You simply cannot be more newb than I! I dare you. My wife and I are the proud owners of a new TDI Sportwagen and so far we LOVE it! Where have turbocharged diesels been all my life? It is the first "driver's car" I have ever had. Right now we are overwhelmed at all the info regarding VW TDIs and we can see the learning curve is very steep at first. So far everything has been running smoothly but I have noticed that when the car is first started up and driven it surges and hesitates, if that is an apt description. Perhaps shuddering is a better word. Like a poorly jetted motorcycle with a tight spot in the drive chain. Sport mode makes it a little better due to the higher rpms but in reading this site I have not heard anyone mention this so I thought I should ask. Thanks.
