<p>Hi Michael,</p>
<p>Just to make sure: I'm talking about charging the main battery,
not the 12V battery. But I didn't check the status of the 12V
battery. But it would be weird to happen 2 times during a charging
process exactly after 20 mins.<br>
What I did is to log a complete main battery charge.
Results/Details see here:

<p>To your 2nd email:<br>
Yes, the values are for the DC converter of the main battery, not
the one for the 12V battery. All values are from this ECU:

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>
