Hello,

Looking for a scanner for a 2021 AMG GLC 43. I can't find one that stands out and tried searching but to no avail. Please let me know if you have recommendations. Thank you.

Check VehiCAL logger.

It all depends on how deep u intend to scan, say simple elm327 like this can read generic powertrain and transmission and many sensors related codes, it wont work with abs or any brand specific equipment, for that youll need advanced scanners.

I use this one for all of my cars.
