thanks buddy. I read most of it more or less but what convinced me to buy this car is the fact that it has real mileage and clean history from the dealer.Welcome. If you haven't read it already, do take time to carefully read the buying a used Touareg thread - the link is in my signature below. You will probably learn a lot and save money later too!
One other thing, the Firmware of your MFD (Multi Function Display) is an early version which has been replaced as the result of a service bulletin. That version has the bad habit of failing to display certain items, such as the bar graph for Air Suspension ride level and a few others.. I have attached the service bulletin details. Have a talk to a VW dealer and get it upgraded. (Looks like your Air Suspension Bar Graph is still ok at the moment)
You can identify the later firmware as it displays the Outside Air Temp in the Top Left Corner of the Display, where the original in the box on the lower right.
