Worst Diesel Fuel Injector I Have Ever Seen Leak Off Ford Mondeo Mk5 2L

[@markhart3432]

"Absolutely bollucks'd" 😆 love the technical references

[@alan4x]

lol

[@TRC98]

My #1 injector basically disintegrated on the motorway and stranded me. Never seen a static leak-off fail so spectacularly

[@robbob2861]

Thx for the video. Please make a video on how do you connect the testing equipment for injector leaking and how do you change a leaking fuel injector with coding. Or maybe you have already?

[@alan4x]

at the end of this video where the more vids appear there is a vid that should be more about the leak off test and i think replacing an injector

[@benevans3733]

Hi Alan congratulations on reaching 31,600 subscribers and you will soon be at 32,000 subscribers and well done for all your continued hard work as always

[@alan4x]

thanks ben, hope you are well and doing good

[@cubleycat]

Very interesting to hear about what can happen if you don’t code the injectors in, I just bought a MK4 UFBA and it has that pincking noise only on acceleration. I will have to check all the injectors are coded because I think someone has been playing with the injectors! I love your videos by the way, great sense of humour 🙂

[@brigman28]

Nice too see you on the video's Allan.👍

Interesting on the same injectors i had a Huntingdon taxi on the storm day from Huntingdon to London due to a garden shed , & a trampoline on the railway line . It was a Vauxhall minibus , the driver told me they took a Mondeo to two Ford dealers one locally & the other in Sheffield. Ended up with two large bills. The fault returned , he contacted you sorted it in minutes , a faulty injector . I can not remember the name of the company .

[@alan4x]

must have been a while back, had quite a few customers in for injectors, cheers mark

[@DavidB-rx3km]

The code on the top of the injector is the code for the flow rate it has been manufactured to. There are very minute differences probably, but the big pressures of diesel injectors might be obvious when running the engine.

[@martinhardy3932]

The coding allows for individual unit correction of injection quantity vs energisation pulse width and also it also compensates the timing of the injection. This is required to accommodate the manufacturing tolerances of the injector nozzle flow rate but also for part-to-part variations in the control valve performance. Without entering the correct code the most obvious fault would be a timing error ('pinking') , rough idle and generally poor cylinder balance.

[@johnbennett4796]

well explained so anybody can understand and no high tec bullshit

[@TheUltimate65]

To take the test , its the temperature of the engine cold, hallf varm, or nomale drive temperature

[@benevans3733]

How is the taxi business going now as restrictions are starting to end

[@alan4x]

its all getting back to normal slowly

[@malcelwell7209]

Great video Alan

[@alan4x]

thanks malc

[@phillmcaverty]

Had one hooked up looking for a bad injector. Put the radio on and it filled a bottle. Injector was stuck open

[@zeb3144]

Atleast we can see your not running the fleet on dodgy cooking oil!

[@alan4x]

lol

[@0067jon]

Had the p2000 code pop up randomly every so often for over 70,000 miles on my 2015 2.0 tdci. Sometimes it brought the engine management light on but mostly it didn't. The car ran fine and I was never able to find the issue causing it. Would be interested to know if you've rectified the fault causing the code on any of your Mondeo's. Was it related to the leak off issue primarily that you have described.

[@alan4x]

i believe that code is a software issue that can be rectified at a ford dealer but it is so random that we just clear it and not worry

[@RobertBosch9397]

It looks like you connected the high-pressure side for the leak test at nr 4🤣🤣🤣🤣🤣🤣

[@alan4x]

lol

[@razvanturcu9871]

Just two questions: 1. Are those piezo injectors? 2. If we test piezo injectors with this kit, isn't there the risk for them to break? (I heared from a guy in Africa that he disconnected a fuel return pipe at a BMW with bosch piezo injectors, and broke the injector this way).

[@cosminronea4688]

My bloody 2.0tdci S-max with 160k after driving 10miles puts out a greyish cloud of smoke for 5 second, not when starting,not after that. Because I drive the same way every day I only need to see the mark on the road and I know that is time to look for the smoke 🤣. Of course no errors, starts perfect and runs good. Is really pissing me off 🙈

[@marke293]

Yet another great Video Alan> I have a question for you about these engine's what would cause soot build up on the injector tip ? I took allthe injectors out of my car cleaned them and after just 45 miles the tip are covered in soot again ? The engine is the 2.0 but in a peugeot Thanks M4rke

[@Galaxy.865]

Great video as usual Alan 👌 I have a question when you connect the leak of pipe did you take off fuel pump fuse. Is Hard to finde that

[@richardbirks7217]

Hi buddy I have a similar issue with my x5 30d under hard acceleration goes into limp mode and comes up low pressure issue changed hpfp and still same hopefully it's an injector will try this today

[@alan4x]

it could well be, good luck

[@jothain]

Wow, I don't know much about diesels, but I've always thought that so badly leaking injector wouldn't even start engine anymore. I though that you'd have start engine with pilot spray if leaking is that bad.

[@alan4x]

not had an engine that would not start due to badly leaking off injectors but certainly a few that cranked over a fair bit before they started

[@jothain]

@@alan4x Thank for correcting my assumption. I don’t actually know where I’ve gotten the idea. I think I’ve just thought that pump couldn’t create enough pressure during cranking to start. Though I guess I’ve been somewhat on point if it indeed still effects starting.

[@Kiwi-es5le]

Hi Alan, my 2.0 duratorq mk4 goes into limp and sometimes shuts down (battery and oil light) while driving around 2000rpm. Won’t do it on light throttle or idle, there’s always air bubbles in the supply line to the pump but I can rev it to 3500 in idle no dramas n starts every time. Code iv got is P1169 high pressure in range Small leak and large leak codes were set also, Wud you recommend do a leak off test for blocked injectors or perhaps it’s a fuel leak causing my car to limp n shut down? Not sure if there’s a leak in my fuel lines or housings, I can’t get bubbles out no matter how many times I suck fuel thru manually and I have replaced the fuel filter and Oring seal and all looks sealed. I have an air compressor might blow air thru the lines to check for leaks You know a lot about these cars I’d appreciate it if you can offer some advice Cheers Alan

[@alan4x]

hi kiwi, there is a very high chance you have one or more of your fuel injectors leaking too much fuel off to the tank causing low pressure in your fuel rail which is why you get limp mode when you put your foot down, so I would do a leak off test and replace the faulty injectors and also replace the leak off pipes which can suck in air when the seals get old

[@Robdoesguitar]

I did a leak of test on my 2.0dci Renault M9r and all four were that bad, not joking 😳 it's still runs fine, doesn't like starting when left or cold but once started it's fine..

[@andyhodgev.a.g1291]

Hi chaps and Alan, love your videos, does anybody know where ad blue fill cap is on Ford S max Vignale 2018, this car has spare wheel.

[@Londonsfinest318]

I’ve got a 2012 insignia, car only goes into limp mode during a DPF regen. Get code p0087 low fuel pressure. It’ll be fine all week until Dpf regen time and it’ll throw a wobbly. Replaced filter, pressure regulator and coded it. Recon it could be a bad Injector?

[@gs425]

Hi Alan. I get a pinking type sound on my ml4 2l tdci 140. However I live on a steep hill, and I only really get it on overrun coming down the hill...circa 2000rpm 2nd gear. I bought it at 125k and its done 185k now and not got worse, but the tappety sound is quite noticeable. Any ideas? Are there any flaps in the intake manifold that flap about perhaps?

[@andyc3856]

Yay,Mondeo content 😂

[@engineer_josh1111]

Hi mate had the same on my bmw 320d one was leaking back too much , same thing 6th gear boot and would go into limp mode , changed one injector but which leaked about the same rate but changed one and run the car up was fine for a short time to find the fuel pump was running all the time and then it fount the next weakest I believe which then was leaking off just as fast , cars on 175k and just brought a full set of reconditioned injectors so hopefully that sorts the issue ? Fuel pumps always humming atm so hopefully this resolves the issue when I fit them

[@andrewjames7616]

Thankyou allen 👍

I have 2 that return at same volume and 2 that dont return anything. Which one's have failed.

[@DJEvoIX]

and how to repair it at home? some cleaninig or?

[@mkasmr5444]

Hi matey, having this problem with my 2.0 Citroen dispatch (which is the same engine) when I accelerate hard in 4th , 5th gear it pulls back like your describing but with no engine management light on but the glow plug light with flash for a quick second then it’s okay. Recently getting worse but would you say that’ll be an injector?

[@bmwe4669]

Hi Alan, 2 injectors gone on my 2016 2.0tdci (180) do you think it's worth to go for all 4 new? And would you go for refurbished ones or brand new ones? Cheers Artur.

[@alan4x]

it all depends how much you want to spend, i normally just replace the faulty ones, euro car parts sell new genuine injectors a bit less than than ford would but if if came to it i would buy genuine injectors, have had too many problems with refurbished ones in the past

[@bmwe4669]

@@alan4x Thanks a lot , much appreciated 👍

[@leer9951]

Blimey, that’s pretty conclusive. What’s the mileage?

[@alan4x]

its 213k miles

[@Nick-dp7ti]

So I did this test on my e46 330d last night after the DDE light came on, diagnostic also says low fuel rail pressure. All 6 injectors filled up almost as fast as that one! 50 seconds gave me between 40 and 60ml in each. I take it they all need replacing?

[@gmoney9588]

Hello Alan ! Wow , talk about a rich condition , that is almost scary . Not sure whether a hydrolock condition can come from that but it’s certainly not normal and very extreme , to say the least . Diesel fuel is a better lubricant than gasoline ( petrol ) but I really don’t think it’s welcome at that rate in a combustion chamber . I’ve never worked on electronic diesel injection , know just basics if that of them , but I’ll say that is a condition that was caught in a nick of time . If it weren’t for computer diagnostics setting a DTC , only a trained ear would catch that I would think . Lord knows if the hired drivers would care or not but I’m guessing a vehicle condition report will be filled out and fuel consumption report would catch it as well if it weren’t for the check engine light . Last time I had my hands on any Diesel engine ,,and I wasn’t a diesel mechanic , was in my late teens working in a salvage yard . Never on the trucks ( lorries ) but the pay loaders as general maintenance . We weren’t allowed to wrench on them , they called in the Pro’s on them . If ever diesels catch on here in the US ( doubtful ) , I’ll have a bit more of a clue from watching your channel . Although I’m to some degree more petrol engine experienced , I wouldn’t mind of diesels came in our cars . The fuel prices will never allow that nowadays though . Yeah , let’s go Brandon . Nice one corn pop joe . He’s worn out his welcome in the UK , I’d imagine . Well , thank you sir for another lesson . Always welcome !

you don't need connectors on the 2l diesel engine...just push the washer pipes into the injector leak off pipe hole in the injector

[@khalidacosta7133]

Modern petrols are just as bad with high pressure fuel pumps and injectors. Newest petrols have particulate filters too. Only reason you see diesels fail more is because people only buy a diesel to do a lot of miles in, so driven more, they'll generally have faults more often.

[@jhsevs]

Is this a Renault engine?

[@Robdoesguitar]

Peugeot/ Citroen/ PSA I believe

Good old Bosch injectors , modern day diesels are shite Alan as we know , so expensive to fix nowadays 👍👍

[@jothain]

Well it depends. I have now driven plus 600tkm's with my 2l diesel Mondeo mk4. To my knowledge it even has original turbo. Stuff I've replaced in about 150tkm's has been egr valve. That's it. I'd say that's quite well for modern diesel. Sure, I'm not expecting it to last for long anymore, but I don't care. Car doesn't have any value at all anymore anyway I'll just drive it until it dies.

i certainly go through enough injectors but there is a fleet of about 100 mondeos lol
