2010 VW Jetta Check Engine Light

[95CrownVictoriaP74]

My MIL light came on last night at 43,976 miles. Car is running great. Of course, it is Sunday, all the VW dealers are closed....and did I mention I am 1,400 miles from home?

AutoZone scanned the P2015 code. If it is the sensor or the manifold itself, is that covered under the powertrain warranty? If not, how much is this going to cost? I just put a new set of Z rated Continental tires on the car four days ago.

This is the first problem with the car since it was purchased brand new in 11/2009. It's a 2010 VW Jetta 2.0T Wolfie.

Do I see a trade-in for a new Explorer in our future?

Light went off this afternoon after about a dozen engine start/shut down cycles while driving around.

Google to the rescue!

Intake manifold flaps sporadically stick

Which would explain your code coming up, then going away again.

Came close to trading in the Jetta today. At 45,000 miles, the intake manifold has a hairline crack in it. The check engine light came on in Maine over the weekend and went off about 12 hours later. Fortunately, it is covered under the VW Powertrain Warranty, good until 11/2014 or 60,000 miles. Not a bad thing since I just put four new Continental tires on it. Of course, the service writer said that the valves may be dirty (highly doubtful because I run AMSOIL fuel system cleaner in it every 2500-3000 miles and it runs great, anywhere from 28-34 MPG). If he calls me tomorrow, I'll gladly spend $20 in gas to inspect the valves personally if it could avoid getting hosed for the cleaning.

How does an intake manifold crack on a car with 45,000 miles on it???

The same way all the 2.0t engines do. It is a pretty common thing. There is an updated manifold.

Got the car back this afternoon. The service writer told me that the car's valves were the cleanest he had ever seen on a 2.0T. He said whatever I am doing (adding AMSOIL every 2500-3000 miles) is working. Warranty covered the replacement and repair.

While it was there, I had them service the transmission (fluid and filter change).

Cool, Glad you got your car all fixed up and running properly!

....then the battery took a $hit a couple of days later, LOL! Replaced it without incident.
