BMW 328i Sensor de pressió dels pneumàtics

Since this is a manufacturing solution created just for the BMW Tyre Pressure Sensor, the torque accuracy needs to be adjusted after installation to meet the system. Use a VDA-certified electronic torque wrench (1.2–1.5N·m range) to tighten in three steps: first, pre-tighten with 0.5N·m to close the gap; then, tighten with 1.2N·m to make sure it seals; and finally, turn the wrench 15° in the opposite direction to relieve the metal stress. If you have changed wheel hubs, you must follow the BMW-approved process for replacing the tire pressure sensor. This means using the ISTA/D diagnostic system to do "TPMS Reset + CAN Bus Binding" and measuring the valve hole tolerance three times with a Mitutoyo micrometer. If the sensor sleep current is too high (>3 . 5μA), heu d’enviar-lo immediatament al fabricant per esbrinar si la placa de PCB està en risc de curtcircuit i evitar que afecti l’estabilitat del senyal en mòduls del sistema de combustible posteriors, com el circuit de l’injector.

The fluororubber seal on the BMW Tire Pressure Sensor can handle temperatures as low as -40°C and as high as 125°C when the brakes are hot. However, the sensor base needs to be cleaned with 3M™ Citrus Cleaner neutral solvent every three months if it is exposed to calcium chloride de-icing agent (concentration >5%) o líquid de rentat de cotxes àcids (pH<4) for a long time.

Si teniu un sensor de pressió de pneumàtics BMW 328i i un kit de turbocompressor de postvenda, heu de posar un blindatge de calor ceràmic (p/n: {{1}) entre el sensor i el col·lector d’escapament d’alta temperatura Requisits complicats del terreny . Manteniment de neteja neutra trimestral 3M ™ pot mantenir la hidromassitat precisa fins a 0 . 01Bar/any en climes durs i manejar tot tipus de condicions de la carretera a tot el món, inclòs ruixat de sal, fred extrem i humitat.
