Battery drain

[tier26]

Hi, i have 2008 octavia and about a week ago i started to have problems with battery drain. I measured with multimeter and the result is 1.1A when the car is shut down. Radio takes about 0.52, starter 0.17, data bus 0.17 and automatic gearbox control unit 0.08. I dont know about the other things but the radio is definitely not normal, i have upgraded original stereo to android unit but i didnt have to change any of the factory connections and i upgraded about a year ago but the problem started last week so... Some advise would come handy... Excuse my poor english

I don't know what Radio you have but does it have a CD in it or a multi CD player in the boot? Both of those can cause trouble apparently.

Yes, it did have a cd in, but it has been there for months. Ill measure it tomorrow and see if that made any difference, thanks for the advice..

The radio might have always been drawing power but you might not have noticed it until now. A slightly more tired battery and colder weather could have shown up the problem.

 

I'd try unplugging the radio and see if you still have the problem (or pull the fuse etc).
