Types of Service & Repairs For Your Mercedes

Mercedes-Benz CL63 engine repair at our Mokena location
Your personal driving style and type of daily use can affect the service and repair requirements of your Mercedes-Benz. This is condition based servicing. At every visit, we’ll inspect your car to establish condition, safety and wear. The inspection results and diagnostic recommendations specific to your Mercedes help you to effectively plan for future maintenance costs.
Save Money on Services for Your Mercedes-Benz
Your Mercedes-Benz uses Assyst Plus to indicate recommended vehicle maintenance intervals. The lettering for the recommended maintenance ranges from Service A through Service G and will be indicated on your instrument cluster. The service intervals are calculated on the basis of time, and mileage driven. Some service items, such as brake fluid, age through time as well as mileage, so an annual service regardless of mileage can become important to address these. Mercedes-Benz has specific technology that requires precisely timed service such as transmissions, 4-matic drive systems, superchargers, diesel particulate filters and air ride suspension.
Staying on top of service for your vehicle is important, but it can often get pushed to the back of our minds with all the busy things we have to do on a daily basis. At each visit, we’ll inspect your Mercedes and make you a list of priorities. You’ll receive timely email reminders of when your next service is due
Below is a list of services and repairs we provide to our Mercedes-Benz customers. If you do not see the service you require or have questions regarding a diagnosis of a vehicle problem, reach out to us at (708) 687-5258 or use the enquiry form below.
