2012 diesel Focus - is it broken?

[anonymous-user]

My wife's 1.6 TDCi 115 Focus has never been brilliant on fuel since we bought it new 2 years ago. It's now done 37k miles and on a run will get up to an indicated 48mpg. Combined (mixture of town and A roads) we are getting 44mpg which is rubbish considering our old Mk2 1.8 TDCi struggled to get below 50mpg. I know it's not all about mpg but the whole point of buying a 1.6 diesel was it was supposed to be good on fuel. It's also been a bit sluggish and thrown up a couple of "check engine" messages which the garage could never read.

I'd be grateful to learn what other owners are getting. Is there a problem, or do they all drink fuel in this way? Published Mpg is 67 top the gallon which seems like a joke.

check the air filter isn't damp

Our previous car Focus 1.6 TDCI Titanium model averaged about 55mpg Summer/winter.

B.P.Premium diesel.

Sorry, should have stressed the point - I know older 1.6 Focus models were great, ours is the latest model with the daft Eco stop start thing. From my research, I'm starting to learn I may not be the only one questioning the economy of this model. I'm really trying to work out if there's something wrong with it or if they are all crap on fuel. Dealer is telling me it's fine.

I had the same feeling with my TDCi. When I first got it I was sure 55mpg was the norm, over the last year it has gone down and done to 43mpg. (50,000 miles now )

I have taken the car back and also mentioned this when it was serviced with a similar result to you.. It's normal….
This time I made a big fuss, the mpg has never improved, my daily journey is 30 miles on the motorway so should be better.

So at the last service I paid for the car to be put on the garage diagnostic £80 !!! To which the dealer phoned and said nothing was wrong… So I suggested someone actually drive the car, which they did. Only this time admitted something wasn't right.

The result was a replacement EGR valve and according to them resetting the injection parameters.
I've not re-set the fuel economy and in a week has made it's way back to 55mpg. Not great but is going up every trip.

I own a 2013 zetec s 115 37 round town about 52 on a run exactly the same as the 205000 mile 13 year old Passat 110 tdi I had before which only had 5 gears and no stop/start. Not very impressive tbh.

Should get more than that tbh. Have you checked tyre pressures? Is it carrying a boot full of crap etc?

My 01 406 estate will do 60 mpg driven gently, 8 valve engine with no DPF, it doesn't make a lot of difference what weight I carry or that the tyre pressures are spot on but the way its driven does. I am very light footed but with normal driving it should do 50 mpg. I also have a C5 with the same engine and similar mpg but strangely the 2.2 I had was terrible on fuel, would only average about 40 mpg which seems to be quite common for this engine, no idea why.

Thanks for the replies, looks like it's within a couple of mpg of what others are seeing. I thought diesel technology had moved on but clearly not. Shame , as the old 1.8Tdci we had went like the clappers, steered better and still managed 50mpg. New car appears to be better made but the slow and thirsty engine is a let down.

Have the dpf gutted & mapped out it will improve performance & fuel economy.
The engine is sourced from Peugeot while the 1.8 is a very old design ford engine.
Modern diesels have so much crap bolted to them to reduce emissions it not a surprise it affects the fuel economy

My father-in-law has a 2012 C-Max with this engine. His car has never achieved 50 mpg, except on the gentlest of motorway runs in ideal traffic conditions. It averages 46 mpg. The combined figure is way up in the 60's.

[Mercury00]

That's really rubbish. I also have a new-shape focus with the 1.6 125ps petrol and I'm getting an indicated 43mpg. It was even higher than that before it got cold.

My old man has the same, the dpf strangles some of the consumption, the weight of the Cmax kills more and his hovers around the low 40's and has spent more time back in the ford dealer having things checked and repaired than any other car he's ever had, the garage he bought it from at first shrugged it off but as it persisted they've changed all kinds of sensors, tried messing around with the ECU and lots of other things to very little benefit apart from their warranty work bills.

I'd never hand over my money for one & my old man is so pissed off with it that he's gone from being a serial ford owner (21 years of them) to ordering a VW Tiguan.

I got a 1.6 diesel Focus in September and average 45mpg over 6000m, most I have had doing all motorway no more than 65mph was 48mpg.
Its a company car so fuel cost doesnt really matter but it is dissappointing considering my previous 1.8TDDI Focus was 50mpg no matter what.
The hire car I temporarily had before was the same.
