mpg issues on ed30

[Hedge]

any idea why when you sit in stationarry traffic it instantly drops from early 20s to 17, its only on idle????

Yes but you are measuring miles per gallon and while stationary doing no miles.

[vRS Carl]

As Ian has said it will drop quite a bit when stood still Idling.

The car is measuring how many miles you are doing per gallon of fuel. If you are sat still your still burning off fuel but not going anywhere. So all the computer understands is "Fuel Burning Car not Moving" therefore you overall average will start to drop

Mine does it all the time.

I think the OP's mpg seems about right for a short journey.
I do around 50 miles per day, 25 miles to work and back. Since most of it is on the motorway I used to see around the 35mpg mark in my ED30, which i thought was impressive.

In my derv I'm now seeing around the 75-80mpg mark! lol. Driving casually as I did on my way to work and back in the ED30.
You do need to be doing longer journeys in a derv though - it takes much longer to get the oil to temperature etc then a petrol.
Nevertheless, a tank of fuel used to do me for a week in the ED30 - around 300 miles or so to a tank.
In the derv I get around 700-800 miles to a tank full - over 2 weeks worth or driving for me!

Im saving tons, but have no fun in driving! lol

Also on a short journey, you have the cat warm up process, where fuel gets injected twice per cycle, and the computer doesnt have so many data points to construct its average from so will be more heavily affected by the stationary phase of your driving, if all you do all week is your commute you would be better off resetting your number 2 computer and using this as your average commute consumption.

R32 figures are good, and I bet it sounds great through the tunnel! not been through blackwall since getting GTI but the dartford tunnel wasnt that impressive with the standard zorst.

Having recently bought the R32 listening to you TFSI boys go on about MPG does make me laugh.

I'm actually feeling a bit better - I thought the GTI was quite a bit better on economy that the R32 (and probably is on a longer motorway run) but looking at the figures being talked about here, for my commute to work I am no worse off in the R than I would be in an Ed30 

Out of interest, and slightly off topic - I though the average consumption figure on the DIS was stored until you manually reset it, but it appears to reset every time I use the car? Also, are the 'pages' of data (1 & 2) the same or does average MPG 1 differ to average MPG 2 in someway - hope that makes sense?

[mackit]

I thought MPG1 was the MPG for the last journey covered, i.e. from engine start to turn off, and MPG2 is the MPG since the last time it was reset, i.e. the average of all journeys since last reset.

[Richn83]

number one resets with engine turn off (if its greater than 2 hours) and 2 is only reset by the user or untill it reaches the end of its timing abilities either loops over on the mileage or hours driven.

I thought so - cheers.

I forgot to mention. After our trip out to the Pub the another night Ian. Both Myself and SparkyCraig left the pub, and both checked our Miles per Gallon from our 30 mile trip back, both doing same speeds, craig in the R32 and me in my Edition 30 following behind. We both clocked exactly the same mpg figure of 29.1mpg when we arrived back in Southampton!!.
Goes to show an R32 on the motorway is just as efficient as the 2.0tfsi.


DAM!!!!

Craig's is still too quiet though.

I do shift work and do the same journery at different times of the day. It's about 10 miles.

If I go to work around 8am, during rush hour, it takes me 40-45 mins and averages 22-25mpg.
If I go to work around 8pm, when it's dead, it takes me 20-30 mins ans averages 30-35mpg. 

[edd666999]

in my gti i do a 7mile trip to work and get about 32-36mpg...

[markc]

Pulled up at work this morning, M62 from Milnrow to Leeds, 41.6mpg 

[JPC]

have the finished all the central reservation work on the m62 yet? doing my head in! lol
