2.0Ecoboost 240hp engine failure

rado041 · Jun 4, 2014

I have very big problems with my 2.0T engine. I have 3rd engine in row in my mondeo. First changed in warranty at dealer. But second at my own expense. Dealer wont help me. And 3rd engine started with same problems.

Have you ever heard about this?

Nick · Jun 4, 2014

Never. Wow, third engine. Do you happen to know if when they replaced the engine, was it just the short block, or everything?

rado041 · Jun 4, 2014

injectors,full block and head were changed. no turbo,cooling system and others

Nick · Jun 4, 2014

Piston damage on all three engine failures?

Please excuse my brevity, sent from my Sony Xperia

rado041 · Jun 4, 2014

3rd engine is still going,but started with problems like 1st and 2nd engine. Power loss sometimes,tearing.

But first and second engine,yes piston damage in both cases.

rado041 · Jun 4, 2014

On left:no interventions, series engine

On right: K&N Filter and remap to 260HP

First failure at 66000km

Second at 15 000km

Wow. Looks like manufacturing defects or unsuitable materials to me. No way that kind of damage should happen regardless of a mild remap and a Cone filter.

I'm very disappointed that Ford didn't at least contribute to the second replacement.

Just to clarify, How many engines in total has the car had? You say first new one was paid for by them, so that's two engines, second replacement by yourself, which is three and now that one has issues, so would require a fourth engine. Is that correct, or have I misunderstood and the total number of engines that's been installed in the car including the original is three?

Has anyone heard of similar problems with the 2.0 eco? It's a bit rare in the UK compared to other places like the US etc so maybe not enough numbers here to get a person to come to a forum to discuss it, though it may well have happened to several people.

I work at Ford's Powertrain development, Dunton, if problems crop up with engines already in production, then dyno tests are run again to investigate the problem, I've heard nothing about such failures with the 2.0 Ecoboost, but then again, the engine may have originally been developed in Germany or Turkey so any rework would be done there. As this is pretty much the same engine as found in my Focus and Mountune would have done their own dyno testing to develop their MP275 upgrade, I'd be surprised if these failures were a result of the remap.

rado041 · Jun 5, 2014

Now there is a third engine in car including the oroginal. So if actual engine will fail,it need 4th.

I wrote and call to Koln Germany, said they solve only german clients. With Slovakia importer and dealers no speech! They decline to accept my car to service! I was personally in Budapest Ford´s centrale for Europe..Nothing , no speech with them.And approach to the client in Slovak services its a disaster!My actual engine were changed at CITROEN service!Its a shame for FORD!

Third engine is still mobile, but began to have problems exactly the same as it was in the first two cases.

Part exchange it at a dealership for another vehicle whilst it's still running?

rado041 · Jun 5, 2014

I didnt understand this question, can you explan it better? thanks

I think it was more of a suggestion, part exchange the car while its still running.

Ahoj Rado!

Any updates since your last post? Looks like my father has exactly the same issue on the same engine just after 35 kkm.

Hi, only just spotted this thread.
Yes the problem is "reasonably" known in America re the Focus ST250 and the 2.0L Ecoboost Fusion (Mondeo) which has been out sometime over there.. There is a hell of a lot of it on the American Focus ST250 site.
I think in most cases its on tuned units and of course their fuel is not as good as UK stuff.
In most, if not all cases, it is No 4 piston that fails and normally there is no bore damage.
Most say that they are driving along normal then a misfire suddenly starts without any prev warnings and hey presto.
Its amazing the number of American owners who admit to taking car back to dealer with thr remap etc still on and then moan their warranty claim is turned dowm.
Would be interesting to know what Rado041 has a remap or not and what grade fuel he uses.
I only ever run on Tesco momentum or shell v power from new.
I will see if I can find the exact thread re the American site. Its pages and pages

I think you'll find that your confusing the US rating with the European rating. The US rated 93 Mon is the equivalent of our 97Ron fuel.

Have a look at this American site about piston failure. www.focusst.org or

http://www.focusst.org/forum/focus-st-garage/

When you are in the Garage Section scroll down about 3 headings to the line "Focus ST Maintenance"

Click on this sub heading, and then go about 4 rows down and click on the heading "Blown Motor Resource Thread"

Pages of the dam stuff.

Keep calm and drive on.

Hi Neil, Yes, you are of course right about the fuel, my apologies

I have suffered the same fate with my 2013 Ford Focus St, my modifications to the engine are 2xs racing cold air intake pipe and steeda symposer delete blanking plate. Fords have refused my warranty claim stating the steeda symposer delete blanking plate has caused excessive pressure within the inlet manifold which in turn has produced excessive heat breaking the piston. I really dont think this is correct can anyone assist?

Hi Daren,

Been off line for a few days so only just seen your post.

Unable to help you really. The American Focus ST site has about 120 pages and there is nothing concrete even on there!!

Our UK focusstoc site details 2 or 3 failures but the guys were out of warranty and had new forge pistons fitted.

Some say there were a batch of "chocolate" pistons.

Only thing I can agree is that they are wrong to turn your claim down for the reason stated.

Pity you did not put it back to standard before it went in.

Did you experience Low Speed Pre Ignition (LSPI), or Low revs Pre Ignition is a better description I think.

A number of USA guys tend to admit that they do as, because of the torque, they tend to floor the throttle at low speeds but use 5th or even 6th gear.

Obviously it is fatal to ignore LSPI (known as "pinking" to some people)

Again low grade fuel is a no no.

If you do have to cover costs it is pretty certain you will only require the appropriate pistons to suit the bore size of your own engine

wilko7 · Mar 20, 2016

Thanks mate, yeh i jave heard the pinking before but didnt on this occasion as i had the music up. I was in 3rd gear accelerating to about 80kmh from about 50ish. The sound i heard which i now know to be pinking i put down to a loose bolt on the cai as i didn't know any better. Any idea how lspi can be proved ? Yes i wished i had put both oem cai and sound symposer back on. But didnt think i would of had an issue. O well lesson learnt i suppose. Being honest isn't always the right way.

herrbohnen · Mar 26, 2016

any mods on the engine will render your warranty null and void especially if you turn up to the dealers and admit having modified it and or leave the mods on .

dorsetsi · Sep 3, 2016

Just had the same failure on my Mondeo 240ps:

Car has done 37k miles, no modification that I am aware of (had it 18 months since 16k miles). First garage I took it to immediately diagnosed an engine replacement, but thankfully, facing a short engine repalcement cost of 6-7k i was persuaded by a mate to take it to another garage that were not afraid of getting their hands dirty with rebuilds. Whipped off head and found no bore damage, just the piston damage you can see. Secondhand piston installed and Terraclean to give the injectors a clean out. Picked up today and runs like a dream again. However I am now concerned about the same fault occuring if this is a design/software fault with these engines.

I must admit that I only put Tesco standard through it, with the odd tank of Tesco premium. I have been advised to use better quality fuels in future.

TreborB · Sep 3, 2016

Hi, well I guess you have read the thread. There is nothing definite whatsoever pointing to a design/software fault on these units.
I am also a member of FocusSToc and nothing concrete on there either.
A couple of ST guys have had failures, both cars were modded. Since replacement pistons they are motoring on, no probs.
I am at 49k miles mostly A roads and motorway. I never thrash the car but I do not hang about.
I have always run on Tesco Momentum or top Shell BP stuff.
Have you ever had any "pinking" probs also known as Low Speed Pre Ignition (LSPI), or Low revs Pre Ignition is a better description I think.
The worst thing you can do if the engine starts "pinking" is NOT to take your foot off the throttle.
When was your veh manufactured.
If it was me I would just carry on as normal now but always use the better fuel.
Do you mind advising who the nice repairer was who replaced the piston(s), thanks

dorsetsi · Sep 3, 2016

Thanks, I am hoping that if I look after the car and use better fuel I will avoid problems in future. I dont think I have ever experienced plinking, although I have a feeling the failure happened whilst my wife was driving the car.

The car was registered Sept 2011. Like you, I dont thrash it about (kids and wife often in the car!), however i do use the boost and have a bit of fun with it when conditions are appropriate.

The garage was these guys here:

http://http://www.dayspeed.com/

Cant recommend them highly enough. The guy that runs it seems a real enthusiast (think he grew up tuning Peugoet GTis) and they know their onions in terms of engines. They sourced a piston and re-sized alternative rings for it as you cant get them new. Also, doesnt hurt that their labour rate is nearly half that of my usual dealer. Needless to say I will be using them for everything in future.

TreborB · Sep 3, 2016

Thanks for the info.
That garage sounds pretty good. http://www.dayspeed.com/
Well worth keeping on my favourites list even though quite away from me.
I note your year of manufacture. From the Focus ST site their is a bit of an opinion, repeat opinion, that there may have been a bad batch of pistons at one time but no one has proof.
My car was manufactured Feb 2011 (that does not mean when eng was though)
It is No 4 piston that is known to be the culprit that fails, guess yours was to.
Please update if you have future probs.
Drive on and enjoy.

Added - A couple of guys with Focus STs had their repairs done by fitting forged pistons and rods but I think parts alone are around £1k.
Another popular thing to do on these is fit Denso spark plugs ITV22.
They are 1 grade colder than original fitment and now the std recommendation by Denso
