Focus 1.6 tdci 2010 engine malfunction

aldub83

Hi can anybody point me in the right direction to fix this? Engine cuts out and had no power in high revs.engine malfunction comes up on dash but still drives.when you turn off and turn on again it goes away for a while.
Thinking blocked fuel filter?egr valve or something with turbo maybe

Fuel filter would be first fix.

Fuel pressure can be easily checked with a scanner to read the live pressure under acceleration.

Get it plugged in. Engine cutting out would look like egr valve.

mullingar

Egr's tend to be open during idle. But low power on high revs could be egr not closing fully. So yes, egr might be stopping half way and causing the trouble too.

EGR and turbo is prbably about to eat itself alive.

These 1.6 ford diesels really are dreadful engines. They are very soft and don't stand up to any kind of abuse at all.

tbh, i'd fix and get rid asap if i were you.

The 1.6 is actually a good engine. Its biggest weakness is the owners who dont service the cars properly.

It the same engine that Peugeot, Citroen, Ford, Volvo, earlier Mini's, Suzuki, Mazda use too.


EGR's fail on every diesel.

I don't agree to be honest.

for most people a car has a status marginally above that of a household appliance. They ought to be designed to withstand harsh treatment and neglected servicing.

There are many engines out there that will have are robust enough to withstand an amount of abuse and neglect that is representative of real world driving. No everyone is OCD about a service booklet.

The 1.6 cannot do that, it has to be treated with kid gloves. Therefore it is a soft engine and this lack of robustness means it is not as good an engine as, say, a HDI or a DCi which have a tremendous capacity to absorb abusing treament and neglected servicing.
I happen to have have an Almera that's driven hard and has not had an oil change in nearly 3 years and it doesn't complain. Try that with the focus engine and see how far you get.

demanufactured

The 1.6 tdci and 1.6 hdi are one and the same .

TheBoyConor

I'm talking about old Citroen Zantia type HDI

aldub83

Think I’ll go with new filter and take the egr off and have a look while I’m there.
Seems a lot a people do have hate for this engine ha

Before you do anything would you not try read the fault codes and see what is showing.
No point changing parts willy nilly on the chance that it might be the issue and you'll get lucky that you swap the right one.

You clearly have no idea about modern diesel requirements.

Those old petrol almeras are 80's technology, very simple.

TheBoyConor

Excuse me?
Do you want to elaborate?

Could be the alternator. Happened in mine and a common occurance seemingly.

On my Mondeo it's the fuel pump causing exactly the same. High revs as in 2.5 up it dies turn off on no problem till revs go up again.

What I know about modern diesels is that they are unreliable and soft compared to what went before. And specifically designed that way so manufacturers agents can extract the maximum amount of revenue from the customer after the sale of the vehicle by means of extortionatly priced specialist repairs which the dealers have a monopoly on. The whole thing is one big con.

Saw this intermittently in a car before and they never got to the end of it so I am curious to see what the outcome is. Typically happened during the first say 30 minutes of a journey, perhaps coincidence. Car goes into limp mode won't rev over 2500 or 3000 rpm I cant remember. As said turn off the car and on again and it goes fine, no loss of power or limp mode. They Plugged a cheap code reader in and it had an error code (I think for "low boost", could have been P0299 but cannot remember) and cleared it. Anyway it was left into ford for a service a few months later (it had happened between clearing the fault code and leaving it for a service) and they found nothing, no error code they said, said next time it happens to leave it in (okay no problem, can drive it in limp mode to you and leave it running so the engine malfunction light stays on!). As said turning it off and on again (sounds like an I.T. solution) gets rid of the limp mode and drives as normal again.

Google the problems and you will see why.
Injector seals, carbon deposits, blocked mesh in banjo fittings, multiple turbo replacements,

Yeah but not many engines are perfect .type in any engine into google and bad stuff will come up.nobody ever does write ups about engines that never give trouble.its all driving style and luck

Waiting on me plug in back.was just looking for a steer in the right direction

Update. Cleaned egr valve and changed fuel filter.running a bit better but still going into safe mode when you go into high revs.code reader is saying fuel system too lean.was saying blocked fuel as well before filter change.dont remember exact codes

punisher5112

Possible fuel pump as is exactly what mine does.

You need to get this car read by Ford specific scan tool. The exact manufacturer specific codes you need to troubleshoot this are not EOBD codes and are therefore out of reach of a generic scan tool. Diesel engines don't "run lean" like a petrol engine, so clearly the codes your seeing are being misread. Without the correct codes, this will be next to impossible to crack.

As for comments made previously about this engine being soft, they are especially temperamental IF they are not looked after, and by that I mean frequent oil changes using the correct low ash oil. A 2005 Focus with 180,000 miles left our fleet some time back with everything original and I believe has passed the 200K mark since. It was well looked after....

TheBoyConor

+1 on getting the error codes read by someone with a diagnostic kit that covers manufacturer specific codes.

Well thats it, they have to be mollycoddled. The problem is that in the real world, Ireland especially, family cars like this have the same status as a dishwasher - no-one is interested in spending money, time or brainpower on preventative maintenance but rather the begrudgingly do only the absolute bare minimum to pass the NCT, even trying to get worn tyres to pass.

That's why I would not recommend them as a daily workhorse domestic car. Better off getting a car that is robust and hardy enough to tolerate gross neglect of servicing.

Agree completely.
I sold my 08 Focus 1.6 TDCi last year with 406,000km on the clock. Had it for 6 years and minded it.

I had 06 1.6 tdi ford focus, with similar problems. I have replaced many things, no luck, eventually got advice from one my friend mechanic, to check absolutely unrelated thing to power - glow plugs. There was two glow plugs dead. I have replaced all plugs to brand new, and wont believe - car was back to its power.

Maybe worth it have a look on them, if any blown, replace, see if it helps.
