Help with bad MPG

[golfmck1980]

So ive had my eddie just over a month now and been getting really bad mpg atm im getting 20-22mpg driving like miss daisy and free wheelin every where lol. My work is only 9 miles away which is mostly motorway which i usually only sit at 60mph on. So basically what do i need to check engine wise cause ive heard some guys getting near 35 in the same situation

How are you working out that mpg? On the car display?

Best bet is as soon as the fuel light comes on, say stick 20L in exactly, and then when the fuel light comes back on you will know how many miles those 20L have gotten you. Then you can work out the mpg.

I find the car mpg computer useless unless you reset it on the motorway whilst diving and leave it on for at least 50 miles.

Also remember the temperatures have plummeted so this will have an effect on mpg.

I know the weather has got a lot colder but it was still the case when we had the warm weather cause i rem leavin work and the car was reading 15c outside. On my return from work most days i can nearly see the fuel needle steadily drop been joking with the guys at work saying someone had shot a hole in my fuel tank

I would clean the MAF sensor or unplug it to see any difference,I get 100 miles for twenty quid.

What's the temp needle doing? I'm getting this in mine and it never stays solid at 90, always fluctuating lower than that.  This is the main thermostat and is a bitch to do. It causes bad mpg.

I'm going to try and find a guide to do it myself but chances are I'll get someone else to do it whilst it's this cold.

[golfmck1980]

The needle goes to 90 and stays there so no problem that way

I had my thermostat changed as it struggled to get to 90 but I also changed a rear caliper that was sticking and now my mpg has gone up significantly so maybe check the calipers as it seems a pretty common thing now

Okay will check the brakes but it does free wheel quite wheel sure if a caliper was catching it wouldnt free wheel as well as it does

I've had really bad MPG from my car since I bought it. I've tried.....

...checked the tire pressures
...changed the spark plugs
...changed the coils
...cleaned the inlet valves
...replaced the thermostat
...serviced everything
....Etc etc.
I took the car for a careful drive through the countryside and managed 40mpg on that (very careful) run!

But day to day I can't manage any better than 20mpg

A lot of my driving is town based. But still. 20mpg sucks. I get an average of 320mls from a full tank.

I was expecting good things from the GTI but so far the car is no better than my previous 155 V6 or Subaru WRX....

Anywho.... I've decided to give up worrying about it

Some shocking mpg in here, my old mk5 gti when taking it steady I could get into the 40's and around 28 onwards when giving it some beans. My new mk6 R is normally sitting around 21mpg at the min  it was doing 35.5 on the motorway bring it home

I'm also getting around the same mpg on my eddie

OK well 2 things against you straight away, winter and a short commute.  How much of that 9 miles is town/city driving?

[golfmck1980]

About 1mile town driving on my way to work the rest motorway

[jonnylaris]

I was just about to make a post and saw this one. I'm having the exact same problem. If I'm on the motorway I get 30-33mpg but town driving I get 20-22mpg and if I really take her for a proper blast I get 15-16mpg...

Wondering if this is just normal for ed30's?

For reference, I've replaced: PCV, DV, Coilpacks, Plugs, brake calipers checked and replaced 1 that was stuck, new ps4 tyres all round.

I'm running APR stage 1 but the economy was the same before I had it mapped.

My stg 2 eddy returns very similar under these conditions. Will drop to 28 ish at 85 on mway.
Personally, i think that is fantastic for a car of the size/type/power. It is a 5 door family hatch at the end of the day...not a svelte sports car.
As for range, lucky if i can make home to Blackpool (350 mls, do this once a month) on a brimmed tank, so i think some of the ranges figures quoted above might be a tad optimistic?

I have no idea what it returns around town, and don't see that as important, or indeed relevant.
