2010 Mercedes-Benz R-Class Check Engine Light Codes

Common check engine codes for a 2010 Mercedes-Benz R-Class include sensor-related codes (oxygen sensor, MAF), EGR/DPF system codes for diesel emission control, and occasionally battery/charging system codes that affect engine electronics. Left unaddressed, oxygen or MAF sensor faults reduce fuel efficiency and can lead to higher emissions and turbocharger strain; unresolved DPF or EGR codes can cause costly repairs or component replacement. Battery and charging faults can trigger erratic engine behavior and electronic malfunctions. At Park Place Motorcars Dallas in Dallas, TX, our certified technicians diagnose these codes quickly, present clear repair options, and explain cost-to-benefit outcomes so you can make an informed choice. We emphasize the immediate savings of accurate diagnosis and the long-term savings of OEM repairs and warranty-backed parts.
