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.
-
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 :sad1:
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 :driver: 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?
-
About 1mile town driving on my way to work the rest motorway
-
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.

/\ Normal, and my experience too.
I don't care about mpg and I never look at, or work out, the mpgs at different speeds and driving scenarios. I just occasionally look at the long term average (memory 2 on the stalk) and it's been 27mpg for the past 2 years. It's stage 1 tuned, 310hp. My mpg didn't change after the remap either, it stayed the same weirdly enough.
To give some context on how I drive:
My daily commute is a 30 mile round trip. Approx 3 miles of it crawling in traffic from cold (1.5 miles at each end) and the rest Dual Carriageways / country roads.
I give it hard boost pretty much at every opportunity I can, and my average DC cruise speed is 90mph. I do 70-80 on the back roads if there isn't a blue rinser doing 22mph.
It's a bit like my old R32. No matter how hard I drove it, I couldn't get the long term average below 26mpg.
27mpg I would say is good for a 310hp turbo engine. I think there is a misconception that direct injection's sole benefit is improved fuel economy, but it isn't unfortunately. It's mainly for cylinder cooling to allow a higher compression ratio to be used, which is useful with turbo engines. The particulates from DI are awful though, hence the black sooty tailpipes.

I have had my standard Eddy for 6 months now and was pleased with an average of 27mpg over about 3000 miles on menu 2. However recently I have been getting around 25mpg on my commute to work which is mostly motorway or fast dual carriageway. However I am attributing this to a few things but I get about 350 miles on a tank fill of about 55 litres. I did get about 33mpg on a long run once
- Dodgey thermostat which always goes up and down between 90 and 80. You can see the actual engine block temperature is only running between 68 and 78 most of the time on the secret aircon values, number 19.2. Push Aircon and Upper vent buttons together and rotate Left large knob for 19 and middle large knob for .2
- Rear brake calipers which are slowly seizing up I think and need sorting. Squeaky and the discs are getting a little darker and not bright silver so constantly rubbing a bit
Oh and soot... you would think its a diesel from those tail pipes :grin:

I had 1. and 2. on mine as well.
1. I did myself and 2. the main dealer sorted for me 'whilst it was there' getting a service. I asked them to look into the back brakes squeaking, and their fix was to replace the whole lot :grin: Calipers, carriers, discs, pads & hoses, all of it! Pre-empting my shock at the bill, they did say the calipers were beyond rebuilding with new seals because the handbrake mechs were completely seized solid. Standard Golf!
The result of all that was getting 1mpg back :grin:
I don't think I've ever seen 30+ from mine. The most the computer says I will get from a tank is 320 miles. I think it's just accepted my foot is made of lead. It probably won't bother in future. I'll fill up and the miles left screen will just be laughter!
Yeah I got a much cleaner exhaust from port injection. Direct injection is harder on engine oil too, tonnes of soot clogging it up, as well as washing it off the cylinder walls, not to mention bunged up intake valves. Awesome bit of design that!

I would check rear calipers and MAF, the MAF can be cleaded with carb cleaner, if you're carefull, made a huge differnece on other cars I've had.
My MPG went up a bit when I changed my rear calipers, as one was sticking.
in My Ed30, on a good (legal) motorway run I can get a shade over 36mpg, round town and pootling about it can go as low as 24, but usally 28. does seme to use more in the cold weather though.
