Had my Karoq a couple of weeks now, and love it, but am puzzled by something that I'm beginning to think is a potential problem.

 

I can only fill my fuel tank to 88% full (according to MySkoda app) and the fuel gauge in the car shows it being 7/8ths full.  That's with moving the pump nozzle around and trying a few different fuel stations..

 

Has anyone else encountered this??

 

Thanks

 

Very probably; like pretty much every other Skoda in the history of "accurate fuel gauges" the pressure cut-off leaves an expansion space at the top of the tank.

My brand new Octavia was similar. Had to have a whole new fuel system put in because the sensor was foobared. 

I see the OP has a Diesel, but be careful be it diesel or especially a petrol not to 'Vent' the tank before parking a car up, and even if doing it to extend the range while travelling.

I fill the tank of my Karoq 1.6TDI SE till the filling station pump stops - tank full.  Gauge always on the max.  In fact it takes approx 40 - 50 miles for the needle to start dropping from the max.

Hope this helps.

Might be different on your Karoq but my experience of many Skodas is that the tank is nowhere near full when the pump senses back pressure and cuts off, if you are patient, and you need to be very patient you can get another 7 litres in.

 

Same deal when the guage reads empty and the MFD shows zero miles there is a 7 litre reserve capacity beyond that.

 

People who fill up promptly when the warning light comes on (and it is annoying as mine bongs and flashes) and stop when the pump cuts out are not using even half of the actual range of their vehicle.

I find with some pumps (mainly Sainsbury's, but there are others where this happens) I have to twist the nozzle as much as 180° to fill up completely, otherwise the pump clicks and won't dispense any more fuel even though with the 180° twist I can still get a fair amount in. 

 

The only thing to be aware of with using this method is as the nozzle is decanted at an angle the auto shut off doesn't always function. To great around this I just line some service station provided blue roll under the nozzle to catch any overfill. 

 

This is the first vehicle I've experienced this with,  so not sure if it's a VAG design issue or a diesel one. 

I have to withdraw the nozzle until just the tip is resting on the lip and then dribble the fuel in, this disables the pressure sensitive shut off system.

 

People get fed up with me in the filling stations but it gives me another 100 mile range and means less fill ups per year.

 

It was much worse when I moved to France with my first TDi because then they did not use the defoaming additive that the UK did, no difference between the fuels now but the filler design is just as crap on the MK2
