The "W204" in Mercedes refers to a chassis code that describes the fourth-generation (W204) of the Mercedes-Benz C-Class. Each series of Mercedes vehicles is assigned a unique code to differentiate it from other models. The W204 specifically denotes the C-Class models built between 2007 and 2014.

The top speed of the Mercedes-Benz W204 will vary depending on the specific model and engine configuration. However, most variants of the W204 have an electronically limited top speed of around 155 mph (250 km/h).

Some common problems with the Mercedes C-Class (W204, 2007 model) include:
1. Electrical issues: This generation of C-Class can sometimes experience electrical problems, such as faulty modules, wiring issues, and malfunctions with the multimedia interface.
2. Timing chain tensioner: The timing chain tensioner in the M272 and M273 engines (3.5L V6 and 5.5L V8) can wear out and lead to timing chain failure. This issue can cause severe engine damage if not addressed promptly.
3. Balance shaft gear failure: In the early W204 models, the balance shaft gear made of plastic can fail, resulting in engine performance issues. Mercedes-Benz issued a recall for this problem, and affected vehicles should have had the gear replaced.
4. Transmission problems: Some owners have reported transmission slipping, rough shifting, or even complete failure in the C-Class. These issues can be caused by a faulty conductor plate, valve body problems, or issues with the torque converter.
5. Suspension issues: The front suspension components, particularly the control arm bushings and ball joints, can wear out over time and cause clunking noises or unstable handling.
6. Cooling system problems: Coolant leaks, particularly from the radiator, water pump, or hoses, have been reported in some C-Class models. These leaks can lead to overheating and potential engine damage if not addressed.
7. Oil leaks: Some owners have experienced oil leaks from the engine, particularly from the valve cover gaskets and oil filter housing gaskets. These leaks can cause oil consumption, foul smells, and potential engine damage if oil levels are not monitored.
It is important to note that not all C-Class vehicles will experience these problems, and regular maintenance and prompt repairs can help minimize the risk of issues. It is recommended to have a pre-purchase inspection performed by a qualified mechanic if you are considering buying a used Mercedes C-Class.
