Gerry you really made me laugh hard because what you just said is effin true )

Well i guess that is how the car is

There must be some good roads in your country you can go and have an economic drive around there :p

 

You can do some good for the environment

I still agree with GerryCans first post.

This kind of consumption is not normal for a diesel even for short distances.

 

Unles you really drive only in stop-start traffic every day but then choosing a diesel for this kind of driving would have been a bad choice.

 

My wife drives our manual vRS 2x 10km a day for her commute (about 5k in the city) & the consumption has never fallen below mid-40s mpg.

When I take the car for work 2x 70km highway commute the consumption is over 50mpg (<5.5l/100km).

The DSG & 4x4 might reduce the consumption by ~10/15% but this is still nowhere near 24mpg.

 

You could get 24mpg in a petrol vRS driving the nuttz off it everywhere.

 

 

If you go to the highway & cruise at 100-120kph what is the average consumption you read in the maxidot?

 

Do you have any signs of regeneration (1000rpm idle, fan running when you stop the car)?

 

 

You wont see a 50% or even a 20% improvement in fuel economy when the engine has "run in".

At most you might get 1,2,3,4 mpg but mine has been the same since the beginning.

My VRS 4x4 - Well here are the real figures for my very fast return trip from Cornwall and a couple of commutes to work:

 

475 miles / 48 Litres to refuel = 9.89mpl

9.89mpl x 4.54609 litres = 44.9873mpg

So just a nats knacker off of 45mpg - real time mpg.  With 1800 miles on the clock.

 

That's pretty damn good considering the MFD is reading 51mpg average; we all know they read higher than the real world.  I'll post my next refuel figures, as these should improve, as it will be a more sedate drive, as I'll only be commuting for the next week.

Gabbo,  well my first 200km drive on the highway had a 6.2 consumption at 130km/h max... But when cold and in the city.. my drive to work is 3-4km ( I know lazy but I enjoy the car ), I get when I get to work 12.5 - 13.4l consumption.. the thing is that I went to Skoda and they said after putting the car on a computer and checked the fuel tank, that everything is fine and ok... so what more can I do... and yes most of the time I get the 1000 RPM regeneration and sometimes it smells like burned rubber and the fan works like crazy.. The weird thing is that even on those 200km on highway with 6.2 consumption... afet 380km I was near half of tank empty... What more can I do if the service says the car is ok... ? :( Also the weird thing is that I've and 7l consumption on a longer urban drive ( 12km )... It is very weird.. I have since last refuel avg of 11l... only urban

Edited 15 March, 201610 yr by aobretin

And another weird thing is that i get 7l consumption on an urban drive 20km in since start and 10.8l in a same condition urban drive but 60km.. I mean why.. And 11l after 60km trough the city seems pretty steep

Are you measuring your fuel economy from the maxidot on your short trips (3-4, 12, or 20km) or are you looking at the fuel economy tank to tank?

i.e. Consumption since last start over a distance of 4km vs consumption in 400miles of mixed driving ?

 

For sure when the engine is cold, the fuel economy will be much higher & you need to drive longer to average out the "real" working economy from a engine which is up to temperature.

You wont get close to 5L/100km until the engine oïl is at operating temperature.

 

 

6.2L/100km sound OK on the highway depending on how you were driving & the traffic conditions.

The fuel economy really reduces above 100km

 

If you are only driving your car 4km each day in the city (and never driving it regularly for longer distances) then I guess your consumption could be correct.

Especially if the car is trying to regenerate all the time, this can cause a large increase in fuel consumption which could explain your problem.

The ECU will inject extra fuel into the exhaust to increase the températures in the DPF to start the regeneration.

Then almost straight away you stop...

To be honest I think there are too many unknown variables in your 'urban' driving to even comment accurately on whether the consumption you are achieving is good or bad.

Highway driving reduces the variables and gives a better idea of what is actually happening. I agree with Gabbo that 6.2L/100 at your stated 130kph is pretty darn good.

 

It would help if you could give us some idea of what you were getting in similar motoring with other cars you have owned and what they were.

 

I have seen published reviews from motoring journalists that got worse consumption than yours during their testing of comparable diesels in highly congested peak hour Sydney traffic. Of course it is not their car and they hardly drive for economy but still if you don't get much above 2nd gear and always accelerating and braking to a stop then your actual results might be regarded as pretty good.

@Gabbo, you are right.. somenone from skoda explained the DPF thing to me exactly like you said.. this and the new engine results in pretty much higher consumption.. recomandation - at least once a month a long drive till the regeneration is ok.

But when cold and in the city.. my drive to work is 3-4km ( I know lazy but I enjoy the car ), I get when I get to work 12.5 - 13.4l consumption.. 

 

I got similar figures (8.3km/L or 24mpg) from my 1.6TDI DSG with similar usage pattern - cold (around -10 every day), short trips to office (7km one way) plus Webasto usage every time. This figure is from tank-to-tank calculations. Covered 334km on a full tank before the low fuel warning came on. MID showed 13.7km/L or 39mpg. I too noticed many regens during that time.

 

During the last refill, the consumption figure was 11.6km/L or 33mpg while MID showed 15.2km/L or 43mpg. Usage pattern was similar, except that it wasn't as cold (still around 0 on most days) and the Webasto wasn't used as much.

Manlms.. so you have a big consumption for a 1.6.. well i guess this DPF regen is screwing us good )

I hope you don't mind me asking but while I know what the Webasto does, exactly how does it do it? Is it a plug into the electric mains thing or does it use the diesel fuel to pre-heat the vehicle? If the latter then would that account for the disparity between MFD and actual consumption?

Websato uses diesel to pre-heat the vehicle. The specifications say that it uses 0.2L fuel for 20mins of heating. Even taking that into account, there is still a gap between the MFD and actual consumption. I guess it's safe to say that MFD over-estimates the fuel economy and Websato under-estimates the fuel usage.

 

Maybe the MFD does not take into account the DPF regeneration either?

Thanks for the explanation, I cannot imagine the MFD would cater for Webasto fuel usage which would account for some of the difference

Generally UK diesel Octavia users report their MFD as pretty accurate unless they have a DTUK tuning box fitted for extra performance and that does throw the readings out.

 

For what it is worth my petrol MFD is pretty well spot on accurate against Fuelly recorded consumption

Guys I have one quick question.. why when I'm stationary with the engine on and on parking for a longer time my since start consumption slowly climbs to even 29l in half an hour even though my instant consumption is 0.7l which is normal.. I'm curious from a tachnichal pow

Hi I plan to buy diesel 150hp (not sure if DSG yet). Driving distance in regular working day 15/16km (need to leave child @ school,etc that's why I need each day the car).

I am ready for the DPF regeneration, usually we travel outside the city eaxh weekend or twice a month. 15-16k km/year...

What shall be the proper driving to preserve the DPF and operate it normally? Shall I expect close to your figures,as this lower powered machine?

I choose diesel due to lower buying cost in my country in the beginning. I prefer the 1.8 TSI but will cost me more money..

Edited 24 March, 201610 yr by fallenfbsd

Bigiainw, was that urban consumption ? I can t get mine to go mpre than 30mpg... urban i mean

No, it was about 50/50 urban and motorway. Second tank gave 44.6mpg, averaging out to 42.6mpg over both. Definitely loosening off after 1000 miles

I have 150PS DSG Estate, and I have had a 150PS DSG Hatch as well. Both average about 49mpg (UK).

 

A manual will probably get you 5mpg more.

 

Don't worry about the DPF, it will sort itself out.

I am less worried about the DPF these days, as andyvee says jus let it do it's thing and if you do get the DPF warning lights (or glow plug/engine management lights) refer to the instructions in the owners manual. 

Thanks Davitc && Andyvee
