Automatic Transmission Fluid Details
The 2007 R320 utilizes the 722.9 transmission, which requires specific attention to the fluid color and datacard codes to ensure correct lubrication.
- Without code A89 (Reduced-Friction): The fluid is Red in color.
- With code A89 (Reduced-Friction): The fluid is Blue in color.
For both applications, the 7-speed 722.9 transmission has a total fill capacity of 9.5 quarts.
Diesel maintenance notes for this vehicle
Maintaining a Mercedes-Benz BlueTEC diesel engine requires attention to specialized components. Owners should be aware that BlueTEC technology involves advanced NOx reduction systems, which may include Selective Catalytic Reduction (SCR) using AdBlue or a NOx storage catalyst with a particulate filter. Regular monitoring of diesel exhaust fluid levels and particulate filter health is vital for long-term operation.
Common diesel oil-related concerns and how AMSOIL products may help
| Concern | Why it matters | AMSOIL product from this lookup | How it may help | Important limitation |
|---|---|---|---|---|
| Emissions System Health | Diesel engines use complex NOx reduction systems. | EOTQT-EA | Designed for exceptional protection without harming emissions systems. | Does not replace required exhaust fluid maintenance. |
| Cold Weather Starts | Thick oil can cause wear during startup in low temps. | EOTQT-EA | 0W-30 viscosity provides flow in various temperatures. | Must match specific temperature requirements. |
| Transmission Wear | High heat and heavy loads stress the 722.9 ATF. | ATLPK-EA | Withstands heavy towing and elevated temperatures. | Diagnosis required if mechanical failure occurs. |
Common maintenance concerns for this vehicle
Based on technical data, owners of the 2007 R320 should consider the following:

Recall, TSB, and manufacturer communication notes
NHTSA research indicates two significant recall campaigns for this model family regarding the hydraulic power assist vacuum in the service brakes:
Important: Owners are advised that these recalls can increase the risk of a crash. If your vehicle is affected, dealers will inspect and replace the brake booster free of charge. Always verify open recalls by using your specific VIN through an authorized Mercedes-Benz dealer or the NHTSA website.
About this vehicle
The 2007 Mercedes-Benz R320 is a luxury MPV (Multi-Purpose Vehicle) belonging to the R-Class family. This model year represents an era where Mercedes-Benz utilized advanced diesel technology, specifically the OM642 engine. The OM642 is a 3.0L V6 diesel engine characterized by its aluminum construction and common rail direct injection system.
The engine features a 72-degree V6 configuration with a counter-rotating balance shaft designed to mitigate vibrations, providing a smoother driving experience typical of the R-Class. This specific model is associated with Mercedes-Benz ‘BlueTEC’ technology, which focuses on advanced NOx reduction. Depending on the exact application, this may involve Selective Catalytic Reduction (SCR) using AdBlue urea injection or a combination of a NOx storage catalyst and a particulate filter.
The R-Class platform was shared with other Mercedes models like the M-Class and GL-Class, often utilizing long wheelbase configurations to maximize interior passenger space. Because BlueTEC implementations can vary between different vehicle applications, owners should verify their specific system requirements via official service documentation.
