Thanks for the video. You should've mentioned that you primed the feed line before attaching it. This is absolutely crucial to avoid destruction of the high pressure pump.
Awesome. Just did it. Jetta TDI 2007 Mex. I saved some hose to make an u on the filter and avoid fuel spill that the tank pump is pushing. Make sure the bottle where you pour the liqui moly diesel purge is made of glass since the fuel coming back from the return line gets hot and a plastic bottle could be compromised. Keep posting this fantastic ideas. Saludos!
You can also just put the two hoses straight into the Liqui Moly container as they advise on the side of the can. This eliminates the need for a glass jar etc.
That would be the easiest way but I decided to put it in a clear jar for video purposes and to show that I left a little bit of the Liqui Moly in the container but the original can works just as good.
If you put an inline fuel filter in the fuel line like I did in the video, the contaminates will get filtered out before returning to the injectors so I don't think using two jars would have a noticeable effect. Also compu85 is 100% correct the color change is the diesel being mixed in.
I used this stuff on a TOYOTA 2KD-FTV engine the results were amazing just remember to put a brand new fuel filter after you're done with the treatment I put my filter wrong, now my injectors are dirty again
Frankly, I would avoid bypassing the fuel filter and putting any product directly into the injectors. 5-7 micron particles are the trouble makers. What did the exhaust look like during the process? I'm also surprised return cleaner did not seem to have any darkening effect on what was left in the bottle (see above). Guess everything that was cleaned out was micron size 😄. If cleaner is added before the filter, junk will be captured.
You could do that, but the fuel injection pump is recirculating and therefore will dirty up the new filter from the contaminates that were on the injectors. Also, the Liquid Moly will get slightly diluted by recirculating into a fuel filter that is slowly feeling up with diesel fuel.
I'm surprised you didn't have fuel spraying from your filter. I always connect the two open ports on the filter with a clear tube because the lift pump in the tank is still sending fuel through it once the engine is running
I noticed the one mason jar had both supply and return lines. I also noticed the gunk that got returned to the one jar Would it not be better to have two separate jars with a lot of the diesel purge in the supply jar and a small amount in the return jar?
just what i needed plus bonus float on. i was told just to stick this in my fuel tank any truth to this?obviously at the end you said put the remainder in
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 My guess is that the "small explosion" sound you heard probably put a lot of strain on your motor mounts and probably broke one of them. I would recommend keeping the toilet freshener in the bathroom next time and just cracking loose a few injector lines to bleed the air out.
+Tyler Evans Thanks ! Unfortunately, I was thinking the same thing: my friend recommended me to use the toilet freshener which after all wasn't a good idea...
B4 you replace fuel filer which a good size fill filer with purge and reconnect feed and return line then prime and Start engine let idyle and repeat lot easier
It doesn't matter, the fuel filter is bypassed as the engine is running solely on the diesel purge. The mason jar acts as a small fuel tank thus the fuel filter is not filtering while running the D.P. change the filter after if you really need someone to tell you what to do...
Better to do before changing the filter. Lubro Moly also recommends filling the new filter with Diesel Purge. I run some fuel system cleaner through the tank before changing to a new filter. It helps catch moisture and contaminants in your old filter. Keep your new filter clean. Adding fuel treatments every 5 tanks of fuel keep the system and injectors clean. I gained 5 mpg using these treatments since buying the car.
To clarify, I'm looking at Liqui Moly Motor Clean, not Liqui Moly Motor Oil Saver. Now I see you are demonstrating an entirely different product. My bad.
john balogna My Jetta is a 2000 but the 2004+ TDI's have the in tank fuel lift pump so if yours is a 2004 then you would have to remove a fuse. ht tp://ww w.myturbodiesel.c om/1 00q/pumpedusedesc.htm
VincenzaV1 I found that it really helped my idle and mpg but I guess the results will vary for each car depending on how much your injectors are clogged to begin with. Mine were clogged so I noticed a difference but if you have low miles or fairly new injectors you probably won't notice a difference.
Tyler Evans Cool! Same thing for Seafoam. I have a one owner car with regular maintenance (Dealer). It has 163K on it (2004) so I guess it won't hurt. It runs freaking awesome right now, so I may not experience any changes. Better MPG's are always welcome though. Thanks for your response!

hussayn19 I'm not familiar with the t5 engine so i don't want to tell you wrong but the Liqui Moly is a Diesel additive for all diesel engines but I'm not sure how your ECU would react if you ran it straight into the injector pump like I did on the MK4.
Hey i used Liqui moly super diesel additive in my 1.9tdi diesel skoda octavia 2007 and it made my engine smooth . No proplem occured. Now i want to try lm purge. Is it safe?

hello, i done same to my Audi A8 2.5 TDI but when car stand off all night, tomorrow morning i won't start the engine, i must done the same as you, and then all day i dont have any problems (off on) no problem, but just when car stand off longer then i can't start "as disel don't have" all disel from from slanger going back to the tank!! what's the problem have my car! can you help me?
I just watched my car being taken away by the pickup truck. I followed all the instructions in the video but when I reconnected the lines it wouldn't start again. Tried everything to get rid of air in the pump(supposed prob) nothing worked. 2002 v6 diesel Passat. Icould get fuel to go into the system after the filter, and return after the pump, but no go, not even a cough! Saw one youtube which recommended using a vacuum pump to bleed the air but don't have one, can't buy one...Murphy rules!!
+DiMz707 I just have it in neutral revving the engine to burn the Liqui Moly faster you could just let it idle but it would take a while to burn all of it.

I have a Jetta 2005, 1.9 tdi and I sow same video, they are doing that without filter. Is that possible?
@@mwolf8863 yes but why? Filter is cheap, injectors are expensive. It’s cheap insurance.

Thumbs up for the TDI Club!
I have also heard to shut off engine midway and let the injectors soak in the stuff for 20 minutes and then flush it
me and my 3 y.o loved the music, we danced to the video ha.thanks
I used this stuff on a TOYOTA 2KD-FTV engine
the results were amazing
just remember to put a brand new fuel filter after you're done with the treatment
I put my filter wrong, now my injectors are dirty again
2:08 Revolving oil tank cap lol
No. What is spinning is the rubber ring that is used when the engine cover is on.
Frankly, I would avoid bypassing the fuel filter and putting any product directly into the injectors. 5-7 micron particles are the trouble makers. What did the exhaust look like during the process? I'm also surprised return cleaner did not seem to have any darkening effect on what was left in the bottle (see above). Guess everything that was cleaned out was micron size 😄.

You could do that, but the fuel injection pump is recirculating and therefore will dirty up the new filter from the contaminates that were on the injectors. Also, the Liquid Moly will get slightly diluted by recirculating into a fuel filter that is slowly feeling up with diesel fuel.
Don't forget to pull the fuse out for the diesel lift pump.. Before you start purging 😬
No lift pump on an ALH engine.....
The most important part.... If u want to avoid diesel on your engine
@@rwthomas1^^^
I just learned this the hard way.
learned this the hard way hahaha
I'm surprised you didn't have fuel spraying from your filter. I always connect the two open ports on the filter with a clear tube because the lift pump in the tank is still sending fuel through it once the engine is running
1.9tdi with rotary pump dont have pump in gas tank, only rotary pump draw fuel to engine from tank.
What year? I know all the MK4 have lift pumps in the tank
It is a 2000 Jetta TDI :) no lift pump...
Strange because according to the Bentley manual it has one.
Only the PD engines have lift pumps (starting in 2004)
I noticed the one mason jar had both supply and return lines. I also noticed the gunk that got returned to the one jar Would it not be better to have two separate jars with a lot of the diesel purge in the supply jar and a small amount in the return jar?
Even i was think the same , that would be a top notch result
you are used only purge or mixing purge with diesel?
just what i needed plus bonus float on. i was told just to stick this in my fuel tank any truth to this?obviously at the end you said put the remainder in
Is it not much easier to do it when you install a new diesel filter, and top the empty filter up with the purge liqiud
no, the purge will just be dilluted into the 15Gallon fuel tank and will be much less effective
How will it dilute? The fuel runs from the filter to the injectors, not back to the fuel tank.
Can I pour directly inside the fuel tank?
Yes, I believe that is another method
i like your crankcase breather pipe
Is this the same process on a vito 639 2.1 2007
beautiful video

Another possibility for vibration is that if your engine gained some ponies and Nm more stress is going on to flywheel and makes it vibrate.
Air-locked, google it. mighty-vac good luck. #whatnottodo
You can run straight biodiesel to clean the fuel system including the injectors.
Bio diesel kills injectors.
Even better with dishwashing detergent or TNT
Do not run tdis on bio diesel.
@@chaseandrews9354 I do it all the time!!!
Would it be ok to just empty the filter andpour the liqui moly in the fuel filter and then re-connect and just let it run through without the jar?
If you watch the SeaFoam video, that is what they do. Seems easier huh? th-cam.com/video/544E_X2oUgM/w-d-xo.html
That’s what I do!
Then you don't get the full effect of the cleaning solution
no, it will just be dilluted in the 15 gallon fuel tank and will be much less effective
B4 you replace fuel filer which a good size fill filer with purge and reconnect feed and return line then prime and Start engine let idyle and repeat lot easier
when i do purge on my 2000 golf tdi alh just little bit of fluid coming from pump return line .Any thoughts whats problem of this restriction
If you have got a mk4, have a look at my channel and see if there is anything that helps you there
Would you do this before or after replacing filter ?

Don't you have to pull the fuse on the fule pump to disable the fuel pump or you will wind up with diesel fuel all over the engine compartment.???

Yes certainly. I believe I have the same or similar engine in my Seat Ibiza FR. I'm about to do it soon myself.
@@dacman61 you mixed with diesel or run from only purge?
@@wentworthmiller5 I ended up mixing with diesel in my tank. I didn’t the process in the video.
Mustn't you remove the fuel tank fuse before starting the engine?
depends if its a mechanical lift pump, or electric fuel pump, I'm not sure in this case...
Has any one tried this with a 1.9d t4 wondering if I should take the fuel filter fuse out. Cheers
