Hi.
The car it regards is Skoda Octavia combi 5E5 2013 model. The battery gets low after two to three days.
1. If i fully charge battery and it show 12.7volt and i turn the Key to on position the voltgae decreases to 12.3 or 12.4 volt.
If battery is charged to 12.4volt and i turn ignition key to ON, the voltage decreases to 12.0volt or 12.1volt.
2. I used voltmeter in my cars cigarette inlet and measured that it shows only battery voltage when idle to whatever it is at that poin 12.3volt as exmaple.
But when i turn on seat warming the voltage increase to 14.7 volt.
When i turn headlight switch to right to low beam it shows 13.2 volt.
3. Only sometimes it charge the battery on idle if needed i think and show 14.7 volt.
When i conencts vcds and measure battery current it show -10Amp taking from battery if engine in not started. Is there anything worng or is it normal?
Can anyone share their knowledge and experience?
4. I thought that alternator should not charge battery to as high voltage at 14.7 because it can damage the battery?
5. If there is a setting in VCDS that can bet set to tell alternator to charge battery all the time when battery is low, even if seat warming is on or not or when braking or not it would do the miracle.
Kind regards
