Re: 04 E55 AMG: Restore TPMS system

Put the original module back in and "activated." This module operates a little differently than the used one I got. With the used one, when I select activate, it beeps and comes up with a message that the TPMS is activated. With the stock module, it doesn't beep or display anything except that I need to drive for a few minutes (or press R to reactivate again). After 15+ minutes of driving I got 4 pressures. However, when I shut it off and restart, it comes up and says that I need to reactivate again. Of course like the other module, I just clear that and the pressures are all there. I'll try a few days with the original module and see if anything changes but so far it seems that the behavior is about the same. Kinda odd. Would be nice to have no malfunctions (the holy grail).
