Does anyone own a Polo Dune 1.4TDI

[pattop]

I recently bought a brand new (56) Polo Dune TDI version with the 1.4 engine (as it is the only available verison in the UK), I found the fuel consumpltion is far less than the spec. Example, motorway (M1): 45.6mpg(imperial), city: 43.8mpg, country A road 51-57mpg. But the spec mentioned something like 47.8, 57.6 and 65.8mpg. Anyone got any idea??

How many miles has it done ?
Probably not run-in yet.....

[pattop]

It has done 8,500 miles already!

[Lex Luthor]

I would wait till at least 10K if not longer.
Do not baby it too much or there can be problems.
Are those mpg figures from the onboard computer ?
If so you need to do a brim to brim measurement.

[pattop]

Why wait til 10k? Isn't 8.5k enough? Honestly, the fuel consumption hasn't change much since I had it on 10miles. Originally I thought it was just the on-board computer is being inaccurate, but after filling my tank up, it does seem matching the computer figures. What did you mean by baby it anyway?

Hi, my son has an 05 reg Dune with that engine. He's had it from new. I'll get him to do some measurements, but he does not hang around! Can't say he'll be looking for economy!
That aside, have you tried to get a real spare tyre? We had enormous problems. Because of the mileages he does, he did not want to be left in the lurch with a can of tyre weld! In short he got a superb replica bbs rim from a supplier in Ireland. Check out the cost of the genuine rims. Sit down when you get the price!
My son also had problems with the radio. When it got hot, the lcd display faded so you could not read the button functions. In the end the dealer fitted a Blaupunkt unit with a removable facia as the two replacement units both did the same. Check yours before the warranty runs out!

Hi, I own a 2004 Dune TDI with 30000 on the clock and am getting about the same mileage as you, which is about 430 miles per tank of diesel. Previously I owned Polo SDI 2003 which I drove to max rev all the time and was getting 500 miles plus to the tank. VW assured me that the TDI is more economical. I have tried driving it hard and very softly but still can not get the mpg as quoted by VW.But what a great little big car.

Hi there. I have recently bought a polo, not a dune, just a regular one and I am having similar issues. Did you get anything resolved with your car?
Again, I was expecting at least 500-600 miles per tank and only get 400 ish!

so you guys found out why its not doing 500+ miles per tnak?

If this sounds insulting I assure you it's not supposed to!

Look at the way you use your right foot on the gas peddle.

It's not the quantity of engine revs that drink the fuel, but how far down you have your gas peddle.

So you may have your foot resting very lightly on the peddle with the revs quite high. If you change gear hence lower revs but peddle pushed further down, then you will get worse fuel consumption.

I know it sounds like I am having a dig, but I am not. I do alot of test drives with customers and often they change gear inappropiately.

I get 33 mpg as an average from a 2.5TD Toyota Hilux twin cab, and recently 60 mpg from an A6 1.9 TDi Avant.

Now allow for the fact that the test driver for VW will be better than me and you will have the official figures.

Happy motoring

hope that wasnt aiming at me.

but anyway, i am on about a normal driving with normal driving. it is obvious the harder you press down on your right foot, the more fuel it consumes. :biglaugh:

I've found that no car I have ever had has matched manufacturers fuel economy figures.
Reading some articles in the motoring press this is apparently down to the way that the figures are obtained. Manufactures put an engine on a bench in a workshop hooked up to a computer and test them in perfect conditions.

You and I actually drive the cars on a road. There are therefore 101 ways in which we will never match the figures.
Road surface variations, inclines, headwinds, stopping and starting again, load carried, slightly off tyre pressures in the car etc etc etc.

If you look at the manufacturers fuel consumption figures for motor cycles you would believe that the average car these days is more efficicent with its fuel than the average 600cc motorcycle. This is because motorbikes are tested more realistically to obtain the fuel economy figures.

However economically you try to drive your car I suspect you will never match the quoted figures, and I believe the manufactures figures to be a bit misleading. I don't rely on them and it is probably best just to use them as an indicator of how fuel efficient one car can be when compared to another.

Finally how do you rate the Dune in other aspects as I fancy one when I come to change my car

You are correct, it wasn't aimed at anybody.

It is quite amazing how many people change up through the gear box too early and labour the engine, hence use more fuel.

They seem to believe that the quicker they get into top gear, the less fuel they use:D

Ohhh well keeps those poor fuel companies going:biglaugh:

Hi, have any Dune owners experienced tyre failure because of splitting of the tyres on the inner walls only? I see that VOSA has done a recall on Pirelli 18" 40 profile tyres failing because of tyre walls splitting when fitted to Alfa Romeo's. I am just wondering if this also affects the 17" 40 profiles they produced. My son's car has just had two consecutive MOT failures on Pirelli tyres made in 2007.

Hi,I have a 56 plate 1.4 TDI Dune,my wife drives it,but we are fed up with the harsh ride from the 40 profile tyres.Would fitting a higher profile tyre,like 50 say,make the ride better,and would it affect the MPG ??? :1zhelp: :confused:
