How to use diesel purge VW TDI engine (Audi TDI similar)

How to use diesel purge on a TDI engine. A 2006 is shown but this procedure applies to similar engines. Watch • How to DIY Lubro Moly ... if you have the older style fuel filter. See www.myturbodiesel.com for more

[@danielleewild]

I carried out this process on my Skoda octavia 2.0 TDI Vrs, I found this video really helpful, only thing I did different I just doubled back one pipe on itself on the fuel filter. Afterwards the vehicle was more responsive

[@brookes0508]

For everyone that has asked or questioned bypassing the cars existing fuel tank to do this yes it will still clean, the reason why it is done this way is 1 to return and debris back to the temporary fuel can secondly to give the full concentration of the product to the injection pump and injectors. Filling the filter canister will return excess product back to the tank. Depending on how serious you are wanting to clean determines what route you go mind you the most effective method is the one shown in this video.

[@danieless4009]

I started watching a injector cleaning video then we got some cat removing instruction too. glad you left it in. made my day. my cat would do something like that.

[@TheKeithuk]

Another good video Chitty, the forum has gone crap since you sold it, the TDI Wiki doesn't show now

[@ukaszzywicki9563]

When i was cleaning my injectors in audi a4 1.9 PD i did pull fuel pump fuse so i did not have to bypass fuel pipes...

[@timsonner]

Thanks for the tutorial; it worked great. Can’t wait to run another can through!

[@albarghouthy]

Thanks for the video it's really helpful. But I would suggest that you change the fuel filter before using the purge step, this way you don't have to prime the fuel pumps after changing the fuel filter (in cases where it's needed which can be a hassle) you are giving the pumps enough time to fill the filter and lines with fuel and purge out air. overall I like your videos. cheers

[@HuVoTNL]

Edge, I also have a 2009 and you should have feed and return from the tank and they should be looped together and feed and return from the injectors rail which you connect to purge jar..

[@hdudic]

Thanks for your reply. On US models, the high pressure pump is on the left. I figured out that there is a pressure sensor before the high pressure pump, which will not allow the car to start unless there is sufficient pressure coming from low pressure pump. How did you bypass this sensor?

[@dogman_]

In my mk7 I just pumped all the diesel out of the fuel filter housing, put the new filter in and poured Diesel Purge in.

[@shaunwhitaker8078]

Worked a treat, cheers!

[@jemmace2586]

Thanks for the video, I'll remember the process if ever my car (rabbit 1.9tdi BXE)gives me fuel related grief.. its smoking.. a little, when I accelerate excessively but I'm sure that's to be expected.

[@SuperElectroAddict]

hey, what type of tubing should i use for the lines? i picked up some vinyl tubing but i could foresee this melting perhaps. any suggestions?

[@anghelalexandru9076]

hi! can you tell me where i can find the connector to connect the two diesel pipes you disconnected. thank you

[@Vcoldduck]

what size lines were you using and where did you find them

[@yurem1552]

So that works to clean the fuil injectors for TDI?

[@umby06]

did you notice how the auxiliary tensioner needs changing or something in the belt drive is oscillating

[@Motor-City-Mike]

just curious, if there was concern over using a plastic container during the cleaning, why was plastic line and a plastic in line filter used?

[@elshadajdooel4367]

Between libro moly purge and lique moly purge which ia beter for injectors?

[@edge1307]

Hi, Can you please do another version or add an addendum using diesel purge on a 2009 VW Jetta TDIi (CBEA common rail) as my engine does not have the three stainless steel fuel lines as shown in this video. My fuel filter housing has the four hoses and also the Torx bleeder screw. It uses the "'wide mouth" 434A style fuel filter. Thanks

[@Vcoldduck]

you said the lines on the filter housing were pluged up. Are they pluged or was that a hose nipple I saw? Flow thru

[@danielwinfield350]

Hey I have a 2004 vw Passat gls tdi 2.0 I was wondering how to change the fuel injectors

[@MrChrisIncredible]

I have read that the 06 Jetta also has a fuel pump at the fuel tank that could cause problems during this procedure. Is that why you combined those two hoses off the fuel filter canister with a coupler?

[@Richard_L_Y]

Use two paper filters (especially if you are going to re-use the excess left over in the filter compartment or tank) and connect them directly into the hoses at the filter; then you only need two plastic hose lengths; use the (5/16" / 8mm) plastic join / splice connector to directly connect the tank to filter and return feed hoses. I've still nowhere seen an example (or any other info) which definitively shows the the feed and return direction for a VAG 8P1! (but it's easy to see and work out when you connect and start (if you've got the filters the wrong direction (just a bit more messy if it's the wrong way around). Suck some purge fluid into the flow filter first before you connect that if you want to avoid drawing air and possible stall (just be careful not to get it any further it's not good for you). A plastic container with two holes drilled in the cap for the plastic hoses works well and keeps the hoses in place (if hose O/D is e.g. 11mm use a 10.5 drill bit if you can; don't worry most plastic won't melt even though it gets fairly hot) It's easy! However it made no noticeable difference to the performance of an 2006 8P1 Audi A3 1.9TDi at 100k miles; but the paper filter clearly showed it had filtered something. Some say this shouldn't be done on a common rail?

[@Richard_L_Y]

@Read A book Grow a brian moran.

[@mannys9130]

You don't put it in the tank, you don't put it in the filter. You do it just like he showed, with a jar and fuel lines. Burn up 2 cans of purge at varying engine speeds. Just before you run out, stop the engine and put everything back together. Then replace the fuel filters. You CAN prime a fuel filter with purge, but it won't clean like it needs to because the filter will fill with diesel and the purge will get flushed to the tank. Just pouring it into the tank isn't strong enough.

[@themayomanentertainment4335]

I have a no start issue, and I had the same issue over a month ago. Had the car at a shop and the mechanic said something to the effect of purging the lines and now the car is doing it aga and won't start. How can I fix it and what is causing this issue??

[@l07smitty]

When i went to the "push orange cat away" step, it wasnt there. -Am i missing parts from my purge kit?

[@jerryaguilera8019]

LOL

[@Elaba_]

I just saw a video of a guy doing a DIY tire removal from the rim. I got distracted by the chickens on the backside. And now this video. Lol.

[@dankcorey2424]

Could you just pull the in tank lift pump fuse out?

[@ernetmaroc6560]

Does this method work with renaut clio 4 DCI with fuel pump in the tank?

[@paulwary]

Any advantage doing this over adding to fuel tank? Seems it would be better to let a chemical work for a much longer time, and at higher flow rates, albeit at a lower concentration.

[@alennuri]

Hi i use dis method on my Altea 1.9 105 TDI in december and in february start smoking again.enyone?

[@michaeljdburns]

Is it possible to just fill the fuel filter housing with the purge instead of removing all the lines?

[@klitoni1]

I have the diesel with cooler system how can i do that?

[@sivucit]

hi i asssume you are doing this purge on low pressure side and not high pressue side of fuel system, is that right

[@kedardesai3469]

hi , I have a vw polo in India . our cars do not have a return to the tank . can i just fill up the fuel filter with diesel purge and run the engine and then put in a new filter ? Thanks .

[@manuelmorales9423]

hello ablo not English for this question use the google translator. I'm a mechanic and I have no experience Jetta TDI. This will change the engine to a 2010 Jetta TDI diesel question is what I purged with LLBRO MOLY DIESEL PURGE not only deconetan in llectore also explained in this video How to use VW TDI diesel engine purge (like Audi TDI) I'm so stressed out that doubt thanks

[@reddragon81088]

What size hose did you use?

[@94vettelover2]

What was the point of this?Did you do this to clean the fuel rail or to purge the air out the the rail?Trying to learn as much as i can about these diesels & you seem to know these pretty well.Thanks in advance for the answer.

[@osamaalsayd6519]

thanks Mr jimmo

[@crunch805]

Can you show how to do this on a 2014 Audi A6 3.0L TDI?

[@Corsa15DT]

Not a problem running the engine on 100% additive? After all it says on the can to put it on a full reservoir.

[@94meriks]

haha most awesome cat ever! Sitting on the engine and purrs :D

[@gasousman]

nice kitty. love the fact that you wore gloves. too many people are giving themselves cancer you know.

[@ahokie]

Great vid. thank you

[@Wiliuz]

Ive done exactly like in the video. After running the engine for 2 mins, it died looked like ran out of fuel. Purge was bubling in a jar. Took a while to get it started again. Not sure what happened

[@PapiQaz]

Same, couldn't get it to work :(

[@Str8Rippin93]

does anybody know where he got the male connector from. I'm not sure which one? also is he using 3/8 tubing??. please help

[@marek196c]

ebay, or any automotive store, if you tell them that you need male to male connector and fuel line for X car they will help you out. also often can you find diameter wrote on your fuel lines.

[@shanecall]

In another video on a MK4, it was 5/16 connector and 1/4 tube. kzbin.info/www/bejne/n6LCi3qeZrB4m8U

[@davidbenjamin9509]

is the Top Hose+ rail the feed to the injectors and the bottom the return?

[@jimmomechanics7347]

l_l_lAdidasl_l_l its not about the top or the lines down/under. its about the lines from the fuel filter. follow them! the one who had an arrow to the engine is the inline. the arrow back is the return. so follow the arrows. u can find them on the filter

[@indian2003]

Is this a PD engine or a common rail?

[@blueneet84]

I LOL'd at the cat!

[@rjrobbins2]

I have a 2012 Jetta TDI and I accidentally put a few gallons of gasoline in it one night. I syphoned out the gas and put 5 gallons of diesel in it and replaced the fuel filter and filled the fuel filter canister with fuel (thank you for the videos which made it easier). Then, the battery ended up being completely dead. I bought a replacement today and while it cranks, it wont start. Do you think it is the lines? I was hoping I wouldnt have to do this as I am not a car guy. Also, it has been sitting for about 5 months now since the gas incident but all the repairs have been within the last 2 weeks.

[@johndavies4644]

Randy J Robbins is she running

[@uGoGop]

Purge the air and it will start

[@nazanin6632]

I still don't understand how this works. The engine won't start without low pressure fuel being pumped. I would like to know how your engine is running. I was only able to do this two types: The VE pump type (ALH tdi's) and the CR TDIs (09+ I think) that have a pump in the engine bay. I was not able to start a PD engine with this method because as far as I know the PD injectors can't suck in the fuel like the VE pumps. Can someone explain?

[@agt155]

PD engines have a cam-powered supply pump to provide fuel to the injectors. It's called a tandem pump because it is both a fuel and vacuum pump.

[@JohnLolasDad]

The diesel purge is clear, diesel is yellow. I noticed the diesel purge turned a diesel color upon start up so the easiest way is to drain the canister when changing the filter and before installing a new filter fill the canister with the diesel purge and then you do not have any fuel lines to disconnect. It will still clean the injectors doing it this way instead of the way shown in the video and in less time also. By less time I mean less time in being under the hood disconnecting hoses needlessly and then having to hook them up again as well as not having any possible leaks form the lines form them being disconnected in the first place.

[@navisolim]

John F yeah but the concentration of the purge is going to be smaller because its constantly mixing with fresh diesel from the fuel tank...that way is better then just putting the purge into the tank but if you do it like in the video its going to have bigger impact

[@RobinGWakker]

Agreed, just run the engine for 30 seconds for the solution to reach the injectors, shut off the engine, let soak for 20 minutes or so and run the car for a good 30 minutes driving around on highway speeds. The other thing i do before hand is decarbing the EGR valve to help smoothen things out. Works great.

[@PlayJewel]

John F How to drain the fuel filter canister? Can i just soak some tissues to get rid of whats inside?

[@besnikbajrami9240]

did this disel purge demage the PD injectors?

[@theturk8884]

No I have audi a 3 I did 3 times my car very good now jumping like a horse trust me very good for car nothing harm

[@vidsupercharged1622]

I can hear the cat "purr" !

[@jpb318]

Cat inclusion for the win! haha

[@mannys9130]

No not a problem. This is how you do it.

[@christophers1247]

this is just a cleaning product for the injectors/fuel rail and pressure system you dont have to do this at any point as long as you change your fuel filter regularly or are experiancing problems with your fuel system. these fuel systems on vw engines are very reliable unless they are expossed to dirty fuel.

[@brandtinofortune929]

Fantastic thank you

[@pravdasircone1691]

Could u just prime the fuel filter with diesel purge when replacing the diesel filter?

[@damianbreedt9345]

You can

[@zachgold8499]

What plastic connection were you using to join pipes together

[@kylecline]

Did you ever come across the answer to this?

[@uGoGop]

It is 8mm vacuum plastic connector. You can use a piece of small metal tubing called "NIPPLE" at plumbing supply or lamp tubing.

[@davidbenjamin9509]

Doing this will do what exactly.? Thanks

[@ttaallal]

I have 2012 Jetta TDI. Wont start. The dealer said all lines are clogged up with metal stuff because the fuel pump is messed up. they also said I need fuel lines and injectors. they want to charge me $5000 to fix it. Please help..

[@ttaallal]

I think I know how to change the injectors myself (I looked at other videos ) but I am afraid I will run into computer problem and/or resetting the system and I do not have the scan tool. Do you think changing the injectors is as simple as taking the old ones off and putting in the new ones? Thanks. How would I know which ones are bad instead of changing all of them?

[@igorsirbu1221]

same problem here. 2011 Jetta TDI CJAA with exact same failure. Was wondering what is the best way to clean up all the fuel lines when the car doesn't start? do I need to remove them all or there is another way? thank you

[@overand]

That's definitely not going to help. It sounds like Talal has a high pressure fuel pump failure. Google "HPFP Failure." The fix for this involves taking all of the fuel lines out, emptying the fuel tank, and cleaning out the metal bits in the tank, the lines, the sensors, the pumps, the injectors, PLUS replacing the failed HPFP and any other failed parts. It's a MAJOR repair.

[@cortinatim1]

Overand Exactly. The metal is coming from somewhere and 99% of the time it's the high pressure fuel pump. A waste of time and money if you don't fix that.

[@Corsa15DT]

purrs like a diesel ;)

[@iplaybose]

wouldnt it be easier to do a full refuel with diesel and then dump the cleaner in the fuel ?

[@stardust6385]

No, this product is supposed to be used pure through the injectors to maximize the cleaning effect.

[@myturbodieseld0tcom]

No, it should have come with a box of dry dog food. Rattle the box and the cat will come to you.

[@123fuhfrtgfh]

I accidentally put the orange cat in the jar, is that bad?

[@mannys9130]

You can prime the filter with purge, but it won't clean. All the purge will be flushed back through the return line and dump into the fuel tank where it will be diluted way too much to work properly.

[@aygwm]

I prefer adding this stuff to a fuel filter as I am changing it, putting the hoses directly into the diesel purge bottle can introduce dirt into the fuel system.

[@SAM-zt2uy]

I was about to turn off because my engines the older pre PD...... then a cat appeared 🐈

[@curtishagen6840]

Hahahahahaha push the cat away

[@stuartcox5194]

Why not just add to the fuel ⛽ tank?

[@Liveforeever]

It's more concentrated like this without dilluting with diesel so it's just cleaning and cleaning until it runs out.

[@KESYL1]

Wszystko fajnie, tylko po co.

[@mannys9130]

Nope, not the right way to do it.
