I use the basic knowledges that the lower screw is for draining and leveling and uper screw only for filling.
But not possible to find any documentation or book on this complete rdu and how to change these oil.
But yes, i changed these oil ( 75w85 and CH11S ) But im not sure about the quantity Who must be inside for the CHF11S and if must be some bleeding procedure with computer or other.
All these explainations to say that i have now this message when i try to get power from the car more than 3000 tr/min ( system AWD not available, anomaly. service required).
Thats why i want to know the procedure to replace the oil CHF11S, to see if i didnt forgot one step or did it wrong
Thanks for answers
