Can other owners let me know what sort of mileage they get from a full tank. I'm struggling to get over 400mile before having to fill up again. I've ran it till it shows 5 miles left in the tank and I'm only just over 400.

My stop start has only ever kicked in twice in the 6 months I've had the car. I've tried various different things like air con off/on. Heater cold medium and hot and still nothing. ( it does work when I stall it though) I've phoned and booked it in but would just like opinions on here. Could it just be my heavy right foot?

Hi Dave c30,

As regards fuel consumption on A3 2ltr TD i I have no trouble reaching 700--800 km before refuelling.This is my 2nd A3 and these figures relate to my last car, however on picking up new vehicle 2 weeks ago the dealer had left half a tank of diesel and I was almost at 370km before I refuelled , this without any warning light.

Have always found the car to be very frugal on fuel , even with city driving, amazing on motorway journeys. Let me know how you get on at dealers.

Regards,

Eric.
 
Thanks for the reply Eric,

I'm hoping it's not just my heavy foot but I recon I'm about 100 miles down on what it should be. Suppose I'll find out on Friday.
 
My 150PS TDI 8V regularly gets over 500

For reference, I would often get 600 from a tank in the 140PS TDI 8P, but it had a bigger tank...

Sounds like you have the same engine. I hope they find the issue.
 
Fwiw,
I had the new shape Seat Leon with the 150 engine. I averaged between 43 and 47mpg in the 8 months I owned it.

There's definitely something wrong here.

My stop start can sometimes kick in 10 times on 20 min journey even with lights and heater on.
 
My 3 month old 184 quattro is giving me around 40mpg avg, mainly 45 minute journeys motorway driving (although not always at motorway speeds). Best I've seen on the DIS is 54mpg avg with little traffic and driving with a very very light foot at around 60mph.

I've tried the climate on "eco", heated mirrors to off position etc. to see if it would make much of a difference....I don't think it does.

I'd say I'm definitely around 6mpg down on average compared to my 2009 140 TDI where I'd regularly get into the 60's with a light foot, but I do have more power and quattro, so I guess you can't have everything.
 
I've just checked the DIS mpg reading on my 2.0 TDI-184 s-tronic quattro. I have not zeroed the long term reading since it was new in April 2014 and have now done 20k miles and the reading is 44.5 mpg. Slightly less the my previous 170 (46-48) but if I was concerned about the mpg I would not have purchased a 184 quattro.

S-Line 2.0 TDi 150 engine and average around 450 to a tank - although only down to the last white dash, never in to the red zone.
Also, I don't have the most fuel-efficient roof.

Therefore, there's definitely an issue with your vehicle - even if it turns out to be your right foot !!

I tend to tootle around around 60mph for most of my journeys - 70 / 80 for overtaking, etc.
 
I get about 450 per tank 60/40 urban/motorway funnily enough I took a photo of the dis showing 57.8mpg after 57.8 miles thought it was a bit od a coincidence. Stop start works all the tie with 6 minutes of starting up and that on a 184ps I'd get yours checked mate
 
I've had my 150 saloon for 18 months. Covered 68k miles and not yet reset dis. It reads 48mpg ave over that time. Currently running 235/35 19 Winter tyres which is costing me about 3mpg. Not sure on total miles to the tank but what I am sure about is that driving style has a massive effect on mpg dis readings. Drive like a granny keeping revs low and it's up in the mid to high 50s. Drive like it's a hire car and low 40s are the norm.
 
The worrying thing is S/S not kicking in at all. Like others have said mine kicks in all the time once the car is slightly warmed up (not even fully).

On occasion it doesn't but usually because of AC.

Hope they find the issue...and it sounds like there is definitely an issue.

Once up to temp it should kick in as already said. Let us know how you get on.
 
So it seems like I may have a problem. It's getting picked up from my work tomorrow so I'll update tomorrow night.

Thanks for the input everyone.
 
So it turns out I should read up on these things before booking the car in:grimacing: turns out if the windscreen heater button is on it deactivates the stop start apparently. I always drive with the blowers on the windscreen and have stop start work on other cars?! Oh well, free wash, Hoover and health check:tearsofjoy:

And I have a heavy foot

I also drive with my windscreen heater on - but there are two buttons to do that. One button you press and all hell breaks loose - AC, full fan etc. The other one just routes some air to the windscreen.

I have the latter button selected all the time and my S/S is fine. I'd recommend that one if you also have problems with the windscreen steaming up (like I do).

I have the 184 ps engine and get on average 36 mpg around town and if I drive very carefully 55mpg on a long run.

By the book it should be doing around 65mpg to the gallon on a long run...............I'm concerned by this thread and the what looks like to be poor MPG figures from the 2.0 TDI's.

I am taking delivery of a 184 Sline saloon next month as a new company car and will be gutted if these are the figures that people are achieving.

My current B*W 320 M Sport is getting 56 mpg around town and 65+ on motorway journeys when cruising at 70 - 80mph.

If I end up getting 36 mpg around town then i'll be back into Audi asking some serious questions as these sort of figures are miles and miles off what Audi claim :-(

With regards to your stop/start not working:

The Engine will not switch off if any of the following happens

  • The Engine is still cold
  • A/C is still trying to reach the selected temperature
  • Exterior Temp is Very High or Low
  • Windscreen defrost is on
  • Battery is low.
Having the AC on will also reduce fuel consumption, but not by a massive amount!

If you expect to get anything like the figures given in the technical data section of the Price and Specification Guide then you are living in Cloud Cuckoo Land. Those figures are EU lab test results for comparison figures and no one will ever achieve them.

My dealer always says that to get some idea of the overall fuel consumption to expect, take the given Fuel Consumption - Combined figure given in the data, subtract 20% and you won't be far wrong. For my own 2.0TDI-184 s-tronic quattro Sportback the figure given is 57.6. Subtract 20% and you get 46.08 which is very close to the overall average of 45.4mpg for the 25k miles since my car was new.

Just been out and checked the DIS again and that's correct 36 mpg. The car has 15,000 miles on it and does very short trips around town.
I'm going to fill it up over the weekend and will do a proper check.
 
I've just returned a TDI 150 with 41000 on the clock and my overall average was 53mpg. That's with not a particularly economical commute route - some single track roads and lots of 3rd & 4th gear. On a run on A roads I could easily get it into the high 50's or even the 60's. On a motorway if I kept it around about 80 it would easily be in the mid 50's.

You need to give the engine 1000 miles or so to loosen up before you'll see the best figures.

I've now got a TDI 184 so will be interesting to see the difference but only have a few hundred miles on it at the moment.

Well for your information I am not living in cloud cuckoo land, the last 4 BMW's I have had have either matched the book claims or in the case of the 320D Efficient Dynamics it actually bettered the book claims once it got past the 70K mark where on some journeys from my home to Portsmouth (220 miles) it averaged 74mpg at at average speed of 69mph.

If my new A3 184 Sline returns only mid 40's to the gallon at motorway speeds then I am going to be severely hacked off by this and I find that claims in the book that are 20%+ out is classed as miss-selling products.

I was looking forwards to getting this A3 now I'm not so sure :-(

I wouldn't worry too much, Its all about the way you drive. If you're consistently getting that kind of fuel consumption out of your bmw's says that you're light footed and read the road ahead so should get similar results in your new Audi.

After 13000 miles with my 184 FWD I have seen, from calculations from tank to tank, 49-58mpg. Ranging from my 13 mile commute along A/B roads to 500mile round trips to Cornwall. Stuck in slow moving traffic on the way to work I have seen the DIS as high as 68mpg, so the numbers are achievable
 
The only thing I'd say is if you are comparing an Efficient Dynamic 320d to a S-line 184 A3 you are comparing chalk and cheese. The ED BMW is a car set up in all ways to be totally frugal. The S-line isn't. Yes, it'll be good on mpg but it won't get near the ED BM. Comparing my time in BMs to Audi, I'd say my Audi is much more frugal around town but worse on motorway runs.
 
I started a similar thread a few weeks ago, having bought a 2013 2.0 TDI s line. I was a bit worried it isn't as good on fuel as my previous 2.0 pd TDI.

Couple of tanks later and seems I am driving the car more suitably, getting 460 miles to the tank before the light comes on, approx 46mpg. Myself and wife drive with a quite heavy right foot. I thinks that's got a lot to do with it, and can have the DIS showing over 50mpg.

Looking into a revo remap as missing the power the old A3 had.

I'm also finding of a Revo remap. Let me know how you get on
 
See you are from Harrogate, I'm in Devon and made the trip in the new year to pick up my A3, was a private sale so worth the trip, but know it's too far to travel for a remap.
I say this because I have spoken to a friend of mine who is a VW specialist and Revo agent. Spoke to him in Friday, 150 model will bring it to 190 with a large increase in torque, still won't have punch of the PD but will be a big improvement.

Even when I compare the figures of the A3 Sline to my old 14 plate 320 M Sport which could do 65 mpg with ease I am slightly worried. It appears to me that what BMW are claiming in the book their cars will actually get near to them figures where as the Audi's seem way off.

Only 3 - 4 weeks to go before I get the A3 so time will tell I suppose..............
 
Speaking of AC actually - mine is always off. I think (maybe wrongly) that it has a significant effect of power and MPG? Anyone know how true this is of today's A3s?

Will do a search of this forum as I'm sure it's been asked a thousand times.

Mine is a company car but for personal and work use. Still have to pay for fuel for personal use though - though it's not really a concern since that's the only cost for the car (other than the fixed monthly payment for the car itself but that's all pre-tax blah blah).

I can drive like a maniac - if the brakes go or the tyres worn they replace them for free. Zero excess if I ding it as well. Bad combination...

I actually pay for my fuel then claim the business miles back off the company at £0.13 per mile so hence to why I was concerned at the poor MPG figures as if I am not careful the car could start costing me out of my own pocket to do the business miles if that makes sense??
 
2.0 150 tdi man 'box - 470 miles covered / 55 miles range remaining in tank calculated as 51.0 mpg on fuelly app I use (I never go by DIS readout). Battering into a headwind & rain mostly last week (on motorway 95% of the time) so reasonably happy with that as my first tankful considering wipers, a/c, lights, heater etc etc on nearly all of that time. & I'm sure it will improve as I get more familiar with the car.

That does make sense. My business miles at £0.14 per mile and that just about covers the fuel cost on most journeys...but I do have to drive carefully to keep within that.

Good grief..............the 184 TDI is 28% out from the book claims, how can Audi get away with this as there is 20 miles difference in mpg in terms of claimed vs actual???
Click to expand...
Simple. Just carry out the standard EU lab tests that all manufacturers have to do to the same set of rules. Everyone accepts that these bare no resemblance to normal day-to-day driving but can be useful to compare one model with another but that's about all..
