After driving my 2002 S60 AWD for about a year, I ran into an unusual situation of nearly running out of gas when I should have been fine. On my commute home and only several miles from my destination, my low fuel warning light came on. I had previously driven the car 30-50 miles on this reserve light without problem. The car ran fine until the next morning when it would not start. I could not believe the gas was that low, but when I put a gallon in it started up immediately. It ran rough for a mile or two then was fine. The odd thing was that when I filled it up, it only took 16 gallons (where were the remaining 5 gallons?). Now if by some chance I let the tank drop to the point that the reserve warning light comes on, it starts roughly every time the next day. Also, I have never been able to put in more than 17 gallons at fill up time. I have never run out of gas again, but now I can't let the tank even get low for fear of running out since I have no accurate way to judge how much fuel is really available based on what the instruments say. It seems very odd and cumbersome to not be able to use the low fuel warning. Has anybody else had this experience? Thanks.

have you made any progress with your issue ?

hi,
if youve got a problem take it to your dealer as its under warrenty anyway.
and for goodness sake put some gas in it and dont run it so low!

depends on the dealer
many of us use this forum to find out others' experiences, before going to the dealer, who (if dishonest) may, as in this case, for example change the whole tank, pumps in the tank, claim that fuel filter gets clogged etc etc etc.....before actually upgrading (cheaply and quickly) software for the DIM ?!
if you have an idea about the mentioned problem let us know

I thought somebody might have an answer to why I can never get more than 16-17 gallons into a tank that is listed as having a capacity of 21 gallons even when trying to "top it off" (something I know one should not do). It is also odd since the first year of operation and driving under the same circumstances this never happened. I drive on California freeways where it is not uncommon to have exits 20-30 miles apart. I also sit for an hour unexpectedly at bridges and toll plazas. Therein lies the problem of unintentionally "pushing the limit" of the tank. It just seems the reserve light comes on too soon (not even near the red zone). I would think that the calibration or sensor might be off were it not for that nagging question of where the remaining 5 gallons have gone! I realize that letting any tank get low risks getting sludge into the fuel filter, but now I have no accurate way of knowing when that will be likely to occur. Thanks for anybody who has had similar experiences.

Are you sure it's a 21 gallon tank? The 2004 S60AWD has, I believe, an 18 gallon tank. Did they change it over at a model year changeover to a smaller tank?
