Happy New Year! A couple of times recently, our 2000 e320 w210, with only 14,000 miles has refused to allow us to move the gear selector out of park. It appears to be an intermittent problem and the solution that we have found seems to be by pressing the switch that I believe would turn the alarm off for towing?? Whilst this solves the problem, it is not a long term fix and so any ideas? We have not had any problems with the brake lights which appears to cause this problem with others and it happens in both the cold and milder weather. I cant fathom why pressing that switch would solve the problem and what the underlying cause is. Thanks in advance.
