The Duratorq DLD-414 (or DV4) is a 1.4 L (1398 cc) straight-4 turbo-diesel. Output is 68 PS (50 kW; 67 hp) at 4500 rpm and 160 N⋅m (118 lb⋅ft) at 2000 rpm.
The DV4 is available in two versions:
One, a SOHC 8-valve design, uses a KKK KP35 turbocharger but no intercooler. This is the same turbocharger as the Renault K9K Diesel. It is Euro 3 compliant, but will receive a Diesel particulate filter from 2006 to make it Euro 4 compliant. In Ford, Mazda, and most PSA applications it uses a Siemens SID804 or SID802 common rail injection system. The PSA Variant in the 2005-2008 Citroën C1/Peugeot 107/Toyota Aygo 1.4 HDi uses the Siemens SID805 common rail injection system with a lower power output compared to other applications to compensate for the weaker 5-speed manual transmission used in these models. [3] In some PSA applications a Bosch common rail system is used.[citation needed]
A second version uses a DOHC 16-valve design, with an intercooled variable-geometry turbocharger. This engine uses Delphi Corp.'s DCR1400 common-rail injection system. This derivation will no longer be built from 2006, as it will not be able to comply with the EURO4 regulations.

Great that job! That sound when it started up after changing the injector just smacked a smile of satisfaction on my face haha

[@GrubbyRabbitRepairs]

😂 yes it was a great feeling to hear it running so nice! Victories like that make tinkering with cars so much fun! Makes up for all the frustrations of rusty and broken bolts etc! It was great to save it from the scrap heap 🙂. Thanks very much for your comment and sub!

[@garethnoble6699]

I have the same car, 2007 plate. It’s now done 217,000 miles 😅 Had to replace a couple of injectors over the past 7 years but still running sweet 😊

[@GrubbyRabbitRepairs]

It's great to hear that these engines are capable of those mileages 😃. They're worth fixing then and investing in new injectors when they go wrong. Cheap and cheerful motoring really if you can get 200k+ miles out of one, plus only £40 tax and good MPG 🙂

[@garethnoble6699]

Yes great mpg, I get around 70mpg out of mine. As you say, great little cheap run arounds. It’s a shame the injectors are so expensive. Like you I got myself second hand ones. Touch wood they’ve been ok so far!

[@montyludwig]

Good use of the X tool D7 and a thoughtful diagnosis of injector faults on a gifted Fiesta. Hope you get it through the MOT and back on the road. Manky interior is a bit of a challenge even for the Car Cleaning Guru. See his channel.

[@GrubbyRabbitRepairs]

Thanks! I had it booked in for MOT the other day but I found a hole in the exhaust. So I've patched that with a bit of dodgy welding. Hopefully getting it MOT'd next week. I'll check out the Car Cleaning Guru, thanks! 👍

[@munteanuandrei8875]

Keep up, you got a sub from me

[@Nickmedium]

Thanks for your video, similar number 4 on my ford fiesta 1.4 tdci not firing, pulled connection 4 off still runs lumpy put connecter back on, no difference. So 4 needs replacing

[@GrubbyRabbitRepairs]

Thanks very much for your comment 🙂. Weird how number 4 injector seems to be more prone to failing. Maybe it's just coincidence. Good luck getting it sorted anyway!

[@kondaniphiri1278]

Nice Stuff… Which part of the Kingdom are you based or operate from? Have an Avensis that I am facing a similar issue..

[@GrubbyRabbitRepairs]

Thanks! I'm in Lincolnshire, UK. Do you have a code reader to read any fault codes?

[@kondaniphiri1278]

@@GrubbyRabbitRepairs am in Shropshire.. a layman in this field of yours.. had it checked was told Injectors and suspected turbo.. so the garage would not repair 🧑‍🔧 and I am trying, looking and learning from people like you so as to learn more and see way forward.. I can’t just scrap it yet.. I strongly feel and believe there’s still life in it with the right diagnosis and eventually getting it fixed.. fingers crossed 🤞.. if Lincolnshire was close I could definitely have made my way.. keep up the good stuff..

[@GrubbyRabbitRepairs]

@@kondaniphiri1278 Oh yes I think a Toyota could have lots of life left in it. Is it a diesel? If your turbo is accessible you could disconnect the air pipe to the turbo with the engine switched off, then you should be able to put a finger in and see if there is lots of play in the turbo spindle. As for the injectors, read any codes with a code reader. If that doesn't help, as well as the method in this video you could also try a leak off test to see if one injector isn't opening as much as the others. It's a helpful test especially if the engine doesn't fire up so you can't do the 'unplugging' test in this video. You can buy a test kit for £20ish off eBay. Lots of videos on KZbin how to do it. Good luck!

[@adamfarkasbdp]

you didn't have to program the injector in? tell the ECU the values of the new injector?

[@GrubbyRabbitRepairs]

My scan tool didn't have the option to do injector coding on that car. But it runs fine so I'm happy 🙂

[@adamfarkasbdp]

@@GrubbyRabbitRepairs the knocking you have at the end I'm trying to figure out where it's coming from for what I have is twice as loud

I'll have to have another listen next time I start her up. I didn't really notice a knocking sound. Let me know if you find out what's causing yours 👍

[@waltsmith5255]

What make code reader

[@GrubbyRabbitRepairs]

It's an XTool D7. I recommend it for the price/capability

[@eisenschmeisser3959]

disgusting steering wheel... but you did a great job.

😂 thanks! She scrubbed up ok in the end and passed the annual MOT test 😊

[@CharlotteGreen-kv9sx]

I have same problem as my car is a ford fiesta zetec 1.4 tdci 03 plate but it says electric accreltor control fail on dash but my mate put dinostic it saying injector number 4 ?

[@GrubbyRabbitRepairs]

Hi, I'm no expert but I'm wondering if it could be that injector number 4 is not working correctly and is letting too much/too little fuel into the engine and making the car also think that it's got a electronic accelerator control (EAC) fault because it can't control engine fuelling properly. Or there is a chance it is two separate faults. A bit of googling shows EAC faults can be caused by a few things including the accelerator pedal sensor or wiring. Personally I'd go after the injector fault first and see if that gets rid of the EAC issue. You could always just unplug injector number 4 like in this video and see if the EAC fault disappears and you're just left with an injector fault. Where are you located?

[@CharlotteGreen-kv9sx]

@GrubbyRabbitRepairs evening thank you for your reply back to me iam in burnley lands UK 🇬🇧 the car as been like this for 2to3 weeks but I will try that with the wire on the injector were are you please

[@GrubbyRabbitRepairs]

Hi, I'm pretty far away in south Lincolnshire near Bourne. Look at some other videos on how to take the air box off. It's pretty straightforward but there might be 2 bolts on the back of the air box that you can't really see. You have to undo them by feel really. I can't remember if they were for the air box or the rocker cover underneath. Sorry it's been a while since I did this. Not sure if it's something you fancy doing yourself but I got a used injector off eBay for £60ish and a full set of seals (injectors/rocker cover/leak off pipes) for £15ish off eBay. Buying a used injector is a bit of a gamble I guess, but you can buy reconditioned ones for £130ish. New ones are ridiculous and are £200+ each when I checked! I got a great tip for cleaning the injector seat from another video - get a length of 15mm diameter round wooden rod (dowel I think it's called) from a DIY store, then you can wrap a rag round the end to clean the injector seat, then superglue a round piece of fine wet and dry sandpaper to the end to take off any burrs and smooth the seat. When removing the little clips for the leak off pipes, hold them with pliers because they ping off and get lost! Also make sure you cover the top of the engine with rags once you've taken the rocker cover off because you really don't want to be dropping anything down the oil passage ways! Same with the injector ports once you've taken out an injector.

[@CharlotteGreen-kv9sx]

hi mate i know it says Charlotte but iam the husband please can you let us know what number 4 injector is please from the timing belt or gear box thank you ​@GrubbyRabbitRepairs

[@CharlotteGreen-kv9sx]

@@GrubbyRabbitRepairs sorry about this and being a nuisance thank you stu

[@thehutx]

did you have to remove fuel filter

[@GrubbyRabbitRepairs]

No need to remove the fuel filter on this model. I plan to replace it at some point soon though in case that's what caused the injector problem. I'm not sure when it was last done.

[@thehutx]

Just changed 1 of mine now car won't start. Thought it would if fuel filter was not removed

[@GrubbyRabbitRepairs]

@@thehutx You've given it lots of squeezes of the priming bulb? It's a pain having no lift pump in the tank 😬

[@GrubbyRabbitRepairs]

If you're still struggling maybe loosen the fuel pipes to the injectors and squeeze priming bulb until fuel flows from the unions then tighten back up?

[@thehutx]

No left pipes on it
