Can you not trick the fuel computer anyway.... Get the engine up to temp sit at 55mph or so the instant fuel economy reading is very good then hit the re set button on both of the 1 and 2 settings... I think this alter's the computers tank range figure...
Haha, yeah but you don't actually get any more miles to the tank!
Really... LOL... not what I was getting at... But if you have a very low average over a lot of mile's I think the computer uses that as a benchmark for the range it will show. Has the OP tried re setting it ?
Mine is about the same as RR ... Also dsg, Maybe a tad higher on longer runs 32 ish...
Always looks good when you come to sell a car..... look sir she does 39 MPG round the town
