I just had the engine light go on with about 1900 miles on the car and i have a device called Automatic which monitors you cars computer and it threw a code P023812 which is Boost pressure sensor. What was happening is that it was it was shorting out. The did some wiring chasing and found nothing. So they took one off a car in lot and it corrected the problem and then ordered the new sensor for me it took about three days to resolve the issue and I'm not sure if it was isolated issue or going to be a problem for others but i thought i would share my exp. But I'm back up and running so all is good in my world. They also updated the software during trouble shooting but that didn't resolve with out a new sensor.
