Anyone know what code reader can read codes for a 2020? Want to be able to check my own codes without having to go to a Mercedes specialist. Dealing with random CELs after this eurocharged tune. Guessing its just a code for the catless downpipes again since they had issue coding it out the first couple of tries.

I went to autozone and unsurprisingly they were not able to pull the code for the CEL with their free scan.

That was your first big mistake, a tune that is. Take the crap off and happy driving!!
