How accurate is the fuel guage?

[Daz Auto]

All mk 7s have a 50litre fuel tank period!

Did you read "Reply #12" above? My manual and the Golf brochure (UK) say you are wrong! (see reply number 12 above for details).

So we know for a fact that some VAG cars have 55L tanks. The question is: as I put nearly 54L in my GTI Performance with almost no miles on empty/reserve, could the Performance Pack cars have the same 55L tank which is fitted in the Golf R?

I stand corrected. My manual (MK7 R) states that all petrol/diesel MK7 Golfs have a 50L tank but the 4WD variants (i.e. the R) has a 55L.
This is assuming the manual is any more accurate than their brochures of course.

As I said earlier, the Audi A3/S3 quattro has the same 55L tank.

I would say very unlikely but who knows.

Why would you pay any attention to what the UK brochure says and yes I did read the post above thanks. What ambient temperature was it when you put your fuel in? Lots of things could have an effect on how much you can actually fill up

What about the manual? Should we ignore it too?

omg... lol... @'What ambient temperature was it?'

Unusually for the UK, we actually had a very pleasant warmish weekend. I seem to recall saying to my wife, "look it is still 19.5C" just before I filled up at 8 o'clock on Sunday evening.

It is just confusing me. I always like to know how far I can go on empty. I think I need to try a few different petrol stations, just to check if this is some sort of anomaly.

Here is the part of the receipt -

Are you some sort of know it all?? If it's cooler you'll be able to get more petrol in your tank than you would if it was warm. Why did you feel the need to make a stupid comment about the ambient temperature? You appear to have some sort of issue with other people commenting on your posts and that comment not being what you think is acceptable.

... well lets see... you are clearly wrong that all Golf's have 50L tanks. Even though it was discussed and you were the second person to get it wrong.

Then you start discussing ambient temperature! You realise how insignificant ambient temperature would be! Especially in the UK where we have a moderate climate. Never mind the fact that the petrol is stored below the frost line where the temperature remains relatively constant all year. Seriously???

Yeah, I thought this was obviously rubbish -

"But filling stations typically store their gasoline in underground tanks, where the temperature variation during the day is much less than in the air above. The result is that the temperature of the gasoline coming out of the fuel nozzle varies very little, if at all, during any 24-hour stretch at any particular station."

I've used OBDEleven to turn on the 'refuel amount' option in the dash display - be interesting to see how closely this predicts how much fuel it will take at the pump.

Not very, mine was over a gallon out.
