Filled up a couple of days ago and the needle went to it's usual 'above full' level.

Having driven around (a mixture of town and motorway miles), the needle didn't seem to move. Now it has finally started to drop and has gone to half way between then 3/4 and full markers. Trouble is, i've done about 80 miles now, and even on the best runs ever, i'd still expect the needle to sit at just under 3/4 full. Nothing has been changed engine wise, so no explanation for this.

As I understand the newage's (i have a 2001 bug) have two senders. One that does 0 - 1/2 and the other 1/2 to full. Is that right?

Does anyone have any idea why the needle might be going down so slowly? I've tried a little 'percussive maintenance' and the needle didn't move.

I could understand if the sender was fubarad it would read at half full or empty, depending on which sender was or wasn't working. But to stick at full, then very slowly drop? What could be wrong.

I'm going to fill it up to the top again and see what happens (I have a long road trip tomorrow), but knowing how my car likes a drink, there's clearly something wrong.

Anyone know of any common issues on this?

thanks

None that I know of, I'd be interested in the mpg result when you do fill up.

I've had cars that the gauge will SEEM to stick, then drop like a stone after being turned off for an hour.
Once happened to me towing a caravan at 2am in France. Approaching Dover the gauge read over 1/4 tank, EASY enough to get to the first fuel station on the A26.

As I got OFF the boat, however, the fekking fuel light came on..........it ran out four miles short of the garage.

Never had any issues before with it staying so full for so long (hell, if it's right i'm certainly not complaining!)

Car has been turned on and off several times, and left over night etc, but still, the same problem.

Most odd!

only one sender/float. They often take longer to go down from full, as once the float has reached its top level more fuel can still be added. So the float may not move at all for the first maybe 5 litres of fuel used. People often say of all makes and models that there cars use less fuel when there full. Its a trick of the guage and mind.

Figured it out. I'm a retard.

I'd isolated the battery a couple of days before filing up, which zeroed the odometer. Like an idiot, I didn't reset it when I filled up, then forgot how recently i'd filled up.

New tank of fuel, no gauge worries.

Sorry all for wasting your time. Feel free to mock!

My gauge doesn't seem to move much for the first 80 miles or thereabouts - but then it soon drops off.

I fill up at around 175 miles.
It usually takes around 37L.
Average approx 22 mpg.

(although I have had 26 mpg - freewheeling )

(car = 2002 wrx wagon. all standard atm except for an induction kit type thing).
