Hello guys, I would like to buy a diagnosis software. I will buy a small cheap netbook. Well, I don’t know what kind of cable and software I need. I want to do the following: -read errors (this should work for every brand, this OBD2 Bluetooth part owns, but unfortunately you can’t read all the errors) -code(it would suffice me if this only worked on VW/Audi) What is it like with speedometer change ? If you use the GTI Ta Is it possible to change the KM STand with a DIAgnose program? (This is NOT a must, ALSO ONLY WHEN KM ANALYSIS FUNCTION I WANT NOT A THIRD PRODUCT) That’s all I expect. Now it should be as little as possible because I just want to make it a hobby. I thank you very much.
