Official Fuel Economy Thread (formerly Highway economy).

[DBBL]

Thanks for your reply guys. Much appreciated.

I called VW this morning and the guy said there's definitely something wrong with the car and to bring it in. He said the least I should be getting is 500km to the tank (which I would be happy with if that was the LEAST I should be getting)

That said, I called Volkspower this morning re APR Stage 1 and asked about fuel consumption. He said that it actually improves it by between 10-15%.

Can all those with the APR upgrade please confirm or deny this statement???

[Sharkie]

It all really depends on your driving style ..... I can easily get more than 10l/100km combined out of a TDI Golf, and thats purely down to my driving style .... (when I was testdriving the 3.0TDI Q5, the computer was telling me I was averaging 14.7l/100km) .... if you are aggresive with the throttle your fuel consumption will be high regardless if you have a diesel or a petrol turbo.

When the turbo is on boost a lot (diesel & petrol) the ECU dumps more fuel in and you use a lot of it .....

Driven with some constraint, you should be getting an easy 500km out of the 147 .... if not, and if you do not drive it aggresively, then there is something wrong.

APR map, again if driven with moderation will deliver 10%+ lower fuel consumption. And again, if you use that extra power all the time, you will be lucky to get 450kms out of a tank. (Like me)

Bottom line is ... if you are aggressive with your throttle, you will use a lot of fuel regardless which car you drive ....

In my GTI I saw extremes depending on usage .... 5.7l/100km (out of a modified turbo petrol) cruising on the highway, and 29.6l/100km at the track ....

Why didn't you buy diesel?

Before you buy BMW find out how much is it for scheduled servicing and some common servicing parts incl. brake pads and brake discs.

scheduled servicing at the dealer is cheaper for a BMW than for an Audi.

15k service for a GTI at VW $450.
30k service $550700 incl wipers/brake fluid.
45k service $450

20-25k service for a BMW (variable distance/time service) $300, plus say $150 for wipers/brake fluid

40-50k is another minor service (inspection 2) say $400.

Up to say 45k on both cars, the BMW will be much cheaper as you've done only 2 cheaper services rather than 3 more expensive services.

I also find brakes, oil filters, wiper blades, pollen filters, etc slightly cheaper for BMW than VAG.

If you're not servicing at the dealer, the service + parts will be very similar, however for every 3 scheduled services for a VAG you only need to do 2 for a BMW.

Having said this, the financial cost of trading in your new VW will outweigh the savings of buying/running the X1.

(Prices quoted are real life experiences for VW and BMW, plus the fact that BMW seems to be more reliable than VAG. However this is a small sample population within our family of say 5 BMW/5 VAG)

I have never been too worried about watching fuel consumption as this is just par for the course with purchasing and running a vehicle of this size and spec.

That said, I have been recently comparing the consumption and I average 8.4lt/100km at the moment.

My 125 TSI has done 24,000kms, and I am not by any means a restrained driver. I mean, I often take off briskly from the lights, and I dont always use the best gearing. etc...

I dont thrash my car, but I do not feel that it would be right to drive it like a granny either.

If you want to save fuel, or are worried about consumption, buy a bike or prius or fiesta diesel. An SUV like a Tiguan is never going to compete with those sort of things.

Low 7L per 110km - TDI TIGUAN

Hi All

I get low 7L per 100km in my TDI Auto Tig - around town
About low 6's on the open rd sitting at 110kmph with cruise


I love this car!

[yshsieh]

Feeling is the most important.

Good thoughts!

[brh1978]

My 147's done 15000km and is a year old, Thurs we drove 350k from Brisbane to Bundy, the MDI reported 8.1L/100km and that included driving home from work in peak hour and a couple of very brisk overtaking manoeuvres (smooth trip no heavy traffic). Best we've ever done is 7.9 on the same trip (2 adults, 1 dog, luggage). My lease report from last year states we've achieved a total average of 10.5L/100km km for the last 12mths, 90% city driving, 10% metro highway driving with the A/C on 100% of the time.

[yshsieh]

16L/100km --> 90%city driving in peak hour, average speed 15km/h
The fuel is very crazy...
I just got my Tiggy 1 week ago and done around 500km.
A quite young Tiggy.
Is it the reason why the fuel is crazy?

[Transporter]

The reason is that very, very low average speed 15km/h. You should be getting less than 10L/100km in the city but it will depend how heavy the traffic is. Yeah at 15km/h that is most likely what you get with every 4 cylinder engine car with the same weight as the Tiguan.

Guys, just take the MFD witha grain of salt. It depends when you check it, how you have been driving and for how long on that trip. If you run down the shops and check it will probably read very high. The Tig system seems to reset itself after leaving it for a time (not sure how long - 1hour 2?). So, most times it's only giving you an average of what you have done on that trip - not an average since the last fill etc. (unless there is a setting I can't find, but this is how mine behaves).

So you really need to average it out using the old method of filling, then refilling and checking the OD. Of course if you're only gettin 400k's to a tank, then you have a problem - either that or you've been taking driving lessons from Sharkie!

[Pullstarter]

Prettys sure it resets after 2 hrs John, there's also 2 trip meter modes. You'll see a small number 1 or 2 on the MFD, that tells you which mode you're in. One is your overall averages the other is your most recent trip (which wipes itself after 2hrs of sitting still).

[Transporter]

The closest you can get to the real fuel consumption number is to always fill the tank to the top, note the km traveled and do it several times, than calculate it manually. I collect all the fuel receipts where I write odometer and trip meter readings, so over the time I have the better idea what is the fuel consumption of my T5. Also it can be a good indicator if there is some thing wrong with the engine or engine management (after replacing tyres you could also see some change in the fuel consumption).

Doing it manually is the only way. I generally go to the same servo and even to the same pump if l can. Fill it to the first click and reset the odometer straight away.

Ahh, thanks Pullstarter. How do you swap between the two without me spending an hour scrolling through the MFD menus ans still not finding it?

Pressing the Ok button on the steering wheel while in the fuel use/100klm screen will switch it b/w the two modes. Holding the OK down in what ever mode you are in (1 or 2) will reset it for that mode (1 or 2). I have often done this at each tank so I get the average for the tank using the MFD. In my experience after comparing actual use against MFD over 4-5 tanks, the MFD was close, but consistently 0.2-0.3 l/100 under. ie if MFD average was 7.7, actual was 7.9 or 8.0. Not sure all are the same and ours is APR chipped, but a guide.
