Do i need to replace my battery if the below arent functioning as they should be? or dose something need to be fixed?

I was at the dealer to get my brakes done, and some warranty work....

My automatic wipers dont go off when they are on unless i set them off then it will be automatic...

My front windshield defogger dosent blow any air for atleast 5minutes after starting the car...

My auto interior lights arent automatic unless i manually turn it on....

Sometimes when i turn my car on, the cd player starts clicking and wont turn on and it will say amplifier not available...i would have to restart the car for it too work...

anyways those were what i was going in to see if those would be cover under warranty....

The dealer told me that i would just be wasting time for them to try and diagnost it, the problem is i need to replace the battery under my seat....

Replacing the battery would fix all my electronic issues

I have never heard anything like this before....

What you guys think?

thanks

 

no chance, your describing 04 known issues with new batteries

 

if you have warranty yes take it back..

I dont know if porsche has the option or not, ( ive only had one a 3 weeks) On my old G500 you could scroll threw the setting in the command unit and see what your batter and voltage was doing in real time.

Ive seen cars have probs with a batt but not like that... like i said thought im new to porsche.

 

I Have never heard of electronic components not working because the battery needs replacement. It sounds like it might be something else
