First noticed when gauge was on half full, then 'bing' only 40 miles left!

I've watched it closely since then and once, going uphill(!), it increased?

I filled up today and fiddled (As you do) with the nipple at the top of the filler pipe and loads of air came out - good?bad?dangerous?

From Briskoda research you can lift the rear cushion and get access to the fuel pipework.

I will check and clean the pipework but is there a specific fault - i.e. some sender part?

Thanks

Matt:confused:

I've got a 2000 Octavia 1.6 and it does the same thing - except between half and 3/4 empty it will go down to almost zero and then later settles closer to the actual value (I reset the trip every fill so I know when I need fuel). Its almost as if its taking a reading every half hour of driving and just happens to take the first reading when I'm going around the same sharp bend every day, so gets an artificially low reading!
