DIY How to Replace a 2.0 Tdi Injector CJAA

[@meirionrhys3786]

3 minutes in, just what I needed to figure out with the return line 😎

[@mariodesmo]

That scan tool makes all the difference. Nice little repair!

[@TestDontguess]

It sure does, it pays to spend the money

[@lacevvood1]

@@TestDontguess which model scanner would you recommend for a home diy mechanic? I have the same engine in my sportwagen

[@hayzeproductions7093]

Definately saving this video. All injectors are leaking on my 2009, plan to replace the seals o-rings and clean the tips as a first before replacing any. Autel should have a fuel prime feature because these cars have a tank pump and the high pressure pump. It is said that you should not crank the car like the old fashoned way, you should use the scanner to do the prime functions in the scanner.

Great help for me in replacing the #3 fuel injector on my 2011 VW Jetta 2.0 TDI

[@DarkAttack14]

I'm wondering if there's some sort of common theme, I'm getting my #3 injector on my 2012 passat (ckra) replaced by Volkswagen as soon as the part comes in. What's the mileage on your jetta tdi? I'm around 130k

[@larrystout2385]

@@DarkAttack14 I have 372000 miles on my Jetta, and since replacing the first injector the check engine light is coming on showing that the cars main computer needs to be updated. But because the car is so old the dealership doesn't want to waste time updating the computer... trying to get a guy who does aftermarket work to update it.

[@DarkAttack14]

@@larrystout2385 oh wow, I'm hoping I can get mine to make it to 370k! My old 2002 mk4 jetta diesel died with about 320k on the odometer and I'm trying to beat it! Hopefully they manage to get your ecu updated and in working order good luck

[@MAKPowderCoating]

For other DIY people, VCDS is a much more affordable scan tool for VW/Audi. Best $200 you'll spend on a tool if you own a vw or audi. Also you want to bleed the fuel system using VCDS. That scan tool may have that adaptation. It's imperative you bleed the fuel system as the high pressure fuel pump can fail if ran dry and generally causes about $6-8k in damage.

[@TestDontguess]

You must not understand how the diesel fuel system works the injector lines are after the HPFP no need to activate the low pressure pump cause none of the fuel feed lines have been disconnected. Injectors are bled by cracking the lines and turning it over so all the injectors are spitting fuel…. 🤦‍♂️🤦‍♂️ the HPFP isn’t going to get fed fuel unless the LPFP is feeding it…. The HPFP isn’t going to be pumping fuel unless the motor is turning over….

[@MAKPowderCoating]

@@TestDontguess I am aware how the system works. However ANY time that fuel system is opened VW recommends running a fuel system bleed procedure in-order to prevent premature HPFP wear. When the HPFP fails it sends metal shards through the entire fuel system. They replace everything fuel related from the pump to the injectors, tank, lines, etc. These CP4 pumps are very delicate compared to the CP3.

[@TestDontguess]

That is irrelevant to changing injectors….. like I explained above

[@MAKPowderCoating]

@@TestDontguess I didn’t write the manual. Take it up with a German engineer.

[@colin5064]

nice job oil the injector rubber o ring seal yes but why oil the copper washer seal? never heard of this why do you do this?

[@matmass01]

I KZbin lots of DIY's and i wanted to day good job sir!

[@jdeday]

How did you determine which injector had failed?

[@shaneleavy3351]

Any body ever get a leak from the seal on the injector plate ?

[@bigguy115-fq1hk]

I have that issue right now, unfortunately. Seems to be fairly common

[@roybm3124]

Yes

[@guytheguy18]

​@@bigguy115-fq1hk me too. I believe the o-rings need to be replaced on the fuel injectors

[@Qqqq-gf9ow]

My has that also, what would the leak be? Oil or diesel?

[@MoneyMarcMes]

Did you have any issues with the scan tool after you purchased it from amazon and registered it? I heard Autel disables the scanners purchased from amazon. Is that true?

[@TestDontguess]

Never had a issue with mine

[@JeremiahKingston-zu2nv]

How did you know which injector was bad?

[@BEFORETHEMHYPEBEASTS]

Is the taken out injector supposed to be wet all over its body like in this video or is this considered a leaking one?

[@hanspetterlunde3007]

What are the treads on that spesial tool. I have to make one. So i need too know the treads on fuel conector on top of the injector

[@muradkhan6787]

Excellent information keep it up ❤

[@lukeanderson5196]

What is the special tool you mentioned for removing the injector? I found a injector puller kit that says it works for my motor from ecs tuning but i am just wanting to make sure its the proper one before i buy it as the tool you screwed on looks different than the parts in the kit

[@Tyler-ts2ld]

He used a slide hammer. Nothing special. It’s generally not needed though.

Any idea how much cost to replace 2 injectors 2012 VOLKSWAGEN PASSAT SE BLUEMOTION TECH 1.6 TDI DIESEL 6 SPEED MANUAL Please 👏

[@dieselhead5891]

Actually 2.0 TDI get bosch injector right... How much Horsepower engine is this?

[@b.c.goldprospecting1724]

Looks like a pretty nice scan tool.

[@guytheguy18]

Thanks for the video but how did you line up the holding bracket and injector when you were putting it back in at 10:36? I'm struggling to place it back

[@TRXC8]

Did you figure it out? Having the same problem lining it up

[@robsonenduro3316]

nice, wonder what's the torque for these bolts under the plate though.

Where did u buy the new injector I want to do all of mine?

[@infinitibased]

Did injector 2 and 4 bounce up and down

[@longhuynh5249]

Very helpful, thank-you

[@robertnoton5005]

Where do I get the injection poor kit

[@adamstaff182]

Do you need the special puller tool?

[@TestDontguess]

I built my own

[@smiller1413]

Not necessarily. I used bailing twine looped around the injectors with a slop knot on the lower injector base side and a baler knot (a non-slip knot) on the top side leaving a loop up on top to clip a breaker bar or other tool through. Slip a breaker bar or a levering item through the upper loop and a deep well socket socket or the raised back potion of the cover to rest the breaker bar or tool upon and lift the injector out of it's seat by pulling upward on the twine. Just my 2 cents worth as my Master tech buddy gave me with the wrong VW puller this weekend...and I had to pull them myself. They are not too hard to lift upward, and some people can do it by hand.

[@Ulford]

How often do you drive this car?

[@thenfsoverclocker7143]

How to tell if injector is bad?

[@MrTeknown]

Values you saw in the last part of the video while engine was running are very high instead of being close to 0. Over 2 or 3 is not normal. Measure has to be with warm engine.

[@nickaxe771]

Is this the same engine as fitted to the T5 VW van...2015 2lt diesel.....been told the injectors can break off inside the head getting them off/out....is this correct.

[@smiller1413]

It sure seems highly unlikely.

[@TheRwdyAudi]

What is that tool you used to remove the injector I'm need to do this very same job

[@TestDontguess]

It’s a small slide hammer but I made my own tool to fit on the injector

[@Buthos]

@@TestDontguess Any chance you remember the thread size for the injector so I can make my own tool too?

[@joelscoffield9770]

I cut an old injection line off an ALH and welded the cap to a piece of threaded rod with a section of pipe to fashion my own slide hammer

Do I need vcds if I am just taking the injectors out for cleaning them?

[@smiller1413]

Not if you pull them and reinstall them in the exact same locations. Mark them all 1 to 4 before removing.

[@danhambrick6331]

That didn't seem like that bad of a job Jerry..

[@hayzeproductions7093]

11:20 those 2 nuts under the rotating plate dont require a specific torque spec do they? I was having problems with a ton of blowby going out of the rubber seals, was a bunch of soot all around the injectors and got bad where oil was also pushing out as well. unbolted those plates turned them counter clock wise, and made 1/2 turns tight to each injector. The nuts for the injectors weren't completely loose but loose enough for me to make the decision on tightening down that much.

[@keyboardheroism]

10nm

[@hayzeproductions7093]

@@keyboardheroism thank you

[@keyboardheroism]

The hp line that goes from the rail to the injector is 25nm. It's important not to over torque these. I use a 17mm combo wrench with a nut and bolt secured on the box end and then I put my 3/8 torque wrench to that. An off set crows foot will work as well. Take care not to touch the injector return stem as you tighten. Also you shouldn't Crack the injector lines on any hp common rail setup. The system makes 330bar (4800psi) at idle. It's dangerous and unnecessary. Some air bubbles won't hurt these injectors. They are stout. You must do the fuel priming procedure to rid of any potential air bubbles in the hp injection pump, especially on the stock cp4.1 pump.

[@hayzeproductions7093]

@@keyboardheroism thanks for insight on this, I havent touched the fittings on the high pressure side dont feel the need to because they are not the ones leaking. Currently keep finding oil nesting on the top of the valve cover, I always have to take a rag and tuck it between the return fittings and cover to soak up the oil. Believed the issue is coming from the seals on the injector plates. Issue i have is i dont want to take the entire fuel system apart just to clean or replace the plate seals. Thats just far too much unnecessary work.

[@keyboardheroism]

Yeah mine were leaking. The injector has to come out. You'll need new inj body oring and copper crush seal. Pain in the ass. But it stopped leaking.

[@joesaiditstrue]

looked like a relatively easy cheap repair until you busted out the expensive computer tool, recode injector :( why VW, WHY do they gotta do this

[@TheToastedGamer]

You can find vdcs and cable for cheap:) and its not too bad to learn. Many guides online:-)

You’re right. It’s just the injectors. Like the title says

You should replace all the injector cover plates while doing this job. 10 bucks a piece....no reason not to.
