2011 Mercedes-Benz SLK-Class SLK300 Check Engine Light Codes

The most common check engine light codes for the 2011 Mercedes-Benz SLK-Class SLK300 include oxygen sensor faults (P0130–P0167), catalytic converter efficiency issues (P0420), misfire codes (P0300–P0312), and evaporative emission system codes (P0440–P0455). In Dallas, Park Place Motorcars Dallas diagnoses these codes using Mercedes-Benz factory software that reads stored freeze-frame data and live parameters to pinpoint whether a sensor, wiring, or component replacement is needed. Ignoring these codes can lead to reduced fuel economy, higher emissions, engine damage, and expensive catalytic converter replacement—costs that escalate quickly compared with early intervention. Our certified technicians provide clear estimates and often save customers money over independent shops by avoiding unnecessary parts replacement and ensuring repairs are done right the first time. We also honor warranties when covered work is performed at our certified service center.
