2.0 TDI 170 Fuel Consumption

[Vwsteve76]

not hanging around all the time and i can get 38mpg, now while this seems pretty rubbish it really is not hanging around. drive normally and high 40's are normal, drive really economically then 55's are easy.

I used to fill up every time i needed fuel, now its never more than £25 a time.

half a tank of fuel weighs a lot less than a whole tank obviously. less weight, higher fuel economy.

Ive had my A4 2.0tdi 170bhp 4 weeks now, love the car but bit sad about the fuel consumption around town im getting 35-36mpg on a long run 48-53mpg( that im happy with) bit the combined im getting 40-42 but im putting it down too the very cold weather we are getting at the moment.

but im going to try just filling half a tank too see if it makes any diffferent`s to the MPG, like the last chap said a full tank od fuel is lot of weight so that means more fuel to pull it around.

In my VW passat 1.9tdi 130bhp used get 40mpg around town, around 55mpg on a run and 46-48 combined so hopping the A4 can live up these mpg too but some how i dont think it will.

Mine was remapped to 170 BHP.

and I average 52 mpg (mainly motorway and some town) I get approx 650 miles to one tank.

A remapped 140 will be more fuel efficient as it's not as powerful as the 170. The 170 actually pushes out a lot more than 170 as standard.


FYI my new CR 170 averages 10 - 15mpg more than the PD version.

I have a 140 model an I usually get around 36-42mpg
depending if its motorway miles....even when the display
keeps saying im averaging 50mpg PAH!

I've got a 56plate 170 and average 42Mpg with mixed driving (some with a pretty heavy foot...) If I'm really gentle on the motorway I can hust about get 51Mpg out of it... Not nearly as good as 130bhp golf though where I averaged 54Mpg over 5k miles!

[prolfe]

The newer CR is much much better for fuel. I've averaged 55mpg which is very easy. I know that the PD would of been around 40/42mpg.

Hi all,

I have just had my 170 remapped. My overall trip (option2) was displaying 38.8mpg with mixed driving for a month b4 the remap. I have now reset everything and will let you know the post remap results after a couple of tanks have gone through.

Cheers.

Keeping your tyres PSI right with weekly checks is another good tip as is not having air con on. You can also radically improve your mpg by knocking it into neutral on downhill stretches, not in the advance drivers guide, granted. I appreciate you're all talking about what the engines can 'do' but some of these suggs may help get yours up (so to speak) ;-)

I would advise against putting it in neutral when going downhill, instead put it into the highest gear that you can - this way the engine use zero fuel. If you have it in neutral it requires a bit of fuel to keep the engine idling. This was confirmed to Clarkson on Top Gear a few years back when he did the London->Edinburgh->London trip in a 4.2TDI A8 with a single tank of fuel!

Ok guys, here's my input.
Car is A6 2.0 Tdi 140bhp, had this remapped to 176bhp by Audi from new at a hefty cost too.
Anyhow I now do a mix of short start stop journeys with the odd longer one thrown in, currently getting 38.7mpg.....the bulk of this is ALL stop start around town.
When I used to do predominately longer motorway journeys?
The boot is stacked full of all kinds of work related things, and weigh a fair bit. A/C is ALWAYS on to avoid the foul smell that can occur if not used regularly and I ALWAYS use cruise when on long runs too.
If I had to guess the absolute average I'd be looking at 45mpg-47mpg generally and no worse than 42mpg.
The best ever?
I tried to see what was the absolute best I could achieve on a long run. Left Galsgow with the tank brimmed and set off to Derby all at 75mpg with a few runs at 130, picked up my mate and headed on to Swansea all at 75 mph with some roadworks at 50. Left there and back to Cerby where i dropped him off and refuelled a little later with 52.1mpg showing and a total of 695 miles with around 40 left in the tank. When I refuelled display showed 915 miles if driven in the same style on the same journey

Personally speaking I think thats pretty damn good for such a big heavy car
