Make the GTI drink less?

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?



 

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  

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  

Absolutely  

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  

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  
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

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 

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

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

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  

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!

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 :)

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  and then hopefully be able to still keep the gti for the weekends!

Go buy a 1 litre fiesta if you want economy
