VIN Decoder: Audi & VW Vehicle Data Lookup (Solution)

Those who want to determine the standard equipment of their desired Audi model directly from the factory when comparing options during a car purchase can register under https://secure-www.audi.de/de/brand/de/tools/myaudi.htx/ on the Audi website, specifically in the section labeled 'My Audi' and then 'Add Vehicle'.
After entering the vehicle identification number (VIN), the data can be viewed under "My Audi."

Very useful for comparing what should actually be installed or if you've neglected to keep up with your service records.

It seems that the same applies to Volkswagen as well: http://www.volkswagen.de/vwcms/master_public/virtualmaster/de3/kunden___service/myvolkswagen/ihr__auto_.htx

At least, you can also enter the vehicle identification number there. (I can't say more at this time, because after that, I currently get the message: "We are currently performing maintenance work, please try again later.")
