Except it isn't because it's wrong.
Quoted from iceman44:
When my long time mechanic says he can't do it, i would never venture into those waters myself
They have locked themselves into proprietary software and systems that nobody else can do.
So no, I seriously doubt you could do it yourself
No, he's either totally misleading you or totally ignorant.
VCDS is the easily available and pretty much cheap windows-based full controller for VW/Audi/etc cars. http://www.ross-tech.com/vag-com/
It's amazing what can be done with it, top to bottom full control and adjustability for all car systems, and many systems that you have never even heard of if/since you haven't deep dived this topic. For anyone who wants to maximize their VW/Audi car it is totally worth it and frankly cheap, especially if you like to wrench on your own cars or save money. And VCDS is cheap considering the other equivalent variants for the other manufacturers such as GM, Ford, Chrysler/Dodge, MB, etc. Consider it equivalent to a GM Tech 2 tool if you want to compare apples to apples. Hint, A GM tech 2 tool or emulator is not cheap. And a VCDS purchase holds its intrinsic value. One can always sell it easily later to someone else based on its sale model design with minimal loss (think $100 loss for example).
Yes, many newer Audi and VW cars will need some concurrent computer adjustments with significant brake work, but it can be done easily and at home with VCDS and big savings.
Frankly, it is easier to deep dive work on a german car at home at this time than a domestic vehicle. Those equivalent full controller emulators for domestics are notably more expensive, and unfortunately without the proven track record of VCDS.
Not being negative, hoping to help anyone who wants the help. Cheers .
