tempertaure sensor

  1. FN2 external temperature gauge and low MPG!

    Hi guys, Since I bought my 2007 FN2 GT, I noticed that the external temperature gauge has displayed no reading whatsoever....I've also noticed that my average MPG is 22!! Whilst I'm aware that the car can be pretty thirsty, I'd still expect a bit more than that from it, or I am wrong? I drive...
