CBEA/CJAA DPF info

[wonneber]

Thanks, Always great info from OH. Much appreciated!

All, does anyone know the cost if every thing is needed?

I hope my 2014 TDI CJAA is not involved

You do not want to know.....

 

[wonneber]

You do not want to know.....

The only thing I know is the only thing cheap is paychecks

 

[oilhammer]

All the CJAAs and CBEAs have this issue. All the replacement parts are the same. Save of course for the untouched 2009s, but I'd lay money there are not any of those left.

You can certainly try to clean the EGR tube, but there is no good way of checking how good you did, since the little mesh screen is not easily seen. Maybe a scope camera will get in there.

New here with a dpf issue. 2012 sportwagen 6 speed 123K. Ive read this thread and surmise I need to replace DPF and associated parts.

Using a schwaben (foxwell) scanner i have:
code 09315 which is P2463 - DPF
code 00310 which is P0310 - O2 sensor
code 01592 which comes up as either air quality sensor or Throttle Actuator (Scanner says Throttle actuator control)

Regen light is flashing yellow and the DPF light is on as well. It appears the engine is in limp mode as the tach will not go above 3K and 2nd and 3rd gear are sluggish at best. Looks like soot in the tailpipe.

Im thinking DPF is cracked and needs to be replaced? Oilhammer can you confirm or enlighten me. Your explanations have been very helpful, thank you!

Swipe your finger on the tailpipe, if theres soot, its cracked. No clean for a cracked dpf. You can replace it or delete it.

I had my t-stat replaced bc I noticed it was not closing as it should. The OEM CJAA PN: 03L 121 111 AC cost $134, and the labor was $560 in Oct 2024 at a well known shop south of BOS.

And on the Cjaa it took me 1000 plus miles to achieve all Parameters , I was losing hope after changing a glow plug for a while

I didn’t take the vw fix Or cash so it’s still cheating

Hello,
I’m new to this forum and looking for thermostat problem advice on EA288 Jetta engine.
had low temperature and started into replacing thermostat housing. Can’t find any information on this setup. Could I physically replace the thermostats as I understand there are two different thermostats. Or is it possibly the warm up sensor that controls the valve on the water pump. I’m trying to get my Boxeer conversion on 82 Westfalia back on the road. Thanks

Does the water pump installed in your engine have the clutched pully? Most people are replacing the water pump a more reliable because it has less moving parts kind of part. All of the timing belts I do never include that kind of pump.

I believe that EA288 engine has the thermostat housing at the front of the engine, buried behind a pile of other stuff.
The thermostat comes as part of an entire four (maybe five?) inlet/outlet housing assembly, so a LOT of stuff has to be moved out of the way to gain enough access to get at it.

I've replaced a couple - just takes time; but both times it's solved the low operating temp issue the owner had with the car; and it is definitely something you want to address.

My question or dilemma is where or how does this thermostat attach to backside of the water pump. Does water pump have to be pulled out to remove housing? Any diagrams or details of this setup. I’ve searched the internet & found very little or helpful information. Can the thermostat or thermostats be replaced without replacing the entire thermostat housing??

 

[oilhammer]

This thread isn't about the CVCA or CRUA engines, nor their thermostats.

 

[italianmam66]

Then what do you discuss. Hey just trying to put my question out there. You replied the first time around. I don’t get it…do you not share experiences or information?!?!

The OP is posting that this thread is about the DPF issues with the CJAA/CBEA and not the thermostat.

There is a form section for your car type and you can post a new thread with your issue and people can help you out.

Sorry but you are speaking in another language.
EA288 engine was a popular power plant. Guess I’ll try some other source or find a manual for that engine. A 2015 Jetta TDI engine. Why is this a mystery or misinformation about what I thought was common knowledge. Replacing a thermostat in a diesel engine.

 

[P2B]

It isn't. Just posted in the wrong place.

 

[borninabus]

there is a dedicated section (a whole forum) for your car and engine where discussion is focused on the one-year-only 2015 TDIs. you should search for the information you seek there or start a thread there.

this thread--which is a part of a general TDI knowledge forum--is focused on the chronic DPF problems of the previous generation TDI engines.

2015 Jetta - this is where you want to post/ask about your thermostat issues:

VW MKVI-A6 Jetta Sedan (~ 2011+)

Discussions area for the MkVI (2011+) Jetta sedan. This model was originally codenamed NCS (New Compact Sedan).

Not here it wasn't. As others have stated, for the North American market, it was ONLY used for the 2015 model year. That's it. And the topic of THIS THREAD is not about that engine at all. Speaking English. Cannot make it any clearer. This thread is about 2009-2014 CJAA and CBEA engines, and the DPF issue they have. That's it. Not complicated.


1.4-2.0 litre EA288: 3&4 cylinder
[edit]
The EA288 engine family is based on the EA189 engine family.[3] EA288 diesel shares displacement, bore pitch, stroke and bore ratio with the EA189 and the new EA211 gasoline engines.[4] It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)),[5][6][7] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system, cylinder pressure control, a modular close-coupled after treatment system that includes a flow-through catalyst followed by a wall-flow diesel particulate filter (DPF). Euro 6 and US Tier 2 emission compliance is achieved via NOx adsorber-based system for smaller size vehicles or urea-SCR system for larger vehicles. Other features included low-friction bearings for the camshaft and balancer shafts, piston rings that have less pre-tension, a two-stage oil pump with volumetric flow control.[8][9]

The engine's displacements were 1.4 litres (3 cylinders), 1.6 litres (4 cylinders) and 2.0 litres (4 cylinders),[10][11] with power output between 66 and 176 kW.[12]

READ THIS PART HERE:

The engine was to be first used in 2015 model years of Volkswagen Golf, Volkswagen Beetle, Volkswagen Passat, and Volkswagen Jetta

You essentially "hijacked" a thread for your own situation that wasn't about the topic the original poster created. It's better to start your own thread and if you need to reference something in another thread, to link that in your post. That's what everyone is trying to say to you.

Capisce?

Would somebody be able to help me find what I need to reset in the VCDS after replacing my DPF?
2013 golf TDI

 

[oilhammer]

VCDS walks you through it:

Adaptation of Carbon Mass (after DPF Replacement)
Prerequisites:

• Ignition ON
• Engine OFF

[Security Access -16]
Enter the code shown in the VCDS pop-up balloon for "Adaptation Enabling"
[Do It!]
[Adaptation - 10]
From the pulldown menu, select the entry for "Carbon Mass (DPF Replacement)" or "[*IDE00275*] Particle filter initialization".

• If those channels are not available look for [*IDE07903*] Adaptation of ash mass.

Save a new value of 1 to reset the learned Carbon Mass. It's normal for that value to automatically change to 0 after it has been successfully saved. Check and clear fault codes to make sure none are present.

So, more detail:

Key On, engine Off, plug VCDS in, go to the Engine, then once that screen comes up, click on the Security Access tab, then a pop up box will come up that prompts you to enter a code to enable Adaptations.... enter that code, then come back out to the Engine main screen, then go to Adaptations, and in there, pull down the menu and click on the one that says "DPF replacement". Once in there, a pop up box will prompt you to TEST/SAVE a 1 or 0 then you back out, back out of the Engine, shut the key off, and you're done.

while they may have some misspelled words and lack some punctuation it is by no means hard to figure out what they meant. try posting your question in the proper section.

it is a forum, no one is singling you out. like every forum i've ever been a member of there are specific subforums. this is designed to prevent confusion and make future reference to old discussions easy to find. while your question could easily be answered in the wrong sub category it may confuse someone in the future and provide them with false imformation. the amount of time we've spent explaining this to you could have been spent answering your question in the proper category if you had EASILY just posted there instead.
