TDCi Focus cutting out - isettaman
Hi
A problem has just started with my TDCi Focus today, twice it has just cut out, no misfire or hesitation, a complete stop. Having rolled to a "safe" stop so far, the engine has then started fine straightaway.
A friend has told me to check the fuel filter for contaminants as my fist step, is that correct? I thought that contaminated fuel would produce misfiring etc?

What are your thoughts?

Dave

Hi welcome to the BR, contrary to my e-mail to you going to leave this as a stand alone thread, but I've linked the Focus thread recommended by Cheddar a thread covering similar problems, a very useful read for anyone with a similar problem. post replies on here by all means...PU

PU,

I dont think the Mondeo threads are at all relevant though this recent Focus one could well be, basically the same subject line:

When reading your post; why do the words "cam sensor" come to mind.....?

Have you had the fault-codes read yet?

Hi Screwloose
I took it to my regular garage but they couldn't get into the system.
Have booked it into the main dealer (friday earliest) for a diagnostic which will cost me £70odd plus vat!

After reading all the threads, my visit to the main dealer fills me with dread!

Can anyone reccomend a GOOD place to take my car near to Wakefield?

Cheers

No ideas re Wakefield though the main dealer is a good starting point, there are some bad dealers and many good ones, diagnostics should be about £50 plus vat, the plug it in and run through everything, all being weel a fault code should highlight a clear issue such as a rail pressure sensor, if however they say you need new injectors, or a new high pressure pump, say you will think about it and post back here, it might be wise to get a second opinion and a diesel specialist would be more cost effective if that kind of work is required.

How old is the car, when did the warranty expire?

One thing I would do is to take and keep a sample of fuel from the fuel filter before you take the car in.

If there's any trouble about fuel contamination, you have a sample which you can get analysed to support your case. Without a sample, it's your word against theirs.

Thanks for that, number-cruncher.

I'm no stranger to machanics having restored a Triumph speed twin, Isetta and gery fergi tractor but, stupidly enough, I cannot sus how to get the top cover off the engine. I've undone the two nuts but there's another cunning fastening underneath which I can't sort out - don't want to break anything!

Sorry, when I wrote the post, I didn't realise you were out of warranty - therefore, my suggestion isn't of great relevance to you.

Fuel contamination is a typical ruse that can be used to avoid making a full warranty repair - which can be quite an expensive task. I suggested taking a sample, because it's extremely cheap to do, and might strengthen your case in an argument.

It's 03 and covered 80,000 mls so well out of warranty.
Thanks for your suggestions.

I wonder if issues are being mixed here, contaminated fuel could cause the car to cut out, however contaminated fuel can also damage the high pressure injection pump though a damaged pump would offer different symptoms.

"would" or "could", I would say ......... most likely offer different symptoms

With a damaged pump it is unlikely to cut out suddenly then start again and be fine until the next time it cuts out.
TDCi Focus cutting out - Number_Cruncher
>>unlikely to cut out suddenly

These systems have a pressure transducer on the common rail. If the pressure drops, the system is stopped - suddenly. If you have contamination which is holding a valve open in the pump, it can easily be washed aside when you start up again. Other faults may be more likely, but, we can't really rule much out when doing diagnosis via internet! The advice to collect a small sample of fuel would have cost the OP nothing but an old clean jam jar.

Of course, the issue of fuel contamination affecting who pays for this work is irrelevant as this isn't warranty work.

I agree that the right course of action is to check the codes, and, knowing Screwloose's previous posts, I expect he's right.

>>pressure transducer on the common rail>>

And on the Focus these have been known to be the cause of the trouble.

Agree re fuel sample, sensible to do.

Just off to get some fresh fuel to top up the filter after removing it.

Just when I thought it wouldn't happen again (only cut out twice last Friday and not since), it cut out this afternoon but this time wouldn't restart for about 10 mins. I'm not going to trust it again until it's been to the main dealer on Friday.

Dave
TDCi Focus cutting out - isettaman
Screwloose you are correct!

Just had a call from the main dealer, diagnostic has found a faulty cam sensor - cost £90 plus VAT including the diagnostic which I don't think is too bad.
Only unfortunate thing is they haven't one in stock so I'll be relying on the boss's car this weekend.

Cheers

Glad to hear they're on the ball. Call it an inspired guess...

£90 is very reasonable - if they've no stock; tell them to do what most dealer's do and nick one out of a new car in the showroom! [That'll have the latest type and they can mod your plug with the fit-kit.]

The way the Footsie's going; they won't have any buyers this weekend anyway, so nobody'll notice.

Back on the road, £95.16 all in, including the diagnostic, cam sensor and fitting.

Seems to be running sweeter now but this could just be my imagination or the comparison to my better half's Rover 25 I've been using.

Many thanks for all your helpful comments.
