The Machinist

I’ve driven VW and Audi products for 20+ years, and have always used my Ross-Tech Vag-Com for diagnoses and manufacturer level procedures like recoding lighting control modules for fog and high beam, recoding TCU modules for sportier settings (the A8), throttle body alignments, new component learn, crap like that; in addition to the usual OBD scan stuff.

Is there something similar for the Mercedes vehicles? If something like a BT dongle and some time in the App Store does the trick, great, but I’m not opposed to spending more for a quality tool.

Edited to fix a few autocorrect faux-pas.
