Check Engine code diagnostic tool

I recently had a check engine light to come on in my 2015 S Class. I am right at about 81k miles and havent had any significant repair issues in the 6 years Ive owned the car. Just wanted to know if anyone can recommend an OBD scanner that will work best for me to pull the code and do some research on the cause of the check engine light.. I will eventually take it to a Benz dealer but wanted to tke some initial steps to get an idea of what I am dealing with.
So, I would appreciate any suggestions and recommendations on the OBD scanning tool that would be best to use at home for a non-mechanic such as myself. PLEASE NOTE THAT I DID REALIZE I AM POSTING IN THE W221 FORUM WHILE MY CAR IS W222. I HAVE ALREADY REPOSTED IN THAT FORUM, SO MY APOLOGIES FOR THAT. :-(
ANY AND ALL

responses will be greatly appreciated.

That's a W222 though.

That said you can go to AutoZone or try launch creader elite benz v2.0 scanner.

Sometimes a check engine light will come on but the next time you start the car up it will go away. Get an Xentry system if you are able to.

If I needed to buy an OBD scan tool i would buy the launch Creader Elite with Mercedes software.

I currently have a Foxwell NT530 with Mercedes software and so far it has done everything I needed it to do. Read/erase fault codes. Function test components. Show live data from the various sensors. With the help of the scan tool I fixed a fog light out that wasnt a simple bulb replacement, i diagnosed my ac blowing hot air and fixed it. Recalibrated one of my windows to work properly again.

But the Foxwell I have isnt touch screen. From my understanding the Launch will do everything the Foxwell can do or even more, and its touch screen. Which is why i would get it.

As far as Xentry I just havent needed to do anything that would require it.

Check engine light will come on for emission related issues. Could have faults in the car with alot of other things and the check engine light wont show, though a warning message may pop up on the dash with the issue. I've had the red battery warning message pop up a few times and for that I used a multimeter and one of my battery testers/monitors.

If you have a check engine light and think you fixed the cause it still make take a few drive cycles for it to drop on its own. Being able to erase the fault code then see if it pops back up comes in very handy.

Can get the launch for $100.
