Gas Line Leak
I already am bringing the car in for service this week but just thought Id create a thread on this. I started noticing very feint gas smell inside the cabin coming from the air vents. I keep my fan on all the time (no ac). The smell is not continuous as sometimes the air smells clear, but as a few more days went on, the smell started getting stronger. At some points it was so bad it was causing me to gag. Opening up the hood didnt show any immediate signs of gas leaking until yesterday when I noticed it in the cabin, pulled over and opened the hood, and could smell it on the bottom, right hand side of the engine. Anyway, I have a laundry list of warranty items to look at as well, such as my navigation is all messed up and shows me in the middle of the ocean, and the squeaking brakes.

There have been a few issues with the rubber lines leaking near the transmission tunnel or at the high pressure fuel pump. There is also an updated antenna available that usually will fix your nav issue. There will be a fault code for the nav antenna that the dealer can get with the SDS. Let me know if you have any other Q's before you go in for service
