The service DVDs from Mercedes contain the same WIS procedures used by dealerships.
They are NOT designed for amatuers, and the thought there is a "for dummies" book out there somewhere is ludicrous.
Professional mechanics are just that, professional, and to think someone with zip for experience can do their same job just by referencing a book is dreaming and it's an insult to folks who make this their profession.
One really should doubt that something inexpensive on eBay is anything but information pirated from reputable sources. Who do you suppose has the resources to first obtain the car and then spend hours and days and months taking one apart, etc., to produce a manual on their own? There aren't enough Mercedes in the world to justify the expense, as the lack of Haynes manuals ought to demonstrate.
The best bet is
get the factory WIS procedures
own plenty of really good tools and learn how to use them
have a degree in mechanical engineering or otherwise lots and lots of automotive experience
Without these things, Mercedes DIY is fantasy.
