I’m getting the same problem with my 1.6tdi spanner comes on it Stops being able to accelerate if I depress the clutch the engine cuts out, turn the ignition off whilst still in gear and turn ignition back on it clears and am able to drive again, but if I try taking it over 3000 revs spanner comes back on and I get the same problem, but it only seems to be an intermittent fault

That is a fault with the engine as you are getting a warning on the dash.

Yeah I know the manual states it’s a drivetrain issue, no dtc’s tho this is the problem, I believe it to be turbo issues but not sure until I get it terra cleaned to see if that sorts out any sticky variable blades on the turbo

I also have an issue with my 65 plate manual 2.0 diesel 180hp cutting out on the motorway. Started last year at Easter, first run out towing my caravan - I know, I know, that my first problem but look, the staple tow car is the 2l Mondeo diesel estate, I even opted for the 180hp to give a little bit more grunt pulling.
Good Friday, 2016, travelling from Nottingham to Torquay it first cut out at the top of the A42, then several more times so stopped at the services near Ross and the AA saw a fault for the gas recirculation valve (have been there with a Passat excatly a year previous, on the same journey), the patrolman disconnected a senor lead, tthe cutting out was happening with the cruise control on and off and the limiter on and off, by the time I got to Torquay It was still happening so took to Fords in Exeter, they had it Tuesday to Thursday afternoon and serviced it (it was booked in for the service at a dealer close to home for the following week but the lease company agreed) and "fixed" the fault with a new fuel filter, I said "Thank-you very much, I was really worried it was going to be something major", and put it down to being bang on for its service so drove the car back to the caravan site.
The following morning I set off back home, van in tow, and the engine cut out on the first hill - thanks to the cop in his X5, with his blue and red lights for escorting me to the adjacent layby, I called the AA who relayed the car and van back to Nottinghamshire. After the weekend, Took the car to the garage, local to home, who couldn't find anything other than a fuel fault code.
In the following 3 months it went back and forth to the garage, in the end they did get to experience the fault and got stuck-in, contacting Ford technical, and took the fuel tank out to find a black sandy type substance in the tank that had clogged the pump and filter in the tank and under the bonnet they replace 4 fuel injectors.
Everything was fine for 8 months and then the fault returned, as before, generally under load, with and without the caravan, mainly overtaking coaches and HGVs, although once in town, going up a slight hill, at 35.
Within the last week a new fault has appeared where it has gone into limp mode, on 2 separate days, in coldish mornings.
Notes, engine cut out:
> Happens generally in 5 or 6th gear.
> With/without the cruise control on - but more notable with it on.
> The fuel contamination - I have a fuel card so was going to main stream Shell when the fault first appeared but now go to main stream BP, so different garages across the UK, using standard grade diesel.
> Generally haven't changed gear but giving it light throttle; lately I am on edge so do go a little gingerly - no hard "giving it the beans".
> The orange spanner picture appears, and I loose power, coast to a halt/swerve to the first bit of safe ground as I know the car won't power it's self, once at a stop the engine is still running but really lumpy (3 cylinders?)' turn the engine off (button) the aux power notice appears, restart and continue on my way.
> The 2 recent orange "see manual" fault occurances, the car seems to be limited to 2500 revs but other than that was fine - 2500 revs in 6th is an adequate speed.
> The car is my company car, leased from a big lease company based in Slough, so sort of no expenses spared in maintence, and thanks to them for sorting hire vehicles whilst mine was in the garage, and keeping me informed on progress. Thanks also to my local Ford garage who also kept in touch whilst the car was in bits.
> No thanks to the Exeter Ford garage who didn't tighten up my oil filter during the service so on the next outing with the van I realised there was a problem by the amount of black specks/some permanent on the front of my white caravan - cheers guys.

After the Christmas break, I will speak with the lease company as my current journeys take me on several sections of trunk roads which are under repair/widening/upgrade to smart motorway with no safe place to pull over to restart, only the live lane, in the wet/dark, at rush hour and the frequency of the power loss is starting to increase.

Interesting post a few years back I had a Focus MK3 161bhp and one night accelerating hard the check engine sign came on, and power reduced on the engine to 2.5k rpm or so.

Used to go away on next start up and started happening often. It turned out to be the air filter! It was starting to compress under acceleration and turn was strangling the engine of air under acelleration. It’s a cheap fix to look at!

I’m having the same problem as Colin and Bob with my 2016 210ps bi-turbo. Engine cuts out under light or moderate load, especially frequent when trying to overtake. Engine spanner comes on and you have to pull over. Restart and its like nothing ever happened. Started 127 miles out of warranty, and happened about 10 times in total now. Stealership havent got the foggiest clue. They’ve changed the air intake manifold and fuel filter so far, but I have no confidence in them anymore (as they have also failed to solve an intermittant tyre pressure sensor warning after 3 separate attempts), and I don’t like throwing money at it until they stumble across a fix.

I am seriously thinking of getting shot of the car now as its not safe. Did anyone have any follow up on what this issue might be?

No further help im afraid. mine continued every 1000 miles, dealers had it for 3 weeks, replicated the fault but could find no reason nor fix. gave it back to me saying there was nothing they could do!


so sold the car. FL15HOH buyer beware,

I think at that speed in that gear you have effectively already stalled the engine and a gear change at that point simply confirms it. As the clutch disengages the only thing keeping the engine turning (road speed through the gearbox) has gone.

Hi all, just a follow-up for anyone else having this problem, this issue turned out to be injectors for me. To say that my local dealership was less than useless on this matter would be kind. Despite them vocally confirming that they had run a leak-off test, it turns out they probably didn’t, as when i took it to a diesel specialist, they did one and found injector no. 3 bleeding fuel away like there was no tomorrow.

As it turns out, all the injectors were leaking and needed replacing, so it was a very expensive day - but I have been running the car for the past few months with no further issues. Moral of the story, take your car to a specialist as dealerships for the most part don’t have the technical knowledge to sort out your problems but will happily take your money replacing parts that were probably ok. Hope this helps someone!
