We have a 2005 Passat TDI Wagon. The ECM is sporadically not sending the ground signal to the N75 valve and it is throwing an underboost and emissions workshop message. It clears itself and can be fine for two days or two weeks before it comes back.
Can anyone recommend where to send the ECM out for testing and possible repair?
Thanks
