My Yeti just reached 10000 miles, overall good, please see other thread for report.

I noticed in the last 2 or 3 fill up, when I fill her up to full, the needle doesn't register full any more? I did the same tonight, fill her up twice, actually, first one took, I stopped after the first clunk on the nozzle. Tried to go for a second clunk and it wouldn't let me, after going shopping at Sainsbury, went back to the fuel station to have another goal and all it could take was 1.7 litre!

I also heard fueld gushing and upon investigation it was definitely full. I then drove it for a while, turn off the engine and start again, it doesn't register full! Anyone have any idea what I am dealing with, or am I just being paranoid.

Just to add, the trip computer says I only have 415 miles to go in the tank, when it normally register 475 or above!

Thanks in advance!

Edit: The tank was actually 7/8 full at the time, and by putting in about 7 litres, that adds up to about 56 litres max - close to the 55 litre designed for it, so would that be a duff sensor or duff gauge?

The answer to the three questions paranoia, gauge and sensor, is "possibly", but that does not help you much.

I suspect that it is not the gauge, but either the level sensor or an overenthusiastic shut-off setting on the fuel nozzle at the pump.

You do not say how much the gauge is off, but if just a hair, forget it. Since this is not a lifethreatening situation, keep an eye on it and if consistent, talk to the Skoda dealer at the next opportunity.

Hi,

It is off by 1/16, quite noticeable, half of 1/8.

Thanks

I wouldn't worry about it too much; I tend to use the gauge as a guide rather than an accurate measure. I very much doubt that the graduations on the scale actually represent precisely equal quantities of fuel in the tank.

The fuel gauge needle on my previous car was always sluggish to register full. After filling the tank it would never actually be showing as full on the gauge by the time I was driving out of the petrol station, but a few miles down the road it would usually have caught up with itself.

I filled my Yeti last night with the range showing less than 30 miles and the "please fill me up" beep sounding every time I started the car. It took 50 litres, which means that there should have been around 10 litres left in the tank which should be good for more like 80+ miles. That's another example of the relative inaccuracy of the gauge IMO, and a likely reason why the remaining range estimate is likely to be off. Another reason for the range estimate to vary is if you've just driven a short way to the petrol station to fill up: the fuel consumption on that short trip will likely be poor compared to your overall average, and I believe it's the more recent consumption rather than a longer-term average that it uses to calculate the range. (You can judge the effect that short-term fuel consumption makes to the estimated range by deliberately driving in an inefficient way eg holding low gears for too long, and observing the impact that has on the range estimate.)

Another thing to bear in mind is that some of the cut-outs on the fuel pumps can be over-sensitive. On my previous car I could usually get in a useful top-off at least twice if I just waited 30 seconds or so after the flow had cut off - and without needing to pull the filler nozzle part way out. It just took a while for the fuel to drain past the baffles in the filler pipe down to the tank when the level was near the top. Also, certain pumps would cut off the flow after just a few seconds, presumably because they interpreted a small amount of splash back in the filler pipe as a full tank. BP stations seemed to be the worst for that. The only way to get even close to a full tank was to hold the nozzle part way in and at an angle. (In retrospect I should probably have complained about it, because it must be less safe dispensing fuel that way.)

The diesel pumps at the petrol station nearest to where I work seem to be a little too sensitive for the Yeti's filler pipe, but not by as much. On the plus side, it's widely known to have the cheapest fuel station in town. On the minus side, that means it's always busy!

I actually found the fuel gauge in our Yeti to be both both accurate and linear (12. TSI). The total range was usually in the vicinity of 800 km (~500 miles) and every major "tick" on the gauge represented 100 km, with the smaller the giving me 50 km and 25km respectively. When filled up the needle showed full tank, after 400 km it showed more or less half tank etc. Never had a fuel gauge that accurate before, and it was concerning at first when it immediately started dropping. My previous cars would give me ~150 km before the needle moving at all

If you do feel that the needle is really off I remember seing something ine the VCDS software about correcting the needle position (I might still be wrong on this one, but I think I'm not), so you might want to find someone near to you with the cable to check things out. If you happen to be near Helsinki I'd be glad to help you out on this

Hiya,

Thanks for the replies - much appreciated!

I just want to clarify that the fuel gauge does could not register to max, nothing to do with mpg or average mpg computers.

Anyway, it turns out that it is my Yeti that doesn't like pump number 4 at the local sainsbury's (I always go for the same pump, well try to anyway) and doesn't like pump 2 at tesco's. As I filled up in Shell today, it took a massive gulp of yummy unleaded and it was so happy that it wagged its fuel needle all the way to max!

Cheers anyway - everything is sorted now!

If you know your going away on a long trip you can cheat and use the expansion tank to put in a little extra for the journey. If you look into the fuel pipe you'll see a little knob sticking out the right hand side just around 1" inside, you can push this down with the nozzle to open up the expansion tank and put some extra in for your journey. Not worth doing on normal fills as you'll use up the expansion area and probably end up losing fuel as the temperature fluctuates during the day as the fuel has nowhere to expand into.

I used to have a similar fuel gauge problem with my Seat and was told it was because I had overfilled the tank and the float had stuck. In my case, the electronic read out would say that the tank was full when it held a lot less. I was always worried I might run out of fuel.

Just done a longish two day trip totalling 500 miles in my Yeti and got 50 to the gallon even at 70mph, thought that was quite good as I've only got 600 miles on the clock so it must be a long way from being run in.

Brilliant! Never knew of the feature before, thanks for the msg, will take a look.

Thanks! I think the Yeti's fuel gauge is acurate - ie the miles you do corresponds to the needle movement. In my old car, it would not move until 100 miles, by then it moves very quickly.
