Vito
Having a few issues with fuel economy (or lack of). £13 @ £1.38 p/l = approx 40 miles solid urban use only. Van not even quarter loaded.

I have a major ticking / chattering noise between 2+3k revs so try to keep below that. Seals were replaced on injectors before I bought the van. Just had a full service with all filters changed. No fuel leaks at all. Its been tested using X431 Diagnostic System. No error codes within engine. Injectors working fine etc.

Can you guys recommend anything I should try (Take it for emissions test ?)

Engine wise 2 + 4 Glows need replacing.

Mechanics seem to think I should be getting much more MPG than this

:crazy:

Thanx
 
Sorry - its a 109 cdi (2004 model) 6 speed Manual

:eek:

Also which power output and wheelbase? All could affect consumption figures.

Any other problems such as poor acceleration? Is the consumption improved on longer journeys?

Apologies again - 88hp - SWB (2770kg Gross)

Its the Baby Vito

o_O
 
I would suggest getting a full diagnostic carried out by an independent specialist with a Star computer.

Is the van behaving normally in other respects? does it reach normal temperature quickly?
 
£13 worth of fuel @ £1.38 a litre is 9.4 litres, or 2 gallons. If you had used exactly that amount to do exactly 40 miles then that would have been 20 mpg. You need to repeat the test over a much longer distance to get a better idea, but be aware that the official urban consumption for the 639 Vito 109 CDI with manual transmission and no DPF was 23.9 mpg when new (in the 2006 brochure I have, anyway). So realistically you should expect a bit less than that ... low 20s.

The more powerful 111 and 115 Vitos actually gave better mpg than the 109 (24.6 mpg on the urban cycle). They had a different rear axle ratio, which may have been a factor.
 
Thanks - normally ? Well yeah (there are a few lights on dash - ABS/ESP - separate thread done for that a week or so ago)

No Temp Gauge onboard so have no idea.

Anyone know any top notch indys with Star in North London ?

:doh:

*edit* Thanx BTB 500 - Jeez - even when new those figures are awful...

Surely there is a temperature indicator available by going through the instrument cluster?

Unfortunately that will only illuminate if the temp gets too high...

Yes, 20mpg is standard fare for a 639.

Funny thing is, the far more powerful 115 does the same if not better!
 
Stop/start consumption isn't great but we get around 30 mpg from ours on a decent run, and that's the V6 auto:

 
Like others have said, 20mpg is not exactly horrific, especially in a bigass van. I get less than that in most of my cars!

I can't believe there are still manufacturers that don't fit a temp gage and just have a 'engine cooked' lamp instead. I thought that practice died out with its last user, French manufacturers, in like the late 80s.

It's not a 'big-ass' van though.

Mercedes vans (Vitos and Sprinters) are famously woeful on fuel, their one and only selling point is the longevity of the engines and their LWB hi-Top is bigger than their competitors.
 
Our sprinters have returned 15mpg in town and 25-30mpg on a run, that's been spread across long term ownership of 5 different sprinters, over a million miles with many different engine and body configurations.
The only one I've chosen not to include is the V8 conversion.

I have never thought the consumption was bad considering the size of the vehicles and the comfortable 70mph cruising...

We have run a few Vito's as well, the 638 cdis would regularly return just under 40mpg on a run to london and back.
 
Pfft...you Europeans don't know what bad gas mileage is :p.

I guess, a van is still a van, its never going to be really good on fuel, unless it has some kind of super tiny engine and is mad slow. You are still moving a large heavy brick against the forces of nature. And urban driving is especially bad because you are constantly stopping and starting, so you use up all that energy to get moving and then waste it all by stopping 200 yards later and then get moving again and etc etc, and since a van is heavier/bigger than a car that counts more I guess, thats what uses up all the fuel.

I guess there are more fuel efficient vans out there, but at least you get Benz build quality and driving, right? I mean, sure you could probably get 30mpg out of some Fiat/Citroen, but, what would you rather be driving, a Fiat or a Benz?
 
Have you tried some fuel system cleaner. I try and do it around every 3/5k miles if I remember. If your having other faults coming up on the van make sure their not connected.

Ive got a 111 LWB and get around 30/33 mpg with mostly urban and a bit motorway. The best I have achieved was 39 mpg, traveling accross france for hours following a coach closely, very boring but worth it. And as for the Nurburgring lap it was around 12mpg :rock:
