I put bluefin on my gti the other day, and after a couple of days the engine management light came on, I rang superchips as I thought that the bluefin may have caused this, but speaking with there technical people they said it had nothing to do with the bluefin! Bluefin handheld gizmo is telling me its fault code is p2015,The car is now returned to standard, still has the light on, and is going into the dealers on Tuesday, has anyone else had this issue with their car? Mines a 2009 dsg with 37500 on the clock and is 7 months bought from Vw Crewe, thanks guys.
