BMW 328i senzor pritiska u gumama

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), morate ga poslati natrag proizvođaču odmah da biste saznali da li ploča PCB-a u opasnosti od kratkog spoja i zadržati ga da utječe na stabilnost signala u kasnijim modulima za gorivo, takav krug ubrizgavanja.

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%) ili kiselo tečnost za pranje automobila (pH<4) for a long time.

Ako imate senzor pritiska BMW 328i i komplet turbopunjača u traku, morate staviti keramički toplotni štit (p / n: 34-11-8-850-772) između senzora i visokotemperaturnog ispušnog razvodnika. To će zaustaviti toplinsko zračenje preko 15 0 stepen da ubrza gubitak litijumskih baterija. Varijanta X5 van puta ima komplicirane potrebe za terene. Tromjesečno održavanje od 3M ™ za čišćenje može zadržati precizno precizno na 0.01bar / godišnje u oštrim klimama i rukovati svim vrstama cesta u cijelom svijetu, uključujući sprej soli, ekstremne hladnoće i vlage.
