How To Check Engine Oil Mercedes-benz

How to Check Engine Oil in Mercedes-Benz Vehicles

Mercedes-Benz vehicles represent German engineering excellence and luxury. Like BMW, many modern Mercedes-Benz models (2007+) no longer have a traditional dipstick. Instead, they use an electronic oil level monitoring system via the dashboard display. However, some models, especially AMG variants, may retain a dipstick.

⭐ Mercedes-Benz Key Feature

Most Mercedes from 2007+ have NO DIPSTICK. Use ASSYST PLUS system via dashboard to check oil level electronically.

Two Methods for Mercedes-Benz

Method 1: Electronic Check (2007+)

For modern Mercedes without dipstick

C-Class, E-Class, S-Class, GLC, GLE, GLS (newer models)

Method 2: Traditional Dipstick

For older Mercedes (pre-2007) or some AMG

Older models, some AMG variants

Method 1: Electronic Oil Check (No Dipstick)

Step 1: Prepare the Vehicle

Park on level ground. The engine must be at operating temperature (drive for at least 10 minutes). Turn off the engine and wait 5 minutes before checking. The car must be completely level and stationary.

Critical: Mercedes electronic system requires warm engine and level ground. Will not work properly if cold or on slope.

Step 2: Access ASSYST PLUS System

For MBUX (2018+)

Turn on ignition (don't start engine)
Press "Vehicle" on center screen
Select "Service" or "ASSYST"
Choose "Engine Oil Level"
System measures for 30-60 seconds

For Older Display (2007-2017)

Turn key to position 2 (ignition on)
Press steering wheel button repeatedly
Navigate to "Service" menu
Select "Engine Oil Level"
Wait for measurement
