I haven’t will give it a try. I don’t want to disconnect the battery every time I turn the engine off.

Have already been to auto electrical who spent 2 hours checking the. Electrical systems couldn’t find a fault

I have 2007 Audi A6 2 litre estate. I have a nearly new high powered battery. I can fully charge the battery and less than 24 hours later the battery is to low to start the car. I have had the. Car checked by an auto electrician. the alternator is delivering 13.6volts the jump poles in the engine bay are showing. 13.4volts when I turn off all equipment but leave the engine running no leakage detected. no idea what to do next any ideas please. don’t want to take it to main dealer with open ended problem . Too expensive. car starts straight away when use a external battery booster.
