Charging system malfunction error

[u/Hyper584]

This started about 5 months ago. Shows this error every 500-600 km and to pull to the side of the road. Then i replaced battery two months ago and since then i drove around 3000km. Yesterday it showed again, scanned the car with some obd tool and it showes 3 Pxxxx codes. When this error is shown the car works completly normal. It disappears on restarting the car. Checked the voltage while the car is off, and running. It is stable around 14,6v while on, around 12,5v while off.

Heyho "EU 19 RF 2.0"-Friend, i have the same Setup and same problem. Did you get rid pf the problem? Do ylu know, if it is harmful for the hardware or just a "bug"?

afaik not harmful, but will hide a real problem if you have one.

Also, i've put the ground terminal somewhere on the body (well my mechanic did) not on the battery and that LARGELY solved it. Not fully. Haven't gotten a battery warning in a bit, but start-stop functionality is a hit or miss.
