Mercedes C220 CDI Problems

The Mercedes C220 CDI is a symbol of German luxury, blending performance and comfort. For individuals interested in buying a used C220 CDI, especially from the 2013 model year, understanding its common issues and associated solutions can be invaluable. Here’s a rundown of real-world experiences and advice on the C220 CDI BlueEf with the AMG Sport Plus pack, based on user reports.

Engine and Reliability

1. Injector Issues:
   • The early Blue Efficiency cars had injector problems, which were traced back to a design change by Delphi. However, Mercedes addressed this problem by replacing the problematic injectors free of charge, costing them millions.
   • These cars then received updated Bosch injectors which are reported to perform reliably.
2. Mileage and Longevity:
   • The C220 CDI engine has been noted to be reliable, with reports of vehicles covering over 200,000 miles without significant engine issues.
   • The engine employs a chain drive, which is typically durable and less prone to issues.

Automatic Gearbox

1. 7G Transmission:
   • Some vehicles equipped with the 7G gearbox might exhibit rough downshifts. A software update is believed to address this concern.
   • It’s essential to check the vehicle’s fluid change history. While some vehicles might be listed as having a “sealed for life” transmission fluid, it’s recommended to change the fluid and ensure the torque converter is flushed properly. For a car with around 14,000 miles, however, a fluid change might not be immediately necessary.

Interior and Build Quality

1. Interior Materials:
   • Buyers should inspect the car’s interior materials, especially the seats. Some trim levels might come with ‘Artico’, which is described as a ‘man-made leather’. This isn’t true leather and might not offer the luxurious feel one would expect from a Mercedes.
   • Some owners have also reported occasional interior rattles, a minor inconvenience that should be checked during a test drive.

Other Potential Concerns

1. Water Pump Issues:
   • The water pump, particularly on the E class variant, is known to be a potential weak point. While it’s made of plastic, it’s also known to be relatively inexpensive to replace. However, if left unchecked, a malfunctioning water pump can lead to more severe issues.
   • Early symptoms include a change in the sound of the pump and the “check coolant level” warning. If these signs appear, the vehicle should be inspected immediately to avoid further complications.

Concluding Thoughts

In essence, the Mercedes C220 CDI is a reliable luxury car with a few known issues. For potential buyers, especially those transitioning from other luxury brands, it’s essential to be informed and thorough when inspecting a used C220 CDI. With proper maintenance and timely interventions, it promises to be a car that blends performance with luxury, making for an enriching driving experience.
