Now my biggest dilemma is:

How do i reset the Trouble Codes when I'm done ?

Carsoft 7.4 is only 85$ but i'm afraid i'll curse everyone trying to make it work and will have limited access to the rest of the modules on the car.

Star C4 is overkill in my situation @ 800$ for the Kit

Star C3 seems reasonable at about 350$, but i haven't found a seller i can trust yet.

(I used to be a bosch certified technician and have experience with good scan tools and german cars. I just switched to Mercedes after owning pretty much all the BMW models up to 2006. I have the latest BMW ICOM that costed me about 4k and used to do everything related to warning lights and electronic malfunctions)

Now i'm trying to find something for Mercedes that would give me similar performance without forgetting i'm just a DIYer
