I'm not quite sure if this is the best Stack for my question but I will try. So from some time I noticed that in my car when engine is turned off there is still quite huge power consumption which causes after 3-4 days I cannot start the engine. After some measurements I noticed that radio consumes too much power after I turn off engine. What is more this radio (blaupunkt) is damaged and it doesn't insert the cd and by this problem the message "Note: CD error" pops out on the screen from time to time.
And now my question: is it possible that this "cd error" problem can cause some variations in my radio while engine is turned off?
I'm asking because I would like to know if there is something I can do before I decide to give it to some specialists.
Thank you for any help.
EDIT: So today I did measure it again. Firstly it showed again 0.8A then we decided to turn off radio with its button. When we hit the button the value 0.16A was shown. So we were thinking what is still consuming power. After that we decided that we will wait half an hour and then probably it will go into sleep mode. What is funny, when we came back after half hour the value 0.64A was shown! Simple math and we got 0.8 - 0.16 = 0.64! Somehow when the car went into sleep mode the radio started to consume power. Now I am sure that only radio is someway broken so during the week I will go visit some specialist so they can repair the radio.
Thank you for all your help.
