The problem of excessive noise in the 4MATIC system of the Mercedes C300 is a common complaint among owners of this model. This noise can come from various components of the system, such as the transmission or transfer case. Causes of this can be worn gears, low fluid levels, contaminated fluids, or defective seals that allow air to escape.
This problem can be identified and remedied by a thorough diagnosis from an experienced Mercedes-Benz mechanic or an authorised Mercedes-Benz workshop. It is important to provide all relevant information about the problem to enable a quick and accurate diagnosis. During the inspection, the transmission and transfer case fluids should be checked and replaced if necessary.
Oil leaks in the 4MATIC system of the Mercedes C300 are another common weakness. These leaks can be caused by defective seals, worn parts or faulty assembly. The inspection should focus on the transfer case and transmission, as this is where most leaks occur.
Once a leak is noticed, it is advisable to take the car to a workshop as soon as possible to identify the source of the leak and carry out any necessary repairs or part replacements. An unrepaired leak can lead to further mechanical damage and shorten the lifespan of the system.

Excessive vibrations while driving are an indicator that something in the 4MATIC system is not working correctly. These vibrations can be caused by worn flex discs on the drive shaft, which can be damaged by intensive use over time. If these discs become cracked, this can cause significant oscillation and vibration while driving.
To solve this issue, it is best to consult a professional Mercedes-Benz mechanic to inspect and replace the worn discs. Ignoring this problem can have a negative impact on the drive shaft centre bearings, differential, and transmission assembly.
The 4MATIC system on the Mercedes C300 depends on several electronic modules and sensors to function correctly. If these components become defective, the system may react unpredictably or even fail completely. Common causes of sensor and module problems include cable damage, damaged parts, corroded components or dirty parts.
This problem can be solved by a certified technician replacing defective parts with new, original components from an official Mercedes-Benz dealer. However, if the problem is only caused by minor corrosion or dirt, a thorough cleaning of the affected components may be sufficient.
The Mercedes C300's ABS system can fail prematurely, especially on pre-2012 models. This failure is often caused by a dirty brake fluid system. A regular fluid change every two years can help prevent this problem.
The Mercedes C300's braking system is usually excellent, but there are reports that the brakes begin to squeal over their lifespan. This occurs because the brake discs are deformed by the size and material of the brake pads. Therefore, the brake discs often need to be replaced at the same time as the brake pads, especially on models before 2012.
Oil leaks at the cylinder heads of the Mercedes C300 are another problem that occurs particularly in models between 2008 and 2012. These leaks are often misdiagnosed as leaks in the valve covers, but the real problem lies in the plastic expansion plugs. These plugs need to be replaced every 60,000 miles to prevent the problem.
Vibrations transmitted through the centre console of the vehicle can be caused by cracks in the flex discs of the drive shaft. This problem must be fixed immediately to avoid damage to the transmission assembly, especially on pre-2012 models.
