Good afternoon everyone. I have a problem for a while now with my audi a4 b8 avant and is starting to be really annoying. It started with radio not working for more than 2 min without engine running and now I have no "coming home" lights, message that battery will charge while driving, music starts every time with the first song on the playlist...... I have changed the battery twice. One bought it from ebay in march and last week bought another one from Halfords. I had a while back mounted a subwoofer straight from the battery but for a short time and a led strip with flowing lights but I just removed it and still nothing. Nothing else connected. I bought a Carly Vag OBD with the pro app and test it and is the same fault every time :
"CAN Gateway
Fault Code: P0BE1
Fault Explanation: Energy Management Active
CAN Gateway
Fault Code: P0BE1
Frequency: 1
Unlearning Counter: 115
Mileage at last occurence: 102252.805 mi
Details about fault status: A test failed since last fault clearing

Forgot to mention that I've been to kwik-fit in 2 location and one halfords and checked the battery and alternator and is all ok
Please advise me what should I do.
Thanks
