BMW 328I Senzor tlaku v pneumatice

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 . 5 μA), musíte jej okamžitě poslat zpět výrobci, abyste zjistili, zda je deska PCB ohrožena zkratem a zabrání jej ovlivnit stabilitu signálu v následných modulech palivového systému, jako je obvod vstřikovače.

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%) nebo kyselá mytí aut (pH<4) for a long time.

If you have a BMW 328i Tire Pressure Sensor and an aftermarket turbocharger kit, you need to put a ceramic heat shield (P/N: 34-11-8-850-772) between the sensor and the high-temperature exhaust manifold. This will stop heat radiation over 150℃from speeding up the loss of lithium batteries. The X5 off-road variant has Složité požadavky na terén . Čtvrtletní údržba neutrálního čištění 3M ™ může udržovat přesnost vzduchotěsnosti přesné na 0 . 01BAR/rok v drsném podnebí a zvládnout všechny druhy podmínek silnic po celém světě, včetně solného spreje, extrémního chladu a vlhkosti.
