機油刻度問題
第2章節內容提到更換重點就是油尺-> Remplacement de la jauge à huile.
以207 HDi 1.6為例,原油尺量測頭是黃色因為刻度不準造成所加的機油量其實是不足的, 潤滑不足最後會造成如圖中的渦輪軸螺帽脫落或損毀.
除了更換渦輪之外還要更換橘色量測頭的新版油尺(油底殼漏油或里程6萬KM以上則連油底殼要一起換). Turbo charger軸心壞了為什麼法國原廠要換新版油尺?? 章節2-4 intervention內文有提到新版油尺才是準的. 繼續按著不準的刻度加機油繼續用, 想當然只會讓新Turbo charger繼續壞.. 若Turbo charger軸承螺帽掉了或損毀, 進/回油管及油封都要更新, 且整個進氣系統都要檢查是否有異物或油漬. 以新油尺為準, 機油要加到如圖中油尺標記10 跟11中間, 建議加到標記10, 但不要超過.(發動待速五分鐘之後熄火, 休息15分鐘之後量)
RPO 12123之前出廠的207 HDi 1.6新油尺為RP 1174 E6, Jauge à huile ( Référence P.R 1174 E6) . 以後新車引擎系統會直接改用1174 G2.(針對RPO 12124以後出廠車輛)

黃色橘色油尺比較圖1黃色略長一點, 所以末端會深一點.
黃色橘色油尺比較圖2 橘色刻度比較高, 按照建議加到標記10,橘色的油會更多. 討論是說油會高出14mm以上, 之前用黃色的如果沒加滿會差更多.

HDI 1.6出現以下其一徵狀要特別注意此油量問題: (新版文件有另外提到)
a. 無力. 註解:渦輪進油的吸油孔(引擎前方)的確比油底殼高很多, 油量不足潤滑不夠的確有可能沒力.
(吸油孔在引擎前方較高位置. 若油量不足, 渦輪進油管在爬陡坡時不知道會不會比較吸不到??)
b. 引擎警告燈.
c. 渦輪噪音.
d. 排氣管排放煙霧.

德國-1 Turbo維修文件開宗明義主旨中就點出PSA HDi1.6的通病, 機油供給不足
Damage to turbo-PSA engines
1.6 HDi (9HX) and 1.6 HDi (9HY/9HZ)
第二頁也提到一定要換成1174 E6機油尺.

德國-2, 好像修Turbo的都知道PSA HDi 1.6這個問題,
另外一家, 一樣知道是機油供給不足

英國 ayers_spares: PSA 1.6HDi機油量不足會造成機油中累積高濃度的碳, 最先壞的就是230,000RPM的渦輪.
The PSA 1.6HDi, DV6TED4 engine is a highly sophisticated low emission, high power diesel unit. It is used in many different applications; Citroen, Ford, Mazda, Mini, Peugeot and Volvo.

Due to the engine being clean and powerful, it is designed to operate at high temperatures, which demands the very best lubricants. These lubricants must be maintained in peak condition and PSA have fitted an in-line oil filter to the turbo and an integral oil cooler/oil filter to this engine to ensure this. However there is a drawback to this; reports in the field indicate that if the engine has been operated with the oil level below normal limits, this may potentially cause a high concentration of carbon in the oil. This may then lead to blockage of the in-line filter, oil cooler and main oil filter, which will eventually bring on premature turbo failure. The vacuum pump may also suffer from this same type of contamination.
However, due to its high operating speeds (230,000 revs per minute) the turbo will usually be the first to show signs of damage. This can happen from 30,000 miles onwards if the oil level and correct oil change intervals/procedure have not been adhered to.
