2012 C350 engine problems
I currently own a 2012 C350 it only has around 8,000 miles, and throughout the 8,000 miles the check engine light has been coming on and off. The car also idles rough. Brought it to the dealership to have it checked out several times, but they could not find a problem with it. After the fourth or fifth time the light has come on they decided that they were going to open up the engine to check it out; however, the computers still indicates there are not problems. So they contacted Mercedes in New Jersey to try and figure out what's wrong with the car. They decided that they were going to take the engine apart one by one to see what the problem is and replace the parts needed and rebuild the engine again.
My concern is are there going to be anymore problems later on and should I have just ask them to replace the engine or maybe file for lemon law? I would just like to hear what you guys think and what are your suggestions on what should I do.

Just on a side note, my car has been in the dealership for about half a month or so.
Thanks.
I thought lemon law applies for two years. So right now my only choice is to rely on the dealership to fix it. If the problem still occur I will see if they can replace the engine since it is still under warranty. Has anyone got their engine replaced before?
