Fuel gauge - 156 Tspark

Hi Guys,

apologies if im posting in the wrong area, as im a newbie im still learning (this is my first post), Ive jsut bought a '01 156 and the fuel gage is broken, I bought the car on Saturday and when taking for a spin I noticed it needed a top up and the previous owner was at the garage with me told me not to worry the gage was a bit slow to come up once filled, but its full to the brim and the petrol light is on and registering as emtpy, so basically what im asking is it a fuse problem or is it the float in the tank that needs fixing,and if so what can i do about it? any help or advice is much appreciated . .

I have noticed that if the ignition is on when the car is filled up, you then turn the ignition off to start the car, the guage will then take an AGE to register. It slowly creeps up but only once the ignition is on and only when the ignition is on. I reckon it took well over an hour for it to show on the guage.

Mine did that for about 2 weeks, 2 years ago. The guage just dropped off to show empty and the light came on permanently.

I kept putting off checking the connections until one day it just started working again! It's been fine ever since too. Drive it for a bit and see if comes back on.

Even if the fuel guage is working, don't trust it, they lie.

For the gauge to be accurate,the engine should be switched off when refuelling.

Re: Fuel gauge - 156 Tspark

I had this problem last year, I had a fiddle with the cables underneath the rear arm rest and it started working again ...

I suspect there are pixies at work. When I parked my car at work yesterday the light was on and the needle was almost resting on the stop. It seems though, that when I park facing uphill, or with the offside wheels on a kerb, pixies put more fuel in so that I have enough to get home.

Re: Fuel gauge - 156 Tspark

I wouldn't be too worried!
The petrol guage is notoriously inaccurate. I've had:

Orange light and needle at stop for over a week, go to fill up and still had nearly 15 litres in the tank.

Just filled up, read as empty for nearly 20 miles.

Gauge going down as fast as speedo going up - then suddenly stabilised.

Gauge increasing gradually over a long trip - despite not putting any more in the tank!

Unless it stays like that for a very long time, I wouldn't be too concerned. It'll figure itself out eventually - just maybe keep a full jerry can to hand
