mpg

I've never got more than 50MPG out of my 1.4 TDI75 and that was went the back seats where removed and the skinny tyres where on.
Now the seats are back in and the 215 tyres are on I'm lucky to get 42+MPG round town. :):(
 
Will a new air filter (KN) improve anything mpg wise? Former user of the car told me it was getting just over 50 now when I have it, its now on 45, this is since I reset a month or so ago.
 
My fuel consumption has risen with the recent cold weather and spending 2 hours travelling 5 miles last Thursday morning:mad:......last tank gave only 52mpg.....at least i refilled at 99.9p litre:D
 
Hmm, the cold weather really seems to affect these cars, doesn't it? After a good service in the summer my 1.4 Tdi (75 bhp) was doing about 60-63 mpg on average. Now the winter is here that's dropped to 53-55 mpg. I was so annoyed I took it into Audi for a full diagnostic (the warm-up time was slow too and suspected a duff sensor somewhere), the car came back with a whole page detailing what they had done and checked and the car got a clean bill of health. So I'm not happy. Now the fuel price has dropped I'm less bothered though - diesel for under £1 a litre woo hoo!
 
Hi Richard and Blue Two
First, A K&N filter will be capable of flowing more air than the standard paper element version but will make no difference to economy or performance unless the engine actually needs the extra air. On our A2's it may give a slight advantage if the car is tuned for over 110 bhp but the only way to confirm this is with a 'before and after' dyno test. (I'm assuming correct servicing here and not comparing dirty with clean elements)

Winter fuel consumption has been covered before and a 10% drop in mpg is fairly normal - on any diesel car. This can be attributed to the use of 'winter' diesel which is in the pumps from around Nov to March. Its used to prevent waxing in the colder weather but the different fuel properties have a negative effect on mpg. Secondly, all the mechanical components (gearbox, diff, wheel bearings etc) take longer to warm up which increases drag. Finally, in wet weather the tyres have to move thousands of liters of surface water and this absorbs a lot of extra energy. There are many other factors like the aerodynamic drag, increased use of electrics etc which i'm sure will also be worse in cold and dark weather conditions.

Now we ( apparantly...) have global warming i didn't realise the suppliers still blended diesel differently for winter use, i assumed that was only for really cold countries. Just imagine how cold it would be without Global warming.....;)I am used to and aware fuel economy suffers in winter for all sorts of reasons, it is just more noticable on the A2 than any other vehicles I have had, my A6 TDi only increased by 2mpg at the most and some cars have barely registered any difference.
 
I have a 1.6 FSI, and I can not get more than 260 miles from a full tank! :(

...is this normal for this type of car???

Cheers
 
If the car has the 34 litre tank I think that works out at about 35mpg, which isnt too bad for short commuting trips in the city. If the car has the bigger tank (I dont know if this was available on the 1.6) its down to 27 or so which is poor unless you do low miles and very short trips where the car has no chance to warm up? Whats your driving style and how many litres to fill your wee treasure?;)
 
I have the 42 litre tank, initally I thought it was because I had only just gotten that car and was a bit over zealous with testing what he could do. Anyhow, I drive to work which is just under 9 miles each way and the engine is always fully warm after about 10 mins (takes me around 30-45 mins). I haven't had a chance to really try out a longer journey and am only doing around town at the moment.

The car was suppost to be fully serviced when I bought the car from an Audi dealer in November, but also noticed that the car is stating it needs a service in 5000miles. :confused:
 
I've just changed from the TDi to the 1.6FSI. The diesel had the smaller tank and the petrol has the larger one; at the moment am getting about the same miles out of a tank-full with the FSI (about 270 when it 'buzzes', which is then around 35 litres of fuel to fill back up again)

I never got economy that was startling out of the diesel, though it's a good little engine. On my daily commute (15 miles of mixed town and a-roads) i averaged around 45mpg though on a rare long run that went up a fair bit. Now with the 1.6 petrol it's about 35mpg but assume could get 45mpg out of longer motorway runs etc.

Using super-unleaded it will be more to run the FSI but the engine is a lot more refined and quite different in its characteristics to the diesel.
 
My1.6FSI does about 10miles per litre, or about 45mpg.
Short runs kill the economy though, have had it as low as 35mpg. I think its because the engine takes about 4 miles/10mins to come up to temperature.
 
My 1.6FSi has averaged just over 50 mpg over 59 000 miles. As it says in the handbook, for max economy keep in the 1500-2000rpm range (except when in 5th gear) and use a light throttle. V-Power fuel used. Air con off (a/c not present on mine) and 2.3bar tyre pressures help. Keep off the brakes - they only slow you down.
The stratified charge system is only in operation at light throttle and low - mid engine speed.
Seems a bit slow at first, but you get used to trying to carry your speed through the bends.

Very impressive - almost unbelievable for a 1600 petrol, therefore I admire your frugality and careful driving. Given that its winter, we are averaging 42 with Ada, mind you I have mucho fun every time I drive her! Its just too much fun to drive by the textbook!!! :D;)
 
Agree with you there, the 1.6FSI is like the 205GTI that I never had! It loves to have a bit of an Italian Tune Up every once in a while!

Makes my 2.0 Volvo V40 appear VERY sluggish in comparison.
 
Over the last 4 months of ownership of my 1.4tdi 75. I have been monitoring my mpg and on typical tanks consisting of the odd long motorway run and mostly driving to work and back I have been getting between 55 and 59 MPG. these are calculated values from brim to brim measurements and not from DIS as my car doesnt have it. It has noticeably dropped in the cold snap which must be in part due to the webasto heater burning diesel.

No matter what i did i was unable to get over the 60 MPG mark.

Anyway this weekend I visited friends in Brighton which from derby is just over 200 miles each way. I brimmed the car and i did 407 miles before the light came on, it was all motorway there and back i must admit i did drive just under 70 all the way, I was trying to see what i could get.

Anyway it took 27.42 litres to fill it back up which by my calculations is 67.5MPG. I was quite taken aback as it seems on a long careful run more than 60MPG can be achieved. I have the 34 litre tank and i filled up when the light came on so theres is still a lot more range out of the tank to be had, just depends how much i push it lol.

I got a similar return on a decent long m-way run in the summer - constant speed motoring is when small diesel engine, and a very low drag coefficient really come into play.

I only just got 40mpg out of the last full tank though - again another whole 30ish litres entirely in London traffic and I've recently re-developed my old "drive it like you've stolen it" driving habit - been so horribly stressed of late and you tend to take it out on the right foot in those situations, whoops. Anyway, still satisfied with that. Did 300miles at the weekend on m-ways though so that should restore my mpg somewhat.

I didn't realise Brighton was connected to the motorway network ;-)

Still, excellent mpg. Shows it can be done with a 1.4.

I must try harder as my mpg has dropped below the magical 60 mpg. Either that or buy one of those 1.2s with the funny gearbox ;-)
