Thanks! Fixed VW Crafter original D5WS with this method. Grinded hole with carbide burr as it seemed much safer way to me. I had intermid working blower. Tought first that it was blower motor as bearings were totally worn out from it, but new blower did not help even it definetly needed to be changed also.

Thank you very much for this tutorial !
I was able to save my D4WS !
My welds weren't visually damaged like yours, so I didn't really believe it, but it worked !
The solders are complicated because of the residual resin which interferes with the heating of the original solder and the addition of tin.
To close I filled with a two-component resin for electrical junction boxes. Then I placed a large metal washer and metal tape.

Thank you for this. I am very grateful for your video. I have error 30 and 31 on mine now erratically. Its from 2010. I will try this fix.

If you want to drill a hole without a center because it's dangerous. First dril a hole In a bit of wood with the centers en then glue or clamb that hole on your work and make a stop on the holesaw

Hello, do you know anything about error 71 and 17? I can see that it is related to the temperature sensor, i tried measuring the resistance on the sensor and that reads okay. I tried shorting the wires to the sensor like the manual says to do, but that didnt change anything either. I originaly had the error 31 and used you video to fix it, but now i get the error 71 and 17. I read in the manual that to test the controller for the heater i would need the diagnostic tool you use in this video but i dont have access to one. I hope you have an idea for a solution.

Buna ziua! Am o unitate Eberspacher Hidronic D5WS. Ma puteti ajuta cu service ul? Nu porneste decat ventilatia in masina si pompa electrica de circulare apa. Unitatea nu arde motorina.

Buna ziua, pe un Viano 2009 alerta din logurile masinii este: “component a6m1(combustion air blower) does not function properly “. Credeti ca as mai putea cerifica ceva inainte de a aplica procedura descrisa din video? Multumesc anticipat pentru eventualele raspunsuri si efortul descrierii problemei.

Salut, vad ca esti din cluj, am exact aceeasi problema la un d5ws, ba merge ba nu merge, eroare 31. Crezi ca m-ai putea ajuta cu o manevra de genu asta ? daca il aduc demontat bineinteles.

Thanks for sharing this. I had error code CPM-1001 Combustion fan. Signal too high" on my 2010 Volvo V50 which has CAN-controlled Eber D5WS. I also had bad soldering on my PCB but it didn't fix the problem and replaced the old fan. My problem got fixed when I detached the PCB from case and isolated the PCB with some electrical tape and not attaching the PCB screws. Then the grounding comes only via wire. Hope this info helps someone else.

What type of sealant do you recomand to seal the hole?

Salutare, am probleme cu un Eberspächer hydronic II D5Z-H de pe Toyota Auris 2008. Nu da nici un semn de viață. Va pot contacta la un nr de tel?

[farkasalex-hmvm]

Salut, am un eberspacher d5wz de pe un sharan! As putea sa il pornesc fara masina? Adica fara calculatorul masinii? Ma poti ajuta cu o diagrama eventual? Vreau sa il montez pe un focus.... mulțumesc anticipat

Salutare ! Acel ventilator functioneaza la 12v sau la 8.4v cum scrie pe el ? Multumesc !

You're working on a remanufactured Eberspacher D4WSC controller where a capacitor has leaked, and its acid shorted the board. One node seems burnt but might still be repairable. You're asking if anyone has a schematic or at least a good photo of the board for reference.
