#1: Poor Fuel Economy 2.0 HDI Author: propaintballa, Location: Weymouth/Leamington SpaPosted: Thu Feb 09, 2012 3:25 am ---- Hey guys...
My fuel economy has been getting worse and worse and it's really starting to get to me as i regularly do 180 mile journeys...
The car has a Pro Steve Remap and a decat, straight after the remap I was able to get roughly 100 miles to 1/8th of a tank where as before the remap I was getting 60-70.
Baring in mind, I don't really do a lot of driving in town at the moment but when i do it seems to rinse fuel even more than it used to :/
It has recently come up with the little spanner on the odometer, so it's indicating that it wants a service and my injectors do tick quite a lot. Can these problems combined really cause such dramatic effects?
I don't want to spend a poo load of money on this POS car for it to make little to no difference. I tried injector cleaner a couple of months ago when i first started to notice poor fuel consumption, but made no difference.
Another thing to note that the car did a month or so was pretty much lose all power whilst driving along, it would then pick up speed and drop off again, a similar kind of feeling to driving a petrol car with a faulty coilpack.
Any help on this would be great as paying £1.41 for Diesel to get 45MPG seems a bit retarded to me.
Thanks guys

I'd do a service then if it doesnt improve i'd get a diagnostic done.
EDIT: Just read the bit about the power loss, get a diagnostic done instead of waiting.

#4: Re: Poor Fuel Economy 2.0 HDI Author: propaintballa, Location: Weymouth/Leamington SpaPosted: Thu Feb 09, 2012 3:38 am ---- Mmmm, i'm thinking i might get a diagnostic done first just to play safe rather than spending £50 on bits to find the engine is going to explode soon
Have no idea where do diagnostics around here though tbh -.-'

I will check that but i seriously doubt a slightly clogged filter would cause a drop of 10-15MPG... Unless some form of rodent has been sucked up lol!
Fuel filter is another thing but i can't undo the god damn cover on it!

I cant recal from memory if it is the 2litre engines, but im sure one the HDi engines are known for trying to eat there own air filters. Basically sucks the filter up the intake pipe causing a restriction.

What the hell... If it's something as lame as that, i'm going to punch myself in the face...
I'll take a look and report back later! Thanks

Maybe before the remap, but like i said, since that i've been able to achieve 60+ on a long run...
I'll try the fuel filter again, but I don't have any of my tools so i doubt I can get it off by hand, i tried a few weeks ago
#10: Re: Poor Fuel Economy 2.0 HDI Author: 2Oh!6, Location: GloucesterPosted: Thu Feb 09, 2012 7:15 am ---- You used to get 800 miles out of a tank?
#11: Re: Poor Fuel Economy 2.0 HDI Author: Dutch-HDi, Location: West MidlandsPosted: Thu Feb 09, 2012 9:26 am ---- most i got from mine on a long run running driving very conservative ( relitives in car lol) was 640 from a brimmed tank ussally get around 500/550 ish

I used to get about 550 that was 340 motorway and the rest town ish driving... After the remap I was getting 85-100 miles to a tank, yes... However, its probably nearer the 85 mark because my last quarter seems to disappear quite rapidly and the car has run out of fuel before when it was half through the orange, so could be a faulty fuel gague...
But that's besides the point, I'm still noticing that its using more fuel than it used to lol

Trip computer on the multiplexed 206 is pretty accurate.
