Hello, my 2012 C250 is having some problems. The car drove just fine prior to parking into the garage. It was raining before I got it in the garage. The next day I went out to leave for work and the fog lights started flashing, interior lights flashing, the park light indicator is flashing, antitheft is on. I can pull the N relay and all the light will stop flashing. The flashing is random, not in any sync to anything at all. I cannot start the car. I disconnect the battery and waited half hour or more then hooked it back up and nothing has changed. When I hit the lock button the light wont flash and there is no beep beep sound. Under settings it shows these options are enabled. I think it's some electrical problem after the N relay. I also heard that it could be the alarm/siren could cause all these exact problems I'm facing due to the backup batteries leaking and shorting the board out. But I cannot find the alarm anywhere. I see some MB have it in the passenger wheel well or the driver side wheel well. I have checked and it is not in either of these locations. If I could find that and take it apart then I'd know if it is that. Anyone know where its located on a 2012 c250? Anyone else have these problems? What did u do to fix it. I have a warranty I'm just stubborn if it's an easy fix.
