2.0 TDI sport low mpg

[GW]

I've almost completed 2000 miles in my 2.0spt tdi (17" wheels) and find it impossible to get more than 43mpg out of the car regardless of speed. My old 1.9 tdi would do 60mpg if you drove at fifty and were very gentle, following the traffic on the flat roads in lincolnshire.
I'm averaging 39mpg (true figure and exactly the same as the trip computer,very strange), My 1.9 was 47mpg. but no matter what speed/gear i cruise at the constant readout will never show more than 50mpg.

If i hammer the car (85-115mph) on the motorway it still does a true 37mpg, but if you drive soley round the my rural town taking it easy, i can average as low as 27mpg.
Can this be right? Or is there something wrong with the car?

 

[m0rk]

was your old car an altea too? or are you comparing apples with oragnes?

Just thinking that the altea isn't a slippery shape, probably weighs more than an older car & runs higher drag tyres

 

[redcupratdi]

about to say the same 38-43mpg is good for a the weight and aero dymaynics of the altea doesn't look the most bullet-like...imagine having a 2.0T 25mpg feel better now? don;t think 2.0tdi is as ecomincal as the 1.9tdi.

done many miles?

Well GW yours is the same as mine except I have the DSG 2.0 TDI, 17". When we discussed it last time in full, probably last year, the decision seemed to be that it you have 17" wheels then your MPG suffers. There have been posters with the 16" wheels and 2.0 TDI who got better figures than us 17 inchers.

I was hoping that as mine ran in to 10,000 or so it would improve, but no. Aircon takes extra power in the summer to keep the car cool so you don't see those summer improvements as you normally do. I'm not complaining except that the brochure ought to say with 17" wheels you won't get the published MPG figures.

My current figures from new are as follows based on brim to brim top up except where I've marked it it. Overal Ave is the overal average and average between fills is what it is, get's distorted when one does a part fill but the overal figures are as shown.

So 13,833 miles on the clock as meaured by the speedo with an overal average of 39.16 MPG. I don't drive like a vicar but then I don't drive like a F1 driver. It contains a bit of unrestricted Autobahr motoring on hols, but I've never taken it above 100.

As said the Pug diesel engines are more efficient. I bought this car for the looks which I bought my last diesel car for the engine and not the looks.

The 2.0 TDi lump doesn't seem to be quite as frugal as the 1.9. The Altea isn't the lightest of cars either, as has been said. The miles piling on can make it a bit more economical as well. Mine was awful up to 2000 miles, fuel wise.
Its a bit better now after 20k and has improved again slightly after the remap.
Funnily enough, the trip computer is more accurate post mapping.
All in all, for the accomodation and performance, I wouldn't swap for anything else!!

 

[Tell]

Thanks m0rk for addin the "code tags", putting boxes around it. I did think about graphing for seasonality and putting the graphics up as a JPEG, but decided that looking at the data there wasn't any seasonality. Most un-professional of me .

I wouldn't change the car as Loadswine says and one wants that science guy out of Fifth Gear to compute the mass of the car, wind restistance etc against economy for other cars with the 2.0 TDI with and without 17" wheels etc. I think it was pretty clear or it was at one point last year on this board that the friction generated by the 17" wheels dropped the MPG from the published figures. That is the beef that I think most people have with the Altea with MPG and the ones with this beef have the 17" wheels.

(sorry for anybody who's seen my MPG figures before )

 

[ALTEA DUDE]

Just returned from a 3 day 700 mile trip and got 49.2 MPG on the 2nd "total trip" trip computer so no complaints! I have a 2.0 TDi Sport

 

[Tell]

17" wheels, I think not ?.

 

[ALTEA DUDE]

Nope, standard wheels on mine, just as god intended. Only mod I've ever done was the speakers (with all your help).

I still have the factory fitted front wiper blades too, they just will not wear out - very impressive!

 

[Tell]

God and the Saturdays Daily Telegraph motoring pages. I must admit that 17" wheels make the ride interesting and that was after my comfy Citroen. So I went from a Fiat ride and handling to French then back to Italian so as to speak. Just as well the seats are good.

I'm still on the factory fitted wiper blades after 21 months which isn't bad and I haven't reversed them yet. I think I may have caught site of the availability of the Bosch aero twins in this country on a web site.

If it is the 17" wheels which is reducing the MPG from the published figures to what were getting with 17" wheels, then that is some friction.

 

[loadswine]

I wonder how much difference to economy the DSG box makes? Difficult to quantify I guess. Official figures show only slightly worse off. Not bad for super clever kit!

 

[Tell]

Yes I prefer to accept the relative difference between the published figures for manual against DSG and work on the basis that our 17" wheels have rebalanced these figures down. That seems to be the case since whether you have an automatic or a manual with 17" wheels reported MPG is sub 40MPG whilst those with 16" wheels are getting the published figures.

Any 16" DSG owners out there would like to confirm whether they are getting the published MPG figures or not. I don't think there are many 16" DSGs out there since people say DSG, yeah I'll have the 17" wheels as well.

 

[aceman]

I'm getting 44mpg around town and upto 50mpg on long motorway runs no matter what speed I seem to stick at. I am ruuning on standard 16" bye the way.

 

[FinerDetails]

My 2.0TDi sport is sat on 18inch tyres, 225 width.

Since the flywheel recall at 9k, it now has 12.5k on the clock, the car has averaged 48mpg.

The jouney into work today saw an average MPG on the OBC of 65mpg...

It has done some long journeys recently, and the average was dropped due to a progressive nature in order to get to and from the destinations...

 

[loadswine]

Some very good figures, I don't think I could get anything close to those no matter how I drove. Hardly ever take things sedately!!

Two theories on this one :

a. on 18" wheels you drive so slow to keep your fillings in which gives you the good MPG

b. it's the Bridgestone tyres that come with the 17" rims which offer a lot of friction, although Loadswine has changed his as I recall. I notice the Telegraph is keen on Michelin Pilot Primacy for comfort, noise and economy.

Yes, no I don't come close to these figures at all.

 

[FinerDetails]

lol:

a - some days I just cruise along and enjoy the drive, most of the time I use the torque, all 6 gears and everything the car can offer....

b- couldn't comment, mins on some never heard of brand lol

 

[loadswine]

My fronts are Godyear GSD3, but they are nearly done now , so will be putting on a set of 17" from the new Leon, that I picked up as a new complete set, and these are shod with the Bridgestones. I'll report if there is any change.

 

[Tell]

Loadswine, does that mean that you never had Bridgestone on yours when new.

My other theory on MPG for like for like cars was what type of oil was the garage putting in, since when I topped up with the extended service interval Audi / VW stuff my MPG improved. Last oil change at the garage it went down, standard Seat spec for the engine. I just topped up again with the extended service stuff Audi / VW stuff. I'm sure it also dropped after it's service at 10,000 miles when the factory filled oil was removed. That's my theory the long service stuff runs better and offers less resistance. Putting my neck out now I may get short down.

Some garages that do Audi cars only stock the long service interval oil and you get that when the services states the "regular" change, but you change as per normal. I first got it in Germany when a VW garage put it in, so I continued topping up with it on the basis of mixing good stuff with not so good stuff would get a better result.
