Plug and play, no recoding required.
Where exactly did you get your PnP one? It's rather confusing because some sites sell them but you need to do some extra wiring/VAG-COM work to make them work (like the ones sold on ECS Tuning).. Yet some other ones I've seen claim to be PnP.. and there are also ones (like the set sold on TM Tuning) where they also have install kits/wiring harnesses to make it PnP (Sorta)...
Any way to tell whether it's PnP or not? Can anyone verify if the OEM ones you'd get through VW in North America are PnP too?
