yeah, i think they can do it, l.ol, thanks, urm, does the £280 quote sound right? Just a bit wary, as they done a full examination of the car, and are saying it needs brake pads, two back tyres (handbrake fun, lol) 4 wheel alignment, sump gaskets leaking badly.

Well, brake pads look 50%worn to me, the two back tyres have 3mm tread on them, if i let go of the wheel whilst driving it stays in a straight line and the tyres are wearing evenly, and the sump gasket isnt leaking as its never dripped a drop of oil since weve had it.

Im just slightly wary, incase its just a cheap sensor thats a 5 minute job, is there anything i can do before i take it, so i know whether theyve definately done them? I hate having to take it to a garage for someone else to fix.

The tyres and alignment you can get checked by any garage, tell them specifically you only want the injector's looking at, and make sure the invoice/receipt says that this is work to fix the fuel consumption issue and error code. Then if it doesn't work you've got a fall back for it.

To know it's been done you could mark lines on the injector clamps or fuel lines to see if they've been moved, and make a point of telling them you want everything that they've changed when they've done the job, (as you've every right to request).

job done, went for a drive along the motorway, at a constant 60mph, and was averaging 68mpg according to the computer thingy, but filled the tank tonight from the petrol light being on, took a note of how many litres went in it, and the mileage, so will work it out when the petrol light comes on again and see if the computers telling the truth. Another thing, is it normal for the computer to be constantly changing the mpg figure, like every second?

the mpg gauge will level out after youve done more miles, when its a more of an average that way, when the trips reset it will go mad for a while

If its like mine on a VW Passat there is an average mpg figure and a real time mpg figure which does constantly change, this must be what you are seeing. There should be an average mpg reading as well. Best to consult the vehicle handbook to see what is what.

just had a quick browse, what would cause excessive fuel consumption.

Excessive fuel consumption *Brakes binding. *CHECK the braking system. REFER to Section 206-00 Brake System - General Information.
*Vehicle overloaded, or excessive wind resistance (roof racks, towing etc). *ADVISE the customer about the effects of overloading the vehicle and wind resistance on the fuel consumption.
*Air cleaner element blocked. *INSTALL a new air cleaner element.
*Fuel system leak(s). *CHECK the system for fuel leak(s). REPAIR the system as necessary.
*MAP sensor. *REFER to WDS.
*Incorrect engine oil. *INSTALL a new oil filter and designated engine oil.
*Generator. *REFER to Section 414-00 Charging System - General Information.
*EGR valve stuck open. *REFER to WDS.
*Air ingress into the fuel lines. *REFER to Section 310-00 Fuel System - General Information.
*Incorrect valve timing. *CHECK the valve timing. REFER to Section 303-01A Engine / 303-01B Engine / 303-01C Engine / 303-01D Engine / 303-01E Engine.
*Turbocharger.
*Turbocharger wastegate actutator. *REFER to Section 303-04A Fuel Charging and Controls / 303-04B Fuel Charging and Controls / 303-04C Fuel Charging and Controls / 303-04D Fuel Charging and Controls / 303-04E Fuel Charging and Controls / 303-04F Fuel Charging and Controls - Turbocharger / 303-04G Fuel Charging and Controls - Turbocharger.
*Low cylinder compression. *REFER to Section 303-00 Engine System - General Information.

sorry its hard to read but all the information is what ford would use to to trace fault
*Fuel injector(s). *REFER to WDS.
*PCM. *REFER to WDS.

Depends which setting it's on, you're on real time, if you drive at 60 then coast down a bit it'll prob read 99.9mpg, (not injecting fuel).
There should be an average reading one display either way if you press the display buttons.
