Hi, love the forum! This is my first touareg. We just acquired a 2010 tdi. Upon having the car looked at for some check engine light the vw dealership tells us the car has been emissions deleted and tuned, straight pipe and all. I am shocked the car did not smell or smoke on the way home. The vehicle ran great on the 250 miles home returning about 30 mpg highway and felt peppy. Should I be concerned about the lacking of emissions equipment in respect to the mechanical reliability of the car?
