I've searched for this both here and at Renntech, but can't find anything similar.

'99 Boxster S Tiptronic. MAF and AOS replaced in February.

I usually get 400kms from full tank of fuel to the yellow low fuel light. The fuel gauge reads about 70kms to go when the light comes on. Normal. I usually fill the tank very soon after the yellow light and it takes 57 - 58 litres. But after the last fill up, I only got 360kms. I checked the receipt and found that only 52 litres went in.

The next time, I drove until there was only an indicated 35kms on the fuel gauge. It took just 54 litres to fill it.

The tank holds 64 litres, so I reckon 5 litres is 'missing'. The fuel gauge looks full, but the needle seems to fall more quickly than normal. Also, my MPG seems to have gone up by 10%

Can anyone shed some light on this? Thanks in advance.
