Personaly this forum has saved me many thousands. But you get what you pay for and this forum is free... I don't think anyone should try to work on there Mercedes without a FSM. With said FSM you can then see the proper procedures, and use the forum to clear up things that may not understand.

If you do not feel comfortable working on a Mercedes bring it to a shop.
