Hi guys, i have a w203 2002 C180 and i currently have a battery drain problem, it killed my battery last friday, tried testing some modules i thought were culprits but to no avail, any suggestions?
 
Try disconnecting the alarm module - behind the wheelarch liner on the passenger side iirc.
That’s a common culprit.
 
Hello and welcome .As Ted say's ^^^ . Do this first , it's cheap and easy to do.

If that does not work do this.

How old is you battery?.....and how often is the car driven a reasonable distance?
