Please be careful. I absolutely don't want to discourage anybody from fixing their own stuff, but I own an engine machine shop and I rebuild engines for a living. I have to fix quite a few engines their owners destroyed with home-built injectors. If you have an ancient cast iron boat anchor, you can get away with a hobby botch job. But when it comes to direct injection high performance engines you will melt your pistons in a blink of an eye if you mix up shims or plungers or if you install collars backwards.
If your copper washers get stuck down the bore I welded a thin stud extractor onto a thin extension and it came out immediately after hours of scratching my head. Very useful video. Thanks.

Soaking in solvent overnight cleans the internal parts. The tip and screw cap will hardly be touched. A strong solution of caustic soda (lye) NaOH will burn out carbon but won't touch steel. It will dissolve aluminium, zinc etc (bad for brass) but these are not present in the nozzle area.

One tip from a guy who's job it is to actually recondition these injectors...please don't put loctite on the nozzle threads! When I inevitably get your injectors to properly rebuild, it sure makes it a lot easier when the nut comes off.
Because of this video I started cleaning injectors really a clear video this is how to take everything apart and luckily earn good money with it!!! still looking into revision where I can find parts so far never had any complaints and no I'm not a garage I just do this at home as at work Thank you for the video
Great video. Interesting that these are from a Hyundai and use a shim. My 2014 328d BMW has what looks like a larger spring and no shims. I just cleaned mine because I got a fault code for my #3 injector. BMW ISTA says throw away and replace with new injector! Well, after cleaning all 4 injectors nozzles, swapping #3 & #4 injector cylinders, reprogramming the computer, and clearing the codes, the fault has not come back and the car runs great. This is definitely a great practice to add to your maintenance schedule. I'm just wondering why my original injectors lasted 130,000 miles ( and failed due to a bad CP4 high pressure fuel pump) while my Bosch replacements got clogged after 1 year of service? Bad fuel? Hotshots additive? Towing 3,000 pounds of wood flooring?
Carefully examine the injector seats pithing the the cylinder head and recut the surface if necessary. Extracting a stuck injector (caused by gas blowing past the copper washer) can be a real struggle.
@@paterix79 car is running perfect now, I only clean the injectors externally, didn’t pull them apart as can’t get the recalibrated where I live, all the copper washers replaced, o rings too and used new stretch bolts, car is purring now
Hi ! My 207 which has 400,000 km and which still has its 4 original injectors, I will do to it what you did (except that I will also unscrew the upper part in order to immerse the injector completely (electrical part removed). I I think they will get a new lease of life. Then I will do the same thing with my original turbo. Thanks for your video! :)
Awesome video! I can't do it because my 3.0 TDI is Piezo and I don't have the shop ability to vacuum the air out. My only suggestion is to put the information in the notes that an alloy safe engine degreaser is ok for the sonic cleaner. I used one of the aluminum safe purple power cleaners for car parts.
This is just too good. I have problem with injectors, after i press gas pedal little bit further engine start shaking and almost turning off. When i connect diagnostic i see that 3injectors parameters are going crazy like 4.5-5mg and normal is like 0-1.5mg+/-. I cleaned injectors like this and now car is working perfectly, on diagnostic it shows 0.1-0.2mg.
Great tutorial!👌🏻 after I did this on my Volvo v50 2.0D (Siemens injectors) sometimes it feels like the engine is running on 3 cylinders or an imbalance around 1000 rpm You can feel the power increase and it’s running smoother! No horse powers lost but still got this problem:(
@@daniellenner813 Siemens / Continental injectors have a very small gap set between the injector solenoid and body, this gap is measured in micrometers, for your injector it is 0.3µm ± 1.3µm. You should never take off the soloenoid from a continental injector unless you have tools to measure this gap (I use an Opensystems Megatester V4). As for opening the nozzle side, you will change how the injector works ever so slightly meaning your calibration code will no longer be valid, however sometimes you can get away with this depending on how worn everything is.
Awesome man! And that is probably the best instructional video I’ve seen on any topic! And I have the confidence now to tackle it. Thank you very much!
Great Work mate. I've been told it's not good for the ultrasonic cleaner for items to be touching the bottom of the tank. That's why they come with a basket.
Dishwasher powder. You can buy special injector cleaning solution for 60 bucks a quart, but according to the safety datasheet that stuff is just caustic soda and detergent. Exactly the same as dishwasher powder. Just be sure to rinse the injectors directly after cleaning them and put them in a cup of diesel fuel immediately. If you don't do that, they will develop surface rust in just a few minutes and then they are basically trash.
Excellent tuto. Many thanks 👍👍👌👌. Now ready to do the same with my injectors (and then, as David Elliot said, recut the surface of one seat as heath and flashes passed the copper ring 🥴🥴). Tribute to BTD.
Great help. I'm going to try do the same. But I only have car cleaner instead of the sonic cleaning. Would it be helpful if I unscrew the top part off as well to flush the car spray in there too?
If i want to change the nozzle, do i have to adjust it new with adjust washer? Want to upgrade a stock om611 injector with nozzles from a C30AMG. Same injector, other nozzle. Thanks! :)
Short answer: yes... Not all nozzles are built identical, that's why those shims exist... If you do this yourself you can experience a rough idle... But it can be done, the injection angle should be the same...
Hi boss,I have to say a mega video one of the best on the subject of general overhaul of mag-controlled injectors. My question is which threadlocker (medium strength / high strength / heat resistance) do you use? The usual products are resistant up to 300 degrees Celsius - because the temperatures in the combustion chamber are around 900 degrees Celsius! I would be very pleased to receive an answer ... Many greetings
While the combustion chamber temperatures are 900C, the walls of the cylinder aren't that hot, and things further back are even cooler as coolant channels run by them. I'd say 300C sounds a little low for an engine, but it's probably fine, or rather, if your injectors are 300C then you probably have bigger problems than the type of lock-tite you used, that's really really hot.
Absolutely good performing ! ! ! At what values of the injectors should we start to worry? My one is Audi A6 C7 3.0 dti 204 HP and one of the Injector reading is 0.70 mg . 1 Cyl - 0.7 2 Cyl -0.33 3- cyl 0.13 4 Cyl -0.30 5 Cyl -0.4 6 Cyl -0.10 Mg . Do I have to remove the number 1 injector for cleaning or is there a chance it can be cleaned with a carbon cleaner
Hi Fella I will be using your video as a tutorial. Seems I have a few merc black deaths to do after I did a merc C200 for a friend, Seems his friends are needing the same work done. However I am 75, And as I did the job for a friend I am unable to find a price that I can charge them for doing the nasty job. A lot of lads on utube do the work but never say how much it costs. cheers a nice video and well presented too. bye.
Bello il video complimenti per la spiegazione ma una domanda dopo che sono stati puliti iniettori sono Pronto a mettere apposto o bisogna fare qualche regolazione così ho sentito grazie sei rispondi
I have a question my needle doesn't want to go back. During disassembly it came out very easy now it seize right at the begining. I put the head back for another 30 minutes of ultrasonic cleaning hoping that there is a small dirt. But still doesn't go in. Would it be a problem if I force it? Does this need to be moving once it's assembled ?
GREAT GREAT VIDEO!!!!! Probably the best on You Tube! Not doubting you, but what is your source for the 50 ft lbs torque to reinstall the nozzle to base injector? thx much!
Should the injector body not be cleaned as well? Should this resolve noisy injectors on a toyota 1kd engine? Mine sounds like it has a massive diesel knock while driving, 200000km
If you install the tips in the injector bodies they came out of and if you don't mix up the shims in two stage injectors you will be fine. If you mix up the shims for the pilot and main spring, you are fckd, though. Be careful.
Please your information - what minimum power in Watts and frequency in kHz must an ultrasonic cleaner have to reliably clean the injection valves, nozzles ? Thank you for your answer in advance.
If you have had a catastrophic HPFP failure on a vw 3.0L CATA 2011 Touareg are the injectors salvageable? Can I clean them and reuse them or are they scarp? Do the aluminum particles from the HPFP do damage to the injectors that can't be fixed?
It depends on how long you were still running the engine after the HPFP was shot. Try to check the fuel rail and pipes first for debris. If you find any, it’s best to bring the injectors to a professional who can fully take it apart and run it on a bench test machine.
I love the video, that's exactly what I was looking for. thank you for such all around beautiful video. Questions: what kind of ultrasonic liquid did you use? where can I find the torque specs for my Bosch injector? TIA
Hi, great video very detailed and clear, would this process work with a 1.6 Tdi Fuel Injector Unit 03L130277S made by Continental. These new are approx. £450, so would love to be able to clean my old injectors if possible. Any help and advice would be most appreciated thank you
Really well instructed video, what type of ultrasonic cleaner machine do you use and what solution do you use for cleaning. Thanks Ash from Scotland 🏴
Hi! Got the tank from ebay. Says it has 50w u/s power, 40khz frequency and a 100w heating power at the back. Not sure if it’s really accurate though. Regarding the ultrasonic solution, it’s a custom mix we get from a local supplier here in ph. You can find a lot of them online, just get the ones that are aluminum safe. Thanks for watching :)
If you rinse and oil the parts IMMEDIATELY after taking them out of the cleaner, dishwasher powder in about 60 degrees C water works incredibly well. But you really have to rinse and oil the parts immediately after taking them out of the bath. They will develop surface rust in mere minutes and then they are destroyed.
Will it help if my turbodiesel smokes black on acceleration? Everything else is checked. The mileage is 265.000 km and I believe the injectors were never out of the engine.
Yes it might. If not, best to have them tested at a reputable shop. You might also want to check your turbo and air intake system since you’re getting black smoke, you might be running rich, too much fuel, lack of air.
Hi Paul! Not really but it wouldn’t hurt to pour some diesel in the holes while it’s upside down then quickly turning it upright to let it drain. Carbon buildup usually takes place in the nozzles. In some cases though where the injectors get contaminated by water or particles from dirty diesel, the injectors will require a complete tear down/reconditioning but it’s best to let a professional do it.
Basically, all injector calibration codes are inputted in the ECU from the factory. These codes help the ECU determine the specific output flow of each injector as no injector is exactly identical. Now, wear and tear or repairs such as replacing some injector internals with bnew ones will give a different output than the programmed data in the ECU. This scenario requires a special machine such as Hartridge Injector Calibrators to generate new calibration codes for each injector then you can input these codes in the ECU using a scantool with an Injector Coding function. If you just cleaned the internals like we did in this video and didn't notice any loss of power and high fuel consumption afterwards then you're fine. But if you did, It's best to bring your unit to a calibration shop that can test/read and generate new calibration codes for your injector.
@@btdgarage Hi, thanks for very detailed explanation!!! it is very clear now!! another question and last one is if is necessary to ANNEAL the washers under the injectors before mounting or not? Thanks again :-)
I worked in a factory making injectors for ,11 years and can tell you that its impossible to do the job properly at home. Yes you can strip and clean them but you cant reset opening pressure which WILL change as soon as you dismantle the injector, you cant check the spray pattern properly and you cant check wetseat or backleak time. You need very special very high pressure expensive equipment to do any of that.
I believe with a common rail system, you are using the electrical connector to open the injector. Furthermore, the PCM can smooth out idle pulses by watching the change in rpm as each injector is fired. During acceleration, the smoothing doesn't matter anymore and the watches other inputs such as rail pressure, boost pressure and the air fuel ratio at the exhaust plus temperatures. Modern Diesel design and computer control systems allow for fine adjustments. Due to manufacturing variations, auto makers have several programs to fix injector imbalances on all gas and diesel engines. Cleaning the injectors at home will improve their flow and spray pattern. The tip does wear over time allowing more fuel to flow than set at the factory but the automakers have a mileage adjustment as well in their fuel calculation.
I work in the trade since the late 1970s and I never ever saw the opening pressure of an injector change drastically after dis- and reassembly. If you put the tips in the same injector body they came out of, you will be fine in 99,9% of the cases. I also think it is much better to drive with a cleaned injector which is a few bars off than drive with a carboned up and leaking one.
The best way after cleaning is just put injector on bosch maschine to generate new ima code. Thats all. Then injector can working totaly properly. Of course when is not damaged. New ima is ~20$ pro pice
hi, great vid! Any suggestions on how to get the entire piece to such lovely state overall without the sonic-magic? I've suffered "black death" on my Benz W211 220CDI engine, removed those puppies out, want to get them to best possible state before referring to specialist (should save $$ as it saves them time). Thanks in advance for your response! Greetz from Poland!
You may try soaking the pieces in carb cleaner. Some have tried polishing the needle with a jewelry polishing compound and a rotary tool but make sure not to overdo it. However, you can’t thoroughly clean the insides of the nozzle this way. Another youtuber have tried cleaning the nozzle tip holes using a single thread of a small wire brush for his clogged nozzle and it worked for him. I haven’t tried and can’t guarantee this method but it may help. Just make sure every piece is well lubricated upon assembly and the needle slides smoothly in and out the nozzle. Thanks!
Probably you’re the only person can answer my problem… So my injectors were very noisy (knocking sound), when engine was could was ok but after was worming up was making loads of noise and the engine idle was not smooth. I’ve followed your video by the book, and I must say that the injectors act completely as new, no knocking sound at all, amazing while driving, probably the smoothest time this engine run. The only problem now is that all this hold for 1 day, the knocking sound starter to get worse hour by hour up to the point that it get back to where it was. Now when warms up is noisy and the idle is irregular. What I’m missing? Are these injectors unrepaireble? Do I deal with some other issue? Might be the the fuel/tank is contaminated?

Please your information - what minimum power in Watts and frequency in kHz
must an ultrasonic cleaner have to reliably clean the injection valves, nozzles ?
Thank you for your answer in advance.
If you have had a catastrophic HPFP failure on a vw 3.0L CATA 2011 Touareg are the injectors salvageable? Can I clean them and reuse them or are they scarp? Do the aluminum particles from the HPFP do damage to the injectors that can't be fixed?
It depends on how long you were still running the engine after the HPFP was shot. Try to check the fuel rail and pipes first for debris. If you find any, it’s best to bring the injectors to a professional who can fully take it apart and run it on a bench test machine.
Excellent job... can you do this same type of video with Yanmar 6LPA?! Thanks!
I love the video, that's exactly what I was looking for. thank you for such all around beautiful video. Questions: what kind of ultrasonic liquid did you use? where can I find the torque specs for my Bosch injector? TIA
What type of cleaning fluid do you recommend and is this a high alcalic solution?
Do the process is the same for high pressure diesel injectors, like Bosch using in VW group CRCA 3.0 TDI engine?
Great video, what solution do you use in the ultrasonic?
5:18 Perfect atomization of the nozzle.
Thanks for the video, should we need to calibrate them after cleaning?
No need if you returned the exact same parts :)
Hi, great video very detailed and clear, would this process work with a 1.6 Tdi Fuel Injector Unit 03L130277S made by Continental.
These new are approx. £450, so would love to be able to clean my old injectors if possible.
Any help and advice would be most appreciated thank you
Hi! Continental injectors are more complicated, it’s best to have it serviced by a pro :)
Those things are the curse of VW owners.
I fully agree with that statement @@jeremytodd4906
@@jeremytodd4906 Yes don't l know it,as do thousands of others. My first and last VW
Brilliant.
What type / size of engine do they belong to?
Being that big I believe it’s got to be a truck‘s.
Same size as my Audi A3 1.6 tdi
When new injectors are fitted do they need coding on 2010 volvo xc90 diesel
Do refurbished nozzles provide the same level of fuel efficiency as new nozzles?
Hi Matthew! I’m not sure, it depends on the supplier. I’d recommend brand new ones for peace of mind
What is the Assembly torque?
Really well instructed video, what type of ultrasonic cleaner machine do you use and what solution do you use for cleaning.
Thanks

Hi! Got the tank from ebay. Says it has 50w u/s power, 40khz frequency and a 100w heating power at the back. Not sure if it’s really accurate though. Regarding the ultrasonic solution, it’s a custom mix we get from a local supplier here in ph. You can find a lot of them online, just get the ones that are aluminum safe. Thanks for watching :)
I'm looking for one too.
Allen Dale ultrasonics in the UK have all sorts. I'm going to get a small one. 50 quid. 🇮🇪
Hello. Is it a concetrated cleaning solution? What do you use for mixing? Water? Thanks.
If you rinse and oil the parts IMMEDIATELY after taking them out of the cleaner, dishwasher powder in about 60 degrees C water works incredibly well.
But you really have to rinse and oil the parts immediately after taking them out of the bath. They will develop surface rust in mere minutes and then they are destroyed.
Wow, you deserve a beer for sharing this sorcery. Out of curiosity are these Bosch 110 or 120 series or anything else?
Will it help if my turbodiesel smokes black on acceleration? Everything else is checked. The mileage is 265.000 km and I believe the injectors were never out of the engine.
Yes it might. If not, best to have them tested at a reputable shop. You might also want to check your turbo and air intake system since you’re getting black smoke, you might be running rich, too much fuel, lack of air.
Superb thank you very much for taking the time to do this video I’m very grateful 👌
Does the body of the injector ever need cleaning out, once you've removed the shims and spring? Or is that part generally clean?
Hi Paul! Not really but it wouldn’t hurt to pour some diesel in the holes while it’s upside down then quickly turning it upright to let it drain. Carbon buildup usually takes place in the nozzles. In some cases though where the injectors get contaminated by water or particles from dirty diesel, the injectors will require a complete tear down/reconditioning but it’s best to let a professional do it.
What type of solvent do u use in the ultrasonic cleaner :) ?
What solution is best for cleaning diesel injectors?
Hi great video! is it necessary to adjust the injector on a special machine after this cleaning? thanks!
Basically, all injector calibration codes are inputted in the ECU from the factory. These codes help the ECU determine the specific output flow of each injector as no injector is exactly identical. Now, wear and tear or repairs such as replacing some injector internals with bnew ones will give a different output than the programmed data in the ECU. This scenario requires a special machine such as Hartridge Injector Calibrators to generate new calibration codes for each injector then you can input these codes in the ECU using a scantool with an Injector Coding function. If you just cleaned the internals like we did in this video and didn't notice any loss of power and high fuel consumption afterwards then you're fine. But if you did, It's best to bring your unit to a calibration shop that can test/read and generate new calibration codes for your injector.
@@btdgarage Hi, thanks for very detailed explanation!!! it is very clear now!!
another question and last one is if is necessary to ANNEAL the washers under the injectors before mounting or not? Thanks again :-)
@@martintoman6266 Thanks Martin! Annealing the washers isn't necessary but also not a bad idea if done properly.
how did they work i feel like putting it on the vice like that can allow the body to twist/ warp the two flat spots is where I would grab it
No doubt you are a Pro Liked the quality and standards
Thank you
What are the Torque settings
Nm
Please

Excellent. Are the shims ok either way up?
Is the cleaning solution in the ultrasonic cleaner just plain water?
Could I slip in a DLC needle in the reassembly ?
Great video, how many nm torque for tighten the nozzle? Thx
Hi! 50Ft lbs or 67nm. Thanks!
What if injector has too much leak? This only works good but dirty injector.
You’ll need a complete injector rebuild/repair in that case
I worked in a factory making injectors for ,11 years and can tell you that its impossible to do the job properly at home. Yes you can strip and clean them but you cant reset opening pressure which WILL change as soon as you dismantle the injector, you cant check the spray pattern properly and you cant check wetseat or backleak time. You need very special very high pressure expensive equipment to do any of that.
Bullshit.
So should I go and buy new injectors for my smoky ford 3600
I believe with a common rail system, you are using the electrical connector to open the injector. Furthermore, the PCM can smooth out idle pulses by watching the change in rpm as each injector is fired. During acceleration, the smoothing doesn't matter anymore and the watches other inputs such as rail pressure, boost pressure and the air fuel ratio at the exhaust plus temperatures. Modern Diesel design and computer control systems allow for fine adjustments. Due to manufacturing variations, auto makers have several programs to fix injector imbalances on all gas and diesel engines.
Cleaning the injectors at home will improve their flow and spray pattern. The tip does wear over time allowing more fuel to flow than set at the factory but the automakers have a mileage adjustment as well in their fuel calculation.
I work in the trade since the late 1970s and I never ever saw the opening pressure of an injector change drastically after dis- and reassembly. If you put the tips in the same injector body they came out of, you will be fine in 99,9% of the cases. I also think it is much better to drive with a cleaned injector which is a few bars off than drive with a carboned up and leaking one.
The best way after cleaning is just put injector on bosch maschine to generate new ima code. Thats all. Then injector can working totaly properly. Of course when is not damaged. New ima is ~20$ pro pice
hi, great vid! Any suggestions on how to get the entire piece to such lovely state overall without the sonic-magic? I've suffered "black death" on my Benz W211 220CDI engine, removed those puppies out, want to get them to best possible state before referring to specialist (should save $$ as it saves them time). Thanks in advance for your response! Greetz from Poland!
You may try soaking the pieces in carb cleaner. Some have tried polishing the needle with a jewelry polishing compound and a rotary tool but make sure not to overdo it. However, you can’t thoroughly clean the insides of the nozzle this way. Another youtuber have tried cleaning the nozzle tip holes using a single thread of a small wire brush for his clogged nozzle and it worked for him. I haven’t tried and can’t guarantee this method but it may help. Just make sure every piece is well lubricated upon assembly and the needle slides smoothly in and out the nozzle. Thanks!
Probably you’re the only person can answer my problem… So my injectors were very noisy (knocking sound), when engine was could was ok but after was worming up was making loads of noise and the engine idle was not smooth. I’ve followed your video by the book, and I must say that the injectors act completely as new, no knocking sound at all, amazing while driving, probably the smoothest time this engine run.
The only problem now is that all this hold for 1 day, the knocking sound starter to get worse hour by hour up to the point that it get back to where it was. Now when warms up is noisy and the idle is irregular. What I’m missing? Are these injectors unrepaireble? Do I deal with some other issue? Might be the the fuel/tank is contaminated?

hi can i clean injector from skoda superb 103 kw Common rail like in your video?
A great video, a question for all Bosch injectors, is the nozzle tightening torque the same or does it change?
It is 80Nm for the old indirect injection ones and 45Nm (or 30 degrees after seating the collar) for the two-stage TDI injectors.
Nice video thanks 👍 keep up with your great work
As you answered the question about taking it to get them calibrated, would I need to know the number codes of 123&4 or does machine find them thanks and great vid tutorial
The machine will generate new codes for your injector. If in case you're buying a new set, use the codes located on top of each injectors. Thanks!
