Description

Modern VAG cars (VW, Audi, Škoda, SEAT) are packed with software-controlled features, but most owners only ever see a tiny part of what's actually possible. Plug in an OBD2 scanner, press a few buttons, and suddenly you're changing things you don't fully understand — or worse, you're blocked, confused, or staring at new warning lights. This course exists to stop that guesswork. It's built to teach you how VAG diagnostics and coding really work in the real world, not in theory and not in risky "just enable everything" tutorials. We start from the basics and move step by step: what your scanner is actually talking to, how to read fault codes properly (not just clear them), and how service functions, coding, and adaptations differ — and why that matters. You'll learn what changes are safe, what should be left alone, and how modern protections like SFD affect newer VAG cars. I'll also break down which tools make sense for DIY use and which ones just look good on paper but waste your money. Everything is explained from hands-on experience with real VAG vehicles, real problems, and real limitations. By the end of this course, you won't be blindly clicking through menus anymore. You'll understand what you're doing, why you're doing it, and how to use OBD2 on your VAG car with confidence — without turning a simple coding session into an expensive trip to the dealer.

Who this course is for

■ Owner of VAG car (Volkswagen, Audi, Skoda, Seat)
