Imi voi raspunde singur, in ideea ca poate va interesa si pe altcineva pe viitor : Incepand cu modelele F10 LCI, masinile au acesti direct RDK sensors care sunt explicati mai jos (text de pe Atu.de) RDKS = Reifendruckkontrollsystem oder TPMS = Tyre Pressure Monitoring System advantages More safety for all road users through optimum tire pressure (braking distances, blowouts, cornering stability, ...) No higher fuel consumption due to wrong tire pressure Reduce tire wear due to perfect tire pressure Minimization of CO² emission of each vehicle, reducing the greenhouse effect Loss of tire pressure is immediately displayed and a deficiency can be remedied in good time Air pressure must not be so frequently checked Disadvantages with a new set of wheels the sensors need to be re-learned on some vehicles in specialized stores slightly higher cost of the sensors, but pay for themselves through the described benefits Valve needs to be serviced with new tires Legal requirements for the equipment of vehicles with a Tyre Pressure Monitoring Systems Since 1 November 2012 all the EU newly homologated cars, SUVs and RVs must be equipped with TPMS. From 1 November 2014, all registrations of passenger cars, SUVs and RVs must have a TPMS in the EU. IMPORTANT: Retrofitting older vehicle registration is not necessary! In the general inspection of vehicles with a standard Tyre Pressure Monitoring Systems, a non-functioning TPMS as low deficiency §29 StVZO listed in the test report. This deficiency must be remedied immediately. What's installed in my car and as I find it out? a direct system displays on the screen exactly the air pressure (see vehicle manual) an indirect system is a warning lamp in the car (see owner's manual) a vehicle without TPMS has no ads in the vehicle cockpit What is the difference between direct (active) and indirect (passive) TPMS? direct (active) RDKS the air pressure is displayed accurately in bar on the display, measurement tire pressure sensors it must sensors at each wheel to be present manual control of the air pressure is omitted DANGER: In a direct TPMS new sensors must be trained on the car, that is, during the assembly of a new wheelset following Anlernprozesse may occur, the / depend on the vehicle brand model: selbstanlernende sensors Teach about the vehicle menu Teaching the sensors via the on-board diagnostics system
