1.4 TSI fuel consumption

[SC03OTT]

What type of driving do you do?

My 1.4 Tsi DSG 122 bhp is averaging 32 mpg in terribly congested London traffic ....brilliant ! considering I was getting a little less from a Ford Focus 1.8 Tdci manual.

Well, recently my car now seems to be returning the sort of mpg I'd hoped for. My last two tank top ups i.e. to the brim, have returned ca. 44 mpg and this figure is also very close to the figure displayed by the MFD in memory 2 which I reset each time I refill the tank.
Some daytime journeys I am easily getting nearly 50mpg mainly on the quieter roads withoug a lot of violent acceleration etc.
I can't really believe this is due to my first service nearly two months ago. After all what would they have done to make the car improve its consumption like this? I am also being less fussy about fuel often putting in Esso regular petrol

i own a mk6 golf 1.4 tsi match 2011, has about 1500 on the clock. a full tank of about £65 will show about 350-380 mile range on the trip computer and i end up getting around that much aswell with normal local driving. other ppl are talking about getting 40+ mpg any one know why im not getting anywhere near this?

My previous car was a 1.4 TSI (122PS)Match with DSG and I used to get an average of 49 mpg (39 in town 52 open road) I have just changed and the new car is same but manual. On my first full tank fill up I have done 317 miles and the petrol gauge is one notch below half full ,computer says 220 to fillup. I expect to get 45 mpg out of this first tank fill and will report how things go as engine frees up.
safeer23 DO YOU HAVE A LEAD FOOT ? This engine will give best fuel consumption on using low revs , it likes to use its torque to cruise at only 1200 rev and at 1600 is asking you to change up. It all seems contrary to what we were used to, making the engine flog, but that is how the DSG box is set up to operate it and how it likes it.

I wonder how much fuel DRL's use?!

Not a lot.

A Golf sized car needs about 15 kW power (about 20 horse power) from the engine to maintain steady speed of 60 mph.
The two DRLs use 30 W.
Therefore the DRLs are adding about 0.2% to the engine's power (without accounting for losses in the alternator and electrical system).

To put it in to context, the car stereo is probably using nearly this much.

maybe theres something wrong with my car, cos its barely been thrashed and ive just used up my third full tank and this third one gave me exactly 370 miles, of which only 100 were motorway miles. what do u reckon?
