今天的家庭作業是爆震感知器更換！318亮引擎檢查燈亮很久了，經插電腦檢查故障碼，為爆震感知器故障，其實這玩意不換大致並不影響行車安全，但因引擎狀況訊號無法回傳行車電腦，會變成超耗油轉速也不穩定，但這小東西要更換算是不小的工程，所以一般店家除非你堅持要換，不然他們是盡量不碰，就算要搞也要把車留在車廠至少1天，可見有多耗工！當然工資也不低啊！這週颱風天反正也閒閒，自己DIY更換吧！昨晚趁風還沒來時先要車材行幫我拿材料，再來就是到BMW官網下載要作業部份零件的爆炸圖，深呼吸一口（因為這工程一經開始就是一整天）就可以開始了，0800開工！M42型引擎要把整個引擎進氣系統，供油系統，發電機等部份全部拆除，才能看到這兩個小東西（早以破裂損壞），拆下後換上新品，順便把一些老化回壓管以新式矽膠管替換，所有管線或電系接頭記得要做好記錄才不會接錯，，順便把進氣极管積碳清潔，完成更換後將所有部件反向順序裝回！完成時間下午1630（中午沒休息），試車後故障燈熄滅了一切正常哦！引擎超順！酷哦！今天這工程扣除零件費用約省了7.8千塊工資哦，酷！！！
