VW UP very often "failed to start charge" with 3.3.005-3-g4f3f7688

[magicWF]

Hello.

after the OTA firmware update from 08.09.2025 I get very often the response "failed to start charge" when I will start charging. After a reboot of the OVMS the charging starts immediately.

`Last boot was 13684 second(s) ago

Perhaps someone has some idea.

Today I switched to OTA_O Image. I will observe it the next time.

Please test the current "edge" build, as that has a crucial bug fix for the VWUP T26 code producing frequent crashes and failures.

Installed the version 3.3.005-274-g795b0cee
But also with this version I have truble to start the charging:

How I can help to fix this?

[dexterbg]

Please do log level verbose v-vweup, then redo the set charge current & start charge commands and capture the log excerpt.

Reset the log level by log level info v-vweup afterwards to avoid excessive logging.

[magicWF]

Hier ein Logfile.
Zu erst hat das Starten des Ladens noch funktioniert. Dann habe ich das Laden wieder gestoppt. Beim zweiten Versuch das Laden zu starten, kamen dann Fehlermeldungen.

Der Stack overflow müsste jetzt behoben sein, bitte teste mal den aktuellen Edge-Build.

Wir haben jetzt zumindest schon mal die Crashes eliminiert, die nächste Frage ist nun, was bei der Ladesteuerung schief läuft.

@sharkcow Heiko, schau hier gerne mit rein.

[sharkcow]

Also was auffällt sind die häufigen Nachrichten zum OCU ring. Du hast die Original-OCU aber schon ausgebaut, oder?
Im letzten Log hast du auch immer den Strom geändert; kannst du mal versuchen, nur die Ladung zu starten ohne den Strom zu ändern? (Einen Strom von <6A kann der e-Up offiziell auch gar nicht...)

[magicWF]

Nein, die Original-OCU ist noch eingebaut und betriebsbereit. Nur der Zugang über die VW-App ist nicht mehr aktive.
Ist das ein Problem?
4A funktionieren wunderbar, war mir noch in der WeConnect-App von VW aufgefallen, dass man den Strom so niedrig drehen konnte.

[magicWF]

Hier ein Log, wo ich nur charge start / stop gemacht habe. Hier hat es ohne Probleme funktioniert.
Ich versuche nochmal das zu loggen, wenn er wieder in einem Zustand ist, wo er "failed to start charge" liefert.

Eingebaut darf sie bleiben, betriebsbereit laut unseren Anleitungen nicht:
https://docs.openvehicles.com/en/latest/components/vehicle_vweup/docs/index.html#using-both-connections

Probier's bitte mal mit deaktivierter OCU, vermutlich funkt die dazwischen.

Zum Deaktivieren der OCU am einfachsten Sicherung SD1 ziehen:
https://docs.openvehicles.com/en/latest/_images/IMG_8280.JPG

[Shr1mpling]

I have a similar issue with the newest edge version (but I haven't deactivated the OCU yet). I tried starting the climate control in the following log and I got a profile puffer overrun.
serial_20251226_175833.txt

[sharkcow]

It is not recommended to have both OVMS and the original OCU connected to the comfort CAN and active. We use the same ID as the OCU in OVMS, so this is bound to lead to problems. Until someone works out how to have a different ID for OVMS, you will have to pull the OCU fuse if you want to use OVMS write commands (charging & remote climate).

[magicWF]

I switched off the OCU.
@dexterbg / @sharkcow : Do you have some problems with the Service in the garage or with the TÜV, when the OCU is switched off?

Today I get the error "failed to start charging" again. After I pressed "stop charage" in the OVMS website and than "start charge" it works.
Here is the log:
