This is something that's been bothering me for a while now. Whenever I fill up I just usually put £20 in (more if it's cheaper than other shells) of VPower. I'm lucky if the £20 of VPower gets me 60 miles till the light comes on? I find this very odd as I'm driving very sensibly and hardly ever on hard boost. My Type R gets more miles to £20 than the golf and that's when driven hard too....
Does anyone else get similar mpg to me, usually when I'm driving the trip computer says around 16-18 mpg :sick:
-
Car is completely stock with all services up to date and all recalls carried out too
-
hardly ever on boost and only getting 16mpg? you have issues of some sort. I get 30mpg commuting and thats normal driving and traffic.
Mixed driving with putting my foot down at times i probably see low 20's at worse. Would only see under if constantly putting foot down.
I dont get many miles to £££ because of price of fuel :( Think i put £50 of momentum in and do about 220-250 miles
-
no that is shocking, if you really want to check the range per tank then you need to fill the tank up to one click then run it for awhile longer the better for an average and then fill up again and log the miles and the number of litres used to reach the first click off again that will give you an accurate mpg to check what the computer is saying. but I personally see around 30mpg round town and get upto 36-37 on long runs and can get 400miles to a tank which is £60 of v-power.
-
I just use standard 95 RON and get 35mpg average. I put £70 in and it has done me 300 miles or so. Sat in traffic quite a bit and not too shy of putting my foot down.
-
ill try and convert, but i usually average around 8litres (35mpg) per 100k, and i do probably the EU test as my daily drive, 15 min in town and 15-20 a roads and highway.
its more fuel efficient then my 1.6 alfa, and i drove the alfa harder then the golf
-
seeing about 24-26 mpg on stage 2+ on short journeys, so to get less than 20mpg something is not quite right
-
It's ridiculous I'm getting such low mpg, any ideas what could be causing it? Maybe a leak in the exhaust? So best thing for me to do is fill the car right up and then drive till the light comes on. Then from that I can see how many miles I'm getting per litre and full tank?
-
Could it be something serious, confused to what it could be?
-
I was just suggesting that the computers can be out on what they say so if you want to calculate manually then you need to fill the tank to a known level (full with the pump clicking out) then drive for any amount of time but the further the more of an average you will get, then fill up to full one click again and then take the mileage covered and the litres to re-fill (so you know how much you have used) to calculate.
Its just worth sanity checking your computer figure of 18-19 mpg. as I am not 100% that the low fuel warning is based on fuel volume or range if its range then the low mpg reading will be causing the computer to think you will run out before maybe you are.
If it is that low then you need to get the car checked over I guess things like cam follower fuel system (check no one is syphoning your tank) that sort of thing :laugh: not sure how it could be exhaust related.
-
I'll wait till the lights on next and then fill up. From that I'll be able to work out what sort of mpg im getting. I'll update soon. Thanks for the replies
-
No point putting £20 fella, fill her up as the other guys have said! I get 30mpg average! 400 miles to a tank if driven carefully, filled up with v-power the other day £76!!!!
-
So just drove home from work, around 5.5miles. Drove under 3.5K RPM all the way with no hard acceleration and guess what........19.1MPG according to the trip :sad1:
I was granny driving all the way and still under 20mpg? How can this be? Will fill up tomorrow and see how it go's. It can't beleive it tbh. Even with a full tank I can't see it making that much difference surely?
-
It sounds like the car is running on cold start all the time, it could be something as simple as a temperature sensor making the ecu think the engine is cold. :smiley:
Its just a guess though i should add. :happy2:
-
If that's the case would the engine not also idle quite high? Although this could be the case how's best to diagnose the fault?
-

I honestly dont know the answer to the idle question, but i would guess that the engine would run rich longer than the 30ish seconds of fast idle on start up. As for diagnosing the fault, there are some VCDS (vag com) experts on here that could point you in the right direction on which blocks to log to see if you are running rich all of the time. Alas, i'm not one of those experts. :sad1:

Hopefully will get one of them check this post :jumpmove:

£20 gets me not far off 100 mile.

VPower? Also town driving, motorways or mixed?

Its not driven like a granny its driven on long runs at legal speeds, and I have added body panels from bluemotion and TT which took me from 340-360 range up to 400.
The high revving at start up is to warm the cat at that time it double inject per 4 stroke cylce once when it should normally and another ready for exhaust vents to be open so that EGT temps will help the cat to meet emission temps as soon on start up as possible.
-
I just had the same problem, turned out to be air mass sensor, £124 fitted, solved the problem straight away, see if you can get someone to check the airflow for you, it should be above 200 ( so I was told)
-
Hang on surely this is about right. £20 60miles light comes on and states 50-40miles left to empty? So all in when the trip gets to 0 a 90-110miles would have been driven?

Don't know whether it's just me but the last half of the tank does go down faster so if you are only putting £20 in at a time that could be part of the problem. Not sure if its due to the curvature of the tank or what. In fact if I fill the tank up full, until the pump clicks off I can get about 60 miles or over before the needle even moves :-)
-
you get all the fuel in the pipe that feeds the tank before the sender can even move. And despite running down to 5-10 miles on the range you can never get much more than 50 litres into the tank so even when the light comes on you still have some 5 litres of fuel or just over a gallon in old money.
-
i'm assuming my A3 has the same tank as the Mk5, but i can push just shy of 60 litres into it if it's been running on fumes. (qutoed tank size 55L.) i get about 40mi from the fuel in the filler pipe before the needle wears down.
i thought the 28mpg i get was bad :confused:. on motorway runs it's quite difficult for me to get decent fuel mileage if i stray anywhere over 70mph.
-
I'm going to fill her up today and go for a long run. See what mpg she returns. According to a few other GTI owners they seem to think around 20mpg is normal in town driving. On the other hand, when I fill up £20 the trip says I have a 90 mile range but it always turns out to be more like 60 miles :laugh:
-
the remainder of the 90 miles quoted is the red light, its 90 miles to empty not till the light comes on :happy2:

What parts have you added that increases mpg so much?
-
And I remember the days when VPower was 98P per litre, even tho fuel has went down in price to the government it's increased to us :stupid:
-
saw an old photo of my dad with his Lorinser 500 SEC and a petrol station in the background. almost cried at how cheap it was compared to now :sick:
-
£20 gets me not far off 100 mile.
VPower? Also town driving, motorways or mixed?
v power,mixed but taking it easy no heavy right foot.
-
Mines awful too, just bought it last week and around town I'm getting around 15-18mpg and not really booting it. Only had it a week and I'm already considering selling it for an ibiza cupra tdi as i just can't afford to be putting that much petrol in it!! Did you ever find the problem?
-
NO offense meant to anyone here but if you buy a GTI (Sports orientated car) then MPG was clearly not a concern :surprised:, if your concerned about MPG buy a diseasal :happy2:
-
^^^
Was thinking this. Although mine is usually above 20mpg even when putting my foot down so sounds like something's not right with the OP's.
I don't use my GTI for commuting so MPG is not really an issue for me and the excitement I get when I put my foot down more than makes up for it IMO :happy2:

Same goes, work from home, so it's sat on drive most of the time, takes me to the golf club and to JKD lessons, most driving is "Spirited" when it gets on the road :happy2:.
6 weeks ago on my move from Norfolk to cornwall (408 miles) I averaged 34mpg on the journey (80 miles of A roads and 328 miles of Motorway/dual carriageway) :happy2:
-
You've said that your commute is only 5.5 miles. The car won't be warmed up until (if you're lucky) halfway.
Why not ride a bike - save money, get fitter? 5.5 miles would be a perfect distance. And it'll be better for your car, too.
And I wholeheartedly agree: you don't buy a GTI if you're concerned with MPG!

....Last week I drove a 492 mile trip and averaged 28mpg (on the display). The journey took in the A34, M40, A43, M1, and plenty of cross country roads. All on the fast side though.
Reported mpg figures really seem to vary a lot.

I completely ignore what the readout states, it's usually a load of tosh :signLOL:, I filler her up and work out my mpg, it is usually 10-20% different from readout on trip comp :signLOL:
-
^^^^
Well, I can't be arsed to work it out as it's not going to make an iota of difference in the way I enjoy driving nor whether I decide to keep the car or not.
-
Hang on that sounds ok. He does 60 miles before light comes on which is usually around 40miles. Making it around 100miles to 20 which I personally think that's ok if that's mixed driving
-
Is your trip computer showing on the average readout? (Circle with line through it?) I regualrly get over 30 mpg around town with my 2005 GTI and Ive seen over 40 on a run many times , driving on the speed limit or just below - I find driving at 80 plus on the motorway lowers my run mpg to the mid 30s. If normal town driving in a fully warmed through GTI is returning less than 20 mpg then there is something wrong with your car - either that or you are in constant traffic jams. Even when that happens to me i still get high 20s and once traffic is flowing again its back up to the mid 30s in a few miles.
MPG of a run from Berwick upon Tweed to Galashiels (45 miles) , mix of A and B roads , 50 -70 mph.

So if I drive with both doors open I get better MPG? :wink:

Stupid answer time
Have you reset the MPG meter to zero ? , right hand stalk bottom button hold until the mpg meter resets, you will be amazed what a difference it makes !!
Just a thought !!
