This. It should be everyone’s first mod purchase.OBD11 is by far the most popular for this platform. It scans fault codes among many other features.

Need a Hex v2/Hex-net cable for MK7+ vehicles. The older RossTech cables may work on earlier MK7s, but YMMV. Had to upgraded my Can+USB cable for some features on my 2017.I would also recommend VCDS, and try to find a 2nd hand Micro CAN interface to save money.
Also, for those referencing cheap OBD scanners, I'd highly recommend considering the OBDLink MX+. It's compatible with a ton of 3rd party apps that can access CAN modules that the inexpensive OBD scanners cannot.
Worth checking out for any other vehicles in your garage.
