Does anyone know why the Ford Focus (mine is an 06 plate) has no instant mpg readout on the trip computer ? Average mpg is present but the readout scrolls straight past where instant mpg should be. I`ve searched around the net a bit and most people say it`s absent, but some others say it can reappear if you do 500miles without resetting the av mpg (it sounds unlikely but that`s what it said.....).
One source said it`s possible to get the instant mpg turned on but I took the car to South Yorks Autos Diagnostics (who can gain access to the computer) and they said they didn`t know how to do it.

I`m fairly keen to get the instant mpg switched on, I`m sure that feature helped me get 57mpg out of a hire Ford Ka when we were touring round Shetland, and there aren`t any dual carriageways in Shetland so that was pretty astounding economy !
I`d actually go further, I reckon if all new cars had an instant mpg readout permanently displayed on the instrument panel it`d probably cut the amount of fuel used in the country by 10% !

I can't answer your question but you could get some rather useful information using a bluetooth obd2 dongle and torque on your phone, it's able to give you an MPG readout and you can monitor what your lambda is doing and try and keep it in the middle (neither rich nor lean) for the best economy.
 
There is no instant mpg readout with the Focus, as I looked into it a few years ago, I think the 500 miles without reset is a myth.
 
My MK1 Focus used to have both instant and average mpg readouts and I agree instant is very useful to have.

My ST220 doesn't have it :(

Are you sure its Instant not Average ?
If it really is Instant, is the trip computer readout green or red ? Somewhere on the internet is says TCs with a red readout have it but those with a green readout don`t. Interestingly a few people on the net have also commented that French Focuses do have instant MPG. But any car that has average MPG must have the requisite sensors to give instant MPG, so that begs the question why did Ford not fit the instant MPG option ?

No way, whenever I scroll to mine I always like to see how low I can get it to go :D

Red, definitely there
 
My 2001 Focus estate definitely has it, right before the average readout. It's a 'Ghia' I think. Very useful but I do question it's accuracy some times!
 
I honestly don't understand what real use an instant mpg-o-meter is?

I look at my average out of interest when I'm about to fill up but I honestly never look at the instant readout. I even turned my daft "eco" lights off on the dash as they annoyed me (civic)
