ford focus 1.6 tdci cutting out problem
Ive had the focus since september 2011, 1.6 tdci zetec climate 2006 .
the first week i had it , i was driving down m6 and it died engine management light came on , i got the codes read and it was turbo overboost condition, crankshaft sensor and dpf problem, i took it back to the dealers i got it from and they hed it for 2 hours said they run a clearner through car and all is ok. The car has been fine ever since till mid Feburary then it started to not start first time , i had the codes read and the same faults came up ! gradually its got worst. Then it developed a new symptom juddering , one violent jolt, then even harder to start , called out the breakdown people before i joined rac and they read mass air flow sensor, changed this at £110 and it drove fine for one day , but then on sunday it shuddered and died engine system fault came up but no engine management light, the next day i picked it up from where i parked it and it was ok untill it got a bit warm then it was like a kangaroo with engine system fault coming up no engine management light was present, i revved it by balancing clutch and it drove ok home but cut out at traffic lights its seems to idle bad and wants to stall,
help im at a loss and can not afford fords prices as ive recently been laid off.
thanks in advance
To get a true diagnosis it needs to be read by a garage with good equipment. That does not mean Ford. A lot of mobile mechanics have the equipment for this as do local garages but you need to ask them first.
The engine system fault without the engine management light can be read with very good quality scanners only. I would guess that the original problem has returned.and that the turbo, EGR valve and the DPF are all choked up with soot. The cleaner was only ever going to be a temporary fix. The car needs to be checked for sooting up of the exhaust gas recirculation valve (EGR) then on a proper diagnostic tool, a forced regeneration should be carried out. This process removes the soot from the diesel particulate filter (DPF). It takes around 10-20 mins.
The crankshaft sensor and mass airflow sensor would not have been faulty, they are just symptoms of the coked up engine.
Once cleaned out and sorted, it is absolutely vital you understand that you must drive the car once a week for at least 20 mins at a speed greater than 50mph so a motorway thrash is ideal. If you do not then it will coke up again.
hi hometune ,
thanks for your quick response,
at what sort of cost do you think is this going to be , and do you think that the garage i got it from is in any way responable for this as its the faults it took it back with, this car has got a full ford service history and the dpf was changed in november 2010. would it soot up so quick , i take it on motorway at least once a month , is this not enough ?
The selling garage is liable for 6 months. If a repair is carried out then that repair should be 12 months. The problem may be that you have been to a second garage so the first will use this as a cop-out. You should be able to get a forced regeneration done for under £100 but depending on the level of soot in the other components, it is hard to say.
The DPF should not need changing if the driving advice is followed so the fact it has been done already means too many short journeys. They soot up within weeks if not driven hard. As said previously, it is absolutely essential you understand this problem. Once a month is not nearly enough if all your journeys are shopping trips, school runs, stop start deliveries or sitting in traffic. DPFs are very expensive so a good drive once a week at 70mph down the motorway for 10 miles and back is much cheaper.
There have been other posts by drivers with DPFs problems and they are always trouble, not just Fords.
My advice would be to find a diesel specialist garage who do this type of work every day.
Remember, I am only guessing at the fault from the info written here so the fault may be something else.
