BMW 328iタイヤ圧力センサー

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）、PCBボードが短絡のリスクがあるかどうかを確認し、後続の燃料システムモジュールなどの燃料システムモジュールなどの信号の安定性に影響を与えないように、すぐにメーカーに送り返す必要があります。

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％）または酸性洗車液（ph<4) for a long time.

BMW 328iタイヤ圧力センサーとアフターマーケットターボチャージャーキットがある場合は、センサーと高温排気マニホールド.の間にセラミックヒートシールド（P/N：34-11-8-850-772}）を置く必要があります。複雑な地形の要件.四半期3M™中立クリーニングメンテナンスは、厳しい気候で0 . 01Bar/年に気密性を0 . 01BAR/年に維持し、塩スプレー、極寒、湿度など、世界中のあらゆる種類の道路状況を処理できます。
