DTCs found P017200 cylinder bank 1 mixture too rich, P019185 pressure rail has malfunction, P164B07 camtronic is in limp-home mode. there is a mechanical fault. and P003C09 camtronic intake solenoid 1 fault of stuck in off position.” Their solution was this: “Removed and replaced camshaft lift solenoid actuator. Cleared all code and test drove vehicle multiple times to ensure no codes come back on. No engine light on at this time all working properly.”

Everything was fine for a week until this morning. I was driving to work when I felt the car was not accelerating when I pressed on the pedal. I looked down and the check engine light is on again.

Can anyone tell me is this has happened to them and what was the solution and cost?
