andybg40 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Bit of a weird one has happened on my VR today. After changing the MAF unit ( the car is so much better now!!) and getting a few miles down the road i noticed that the fuel gauge was reading full when it is only half? Then when i started to drive hard it dropped down to empty, then went back up to full again? When the needle goes up it kinda jumps in little stages too, not smoothly. I don't think changing the MAF has caused this, it's just coincidence, but what else could it be?CheersAndy Link to post Share on other sites
adam_christie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Definitely sounds like something's shorting out somewhere. Although I've heard of a MFA "hack" that allows your fuel guage to act as a MPG indicator..... It was on this forum too..... Link to post Share on other sites

andybg40 0 Posted October 1, 2007 Author Report Share Posted October 1, 2007 I used to do that on my g60 to monitor boost. I'm guessing a wiring fault somewhere. Does any of the wiring around the MAF have anything to do with the fuel gauge, or does the level sender loom run straight to the back of the instrument cluster? Link to post Share on other sites
mannie 0 Posted October 1, 2007 Report Share Posted October 1, 2007 Faulty sensor .No need to "hack" the MFA for mpg , the in-dash display already shows you mpg,oil temp.,distance travel,etc... Link to post Share on other sites
andybg40 0 Posted October 1, 2007 Author Report Share Posted October 1, 2007 I did change my fuel pump a couple of moths ago, maybe a wire has come loose. I'll check it later. Link to post Share on other sites
