It looks like you're getting closer to finding the fault Martin. It will be interesting to find out exactly what is causing the problem.
Who needs tense TV drama when we have the Mondeo rough running saga.
Yes Nick, It is like a drama and i'm playing the lead role with this vixen hussy Mondeo haha
Hello, I'm from Poland. I like watching your movies are very helpful.
Have you been a lecturer Martin? Your analysis and logic and presentation without notes in front of you is astounding......Well done.
Thanks Col, No bud, just always been into fault finding.
I feel your pain ,AGHHHHH! another great video but this is getting frustrating and its not my car. I think when you finally solve the issue a lot of people will be doing the victory dance just for you Martin.
Haha, I am trying to show in these vids all the things that the people in forums have said is the problem so people can make an informed decision on what their possible problem is as well when I've finished this series. I think i'll do a victory dance anyway lol
great video Martin another step closer to the conclusion of the problem and seeing this video was a great way to end my birthday so i thank you for that its really made my day complete. i look forward to the next video and as always its a big thumbs up from me
Happy birthday Dave, all the best bud.
Cheers
Martin
retrorestore thank you Martin :)
Happy birthday David, all the best to you !
I enjoy these video's too, he is great !
Mark Berry thank you
I bought the same diagnostic tool months ago for a transit problem. Having found a work around to the transit problem I am yet to use the diagnostic kit. Having seen it in action I will be loading up that software.
Being a fix it yourself person just like yourself I feel your frustration. Unfortunately I have no solutions to offer you but your videos have helped by inspiring me to load the software and plug it in. Thank you.
Nice one bud. I'm on the learning curve as well but it's not too hard to work the software.
Cheers
Martin
what software is it? the name
Can't wait for part 6.
It will be tomorrow now Michael as we're enjoying the good weather today and having a BBQ
hi matey I'm feeling your pain but a great learning curve for you buddy Wherever the issue comes back to the electrical issue previously stated try wiggling the wires at the pump see if it improves if not looks like an internal fault somewhere still watching and hoping buddy
I'll be concentrating on that for the next vid Bill. Thanks bud.
Cheers
Martin
thought you had sorted it Martin, oh well look forward to the next vid.cheers steve
So did I Steve.
Cheers
Martin
Gripping stuff this Martin.... much better than the sh@te on telly... you have the patience of a saint mr B.... how you keep from swearing is beyond me !!... keep going m8..
Feel your pain Mart, But an awesome production as always.good luck mate, i have the same mondeo estate with the virtually trouble free 2.0 petrol! lucky me lol.
Cheers Mart, Baz....
Haha, thanks for letting me know Baz lol Only kidding, I do like the Mondeo's, so much room inside compared to todays cars.
hi martin, good stuff now we can get a butchers at the scope results. definitely looks like that voltage is dropping out once its warmed up. the feed to the pump needs checked for a bad ground and or chaffed wires, but remember where they go over the starter is usually where they go kaput although they generally look spot on. a wee tip for you when using the scope is to use longer timebase and you will get a better look at the results and your crank sensor should be showing a 5 volt square wave methinks, and I totally agree this could be a big vacuum leak letting air in causing the overfuelling and leading us all a merry dance, .............waiting for the next installment my friend
cheers willie
Yes, I agree about the time line Willie, i'll have to look into that. Looking for a decent wiring diagram as the Haynes manual doesn't really help.
yep the Haynes manual are crap you could try emanuals online or you will have to scour the internet I'm afraid
I see several have fitted a new lift pump and the problems are gone.
They had the very same fault codes as you.
Nice videos btw ;-)
My mates TDDI suddenly died going up a buzy hill.
Turned out to be the electical wires that goes up to the solinoid had a brakage.
Ford do sell replacement of those wires as it's a common fault.
Kind regards
Richard, Norway :-)
Thanks for the info Richard.
Cheers
Martin
Brilliant video. No one else shows how to find and remove the crankshaft sensor. Only sorry it didn't solve your problem. Thanks
Glad it helped
Have you checked the fuel pressure valve on the fuel pump?.
True about voltages if it's slightly out it could mislead the ecu to reduce fuel.What you want is someone else with a Mondeo TDDI to come along and do tests to see what their voltages and readings are and compare to see what's different on yours and in comparison from a perfect working example to yours in a ideal world obviously lol But all seriousness I hope you can get to the bottom of this without too much expense
Martin great series of vids please when you find the fault do a more in depth series on Forscan it baffles the sh-t ot of me cheers
haha Brian, it did me at first but i'm getting there with it. Not much info out there so I will.
Cheers
Martin
love it
Cheers bud
Slightly off topic , but just check the mass air flow sensor pressure, when these break a default value is sent to the ecu. Just use the reader to make sure the pressure increases when you Rev it. Rules one thing out, some of these items create a knock on effect.
Thanks but, yes it does rise when you rev it.
Cheers
Martin
Hi Martin ,from the symptoms I can see on camera it looks more like a fuel delivery problem than a vacuum problem.
Can your diagnostic give you real time fuel pressure, if so monitor the pressure during the issue.
Also are you sure there is no water in the fuel tank that would give you similar symptoms and might explain the delay in the problem.
Water will sit in the bottom of the tank and as you drive ,if the tank is low on fuel,will intermittently get drawn up causing these symptoms.
Have you tried filling the tank up ?
I'll be changing the lift pump in the next vid so let's hope it could be that.
Cheers
Martin
You're getting there bud.
I hope so, I thought i'd sussed it today lol
Hi Martin, i would be looking at your rail sensor live data and the wiring to it as you may find a broken wire, the only tip i could give and worked for me is get the laptop out of the car and put it beside you and wiggle the wires around the high pressure pump and rail sensor and see if you see any live data drops, spikes. i done this on a HDi and the 3pin to the rail sensor was broken removed it and soldered it and was great after it caused rough running with the wire being broken.this is just a idea but if your like me you would give anything a try lol, good luck Martin for part 6!!
Thanks Craig, this model doesn't have a common rail, it's a direct injection pump. I do suspect a supply voltage problem though.
ah sorry about that I thought there might have been a rail sensor on it, the next one would be the pressure regulator wiring on the pump fingers a crossed its something easy like a broken wire. do you have access to auto data? I think I have it on my laptop I will check to see if it has the wiring schematics and report back.
Thanks Craig, someone's already sent me the diagram and i'm going through it now.
Cheers
Martin
Just use the van. 😂😆👍 good luck Martin.
Haha, I have been Greg lol
Cheers
Martin
Great video Martin, i found this info as i was looking at mondeo fault codes maybe of some use to you.
The TDDi engine has an electronically controlled injection pump, There is a timing solenoid inside the fuel pump that often fails, this normally leaves fault codes P0149 and P1564. The excess smoke and poor running may be when the solenoid has stuck which causes the injection timing to be out.
Also if you feel the car is running out of fuel make sure that the electric fuel pump near the fuel tank is working OK, this pump is only fitted to the 115PS TDDi .
Cheers, Jeff.
you don't need to remove the pump to replace the solenoid, but you will need to remove the inlet manifold for access. You then remove the rear support bracket on the back of the pump, you can then access the two bolts to unbolt the solenoid. If you can't obtain a solenoid from Ford then try a diesel pump repair specialist the pump
Thanks Jeff, I did check the rear pump today and it is working. I'll probably do a smoke test first before I disturb the manifold but it sounds like it could have a solonoid issue.
where is located map sensor for tdi ?
A partially clogged fuel pickup pump, since you said you ran it low, can cause the voltage to drop as it works harder to pick up fuel, should be circa 12v. Initially fuel is in system so it works ok, but once it has to work harder and draw more fuel it all breaks down. Good luck
I'll bear that in mind bud. Thanks
Martin
Hope you get to the bottom of it Martin, what software is that you are using? Does it work with as specific ODB reader. Cheers
It's forscan software and you can download it for free. You just need a cheap obd2 connector from Ebay and your away for Fords.
Thanks Martin think I'll get one as I've got for different models at the moment like Vauxhall and a generic one.
Go placidly amid the noise and the haste, and remember what peace there may be in silence. As far as possible, without surrender, be on good terms with all persons.
Speak your truth quietly and clearly; and listen to others, even to the dull and the ignorant; they too have their story.
Avoid loud and aggressive persons; they are vexatious to the spirit. If you compare yourself with others, you may become vain or bitter, for always there will be greater and lesser persons than yourself.
Enjoy your achievements as well as your plans. Keep interested in your own career, however humble; it is a real possession in the changing fortunes of time.
Exercise caution in your business affairs, for the world is full of trickery. But let this not blind you to what virtue there is; many persons strive for high ideals, and everywhere life is full of heroism.
Be yourself. Especially, do not feign affection. Neither be cynical about love; for in the face of all aridity and disenchantment it is as perennial as the grass.
Take kindly the counsel of the years, gracefully surrendering the things of youth.
Nurture strength of spirit to shield you in sudden misfortune. But do not distress yourself with dark imaginings. Many fears are born of fatigue and loneliness.
Beyond a wholesome discipline, be gentle with yourself. You are a child of the universe no less than the trees and the stars; you have a right to be here.
And whether or not it is clear to you, no doubt the universe is unfolding as it should. Therefore be at peace with God, whatever you conceive Him to be.
And whatever your labors and aspirations, in the noisy confusion of life, keep peace in your soul. With all its sham, drudgery and broken dreams, it is still a beautiful world. Be cheerful. Strive to be happy.
Sounds about right in my eyes :)
hi Martin I posted on a couple of my ford groups for u about the voltage on the fuel pump I keep u posted matey as there not much info on Google about it
Thanks bud, Yes, there's very little, that's why I do these vids.
retrorestore I went and brought the same diagnostic as I was having a problem with my focus 1.8 tdci not reving over 2000 rpm and my problem was map sencer the live data is a great peace of kit matey thank you for doing the vids matey keep up the good work you r the reason I started to do my own vids
Thanks for finding the diagram bud, it's a great help.
Feel your frustration Martin.
Most garages would just plug n play...which would cost a fortune, if they didn't drop on it quickly.
Still hoping it's something simple...and not too expensive.!!!
Yes, if I took it to a garage, i'd be looking at £1,000 + so i'll take my chances. Graham.
Cheers
Martin
retrorestore
so would I.....😉
Martin.... just a thought .... could it be something disturbed when you replaced the clutch recently??
It's been running too well as that was done over a year ago Rob.
Cheers
Martin
OK Martin, try this. With the car running, wiggle the plug at the fuel pump, then the ECU plug, then the fuel pump relay, one at a time to see if the fault would happen while looking at the data list. If all ok, check the earth is tight and clean coming out of the fuel pump (my be hard to find, but if you can follow the black wire back). If OK then do this, as you can see that it is loosing it's 12v reference from the data list, tap into (back pin) the 12v reference that comes from the relay to pin 7 at the fuel pump ecu with a multi meter and check for 12v (it is constant 12v) while looking at the data list when the fault happens, so if you get the fault up, and the data list say's 1v, but the multi meter is ready 12v then the fuel pump ECU is at fault.
Liam Goodger it's the supply voltage to the pump am on about, not the crank shaft sensor.
Sounds logical, I have the wiring diagrams now but I have one more thing to do in the next vid.
hi mte so sorry to bother you im gonn tackle dmf on mk 2.5 focus 1.6 tdci today and i woundered your thought on single mass convertion as its more than half price of dmf kitt ny help would be really greatfull
You'll hear people say that it's worthwhile doing and others say that it failed shortly after again. To my way of thinking, They would not have designed it if it wasn't needed. Not only that, pattern parts are normally not as good quality as OE parts so taking this into consideration, I fitted a Pattern DMF like the standard one. At least It was cheaper than OE parts and I didn't risk it failing.
Just my opinion.
cheers pal value your opinion u obviously no your shit
ey up buddy just managed to get box off that focus and someone already done single mass convertion so u was right it didnt last long ive just found paperwork out and it was done 28k miles ago so deffo going dmf cheers boss u the man
Hi mate can you do a video on what to do when your bonnet is lock and cant open it because I do have that problem now unfortunately 😐
We don't have the car any more, sorry.
@@retrorestore thanks for reply so you dont have that car anymore and can i ask you what do you think about those cars are they good? Or not? Because I just bought one recently
Lift the grill up, just standing in some grooves in the bumper.
From the key lock, there is a plastic pipe/rod going to the lock mechanisn. This breaks sometimes. But should be able to twist the lock itself from under the grill with a set of vice grips or something.
Ford Mondeo TTDi SCI (get a custom CSI sticker after its fixed - with a Sherlock magnifying glass):)
Haha, sounds like a good idea lol
Try using forscan in dashboard mode instead of scope, then you will be able to see physical numbers, and you will be able to see if your fuel pressure is to high or low.
Yes, I've been doing that as well but not shown it in the vid.
Cheers
Martin
I'm not 100% on Tddi but fuel pressure at idle should around 250bar, when revved 750bar, and upto 1600bar under load as a guide, like I say not 100% on Tddi.Cant remember if forscan reads in Kpa but if it does 100Kpa= 1Bar. HTH.Be interesting to see what the pressure is when under power loss.
Nice one, I'll check that out too.
Cheers
Martin
Where is the camshaft sensor in that car? it's a mystery... (camshaft)
What sort of code reader are you using?
We have a Topdon now.
Awww CRAP!! I coulda sworn it was the crank sensor. The low voltage might be a request as too much pressure at Injectors? On and off with the pump as pressure is required? I dont know, just guessing. Intermittent ground?
I thought that too Bri, Can't find a decent wiring diagram so gotta start there.
HI I STILL THINK ITS THE PUMP IN THE TANK OR A O2 SENSER MATE
No pump in the tank Nick and no O2 sensor.
Great vid mate.have sent you a different view of the wiring diagram
Cheers
Jamie
Thanks Jamie, i'll check it out.
Cheers
Martin
check egr valve,if it is gone and It remains an open or closed position,make same problems
EGR Valve was checked in an earlier vid bud.
do you stil have Ford Mondeo 1.8 16, I think I have the same EGR valves, simply swap them for sample If your stuck in the open position, scoring more exhaust gas into the air system, so the pump can not deliver as much fuel, and therefore gives errors and pulling
No I don't but this egr valve is not stuck open.
Cheers
Martin
So close Martin . Sure your nail it .
It's a frustrating one Pete as I don't have all the info of how the sensors interact with the ecu and the pump.
As you have cleared the other codes its close . I take it the relay is for the main injection pump .
Bloody Nora the saga continues lol , you must get there soon mate you should get some gloves or Mrs B is gonna be giving you a rollicking dirty paw prints on her gear knob and steering wheel 😂
Haha Paul, I'll have to clean the old knob before she goes anywhere near it lol
Hahahahaha that is all, you do make me laugh Martin :)
retrorestore 😂😂😂😂😂👍👍
When its kangarooing its like somebody has put the wrong fuel in the tank.
P1564 looks like it's the diesel pump.www.ecutesting.com/catalogue/product/ford_transit_diesel_pump_edc_edc041018-a.html
This isn't a no start as that suggests with the other codes. although people with the same 3 codes as me have fitted a new lift pump to cure the problem so I've just got one of those.
first
Its being French.
Yeah rubbish electrics. 2 Clio's was enough for me.
I mended mine by buying another car
