For any vag owners in need of some info either regarding, fault codes, understanding adaptations/measured value blocks in the different channels, or even actuator/sensor infomation on how they work where they are and how there installed then this is the place to get it Hope its of some use to people, it helps me massively on a regular basis. Just dont go changing things unless your sure you know what your doing.
