My GTi has decided that it is only going to do 250-280 to the tank, which give me an average mpg of around 26-27, this is far to low and i have no idea what is causing this.

Can anyone help?

thats about right mate, i get 300mile to my 1.4 16v

Lowest i've ever seen is 32mpg, think you may have a problem. Can easily see 350 from my average tank, don't know what to suggest really, sorry!

If I hammer it everywhere I only manage about 250 miles on a tank...

If I drive normally... up ot 75 on the motorways.... I get about 350 before the light comes on...

If you have access to VAG-COm, get it plugged in and check for error codes...

Are you sure the tank is filling right up>?

250-280, is that before the light goes off? I see anything from 270-300 before the light comes on, which equates to around 31-35 MPG

Mine's no better than that really, typically I reach about 280 before the light comes on, that's doing 99% town driving but I guess i'm not the most economical driver.

What bothers me the most is the fact that the car seems to be quite slow unless i get it upto around 4k/5k revs, is this normal or is it just my mine?

The VVT kicks in at 4.5-5k, that'll explain the power surge. it's hard to say whether yours is underpowering though. As one mans slow is another mans fast.

Think there may be something up with mine too then.
when the car was standard i only got around 250 to empty. now i have a Bmc and straight through exhaust it only got 220. somethingh wrong with mine.
and sorry to sound stupid but VAG-COM?

I rarely get less than 300 miles to a tank, that's with my foot down a lot of the time.

Its the VW diagnostic system that gives you an idea of what (if any) electrical modules are damaged...

If you put your location in your profile a local person in the know might be able to help you!

Normal. To be honest you could say it's like a normal 1.6 up until that point. If you work it up to the redline in every gear it's brilliant, especially the noise with the BMC. Even without a BMC it sounds good. Although peak torque is around 3300rpm, it's still good going from 45 in 5th at around 2200rpm

hmmm the one drawback of the 20v....i used £30 on saturday alone! i think i get around 200 miles to a tank if i hammer it

I get about 290 - 300 out of a tank and thats heavy footing it everywhere.

It is much better on motorways runs though and can get up to 350 miles from a tank on constant motorway runs.

This week I've been taking it easy to work and back (70miles a day) And I've just got 330miles before the stupid light came on. I'm well chuffed. I normally get about 270 before the light comes on, that's errr not going slow.
