I hate to start another one of these as it seems to be asked a million times but in all my research everything seems to be the older models and manuals. I have a DSG 2012 Jetta TDI. Wife said it has to be an auto and she controls the sex in the family so ya we got an auto so please do not say swap to manual cause that is not happening. My tire pressure is at ~90% of max psi on tire side wall. I shift into neutral when going down steep hills and coast into stops and time lights to save gas. I am also light footed to save gas.
So that leaves me with my question. Has anyone started modding the newer cars to gain better gas milage and I so what have you done and what gains have you seen? What of the old TDI tricks work on the new TDIs?
