I've been having middle-heavy problems with my 8s since Tuesday.
On Tuesday in the evening I noticed for the first time that the lights for "ABS" and "CAT" flickered when standing in idle...
On Wednesday and Thursday my brother had the car and when he went to work on Thursday, the V8 died at a crossroads and did not jump on (after the same lights flickered and, on top of that, the battery lamp and the battery symbol lit up in the car check...)

He then charged the battery and then he drove him home in the evening.
When I wanted to go back to work today, the lights for "battery" and "CAT" flickered (in the beginning only in idle mode, then even while driving). Also the symbol was displayed again after some time, nagut V8 turned off and continued with Bim...

Does anyone have any tips and suggestions for troubleshooting? Has anyone ever had similar problems?
Is the alternator in the A****? Or the battery (where it could be charged?!)?
Greetings to Mark
