Mercedes ignition problem HELP

Asked by Jan 15, 2017 at 10:31 PM about the 2001 Mercedes-Benz CLK-Class CLK 430 Coupe

Question type: Maintenance & Repair

I have a very weird case. I turn off my key and
when I pull it out the ignition doesnt lock, in order
for the ignition to lock I have to pull the switch for  
my lights (activating my brights) then I here the
ignition lock. Then I'll get out lock my car and
within 3 to sometimes up to 30 min the dash will
light up and radio will one on as if some one
inserted a key and turned it to positionn 1. This is a  
HUGE PROBLEM because not only does it drain the
battery but I have a breathalyser interlock system
and this machine then also thinks I someone put a
key in and that's a violation for the machine if no
blew. Which then activates the breathalyser bulk in
alarm the wakes everyone up or goes off in parking
lots . PLEASE HELP !

Maybe the ignition lock is worn out.

if this problem arose post breathalyser, I would suspect it, as the symptoms you describe are bizarre for an untouched ignition system. Usually, it fails and needs to be replaced, not deciding when to work on its own. There is a failure somewhere, but I don't think its in the ignition system as originally installed.
