How to service Eberspacher Airtronic D2 Diesel heater maintenance, repair, Chinese heater is identic 

This is the most detailed with great close-up video shots of heater maintenance I’ve seen on YT. Thanks a lot for the effort of making the video.

This is hands down the best video that I've seen so far pertaining to Espar maintenance and diagnosis. I was able to completely disassemble it and service the entire unit with confidence because of your instructions. I reinstalled it and it works great! I also changed the fuel filter near the pump. Thank you so much. This gives me the confidence to continue lifelong learning about my equipment and how to maintain it. Edward

Hi, I'd like to thank you for you video. My D2 was just smoking. Your video showed me how easy it was to disassemble and my problem was identical to this one. The breather hole was gummed up and poking a pick from the inside where the igniter and screen go wouldn't clear it enough. A little bit of time, a new gasket and a can of brake cleaner later my D2 is running like new.

Huh. This gave me a good insight how Eberpacher works. I have a old factory fitted on my car that just smokes and shuts down. I hear the pump "tick tick noise" so i think its clogged. Thanks

Thanks for taking the time to do such a great video for us. I've had my espar running only ~6mo with regularly screen servicing. I'll use your tutorial to go through everything.

Great vid, I paid out for a Maxspeedingrod 2kw obviously a little more than you get on the bay. From day one there was a loud burner sound like a buzzing or whine, this apparent noise could be heard through the air intake/exhaust. I pulled it apart just like this vid (I have done many before) and considering it was a known brand I was shocked the gasket was missing on the burner chamber and the burner itself had been welded offset so the flame was firing against the edge of tube. If you turned the burner upside down and sat it on the table the burner tube was offset about 3 degrees off. Now I knew my problem, but this was dangerous for me as exhaust gasses could have leaked out. I sent a huge complaint to them as this was clearly a return at some point and then resold. So still waiting for a reply and it's thanks to this vid and the others I had worked on that convinced me that this was a faulty unit 100%.

Really good content. Thanks for sharing the information. I've watched a few of your eberspacher videos and I think I can service my own unit now. Many thanks

Good video. Any idea when staring it sounds like a plane taking off?

Great video. My Espar S2 D2 L is blowing fumes during shutdown and I've done all the installation fixes, sent unit to Espar service and said everthing was fine, got it back and it seemed good for the first two weeks and then started smelling fumes again from the cabin vent and it got stronger and stronger indicating maybe a seal was breaking more loose. It's most strongest during shutdown maybe 30 seconds before it's about finish cooldown and stop. I took it apart and can see stains that show it's leaking at the glow plug. I have a hard time believing that air can't easily leak from the glow plug gasket or especially the fuel line gasket as the top of it is only mating with the chamber gasket. I don't know how much pressure the blower chamber creates but I feel like it's fairly easy for air to get past that part of the fuel line gasket when it's just two rubbers pressing together. The new Espar uses rubber gaskets for the blower chamber not the flat metal with some coating you mentioned. Also the mounting gasket is most suspect at the air intake and fuel line side as the fumes can just flow right up through that gap around the intake. I 'm not sure if the cabin vent will create a vacuum sucking fumes from outside up or if there is possitive pressure pushing heated air out, I'm guessin maybe a vacuum, what do you think? I'm waiting for parts and going to see if my maintenance and repair will fix it as I'm afraid sending it back they will not do a good enough job again, I don't think they even replaced my cracked burer gasket. The threading on the glow plug always seems to get dirty, I suppose it doesn't created a seal? Only seals at the top tapered end of the plug to the hole, is that correct?

Thank you for the detailed video and excellent info.

Felicitări pentru acest video explicit, o lucrare făcută cu rabdare într-un mod profesionist. Am același model, aș vrea să știu ce setări pot să fac în menu, am intrat cu apăsare lungă pe săgeti, pare că la linia "14" se face reset, dar celelalte linii 1_1, 1_2, 1-3 etc, nu știu ce reprezintă. Mulțumesc!

Thanks

Excellent service

Thank you for useful videos.

super informativ si cuprinzator tutorial . multumesc. as dori sa te intreb,care este rolul gaurii acelea mici de pe corpul camerii de ardere in zona unde se infileteaza bujia? am mai multe ipoteze in cap ,dar nu pot sa mi dau seama fiindca ma gandesc ca marea majoritate a aerului necesar pt ardere vine prin fantele alea din capul camerei de ardere. multumesc mult!

So the heater has no intake air filter? I think low voltage is more likely the problem, the glow plug is not hot enough if the voltage runs low.

Thanks!

Salutare! Felicitări pentru inițiativă și clipurile din canal! Și D2-ul meu a ajuns la pragul de 1500 ore. Încă se comportă foarte bine, nu am avut probleme. A fost cumpărat și montat de nou în noiembrie 2021. Am început documentarea și va urma să comand piesele de schimb pentru 2000h. Mă voi ocupa personal de schimbul lor. Este nevoie de diagnoză neapărat? Este nevoie să îl programez într-un fel după schimbul pieselor sau pot face din meniul de workshop din EasyStart Pro? Mulțumesc mult pentru tot! Spor în toate!

I can’t understand what cleaner u used. Did I hear brake clean?

My espar bar worked fine for about 4 years then it starting smoking then stopped I watched a few videos (not yours) then I rebuilt it new gaskets cleaned every new glow pin new screen It worked great about a week did same thing Carboned up so I cleaned replaced gaskets again and it stopped again last night which is about 10 days later again I looked up the exhaust pipe with scope its full of carbon again any ideas what else to try

Hola mi D2 al prender me dice n51. Que puede ser ?? gracias

If it’s really coked up you will struggle getting the fuel vaporiser/screen out. I ended up with a strip down as in this excellent video

But if it is put back in the same environment, will it not just clog up again?

👍

can I used Diesel Fuel, Supplement/Cetane Boost in my heater fuel to make it burn cleaner , keep it cleaner?

Thanks for the very informative videos sir. My D2 after 4 years of work had the same smoking issues. I took it apart, cleaned as much as I could the burning chambers along with the breathing whole. Replaced both gaskets and the plug screen, installed it back on. It works for like 5-8 min at a high speed, then suddenly it shuts off, while the body is overheating. Also the blowing fan runs at various speeds. I don't know what could be the problem 😕 Do you have something in mind about why is that ...? 🤔

Hello. What type of pump is required to run the Hydronic D2 24V version? What programmer did you use? thanks for the answers regards

Hello. here is the color of the cables coming from the heating 1 blue 1 yellow 1 red 1 brown 1 purple in your answer there is no yellow. I do not know the color of the cables for the easystart select command. can you help me, thanks

Where is your shop ? I need to repair mine now :))

Hello. I found that the unit, when placed on the test bench, was controlled by A digital eberspaecher order. I have the same heater (D4) controlled by a mini regulator and I would like to replace it By this digital command. Can you give me the cable color match? cordially

After taking mine out for for service I cant get mine to start or get the fan to even start. Just wondering what I did wrong. All plugs are in the proper places.

yes, there is the mention H-kit!

Filip is that you?

What is different between d2 and d4? Mine is airtronics

hello, how can we contact you?
