I complained to this forum about my harsh ride when I first received my 4.8 a couple weeks ago. My tire light came on and I check my pressures and they had 50 PSI except for the low one. I had the dealer check a few things when I first purchased and this was one of the things. I normally have my own gauge but forgot it in the Touareg trade in! I guess I need to double check all of their other work! The 4.8 rides fine now! I will complain no more!
