I have a brabus lowering module on my E55, only recently fitted by MB, I dont know if this of help, (I am totally non mechanical), but I did read the fitting and initial start up procedure, (still have the instructions somewhere), it stated that once the module is fitted, the batteries reinstated, that the car should be raised at first to the highest suspension setting, then to the lowest setting, and this action would trigger the brabus module. I am wondering to weather with the batteries having been disconnected, that this procedure has not been carried out and needs to be. A long shot, especially as I don,t know a thing about these items. As for speaking to Brabus, absolute nightmare! nothing happens very quickly, need to be patient, I eventually got my answers to my queries over the course of 2 weeks, via numerous E mails.
