A Fixo Das Auto

Hi guys, few words what I'm doing. I'm trying to make short videos that people could make a repair on they own cars instead of going to dealer and get drained for $$$. I'm trying to make it as much as simple and understandable for majority.   
I don't have much videos but I'd like to know what I'm doing wrong or how should I do it. Comments, questions or suggestions are welcome.  I speak few languages : English, German, Russian and Lithuanian. So don't hesitate to ask, and for the question why I do all this in English, answer is simple: it's wide spread language and lot of you know it at list basics.
