I ordered a Carista OB2 reader for $19.95 and downloaded their app on my Pixel 3 phone. It showed a lot of adjustment options on their website for the MK 7.5 Golf Sportwagen. Looking forward to trying it out.Did you go to their website and read... search here and Google?
Research more. Gather data versus opinions. Obd11 is easier, go pro version, is fairly dummy proof versus vcds.
