Hi All,

New member here, looking for help with my wife's 2013 Mk3 1.0 which is having some serious problems. The car is currently in and out of garages with our warranty company, but the cause of the issue has still not been found.

The car would drive fine for around 2 weeks, then when starting, struggle for revs. eventually the car would not start at all, just cranking/turning over:

Videos of problem

The garages perform various tests, diagnostic checks, etc and only find that the spark plugs are cracked, no error codes, they replace the plugs and we get the car back.

2 weeks of normal driving again, and the same issue returns.

Any help at all, as to what might be causing this would really be appreciated, we are really stuck at the moment...

Justin

Just at a quick glance in the Haynes Manual it says

battery terminal connections loose or corroded 

Ignition components damp or damaged

Fuel injection system fault

Major mechanical failure (eg, timing belt) 

Their is a few others listed but not relevant after watching the video.

 

I'd suggest talking to your warranty company about getting the car repaired by Ford themselves as with all the trouble you're having is just beyond a joke. I hope this is some help to you if you need more information I can take pictures of pages from the manual for you.

Hi Ryan,

Thanks for those suggestions. Regarding Ford, Ford were the 2 garage to take a look, and just change the spark plugs, ensuring us this was the problem. I definitely no longer Trust, Trust Ford.

It is now with an extremely professional approved Ford Specialist, who have re-created the problem, but still struggling to find the cause.

It seems so strange that it works perfectly after this, but only for a limited time. oh and to note, the car only has 19k miles on it!!!

Quite a few folk seem to be having deadly problems with the eco boost engines, there's a post where someone had to have the engine replaced and because he had it done at an independent he had to shoulder over £4k in costs as Ford wouldn't honour the warranty

Also, there was a recall recently bit I think that was just for the 1.5's.

Might be worth checking ETIS for yours, otherwise agree with Tasape and hand it back...

Wasn't that for the 1.5 diesel not petrol? (i.e not an Ecoboost engine)

sounds like a fueling problem. either the intank fuelpump (most likely ) or the high pressure fuel pump. can the ford specialist not check the fuel pressure on diag equipment?

This was for the 1.5 diesel yes.

I think there is a page on Facebook dedicated to ecoboost problems, over 400 members.

As someone with a 1.0L 125ps Ecoboost that makes quite worrying reading.

Only 400 for the tens of thousands sold? Less than 1%, sounds pretty good to me.

No product is free of failures.

No, indeed, and the people who frequent the discussion groups are generally those who've had problems. However, the comments about the engine being designed to run at a higher temperature and the possible long-term effects of that could be a cause for concern. To run at a higher temperature requires a higher coolant pressure and we already know that has caused problems with cracking of the reservoir and that the ECU can't detect overheating quickly enough to avoid engine damage in the event of coolant loss. It ought to have been fitted with a CHT sensor.

They've made changes to it over the years, all come with the electric overrun coolant pump now for example.

The software update as part of the recall also adjusted the parameters to try and stop it overheating, or at least warn you or go limp earlier to protect the engine.

All well and good but my understanding is that's just to prevent the turbo overheating and what about the thousands of older cars, including mine, that are running without that upgrade?

It's something you can add yourself. Ford have made it mandatory when installing a tow-bar.

I think the pump is for the Turbo, but just an example of how they tweaked it over the years. I still believe the 1.0 ecoboost is more reliable than the old DV6.

That wouldn't be very hard would it? :whip:

Sorry, my comments have taken the thread off-topic.

Suffice to say the time is past when I would feel able to contemplate such a job. Surely the pump will need configuring in the ECU anyway?

Yeah it needs fitting and programming. Local dealer quoted about £300-350 for my mum's car iirc.

When I said yourself I meant it's something that can be retro-fitted, rather than having to be from the factory. Ford have a TSB for it.

I fitted the extra electric coolant pump, and it does kick in sometimes. There was a different pcm update for coolant pump .

Hi All,

Just an update here. still no luck yet. this was not bought from Ford so cannot speak to them, if we don't get an answer soon it will be going back to the dealer we purchased it from. the specialist are current running tests on coil packs.

my suspicion however is that it is something fuel based, as IanTT suggested. either pump or pressure sensor.
