Would somebody know to explain what exactly Service A, B, C, D
…etc indexes mean?
Reason for asking is that as of now I am doing regular servicing on my A150. Oil and filter changes, etc.
I would appreciate if someone could elaborate what each index (A, B, C…etc) means in sense of service (what should be changed etc.)
Just in case admin tells me to do a search on this subject before asking a question, I have searched and couldn’t find an answer
PS. should someone know where I could get a workshop or maintenance manual for this vehicle pls let me know.
