I'm not familiar with the newer models, though the older models had the box mounted under the rear seat. The adjustments were there. The instructions should be in your Owner's Manual.

I had found a 2004 E class User's Manual Online. (Page 89) Mentions nothing about sensitivity adjustments. Only addresses arming, dis-arming, and towing selections. From that I can only assume that it may be a faulty switch. Either door, trunk/hatch lid or hood/bonnet. Or it could be something as simple as a poor ground or hot lead in the wiring of those switches.
