Hey, I’ve got a golf mk6 gt tdi 140. Last week the coil light came on and then car went into limp mode and got code p2563. Reset code but light came back on and car back in limp mode. Friend checked it and says was turbo actuator, changed that and was fine for a day but then coil light came back on and car in limp mode again. Reset code and hasn’t come back on yet and out of limp mode. The actuator was set up by matching to old 1 not by vcds, could this be causing the problem or is it more likely to be something else? N75 maybe? How would I test this?
