I had a turbo failure last week in my 2013 6 speed passat. I experienced the flashing glow plug and check engine light and pulled the code saying it was the mass air flow sensor (scangauge - code P0101). Cleaned it and put it back together and it drove fine for a few days. Went out one morning and the car wouldn't start. Had it towed to the dealer and they called me to say the boost pressure sensor was bad. They replaced the sensor and got the car started, then began to do the turbo update and it apparently threw a code about the turbo. They called me to say the turbo was covered in oil and they replaced the turbo and DPF under warranty. VOA will not cover the replacement of the boost pressure sensor or towing, saying this was an unrelated issue and that the turbo didn't fail until the software update was done. This doesn't seem like a likely scenario to me. What do you guys think? Where is the boost pressure sensor in relationship to the turbo? If the turbo was throwing oil, couldn't it have caused the sensor problem?
