s4dreamer Posted December 9, 2002 Report Share Posted December 9, 2002 Just filled up and found that my car did under 29mpg on the last tankful - that's down from 32mpg, on the previous tankful, which was down from 35mpg on the one before that! I have not driven any differently, and the only obvious change is that the weather has got slightly colder. I've not added the Millers this time, just in case it is the cause. At this rate of consumption, I might as well be driving a petrol-engined car Link to comment Share on other sites More sharing options...
Chelsea Mick Posted December 9, 2002 Report Share Posted December 9, 2002 And I thought Diesels were not supposed to use so much fuel. My S3 is returning 26.7 mpg at the moment. And I don't hang around too much either. Link to comment Share on other sites More sharing options...
DeanS3 Posted December 9, 2002 Report Share Posted December 9, 2002 I'm averaging about 23mpg at the moment Link to comment Share on other sites More sharing options...
S3Bangs Posted December 9, 2002 Report Share Posted December 9, 2002 To be honest... I dont think I've checked, talk less know my fuel consumption... The joys of a fuel card.. .. Now wheres that Optimax garage for another top up! Link to comment Share on other sites More sharing options...
Chelsea Mick Posted December 9, 2002 Report Share Posted December 9, 2002 Blimey Dean I guess it must be that I do 30 mile round trip to work and most of it is nearly open road My average speed is just over 47 mph... Link to comment Share on other sites More sharing options...
DeanS3 Posted December 9, 2002 Report Share Posted December 9, 2002 My car rarely sees the motorway, its spends most its time on a and b roads and stuck in traffic. I get great economy when doing long journeys and stuff so i'm not unhappy Link to comment Share on other sites More sharing options...
fatcat Posted December 10, 2002 Report Share Posted December 10, 2002 Better get that checked Trev , I do about 70 miles each way in bumper to bumper traffic, I return about 45mpg, and my average speed is normally 25mph. On a good open run and driving sensibly (!) I return between 50-60mpg. Link to comment Share on other sites More sharing options...
s4dreamer Posted December 10, 2002 Author Report Share Posted December 10, 2002 I've got a couple of long runs to do today and tomorrow, so I'll see what it's like after them. If it still seems excessive, I'll get the dealer to look at it, although knowing them, it'll be after Xmas! Link to comment Share on other sites More sharing options...
Gaunty Posted December 10, 2002 Report Share Posted December 10, 2002 Trev, what is your normal journey length? I bet it's just down to the shops. Do a Mac type run up to Scotland and see what you get. Link to comment Share on other sites More sharing options...
s4dreamer Posted December 10, 2002 Author Report Share Posted December 10, 2002 Rich, my normal journeys are "down to the shops" - 2-3 miles a pop. However, that's what they've been like since I got the car, so that alone can't explain why the fuel consumption has got progressively worse. I'm off to The White House now for some beer and a mixed grill, so we'll see how it does today and tomorrow evening on those trips. Link to comment Share on other sites More sharing options...
Gaunty Posted December 10, 2002 Report Share Posted December 10, 2002 It'll probably be worse on the way back, with you a couple of stone of mixed grill heavier. Trev it's probably just cos of the bad weather we've been having, nowhere to give it a good blast to clean the soot out. Mine is running like a dog at the moment due to the cold. Very lumpy when it starts up but quietens down after a few miles. Link to comment Share on other sites More sharing options...
danksy Posted December 10, 2002 Report Share Posted December 10, 2002 I normally get 41mpg on long runs in the PD 150 Golf, but again I don't hang around! A similar driving style in the TTR returned about 23mpg (and 9points) Link to comment Share on other sites More sharing options...
worfke Posted December 11, 2002 Report Share Posted December 11, 2002 Releasing the handbrake while driving might help... seriously, you should get this checked, it is probably due to a faulty sensor causing the ECU to inject too much diesel. Have you noticed any performance degradations? By the way, is this average consumption displayed by the trip computer? Have you manually verified this number?

[/ QUOTE ] D'oh! </font><blockquote><font class="small">In reply to:</font><hr /> Have you noticed any performance degradations? [/ QUOTE ] The car was running a little rough on the last tankful - especially when just started. Other than that, the performance seemed pretty much the same. </font><blockquote><font class="small">In reply to:</font><hr /> By the way, is this average consumption displayed by the trip computer? [/ QUOTE ] No, I don't have the trip computer - the 28.6mpg was from when I filled up! I did 120 miles yesterday and the range shown on the DIS seemed to indicate that it was doing better, although it may still be short of its best. Will do another 120 miles today and then fill up to see how I've done. If it hasn't recovered to around 35mpg, the car will be off to the dealers for a check-up.

s4dreamer Posted December 12, 2002 Author Report Share Posted December 12, 2002 Okay, so I've done 270-odd miles in two days and it's taken just over half a tank. As I don't have the DIS computer, I can't see what mpg I've averaged, but this seems more like the 35+mpg I had been getting. Although, to be fair, I was getting that around town, and most of the 270 miles was motorway/fast A road. So, it looks like it might have been an abberation. Still keeping an eye on it though, but there doesn't seem any urgent need to visit the dealer. Link to comment Share on other sites More sharing options...
evojkp Posted December 20, 2002 Report Share Posted December 20, 2002 I've an A4 130tdi Quattro which has now done 6000 miles and I average 37mpg. This is with a mixture of A, B roads and motorway. Audi reckon I should be seeing 50 with a realistic 45mpg. Same old story when I question them is let it free itself off first. I've also been told to "rev' it hard for a couple of tankfulls...That should do the trick" ...John Link to comment Share on other sites More sharing options...

[/ QUOTE ] You must have something wrong with your car mate. I was returning 47 average round town this morning and then saw 53 average at nearly a tonne on the way to Hove this afternoon. Nothing above one litre in petrol form could compete with that. Link to comment Share on other sites More sharing options...
