Is there a way to monitor MPG on the PCM, I know I used to be able to do it on my '08. I have tried toggling through the different options, but cannot seem to find that one. If there is in fact one. and before you ask I did look through the owners manual and it appears to me that maybe they removed it from the 991's.

 

I have it in my '14 TTS. You need to scroll through the options on the screen right of the center one on the dash, then click on one of the options. Sorry I cannot be more help rightness, just going out. But I'll look at mine and post how to get there when I get back.

edit: If you go to the Trip Section of the Multifunction Display, you can set an Odometer to zero when you fill up, and the display will give you MPG for that particular mileage interval as it progresses.

 

Go to the area you check oil, before you do oil, you should have one that says consumption. That's your mpg

 

Did you... check the manual?

It's called the "Trip" menu, and it usually follows the Navigation/Map menu on your multifunction screen to the right of the tachometer. Scroll to it, and you'll see this picture. Your MPG is the "consumption" line.

You can reset the trips on the right (1,2,3). The first screen (#1) shows your MPG for that specific trip you are currently on.

 

Thanks all I did finally get it.
What?... there's a manual for this car...LOL
