OK, you wrote "during charging". But are you certain the values are
those for the main battery, or can they possibly be for the DC
converter…?<br>

was the charger actually working, i.e. charge in progress? If not,
maybe it goes asleep as soon as the 12V aux battery is topped off,
and another ignition state change simply reactivates the topping
off cycle.<br>

Hi guys,<br>
<br>
Question for the CAN and ECU experts:<br>
<br>
I am logging into the battery charger ECU on my eUp via the
extended diag session code. Otherwise I get 7F as reply. <br>
<br>
I am interested in the power efficiency (pe) and power loss (pl)
values.<br>
<br>
It seems though as they have another timeout than the ext diag
session as I am polling it every 5 seconds. So ext diag is
"always on". <br>
<br>
But after 20 minutes during charging the values change from the
realistic ones to pe=100% and pl=0. To get the real values back
I have to unlock the car and turn the ignition. Then I can turn
off and lock the car again. <br>
<br>
Now to the question: Is this behaviour somehow known from other
vehicles as well or can it be an error in my code not sending
the ext diag msg correctly?<br>
<br>
Although when I dont send it at all I dont get even a value for
pe and pl, just the 7F error msg. <br>
<br>
So do you think it is possible to get those values for longer
than 20 mins without having to turn the ignition? Or am I out of
luck here as it seems to be some VW specific thing...<br>
<br>
thx<br>
Soko <br>
