Hi,

don´t forget the previous RDC in the E53, dissapeared apr 2004, I had one of the last paid as option. Useless stuff, always broken, many fake alarms, headache when changing tires, and so on...

Then they introduced RPA for free. It works and is enough. Obviously pressure per tire like others have is nice, but´s still a gadget since I am sure nobody will trust 100%.

Best regards
