He did not reply directly to my email.
Instead it was answered by a Customer Service Manager.
Your email to Mr. White was forwarded to me for review and response. I would like to thank you for taking the time to provide us with your feedback and for your loyalty to our Brand over the last 12 years. I apologize that you did not find your driving experience of our 2012 Tiguan a pleasurable one because of the 6-sp transmission and its programming. The programming was done in such a fashion as to optimize the fuel consumption of the vehicle. We will certainly document your displeasure and will make sure that our Product Planning Specialists are made aware of your comments. Unfortunately, there is no programming changes planned at this time for the vehicle as it would take it out of advertised fuel consumption ratings.
