Skoda Octavia 2.0 DSG TDI Fuel Economy

[Johnny_dust]

I have a question regarding fuel economy. I have a 07 build 2.0 TDI Octavia Sedan with the DSG box. I don't think I am getting very good fuel economy or at least as good as I expected. I drove from Melbourne to Canberra today and it averaged 6.1 and that was with some economical driving and no air-con running, earlier in the trip it was sitting on 6.4. I really was expecting it to be around 5.5 on the highway and was hoping to get around 1000kms out of the tank. The car has 35000kms on it with a long term average of 6.5.

Any feedback on what sort of fuel economy your getting would be appreciated as I think mine is using too much fuel.

Thanks in advance

It might be worth having a look in the Mk V and Diesel sub forums here for more examples of real world economy. Yours does sound like it might a bit thirstier than average.

Maybe if you can give us some more info about your load, tyre size & pressures, cruising speed, driving style, roof racks/top boxes etc we can comment more usefully.

The economy calculated by the trip computer can sometimes be inaccurate (usually a bit optimistic). The best way to get accurate fuel consumption figures is to use the fill to fill (or brim to brim) method, recording distance and actual fuel put in, prfereably over at least 2 or 3 fills.

Note also that the long term average and totals in the trip computer [memory (2) ] is reset every 99.9 hours of driving.

My 2.0 TFSI gets more like 9-11 l/100km, but it is a petrol and I do lots of short trips and tend to drive a bit enthusiastically (when you do less than 7,500km a year in a car fuel costs aren't usually much of a worry).

Seem high for hwy driving but as mentioned need more info.
What speed were you doing aircon on , how many people ect.
Have you calculated your fuel consumption manually to see
accurate the MFD is.

My Jetta at 110 on constant flat Hwy I would expect mid 4's

added ....Just done a return trip from CC to nelsons bay, 3hours
driving consisting of 110km/h on Fwy for 80 mins and averaged 4.6
Might be worth using BP for some time and some injector cleaner if you don't use BP,

My RS TDI DSG Wagon averaged bewteen 5.6l/100km & 5.9l/100km driving bewteen Melbourne to Mildura and back the 3 times I've done this trip - approx 550km one way. Driving conditions OK each time, although once it was windy.

The average speed for the trips was between 106km/h & 109km/h - mind you the speedo is out between 3-4 km/h, so true average speed in less.

Each time the car just has myself and approx 50kg luggage in it. The car currently has 7,300km on the clock.

Driving on the freeways around Melbourne I've had the average fuel consumption down to 4.8l/100km but the average speed was much lower.

So to compare this to your car we need to know the load you were carrying, twoing or with roof racks on, the average speed (the faster you go the more fuel used) and was it raining heavily or windy? All these can increase fuel consumption.

Cheers

Your fuel consumption will improve even more when you get more K's on the clock.
I noticed a difference when I reached 18000k's

[dazag]

what tyre pressures are people running in their tyres??. Also heard the MFD can be out slightly, if you need to do the full tank to full tank checks and work it out manually, I think on the briskoda forum there is a post that tells you how you can go in and adjust your MFD so the L/100km is more accurate.

Thanks for that. Cheers

Thanks for all the info and sorry for late reply, I'll provide some more trip info for you guys as I have return trip details too.

I travelled Melbourne to Canberra - Avg 6.1

Canberra to Melbourne - Avg 6.0

I had my wife in the car with me and overnight bags and a set of golf clubs in the boot. I have skoda 17" factory alloys with pirelli rosso tyres which were inflated to 36 all round for both trips. On the trip down I used Mobil and on the trip back I filled up with BP.

Fuel economy improved whenever I went through any towns and slowed to 60 and then went the opposite way when I got up to cruising speed on the highway. I was travelling at approx 110 (according to GPS) the majority of the way. I used cruise control the majority of the way. No air con running, just fan on economy mode.

When I was in Canberra midway in the trip and I tried to start the car one morning from cold, without pushing the accellerator it started and stopped about 4 times before i really had to give it a pump to get the engine going, never had that problem before though.


Also, on another note when flicking through the trip computer, from time to time it stalled (didnt change to next reading) or a different thing came up to what should have come up in that spot if that makes sense (eg kms travelled instead of litres uses per 100) but then after a few more clicks it corrected itself and worked fine again. Anyone else had a similar problem?

And, last but least, one of my rear parking sensors got pushed in a bit and now beeps rapidly whenever I put it in reverse and Im damned if I can work out how to get it back out again as there is no way that I can see to reach in behind the bumper and push it back out, hopefully I can get it fixed under warranty.


All feedback and assistance is greatly appreciated.

Definitely something not right especially if you were traveling at only 110km/h.
I think the first thing you need to do is manually check your fuel consumption.
And by doing this you will know how accurate your MFD is.

Do you know how many k's your getting out of a tank of fuel, especially when
you were on the HWY.

i have the 1.8TSI 6m.

Fuel exonomy noticeably improved at the 5000km mark (for no particular reason) and impoved again after the 15,000km service (Castrol Edge Sport 5w-30)

The MFD(2) reading is currently 6.2L/100km - which is 6.4L/100km actual.

I'd be concerned if my diesel was only getting similar economy.

edit: running 36F/34R in (narrower than RS) CSC2

[wombatoutofhell]

I have a 07 build RS with the TFSI engine and 6 speed manual. I drove from Cranbourne in the outer south east of Melbourne to Canberra in March on a tank of fuel-although it was running on fumes when I filled up. I think that was about 7.1 l/100km. Cruise control and climate control were both on. There was a fair but of stop/start driving due to roadworks, but alot of 80km zones as well which would have helped a bit. The trip home was similar economy.

Under similar conditions, our 1.9 TDI DSG Golf got about the same (6.1-6.2 L/100). So far we have 12,200 kms on it.

Pretty close then, but I'm still dissapointed with my figures, I really expected to be able to get 1000kms out of a tank on the highway but that just won't be possible.

I too am a bit dissapointed, especially as my friend Keith used only 5.4 L/100kms from Brisbane to Bendigo in a brand new Passat CC.

I am also aware that it may get better after/from about 20,000kms.

Guy's just another thought.
Were you both using airconditioning ?

When I quoted my figures this was without aircon, I hardly ever use it.
I have worked out it uses around 0.8 Litres every 100km
But even if you take this figure off your fuel figure I still think its a bit high.
