Certain Mercedes services involve replacements, which can be pricier compared to inspection-only requirements. You already know that right?

In such cases, many Mercedes owners with some mechanical know-how opt for a do-it-yourself approach to save on costs. 

When you choose professional mechanics or dealerships, the charges typically include the price of replacement parts, labor costs, and inspection fees. 

However, with a DIY approach, you’ll only incur the cost of the replacement parts. 

To give you a rough estimate, a Mercedes A9 service from a dealership might range between $550 and $750.

My advice is to obtain quotes from multiple nearby dealerships and select the one that offers the best service. And, if you possess some mechanical knowledge, go for the DIY.
