Mercedes Fault Codes List (Complete & Updated for 2025)
On this page, you will find a complete list of Mercedes fault codes.
A Mercedes fault code is a combination of letters and numbers that your car’s computer system uses to identify a specific problem.
You can read a Mercedes fault code by its structure. For example, if the code starts with a ‘P,’ it indicates a powertrain issue. Similarly, a code starting with ‘B’ indicates a body issue, ‘C’ indicates a chassis issue, and ‘U’ indicates a network issue.

How do you read Mercedes error codes?
Mercedes fault codes follow a specific format known as Diagnostic Trouble Codes (DTCs).
Each Mercedes error code typically starts with a letter followed by four digits, like P0301.
Here’s a quick guide to reading Mercedes fault codes:
- First letter:
- P = Powertrain
- B = Body
- C = Chassis
- U = Network
- First digit:
- 0 = a generic code
- 1 or 2 = a Mercedes-specific issue
- Second digit:
- 1 = Fuel and airflow monitoring
- 2 = Injection nozzles
- 3 = Ignition system and combustion misfiring
- 4 = Additional systems for emissions reduction
- 5 = Idle and vehicle speed
- 6 = Onboard computer and other outputs
- 7 = Transmission
- 8 = Transmission
- Third & fourth digit:
- Indicates faulty component and type of fault.
How do you reset Mercedes error codes?
Here’s a step-by-step guide on how to reset Mercedes fault codes:
- Use an OBD-II scanner: The most reliable way to reset error codes on a Mercedes is by using an OBD-II scanner. This tool can be plugged into the OBD port of your car, usually located under the dashboard, near the steering wheel.
- Connect the scanner: Turn off your vehicle, then connect the OBD-II scanner to the OBD port. Once connected, turn on the ignition to the “ON” position, but don’t start the engine.
- Navigate the scanner menu: Use the scanner’s menu to navigate to the ‘Diagnostic Trouble Codes’ section. Here, you’ll find the option to view and erase the codes.
- Erase the codes: Select the option to erase or clear the codes. This action will reset the car’s computer system and turn off the check engine light.
Conclusion
That’s it for our guide on Mercedes fault codes!
We’ve learned how these codes are your car’s way of asking for attention, how to read them, and even how to reset them.
So next time your Mercedes shares a fault code, you’ll be better equipped to understand what it’s saying.

where do you find them on a WD164 2010 300CDI
Hi Garry!
If your Mercedes has an OBDII port, you can use a Carly reader or a generic scanner from Amazon to find any fault codes.
Hope that helps!
