| Description of the problem | I did some research on mercedes 3. 0l diesel motors and there seems to be an issue with the seal failing about 50,000 miles causing the motor to leak oil and the seal as well as the oil cooler need to be replaced. It is such a common problem on the 3. 0l diesel engines that when you call any repair shop the first thing they ask is if the car is a diesel. Also the seal replacement is all over the mercedes blogs saying the same issue on the 3. 0l diesels. Thought it might be something to look into as it is an engine seal problem and is occurring consistently in all the 3. 0l diesels in the s class, e class, ml class, g class. All models that mercedes sold the 3. 0l engine in the us. |
