Ive a 2006 mondeo turbo diesel with an intermittent fault.Driving along the motorway the engine will lose power and the Glowplug light on the dash will start flashing.This has happened 3 times in the past 5 weeks or so.The 3 times its happened,Ive put the car in neutral,turned off the engine and restarted it on the key,popped it back in fifth and drove on.Car is fine then.Looked up the owners handbook,but no mention of glowplug light coming on while driving,only the engine management light,which has never come on during these power losses.Any idea's what is acting up every now and again??Thanks in advance.

 

EGR Valve or injectors

 

its the cam position sensor dude, well known fault on these. Only £16 for a new one from ford and even a window licker like me can change it!

 

if its a tdci chances are it'll need the injectors recoded,
very common prob on these,
pumps can start to break down aswell,
little metal filings clog up the fuel pressure sensor and filter, worth checking these as well,
but chances are its injectors, very very common

 

I think I'd swap a £16 sensor before injectors

But you're right injectors and clutch/dmf are also well known faults.

To remedy this fuck off the Ford and get a german car

 

What engine size is it.

 

the fuel pump is more than likely breaking down and clogging the injectors.at cruising speed the pressure is pushing all the segments to the tips of injectors and clogging them up.when u key off the pressure subsides and they become free again.fault codes you will prob have be p1211 and p0251

 

Get the fault codes read. If they're the ones mentioned above sell the car!!

 

<<<< rubbing hands together lmao.yeah as dan said its a very costly repair as its best to replace injectors,pump and filter inc feed pipes etc.im sure when we price the whole job up it comes to about 2.2k

 

If it's not the CPS it could also be the Inlet Metering Valve on the back of the pump. They can also give the same symptoms.

A pukka Delphi specialist has a kit to test whether the IMV is faulty or not.

 

yeah good point dan.cps normally cuts the car out and normally hard to start.imvs do play up but never replaced one that actually helps the problem lol.

 

There's a couple of people on the Mondeo forums who have discovered it's the cure to their cutting out.

The fuel pressure reg seems to be a suspect at times too!

 

ah cool.will bear that in mind for future probs

 

The problem is that they all seem to throw out the same fault codes, so are hard to pinpoint. At least the FPR is cheap, and the IMV is testable!

 

good point.we sometimes find on the earlier mk3 mondeos that if u take a sample of fuel from filter it may show flakes of metal in it showing lift pump is breaking up

 

 

never said anything about changing the injectors,
just recode them, for me thats 16 quid less than a sensor lol

 

Had the same p1211 and p0251 codes on my mondeo 130PS TDCI.

Fault symptoms were it stalls when cold and major flat spot between 40 - 55 mph causing the glow plug light to come on. Also randomly the engine sounded like an old taxi.

Changed cheap things first - Fuel filter, Cam sensor, crank sensor, fuel pressure sensor, checked all pipes to see if perished, cleaned EGR.

Having injectors recoded at work initially worked for 100 odd miles then car ran crap again due to car adjusting itself during the learning mode(500 miles i think).

In the end took it to a diesel specialist to fault find and one injector was back leaking, the injector was refurbed. Total cost £200 including labour and VAT.

The car ran bad still for 150 miles while the leaning process was taking place but now she runs like an absolute dream.

After alot of forum trawing in the past i would agree with bigchez and change the Cam Sensor first, its £18 from fords, they will give you the latest type as the old one had issues, cant remember which was which, black or grey sensor. Its hard to get the connector off, so unbolt the sensor first then remove connector.

Hope this helps

 

A recode is never a fix, it just delays the inevitable!

 

good point.it puts them back to initial learn parameters and is temp.
early cam sensors are black.later modified ones are grey

 

My Focus TDDI did exactly the same thing when I was on the motorway.
I actually called the AA out and looked a real twat when I turned it over and it started up straight away again.
I think it was the sensor people are talking about, it definitely wasn't injectors and was an easy fix for my local garage. And it never did it again.

 

Lads thanks for all the advice.I'll start with the cam position sensor 1st as its the cheap fix!! Micky

 

my dad had the same problem and we changed a few things inc the glow plugs,
it ended up being the elec boost controler on the turbo, all the teeth were chewed up had to get a new turbo as they dont sell these boxes on there own

 

if its the pump you can get the pump fault diagnosed by a proper diesel specialist and they will tell you exactly what the pump needs - they interrogate the pump directly not thru the comms port in the car

 

You could have taken one from a broken turbo. Despite what Ford tell you they are interchangeable.
