The gas gauge on my '04 sedan reads about 1/4 tank lower than actual level. For example, when the tank is full, it says it is only 3/4 full. I just bought the car last Saturday and didn't notice it at the time. Is there an easy fix or way to recalibrate this?

Also, the light on the clock is not very bright. The owner's manual has great instructions for replacing most of the bulbs in the car, but not this one. Any suggestions?

 

Try different pumps. For me, if I go to Costco I can get a full tank. Something about the local SuperAmerica only lets me get 1/2 a tank. You can also try turning the nozzle sideways, or pulling it out an 1/8th of an inch or so and filling it that way.

 

yea this is a common problem... mine does this too... its not a problem with the gauge ... most of the time its a problem with the tank/valve that doesnt let the tank fill to capacity

mines been doing it too, so ive been searching for answers... i havent tried keeping the nozzle halfway out yet, but I will do so the next time I fill up

 

Yep I have had the same problem with my 04 cpe, I took it to the dealership when it was under warranty but that ONE time the darn thing did not had any problems

 

If you refer to the G35 1st generation forum......there is a posting on there about 7 pages long that talks about the problems that we are having with the fuel gauge.

Check it out, pretty helpful information and you'll be able to pinpoint what's really going on

 

sometimes my siht dont even work...
I know I have half a tank... but the damn needle goes all the way past E, making the light come on.
I fill it up 2 gallons to test and it goes back up to half... I need to fix this siht too...
Any links?

 

OP is talking about his gauge not showing full, NOT the TSB about ot able to fill the tank.

The gauge meter is in the gas tank and i have this issue too. It's common but I dont know how to fix it.

 

There is a fairly common issue on the G35 regarding the sending unit for the fuel level.
I believe there is even a TSB for certain year / production range models.
if your car is still under warranty take it in to a local dealer (OR us here! ) to have it looked at. If not, the only true way to fix the issue is NORMALLY by replacing the sending unit. There are two in the car's tank so you should still get it diagnosed before throwing money at it.

and as always we've got these in stock at discounted prices if anyone ends up needing one!

 

@ Tony ....I'm located in spain and its doing the same .....How much are the units? And how difficults is it to install.
