Any sugestion more than welcome 

HELP PLEASE

1130 could be legacy from your fuel rail problem although I would have expected the garage doing the work to have cleared the code. At half(ish) the MPG expected it suggests you still have the same problem and are over-fuelling, your air / fuel mix must be all to hell or you drive round locked in low gear.

Hi

Thanks for your replay.The gears are shifting without any problem -it must be something wrong with air/diesel mixture-the only thing is why the computer is not showing anything and when you play with the key the code is coming

The key dance only shows only the most basic ODBII codes, nothing much use, just the bare bones. All cars these days are in fact 4 different interacting computers. In your case you spent on the fuel [ling] system, my 'starter for ten' is you appear to still have a fuel [ling] / air mix problem. A decent diagnostic scanner should narrow down where to look, many garages have a decent diagnostic scanner, any do not. Best of luck.

Hi.

Thx -now i have to ook for good garage to diagnose the problem

[gordy]

With no undue smoke or running problems only thing I can instantly think of is engine temp sensor telling ECU it's still cold. Service item like air filter should be nice and clean of course. There's been a few of these high mpg issues mentioned on forums, but, if there was an answer, we're not getting to know.

cool will  have a look in to the temp sensor us sometimes is overheating -not much but above  half of the gauge.

thx

Most people in the 2.8's never get to 1/2 on the temp gauge in the winter and have to airdam-MOD the front of the grill myself included. Winter MPG is always going to be less than summer MPG, in my case my 33.9 uptill-down dale is always 3MPG less in the winter than summer and my car has an additional Webasto auxiliary heater [thankfully] fitted. Most cars never ever have the anti-freeze checked let alone [front] flushed and replaced with new G05 & distilled water only, particularly once a car is over 3 years old the engine oil, brakes, filters, and highly hydroscopic brake fluid is neglected. Garages will stick any handy type of available fluid in any hole and don't care a hoot - why would they - how would you ever know. For myself I was ashamed when I did a complete cooling fluids flush on its 5th year of low mileage life including the matrix only to find a whole lot more solids and gunk - an unanticipated find in an alloy rad. If yours goes to 'just above' the half consistently that's not overheating, a knackkered stat is designed to fail in the open position [in which case it would stay cold for ever], that suggests your stat is working.

Hi.

Cooling liqiud was changed 2 weeks a go toogether with injectors they where recondintioned,In the garage they flushed the cooling system few times.in few weeks time im going to replaice againg coolig liquid for new one.the garage said to let the new  clean cooling liquid to work and clean the system properly, then we exchange agian for new one-mid of januaryi should go to replace it.

The high fuel consumption is only when i drive in the city,when i do motorways the computer is showing 6-7L/100km

thx

All codes cleared,all injectors reseted -after driving 20 milles the code pop out again P1130

Sorry can't help with your problem but I'm wondering what mpg you guys get.

 

My gv- 2005 2.8crd ltd xs with aux heater - averages about 24mpg. Always has. Will do 30+ on a long motorway jaunt but i do a mix of town & dual carriageway most of the time.

is mine especially bad or is that about normal.

[voyager2006]

Around town 25 mpg. On the motorway we have had 39mpg. At the moment its doing about 1000mpg as its not going anywhere

[soupstone]

I'm about 26mpg on average, lots of shorter journeys, longest run normally 8-14 miles one way. That's the 2.8 auto with heater.
I'm just off on a 420 mile journey, I'll fill her up and see what I get on a run. 

My 2.5 used to average 33mpg, manual box and no aux heater.

[bignev]

Just a question fellas, are you calculating fuel consumption or trusting the computer, which is going to be optimistic. My petrol / gas one is around 1 or 2 mpg up - quite a percentage round town that on these!!! At 16 ish in the cold. But on gas most of the time of course

 

But my second car, a 2007 Galaxy, is a bit worse, reckoned 52 mpg, but 420 miles on 46 litres..........my maths says 42 mpg, lying toad Ford.

[soupstone]

I normally calculate it. Whenever I do, the computer is normally sitting a couple of MPG higher.
I'm on 30.4mpg for 400 miles yesterday, I'll fill her back up later and work it out more accurately. 
 

 

Edited to add, worked out at 28.36 mpg

I just go on what the display gives me. I don't have the time, patience, or inclination to work it out. I know a few people who have reams of spread sheets charting fuel consumption from the first time they ever put fuel in their austin a40, but i just can't be arsed to be honest.

Fair enough that is pal!

I am pretty sure that my galaxy is very extreme in its optimism.

 

A dead simple method to get actual values - when the fuel light comes on, reset the trip meter straight away.

When you can, fill up with 45.4 litres - 10 gallons. Drive the car as usual !!!!!!

When the fuel light comes on again see how many miles it's done and divide by 10, = mpg. Simple.

And just repeat if you can be arsed or are interested enough, say if you are going on a reasonable drive.

 

Yes sometimes the light may come on a bit early if the car is stopped on a slope for long enough, so not always going to be hyper right. If you have a steep drive that will cock it right up!!!
