Cannot change Engine type in vehicle profile page.
 

Trying to edit my car to reflect that it is a TDI and its not, stll showing up as a "Gas Sedan"

It's odd that you don't have an engine type listed, normally it should say "Gas L4 Sedan" and I'm guessing that's what's causing the problem here.

I couldn't duplicate the problem with a test car so I went ahead and updated your car. It should be correct now and we'll keep an eye out for that bug.
