Mercedes-Benz w202
Mb computer going crazy
It all started because something constantly draing 1,5A of battery while car is parked and locked. So i had to charge up battery every day or unplug it everytime i park. We checked what could drain it and found nothing. It wasnt radio and subwoofer so we checked fuse box and found one bad fuse and replaces it. After that when car was locked my dashboard light were flashing and air conditioning was on without key. And till this stops i doesnt even read key so i cant turn it. Then i managed to turn key and car started normally but after few minutes horn went crazy tho i didnt touch anything. I had to unplug battery to stop it since i kept going even without key. I tried again later and did the same after few seconds. I have w202 2.2cdi.
