99.9 MPG on a 325i WTF???

wuufer001 · 01-19-2009, 02:11 PM

WTF, how the hell can i get 99.9mpg?
anyone?
the last mod i did to my car was the injen with the MAF sensor, thats all. and after the install it was all running perfectly and the BC numbers are all normal like 23.5 mpg.
did my car suddnely turn into a hybrid?

i resetted the MPG number on the BC and now it seems correct and not giving me this crazy MPG

I think you have a message...

Jimspeed · 01-19-2009, 02:13 PM

or you reset the meter, then started coasting down the road and flipped to it..took a pic.

Bilka · 01-19-2009, 02:14 PM

If you had just reset ur MPG, and your foot was off the gas while the car was moving, it would go that high.

wuufer001 · 01-19-2009, 02:17 PM

no guys, i haven't resetted the MPG before, only only did it after i saw the 99.9mpg
can anyone tell my what may have went wrong?

ejazbmw · 01-19-2009, 02:17 PM

lol this happens to me a lot i guess because i ride in neutral while going down hill

wuufer001 · 01-19-2009, 02:19 PM

no again, this was not done intended.
i haven't resetted the MPG since i got the car, only the dealer i think resetted once before and that was a quite a while ago

So if you reset it and drive normally, what happens?

JL330i_UT · 01-19-2009, 02:31 PM

ive seen that on my car numerous times. it only happens after i reset the obc.

Sara · 01-19-2009, 02:35 PM

Driving down the caynon I've seen it at 99.9 before in a 335i.

You know... If you left it in gear instead of putting it in neutral it would actually use less gas. While in neutral, the fuel pump needs to pump fuel to your engine to idle. If you leave it in gear, your fuel pump doesn't have to do anything if you don't have your foot on the gas pedal.

Just calm the f* down... If you really want to worry about something, worry about how you can reduce your picture before you post it.

doing that will cause the opposite, a tendency towards 0.0 mpg...i think you're mixing up mpg with l/km

It is called fuel cut off (coasting in gear).

Aurora Bearialis · 01-20-2009, 04:17 PM

Well there's one MPG that tell you your entire MPG and then another one that says your current MPG. If you take your foot off it says 99.9 if you step on it, it goes down to 8 or something like that. You were probably on that reading, not your entire MPG.
