I can't get any better than 47mpg (~17km/L) and mine's got an economy 'box' on it .

And that's only under ideal conditions.

I can't get any better than 47mpg (~17km/L) and mine's got an economy 'box' on it .

And that's only under ideal conditions.

 

Is that measured or as reported by maxidot?

 

Just thinking that as you've got a "box" on, the reported figure may be quite a way out from the actual figure as the "box" will be causing the car to put in a different amount of fuel to the amount it thinks it's putting in. i.e. if the ECU tells the injectors to put in 1 unit of fuel, the box will intercept that and might tell the injectors to put 1/2 a unit of fuel instead - so in this example, the actual consumption would be 1/2 what the ECU thinks it is/would display on the maxidot

Double, shirley?

Unfortunately quite the opposite.

Fill to fill lucky to get 6L/100km.

Eg, at a genuine 90kph maxidot indicates 3.8 but that's massively distorted by the 'box' as in reality under those conditions the actual must be approximately 5.5+.

Under ideal conditions I can just scrape 1000km from a brim to brim fill calculation.

A 'power box' it is .....economy, not so sure.

The maxidot is so out its useless unless you want a laugh.

Hmmm.

 

What was it doing before the box was fitted?

 

At 55mph/90kph cruising I'd expect my 170 4x4 manual to return mid to high 50's on the maxidot, 

 

1000km brim to brim doesn't sound that bad though. I'm sure even my optimistic maxidot only reckoned I was going to get 850km when I brimmed it yesterday.

 

Time to break out the notebook and pad and keep some records.

Double, shirley?

 

Err, no.

 

If the ecu says put in 1, but the box (sat between the ecu and the injectors) takes that 1, throws it away and instead tells the injectors to put in 1/2, then the car is actually using 1/2 the fuel that the ECU thinks it is. The Maxidot will display based on what the ECU thinks is going on, not what is actually going on.

 

That make sense?

I didn't wait long to fit the box but from what I drove it wasn't much different if at all.

Basically unless you're going to do a lot of grunt work the diesel's premium price is not worth the worry once beyond say 200k if that.

If that fact starts to be realised by the second hand buyers, the depreciation loss will be even bigger because, at the moment, you get back some of your 'premium' when selling/trading.

The very best petrol engines are simply making the diesel questionable once it's out of warranty.....for extended warranties I'd be checking the fine print v carefully......don't forget that's another cost that has to be retrieved with superior economy.

I've got a thread on the VWwatercooled diesel forum relating to the CR engine asking for those owners to 'boast' how many kms their car had done trouble free......the responses so far have been <100k which in the past would have been just fully run in with no thought of a ? of reliability.

Don't get me wrong I'm not anti diesel it simply doesn't add up financially for longer term buyers but for those who have the ability to write off the costs it's not such an issue.

Personally I think we're in the last decade of light vehicle diesels and maybe even reciprocating engines which will certainly make a lot of us nostalgic.

Toyota is putting it's eggs in the fuel cell basket and poo pooing battery so interesting times ahead.

100k km's = 62000 miles.

I think you will find plenty of Yeti's and CR engined VAG cars that have done well over that mileage with absolutely NO problems at all.

My brothers 2.0 TDI is over 130,000 miles now and never missed a beat.

That's what I want to hear although I suspect not many owners hang onto their cars for long enough and once severely depreciated trade in for a much more advanced model......what happens to the old one longer term is of interest to me however.

I wonder how many forum members have bought a high mileage second hand one and have put further high mileage on.

At some stage we will inevitably end up with just one car and then it will be a decision as to which car to sell, based on which is the best long term economic proposition .....not just on specific fuel consumption.

We love both.......it'll be a hard decision.

We had that decision. My wife liked the yeti much more than her golf but there was a better trade in with the yeti and when the first rust bubbles appeared on three of the doors decision was very easy

My wife drove from Oxford to Staffordshire last week, the Maxidot read 78 mpg, on previous trips that equates close to 70 mpg, when we have done a brim to brim.

I was in the car too, I am no light weight lol...with luggage, full size spare wheel, tow bar fitted, so all in we were probably carrying 300 kg inc people and luggage, and spare wheel etc, we were not held up too much by traffic, A34, M40, M42, M6 toll...

The car has now done 11,000 miles, since December, she rarely went over 60 mph, and avoided using the cruise control, as that kills the economy, she sets the Maxidot to show consumption, lets it gain speed down hills, and backs off going up the slight inclines, something that the cruise control cannot do.

The road was dry, and the aircon was on for 10% of the journey, even though it was early evening, headlights were on for the whole journey.

Wet roads must reduce the economy, after all you are atomising water that the tyres have to pick up, thus taking energy.

We are now well pleased with that.

The best I ever got from my Greenline was 53 mpg.

How long did the queue of traffic become when you were slowing down on the inclines?

I did the first Brim to brim on my new 150 TDI yesterday.

44.3 mpg.  The maxidot said 47.8 mpg.

That's looking very good compared to the 48 mpg I used to get from a Greenline Yeti.

I'm now getting virtually all the performance of my first 170 TDI which managed 40 mpg.

One thing I have noticed is how freewheeling the new 150 is when I lift off the accelerator.

A combination of the new low friction engine / Continental tyres and Haldex 5 transmission I suppose.

Wifes 2nd 110 se yeti is now doing 35.7 mpg around the doors according to maxi dot. Tank to tank fills confirm its not far away. First yeti did 43.4 mpg. Been back to dealers who say there is no fault codes so can not do anything about it. Customer services don't seem to bothered either.

My 110SE is doing about 47mpg, had some good long runs in that though

I have just found this from earlier in the year. heavy traffic from Essex to Merseyside meant I had to drive at 50/55mph.

A brim to brim mpg was from memory high 60s.

Gee - it must be a nightmare for other road users to follow you as you continually change speeds on slight inclines and descents. Is it really worth the angst to get those few extra MPG? And why get a car with cruise control if you don't intend to use it? The beauty of cruise control is that traffic moves in unison without bunching at an optimum speed, the problem is that few drivers use it properly in the UK.

I'm an 'economy' driver and know all the tricks but mine has never cracked the equivalent of 50mpg under THE most ideal conditions and speed.

You can't be trying.

I was regularly seeing over 50mpg on the Maxidot on my 48 mile commute to work, even in the winter.

Oh I'm trying to the point of OCD but fill to fill the best I get is 17km/L.

BH!! that is only 40mpg!!

17 x 4.545 = 77.265 km = 48.2mpg (imperial)

The maxidot doesn't know what gear you're in either ....it simply measures the injection period.

It will tell you crawling in third is more economical than sixth at 80 frinstance......it's an entertaining 'toy'.

(Kph of course)

In US gallons it is, in UK gallons it's 48.0217803
