So after a couple of weeks of scouring the internet for info for the 2.0 TSI and a trip to the VW dealership I decided to start a thread to get to the bottom of this problem.
I recently installed my downpipe and upgraded to the APR Stage 2 tune. Five days after the upgrade I went to an Autocross event, and experienced MASSIVE amounts of white smoke pouring out of my exhaust at launch and during hard cornering. My first thought was a head gasket or oil leaking into the turbo. What I found odd was that during the week, and 500 miles, that I drove the car after the upgrade I had no smoke issues at all. It only happened when the car was being pushed hard. I drove for 3 more runs and the smoke gradually decreased in volume, but didn't go away completely. Please note that the oil was not overfilled (thought of that too). The next day I pulled the line going from the PCV to the manifold, and the line going from the PCV to the intake tubing. The manifold line had about a thimble of oil in it, and the intake line had more. I immediately took the car to the VW dealership and they told me they checked the system. They found nothing wrong, including the PCV working properly, and said that this type of blow-by is normal in the TSI when driven hard.
I've been to 2 more driving events since the visit to the dealer, and continue to have smoke issues under hard cornering and launch. I also clean the intake tubing and PCV to Manifold line before every event. There are consistent amounts of oil collected in both after each event, and 8-10 minutes of hard AutoX runs yields a 1/4 quart of oil lost.
I'm unhappy with this result, and it concerns me during track time when I reach even higher G's. Another thing to note is that I drove the car just as hard at Stage 1, but with no smoke. I'm thinking the double cats, plus the baffles in the muffler were doing a lot to filter it out.
Has anyone else experienced this, have ideas, insights, thoughts on how to completely solve this problem? Below is a list of my mods, so you can see what I'm working with.
P-Flo CAI, RAI catted downpipe, GHL catback, APR Stage 2 tune, running Dunlop Star Specs on the street, and R-compound tires at the track/autoX. Suspension mods abound.
Thanks ahead of time for any input.
