SOURCE: Check engine light/vacuum leak
First thing to remember autozone people ar not experts in the automative diagnostic world, if they were they would be earning 50 - 75,ooo per year as a technician, not 25,000 as a desk jockey. You need to go to a mechanic that has a computer to hookup to your car and tell you what the check engine light is on for. then you can fix the exact problem instead of poking around in the dark at the problem until you get lucky and have it fixed for a week or two,

the transmission on your MB is sealed with no way to check the trans fluid level,(no dipstick provided for) that is why the report says "sealed". MB did this to stop customers from overfilling there transmissions, which can cause severe damage if not done properly at the correct fluid temp, this requires special test scan tools.

Well actually this is the most embarasing code to get... It actually means your emission purge line is inoperative. Yes your scanner told you a generic definition, which is the nature of OBD 2 but, the truth is that 10 out of 10 times this code will not be fixed by replacing the gas cap. This particular code relates to any one of 3 components, and two sensors in your evap system. Test the sensors, and if they are good, then have your evap canister weighed. If it is the correct weight, then don't replace it, check the valve on the purge line, if that is fine then you have to replace the filler neck. Not because the filler neck is bad, but because there is a filter made into it which is connected to the purge line which is plugged with charcole and fuel, and this is where it gets embarasing... Its plugged because you over filled your tank too many times. Letting the pump go until it shuts its self off is very easy, but also very costly. As you have just found out.

My car (06 GS430) began giving me more frequent "Check VSC" warnings. (Code P0455 in my case. Really glad I bought that OBDII tool--resetting the codes is a snap!)
I knew that a loose gas cap could cause this, so normally I just give it a twist and it tightens. Now I found that no matter how many "clicks" I tightened the gas cap, it would not cinch down snug. The lightest turn the opposite way would open it.
I was all set to head over to CarQuest for a replacement filler cap. But I thought I'd inspect mine first just to see why it stopped holding. Upon inspection, I saw that what holds the cap in place is compression of the rubber O-ring at the back of the cap, which compresses against the filler neck. That apparently was no longer happening.
I carefully removed the O-ring from the cap--using screwdrivers to lift it over the edge of the groove it sits in. Like removing a bike tire from the rim--work your way around. Then I cut a strip of electrical tape about 10" long, and 1/4" wide. I wound this into the curved groove where the O-ring normally sits, just to build up a little thickness. Put the O-ring back in place. Done.
Now the cap tightens like it's supposed to, and thus far, it has stopped the VSC error codes. Don't know if it will fix your issue or not, Good luck.

the very 1st thing u do is have the trouble code checked that turned on the light, there are well over 200 possible reasons for a check engine light, a fuel filter is not one of them.
