hi ppl, just a quick one, my w reg 2.0litre gti, is oh so very poor on fuel, it runs and drives great and have been driving it as normal the past week, now ive past the new car thing of giving it a bit.
Put £20 in last week and its only done 70 miles!,jesus my old 4x4 used to the same :(
i know its a 2.0litre engine, but thought about 100 miles to £20 would be at the very least i would be getting, i am wishing i did go the extra bit and get a gt tdi now :(
think i am getting roughly 20 to the gallon at the minute, not sure how many litres there is to a gallon, is it 4.5 ????
like i said it runs fine and am pretty sure its had a service in the last 5000-6000 miles.
any ideas what it could be??

20mpg is not normal.

I get 24 - 28 when driving around town in traffic. When I'm on the motorway its 30+

I had a problem with my O2 (lambda) sensor which caused me to run rich and was giving me 16 - 19MPG. This caused the engine managment light to come on and when sitting in traffic produced a strong petrol smell (because of the rich fuel).

There are a few things that can cause your fuel to run rich, by far the easiest way is to get that car plugged into VAGCOM and see if any faults are indicated.

Also have you got the computer onboard which tells you your MPG, average MPG, average speed etc ? Its a fairly good way of seeing what mpg you are getting rather than trying to work it out. Just leave it on the average MPG and see what you get.

1 UK gallon is 4.546L

i always think its funny when you petrol guys slate the TDI owners then moan about economy  :evil:

Put £20 in last week and its only done 70 miles!

assuming you paid £1 a litre, you've done 15.911 mpg IIRC the 2.0 8v is about 33 mpg so either you're ragging it everywhere or constant town driving.

My GT TDI 150 will average 52-55 mpg from a tank, so normally get 500-550 before i fill up  :smiley:

them 150 tdi, really do fly, my friend had one, always wondered what it would have been like if it had be chipped/remapped, what you reckon 200 bhp ???
i can live with 25-30mpg, but not 15,thats just crazy for a daily runner, my boxster does 25!

If your O2 is gone VAGCOM will pick it up. As I said in my earlier post rich running fuel gives of a strong petrol smell, give your exhuast a good wiff, but not too much.

you're looking at ~195bhp and silly amounts of torque, standard the 150 has more torque than a boxster, impreza and clio V6

change the turbo on them and you can happily get 260bhp for road use.

Andy, where do you live? If you're anywhere near Brands Hatch pop down next Wednesday, a chap called Lee has VAGCOM which you can use for a few beer tokens.
