DIY Diesel Injector Cleaning with Liqui Moly Diesel Purge Plus Volkswagen Polo TDI 2011
HTML-код
- Опубликовано: 12 сен 2024
- Here is a detailed how-to on DIY diesel injector cleaning using Liqui Moly's Diesel Purge Plus injector treatment on a 2011 VW Polo TDI. I detail all of the required parts and tips and tricks on how to compete the injector cleaning.
I found the TDI ran quieter after the treatment and felt more spritely and smooth. For $20 all up, it was worth a try as the injection system on these modern cars is upwards of $2000 - good to look after them and try to keep them clean.
Let me know if you need any help - I'm happy to.
Good tip about using an inline filter. Several videos on RUclips showing diesel injector cleaning using this method but you're the first to show using a filter to prevent any dislodged debris from being drawn back into the pump and injectors via the bottle of injector cleaner. Great video! 👍
Thanks! It’s really important to stop any debris getting into these injectors as they’re so fragile internally, so the filter is a good thing to use.
Thanks for watching!
I think maybe it's because other people used the engine's own filter. But This car does not allowed that!
Very good video. Mine is in the post to try on a focus 1.6TDCI 117K miles. Your demo has cleared a few things up for me, that I was unsure about.
Cheers mate, thanks! I hope it all goes well for you
By far the best tutorial on this subject, thank you man
Thank you!
Thanks a ton. This is exactly what i was looking for. I also have a filter with only two ports exactly like you. I wasn't able to identity fuel lines because all videos of diesel purge with tdi show filter with four ports. Btw i own a variant of polo 6r known as polo sedan in some countries and vento in india.
+shariq islam Cool! Good to know it helped you out.
The best video I have seen on this subject
Thank you
you said it all without any words ,it may be helpful to me as my passate has fuel line set up similar
You could have taken the fuse from the tank pump, and saved one step in the job, right?
Notice you had the date and miles on your fuel filter. Good tip.
+tom Yeah let's me know when it was last changed. Thanks for watching
Hi Alex! I tried the same procedure on the 1.6 TDI Polo but somehow the engine refused to start after attempting at least 6-7 cranks. I'm guessing this could be due to air in the fuel inlet line? It kept cranking but never started. I had to call it off. Besides, I was wondering, why not remove the fuel pump fuse so that the pump doesn't push the fuel from the fuel tank during this procedure? When I connected the hose between the fuel filter inlet and the return fuel line, the hose became bloated! I was worried if it would rupture. Luckily I couldn't carry out the procedure. Pouring the diesel purge solution into the tank is an alternative but not as good as this process I bet.
+Ganesh Balan Yes you must have managed to get air in the fuel line which stops the injectors working. Does the car work now?
alexaescht Yeah it worked after I reconnected the respective hoses back. Tried it a second time but the engine didn't start despite multiple cranks. Gave up and poured it inside the fuel tank. The tank had very less fuel; less than half of the reserve.
+Ganesh Balan At least you didn't break anything!
Haha *touchwood* I hopefully didn't. :) But after pouring the diesel purge into the fuel tank and revving the hell out of the engine, I think there's a perceptible difference when we went for a drive yesterday. Thanks a bunch for all the help Alex! Appreciate it man.
+Ganesh Balan No problem. Glad to hear it's made a difference
Awesome video. Thanks for sharing!
Good tutorial video for diesel purge
Thank you for watching
I think you should also advise people to fill the inlet type with some diesel so it doesn't run dry for too long
+why must i chase the cat If you disconnect the inlet pipe and put it straight into the clear line, then in the can, there is barely any air in the line at all that it doesn't matter. Only matters if you're using a really long line into the purge for some reason.
Really helpful video. By the way is it a good fit when putting the 8mm vinyl tube into the cars fuel hoses, does it seal easily ?
I like your video. Very informative. Subscribed to your channel immediately. But I have zero knowledge about car engines xD and in India is really difficult to source these items.
But I will get a liqui moly and add it to a full tank .
Is that method not as good as the complex one you have done?
Any benefits to doing it your way ?
I have a 1.6 polo TDI 2013.
Really helpful videos thank you. Nice and clear too.
Thanks for the kind words!
The filter should be on the intake pipe
Hello great video, I have 3 ports on my injector pump, 1: supply line to the pump 2: Return pipe from injectors connected to injector pump, 3: I don’t know what that is, if I was to take the pipe off the return and use that as return wouldn’t diesel come out of the port on fuel the pump
you could connect the inline filter to the intake line.
Hi I know this is an old post but very helpful nether the less.
I have one question and that is would it be better with the fuel filter on the flow in pipe not the return one, also the flow pipe just short by 5mm of the base of a clear jar.
Hi, thanks for watching. I think having the filter on the ‘in’ pipe would be fine also. I think the reason I chose to have it on the return was just to make sure I didn’t fill the pump up with air from the filter. I agree a clear jar would be useful too
Would a simpler way of working be in like the liqui Lily adverts say? Just disconnect fuel filter pipes and place in the diesel purge can? In another video hardly any gunk came out from the injectors. Would it probably break down and be absorbed and be burnt away anyway?
I think either way will be fine. I just wanted to be cautious and use an extra filter to be sure
Hi.You said in the end:do not allow all can to empty.How do i know when the can is close to being empty?Thanks
Thanks for your comment. I used a torch to look into the can and monitor the level. When it got low, I stopped the engine
Thanks for reply!
Hi, why did you put the filter in the return line? the filter should be placed on the line going to the high pressure pump (hpp) right? please clarified. and what about priming of hpp, it looks like you started the engine directly. finely what about the results did it works? thanks
It doesn’t matter whether the filter is on the inlet or outlet line because we assume the the can of purge starts out clean. Putting it on the return line was easier as it meant we didn’t have to bleed air out of the filter to stop the pump filling with air. Results are good. Better response and quieter running
Thanks for watching and commenting
This injector cleaning? Says under the video that it bypasses the high-pressure pump and the injector
Just wondering if I could use the exact setup you used in your video for my 2010 Golf 1.6 TDI?
Hello!
used condensed without dilution? It is theoretically recommended for 75 liters.
Nice video, is it worth replacing the fuel filter and siphoning out all of the fuel then repriming it with VCDS to make sure your using fully cleaned fuel
Thanks! You could do that, but it’s probably overkill
Good video! I have old car. It's PLUNGER engine. can I use for my car?
Shouldn't you prime the feed pipe with the LM b4 starting?
Hi did you solve your problem after cleaning?thanks
Hi, there was no problem. This was some preventative maintenance
Thanks for watching
Hello,can you just add it to tank fuel?
Hi, you can add it to fuel but it is less effective that way.
Thanks for watching
How effective it is..
What if l use two bottle .one for diesel back from injectors and another for purge cleaner.l think in that case purge will stay clean from diesel
+elshadaj dooel that might work. Not sure
you will run out of purge really quickly. you need to re-run the returned fuel back again, because not all of it is used up by the engine.
I have petrol car shoul i use liqui moly injector cleaner will it make any difference?
is that rig filter arrow going away from the can or toward?
great clear vid! I was wondering how do you know when the liqui moly is nearly ran out?
Thanks! I just used a torch to shine light into the container to view the level of the liqui moly
Use a clear container. Run the hoses into a clear container then pour the Liqui Moly into the clear container.
one pipe from the diesel filter is for high pressure pump....but what is the another pipe in the filter for...??? which line did u bypass the return...??
There is a lift pump in the tank that runs constantly with ignition on. You have to recirculate that back into the tank otherwise you’ll have diesel spraying everywhere during the purge
Hi mate,
I'm having some problems with my polo 2010 TDI, if I'm on a motorway and let the RPM fall below 1800 on 5th gear going uphill, it seems to lose its power a lot. The dashboard asks to go down to 4th then 3rd gear and the speeds stays at around 50mph until the hill is over, then it seems to get all of its power again?
Thanks in advance
+LushiiiPlays This could be normal behaviour; the Polo TDI puts out it max torque at 1750rpm and it does drop off below that a fair bit. It could also be due to a dirty air filter, faulty injectors or a blocked DPF (Diesel Particulate Filter)
thank you, i will get this checked!
Is it safe to use? I mean, the lubricity of LM DP is unknown and high pressure fuel pumps of vw cr engines are very sensitive to fuel, it can start to "fall apart", and the faulty pump work could be noticed not immediately after the procedure, but in 10k or 20k km. Was thinking of using it, but now I get second thoughts..
+Julius Barančejevas Many people have used this stuff with CR diesels and haven't had issues. It's diesel-based anyway and shouldn't cause any issues.
what is the interval for fuel filter replacement?
+Nikhil Patil 60,000km in normal conditions or 30,000km in severe conditions
alexaescht In india vw force us to change it on 15000 km. May be because of bad fuel quality and mixing of kerosene in diesel.
+Nikhil Patil Yes in some markets the interval is short (15,000km) due to poor quality fuel.
alexaescht you oil change videos help me a lot for diy oil change. Thank you.
I like that you talk in your videos. It help to understand engine and other sounfs at diffrent condition.
+Nikhil Patil Thank you for taking the time to comment. I am very happy that these videos have helped you!
What do you think about adding a 2-Stroke Oil in Diesel?
+Lukica Stipetić Never tried it myself but I've heard it does good things.
Retards the ignition and does sound quieter and smoother. However this is because the bang is smaller therefore your engine will be less powerful.
You could have attached the hoses directly to the IN and OUT hoses on the filter, no need to the inline filter
Hello alexaescht:
I'm writing you form Mexico, I have a VW Vento 2014 (a sedan version of Polo in Mexico), and my car have the same engine as the video, a couple of questions will help me a lot:
As you'll know, in Mexico we have a poor quality in gas and diesel, so, how often do you recommend me to change the diesel filter, and, how often use DIESEL PURGE?
On the other hand, when should I change the viscosity oil? (saying something: after 50,000 km use a SAE 5W-40)
Best regards, thanks and sorry if my English is not good enough.
Alan.
+Alan Hernánez Perea Hi Alan, your English is very good! No need to apologise.
Firstly, I would recommend to change the fuel filter every 30,000km. VW recommends to replace it every 60,000km however in areas of poor quality fuel, 30,000km will be more appropriate.
Diesel Purge is the sort of thing that I would only use roughly every 60,000km (every second diesel fuel filter change). Make sure to run the diesel purge before you change the filter, not after.
With the oil, I recommend staying with the VW Specified 5W-30 until at least 200,000km. Only change to a heavier weight oil (eg 5W-40/10W-40) if the engine is burning oil between oil changes. If it is running fine, and not burning oil, then stay with 5W-30. Make sure you are using high quality, synthetic, VW approved oil to ensure the engine and exhaust system lasts a long time.
I hope this answers everything, but if you need any further help please let me know.
Regards, Alex.
Thanks Alex.
It helps a lot, have a good day.
Regards! Alan.
hi, i have a suzuki swift 1.3 ddis with fiat multijet engine,
whats are the difference for doing the same thing on my engine?
+Simone Pusceddu I am not sure about that engine as we do not have it available in Australia
ok,thanks mate
Que es ese zumbido o silbido que suena al acelerar , en mi coche lo hace pero mucho mas fuerte , mismo motor
where did you get the tube to hose joiners, eg, used to connect the clear tube to the black hose.
The clear tube fit inside the black hose. No joiners were necessary
Thanks! Very helpful beacause i have a 1.6 tdi engine in my Skoda and i have the same tube lines.
Thank you for watching
@@YZJB I just finished the cleaning. It was done with great success and in the filter I had put in the return there was a dirty settling. The only problem is that as soon as I started the engine worked normally but after a few seconds it turned off and now it does not start. I'm waiting for the engineer to start because it obviously blew air.
So is it safe to use this method to clean the Diesel injector? Because You said after few seconds got problem
@@Mathu81 It is safe. You just have to be careful not to blow the air because then it does not start. But even that is easily solved
Thank you for your Response,
May i know How the Engineer solved it easily after Air blown inside?
It can be used for 1.5 L diesel also
Yes it should be a similar process
How can i get my car to stop going into limb mode i changed the ecu and turbo and injectors but still got the pig tail alarm coming on after about 2min of idleling i had the car decated and the bloke who removed the dpf messed up by not sealing the ecu so it got wet thats why it was changed
When i start the car there is a light that comes on it look like a light bulp it stays on and then the pig tail light comes on what to do next
What will be the benefit of using, please tell....
Cleaner injectors
Many thanks
How often do you think a diesel engine would benifit from this? Every year? Or how many miles? Thanks
+Faith Airey Of course usage, engine condition etc would vary the interval, I'd say every 80000-100000km (50000-60000mi) would be a good starting point.
Thanks a lot.
+Faith Airey No problem. Thanks for watching!
can be putte directly in tank an mixed with the regola diesel ?
+Liesdanys Campillo Yes it can be put straight into the tank, but it is more effective to run the engine straight from the bottle.
Ok thanks but in my car is hard ..bmw e90 has down the filter :( ... thank whatever i put on tanks and make his work for now is ok
Good clear video.
Thank you!
great video!
i have a vw polo 2012 tdi 1.2 engine code cfwa
this engine type has a diffrent feul line setup like the 1.6. i'm finding it hard to do a liqui moly flush directly because of it. do you have any experience with this type of engine?
i was thinking to just poor 4 or 5 cans (2-2.5l) into a half fild thank or les that should do the same thing. what do you think?
i do the maintenance my self sinds i bought the car new from de dealership. it now has 269000 km on it and running perfect. eating just 0.7 liters of oil on 30.000k. i'm from holland and i always buy diesel from shell.
+jammal ghma Yes, adding a lot of the flush into a nearly empty tank will do basically the same thing. You could also try working out the fuel lines and doing it the way shown in the video, but it doesn't really matter.
Very glad to hear yours has done so many kilometres and still works fine! Must be a very solid engine this version of TDI (even if it does cheat emissions!)
Thanks for watching
I have the same engine, and I would replace the diesel filter. I am not sure how to prime the filter after the change. How you did it?
Modano Relloi i youse a vacuüm pump to suck the diesel trough the filter. the next time i will do that aigan and activate the lift pump in the tank with vcds.
+Modano Relloi Cycle the ignition key until the filter is full, and then connect the output hose to the high pressure fuel pump
+Ilias Vamos You can just cycle the key until the filter is full
Hello sir my name is sandy I am from India I am auto electric engineer . One of my friend car vw vento the car make more noice when the ac compressor on fuel injection noice can u tell me how I solve this problem ?
Isn't this harsh on the high flow pump? Running it dry
You aren’t running it dry if you do the procedure properly. You must be careful not to introduce air into the system

You might have introduced air into the injector pump
@@YZJB Is there anyway i can avoid it ? Do it without introducing air ?
@@YZJB Would appreciate an help. Thanks in advance.
Hi, if i have the fuel pump into the tank will not possible to do this,rigth?
I’m sorry, I’m not sure what you mean
@@YZJB I mean that for example my alfa romeo 156 2.4 jtd 10v 1999 have the electrical pump into the fuel tank, so if i make a bridge from return of the rail, the engine wont be able to start because will not have pressure in the rail.
Where is the oil filter octavia elegance 132 is it under the engine
It should be on top of the engine on the left side of the engine bay when viewed from in front of the car. I believe it uses an insert-type oil filter like this Polo does
I must caution you here, that the fuel injectors are continental make and are very expensive. at times this method cleanse the engine intake lines only not the entire system. And most of the times it leads to failure of injectors. The best practices are is to clean the entire fuel tank properly, change filters and clean the fuel pump too and is advised to use the purger with the full tank Diesel... Over a period you'll notice the improvement in performance...
Hi, thanks for the video. My engine is somewhat similar but has three lines coming out of the engine to fuel supply. I have polo 2016. Can you help? I will mail you my engine pic.

Got a pregio diesel in australia, withe smoke and every week i purge the filter, air is present and i dont find the leak, mechanics are expensive looking for any solution.
Use a lighter. When you find the leak you will know 🤣. Sorry mate I had to. Did u find a solution
will260007 pregio van leaved on the junk yard, lost all my money. now homeless no more van on a bench in a public library.
Sorry dude. Had no idea.
I've done exactly that on my SEAT ibiza 2009 with 105000km ! Except I
continue till the engine stop by itself ... and then I couldn't restart
it. I knew it was because air got into it. I have been recommended to
spray some toilet freshener into the tube that goes to the air filter
which I did ! After a small explosion sound: The car started
straightaway.
The only thing is, since then, purging and all ... the car makes a sound
of vibration which I can feel on the pedal while passing the gear 1 and
2....after pushing the accelerator the vibration goes away. I've been
told it was the flywheel .... why ? Is it because of the purge ? Do you
know what went wrong ? .....Thanks for reading this !
+Alain Jean Sorry to hear of the problems you had. The vibration may go away after a week or so of normal driving, however if it doesn't, and the flywheel is faulty, the flywheel wouldn't have been broken by using the diesel purge - it would be faulty for another reason. Also, you may have only noticed this vibration after the purge, even if it was always there but you had never noticed it before.
Hope that helps.
+alexaescht thanks for your explanation. At least, that's a relief that it didn't come from the purge. However, after a month or so the vibrations are still there. One thing I forgot to mention is that while the liquid was purging the injectors I was accelerating till 2500 rpm ... that Also wouln't have hurt the flywheel ?
+Alain Jean Doing that won't hurt the flywheel in any way - it's impossible. The damage would have been caused from something else, or even just through wear and tear. I know these flywheels can fail at relatively low kms.
I believe what you are saying...it's probably from something else. Thanks alexaesht for your input and all !
+Alain Jean No problem
hello.
thanks for video.
i am wondering if it working with LIQUI MOLY super diesel additive
+abdallah boughaba The diesel additive is meant to be added to the fuel in the tank, not to flush the injectors like in this video.
Hi. What is the Moly reference ? 5170 ? Thx
Sorry I’m not sure what you mean
@@YZJB ok don't be worry about this. I found the product name for my country
Why you using this for your engine what have a problem?
Diesel purge can be used for maintenance; to keep the injectors clean
Why not just dump it inside the filter?
1. You can’t open it up on this model
2. A lot of the fuel gets returned to the tank after the filter, so it would be diluted instantly
Shell v power does the the action?
This is an extra step if you are having injector problems
@@YZJB I have driven 35000km TDI engine now I didn't have any injector problem but can do this ? In order to prevent from future problem
Termination U it will not hurt anything. It will help to keep the injectors clean
WHY NOT just fill the fuel filter can with Liqui Moly instead of disconnecting lines
I want to do it. kindly advice for the same. i want to put it in my filter
I have a 2016 model polo 1.5 tdi , i have followed the same step as shown in vedio but my high pressure pump is not sucking purge from the bottle and engine wont start

It looks like you did not purge the hose of air before starting the engine
@@YZJB How do u do that?
You have to pull the cleaner through the hose with either a pump or by sucking it through carefully. If you get a lot of air in the fuel pump the engine will not run
@@YZJB so the fact it started sucking into the motor is irrelevant?
It would have sucked a heap of air in first
Hi there can the contents of the Diesel purge be dispensed into the feul tank? Or does it have to be done this way?
Both ways ...
is that rig filter arrow going away from the can or toward?
+Jessica White The oil filter cartridge is labelled with 'top' or 'bottom' and you just have to put it in the correct way. No arrow
+Jessica White Sorry I got my videos mixed up. The filter is on the hose that goes away from the can of diesel purge. Thanks
