Some of you might of noticed a couple of threads by me lately looking to get a more efficient car as I've taken a new job which involves a lot of town driving.
I cant think of a new car I want at this stage which I like as much as the GTI for the money I have to spend.
So anyway, im in a Mk5 GTI DSG....round town im averaging between 23-25mpg. Is there anything I can do to improve this to get it upto...sayyy 30mpg?!
Remapping? Removal of the Pre-cat? anything else? or do I just have no chance at all?!
-
Push it..?
Seriously though that's the best you are going to get around town tbh, even if you bought a diesel it'll still be relatively crap on juice on town driving (My old A3 2.0Tdi 140) would do 35mpg at best round town..
-
Buy a VW Up, and put a GTi badge on the bootlid. That wil get you a minimum 55 mpg.
-
I have a 2005 GTI manual, I used to average around 28 mpg but after a stage 1 remap by Revo and a pre cat removal, I know can easily get 33 to 34 mpg round the town. On longer runs I can get upwards of 45mpg when before it was around 38.
I would definately consider a remap if I were you. Obviously if you boot it all the tme your mpg will be a bit lower, but all round driving while still having a bit of fun, you''ll be pleased with your new mpg. Not only that but a big smile cos of the cars new alive feel.

well im looking at the same figures as you, im on stage 2, de-cat. ive been thinking for a while about getting terraclean. Ive just had a service and changed the oil i was using from 0w40 to 5w30 (not sure if that makes any difference) but i couldnt see a change in my MPG. problem with driving in sunderland tho is you can get pretty much anywhere in 10 mins! :smiley:
im going to give the guy a call tomorrow to book it in and will let you know if that makes any difference.
terraclean had recommended 2 garages to me, one an auto electrician and the other a window tinting place. on speaking to both of them i was asked if the GTI was a petrol. Clearly not filling me with confidence of even knowing where the fuel lines were i contacted terraclean who's UK boss replied to me giving me someone who is "technical" so thats who im calling tomorrow.

Hmmm interesting...so driven normally I could be getting a 5-6mpg gain which would almost get me to the 30mpg bench mark im aiming for...for some reason haha I would prefer 55 but thats never going to happen :signLOL:
-
i drive normally most of the time, but cant get it to 30. i think its the location of the driving you do also, as i live up a hill, a long climb so MPG will be lower generally than someone who lives on a flatter area.
how many miles you get to a tank when the refuel light comes on? mine is around 275-290 even if the range says 315 miles after fill up!
-
Im not sure actually, I tend to just believe the range computer...next fill up I will be sure to reset the mileage and find out!
-
Pup the tyres up to full load level
-
I check mine every two weeks
-
Most 200bhp+ petrol motors are going to struggle to get 30 mpg+ around town tbf, unless they weigh 600kg. ;)
-
Is there any chance you could cycle for some of your town trips? Only way I can think of to reduce your petrol costs with the gti around own.
-
At the moment I'm a averaging 40/41. That's including my final leg in traffic/town. If I go in for 9am, when I'm not shift working, I still get around 36 on the m25 car park!

im not complaining, i didnt buy the GTI with a misconception that it was economical. i absolutely love the car be it driving spiritedly or tootling round. its a great all round car too. i just want to keep it running in the best condition it can be in. Thats the primary reason for me to do the terraclean nearing 100,000 miles theres bound to be a fair amount of gunk thats built up. im looking forward to seeing the results!

If they use an induction cleaning tool then go ahead, but if they just use the red and black cans ,then avoid it, save your £100 as it will make little difference to your overall mpg.
It doesn't clean the part of the engine that is the part that can alter and improove your mpg.
I later proved that Terraclean did nothing to my intake valves when an injector was replaced and the inlet valves were still gummed up with carbon.

This is what i do, plus it keeps miles down.
I can get 32/33mpg if i use MY revo tweaked map (using sps turing boost and fuel right down) and leave her in D (DSG), no aircon, windows closed, carrying nothing in car bar me.
-
I average 31 mpg driving from London to Bournemouth each weekend although I do bomb it. I set cruise at 50 on m11 on Thursday as I had plenty of time just to see what I could get , it was 44,3 mpg and I have revo stage 1 map . Pretty impressed with that
-
That is impressive!
Im in Bournemouth too.
Unfortunately I need to use the car for work for ferrying clients around all day so the bike isnt an option.
I might give Revo a ring and see what they think I could get out of it with one of their maps...although they are bound to be a little optimistic
-
oh and also what psi is full load level?
-
Push it..?
Seriously though that's the best you are going to get around town tbh, even if you bought a diesel it'll still be relatively crap on juice on town driving (My old A3 2.0Tdi 140) would do 35mpg at best round town..
We won't help Steve I'm sure by saying I get more in the Audi nipping across town roughly 3 miles (34-37mpg) than I did the best combined figure ever in the GTI (35mpg), will we?
:evilgrin: :innocent:
The raw facts are though that the majority of owners haven't seen above 38-40mpg even on long journeys, around town 24mpg is a rough marker and the rest is somewhere inbetween. It's not a car or engine you can squeeze economy out of like you would a more recent diesel or TSI block.
Keep it well maintained and enjoy it for what it does :smiley:
-
To get the most out of the TFSI, use light throttle and try to keep it "off boost". 40+mpg is possible on a long steady motorway run (even with cruise control). Coasting up to junctions uses no fuel in modern cars so take your foot off the gas well in advance of junctions and traffic lights and keep off the brakes as a result. :happy2:
Tyre pressures, good fuel and a well serviced engine help, as does a good thrashing to the redline every now and again

From my recent 1040 miles trip :driver: :happy2:
2.5 tanks for the whole trip

anything you do to make the car more economical will cost more unless you're keeping the car for a VERY long time.
things you can do (in no particular order)
1. warm up the engine prior to driving (tho i'm not sure if the petrol lost by having it idling would cancel out)
2. only use the air con over 40mph (mythbusters did a test which showed that this seemed to be the point where it was more economical than the added drag from a lowered window)
3. economy tyres
4. blue motion aero underbody panels
5. remap
6. use V-Power/Momentum (though from my calculations the added cost is negated by the improved fuel economy)
7. do an IAM (or similar) course. it really improves your forward vision and makes a smoother (and hence more economical) driver
8. try and plan trips so you're doing several things at once in the most efficient fashion
the 2.0T is an impressive engine. when it was new, it was very economical considering the power that was available. just as a measure, i swapped from a 2005 1.6MPI to a 2006 2.0T and saw a 10% drop in fuel economy for a 95% boost in power. on long trips the K03 engines will see up to 40mpg (the K04s are a little more than this iirc because they're off boost for longer on long trips) but around town they really aren't that good and there's just not much you can do about it!
-
^^ warming up the engine before driving is the worst thing you can do for fuel consumption :sad1: engines are thirstiest when started from cold as the ECU is dumping fuel in to heat up the cat to get it working. Best thing you can do is start up and get driving (gently), the load on the engine warms it up and gets it to is most economical fastest.
An idling engine is just pouring fuel away, and your average mpg will really suffer

Sadly that's the cold hard facts of life with a gti mate!
Even at its worst (35mpg) my A3 was still 5mpg on average better than the ed30 on a run :surprised:

The TFSI was designed with economy in mind (direct injection etc). It's designed to run very lean on light throttle (FSI mode). It's getting the engine to go into "FSI mode" that takes careful driving. If a lot if us on here can manage it (loads of us can manage 40+mpg) then anyone can. Most people just like to boot it everywhere and say "it's a 2.0 turbo petrol" it's not about economy. . .
Power & economy (although bit at the same time), is what makes the TFSI so good :happy2:
-
sounds silly but have you checked your pvc and dump valve? When my partner got her edition 30 it was doing around 26mpg. Changing the ovc to the newest revision saw it rise to 32mpg which was great :)

How do you get it to go into FSI mode? I'm very curious to know
-
If you are doing lots of town journeys simply switch the engine off when you are sat at the traffic lights. You will see economy jump from 25 to 30 mpg immediately
There is no other way to improve economy around town. You cannot use fuel if the engine is off. I do this automatically now at every set of lights without fail

Light throttle, maintaining steady speed. Basically keeping it at 70mph without accelerating & decelerating. Nick @R-Tech pulled up the bit of the map that does this and explained how it works but tbh a lot of it went over my head :grin:

Absolutely :happy2:
The A3 has never dropped into the high twenties no matter how hard I try. I don't think I've ever seen it drop below 33mpg and that's including driving from my driveway into the street in a lot of cases which is measured in feet or meters :laugh:
600 or so miles to a tank in summer is nice and I noticed a marked difference in my fuel station appearances since getting the A3 :evilgrin:
A friend has just traded in his EP3 Civic Type R for a Rocco' 2.0 TDI 140hp who said the same. Finding I have this convo' with more and more people, too...
At the same time, I'm constantly looking at petrol cars online as a "what can I get for my second car at some point in the future" thing...
P.S. I need to pick your brains about a Milltek soon after our previous chats :happy2:
-
I guarantee I could get a 2.0TFSI A3 into low teens, lol. Unless the fuel computer in the A3 is more of a
bullsh*tter optimistic than the GTI.
-
Just a thought but could STOP START Technology be retro fitted to a Gti ?

I had a cursory look into this. I'm sure it can be done in terms of hardware, but it would probably need a new ECU and the cost would be massively prohibitive.
You could always use your right hand and turn the engine of manually. I'd imagine it would take some getting used to

The absolute lowest I ever saw out of my A3 was an average of 26mpg.... going around the 'Ring :grin:
Cat back non res and downpipe on my old one, definitely improved pick up and boost response and sounded pretty good for a diesel!
Chat soon Pete :happy2:

I love these threads, I'm getting 45mpg :signLOL: sat behind trucks on motorway.

My BWA never runs leaner than stoichiometric, unless you count the transient number a wideband shows when the over-run cut off kicks in. Pretty sure the 2.0 TFSI never runs in a lean-burn mode.

Really interesting posts here!

No...I havent checked this, this is making me think I should do now!
I think I have come up with a solution....
Buy a mk4 gt tdi 150 (or 130 but ecomony is the same in the book so might as well go for the 150) for about £2000, then I can use that for work all week driving round town that should be pretty decent especially after a remap :evilgrin: and then hopefully be able to still keep the gti for the weekends!

Go buy a 1 litre fiesta if you want economy :laugh:
