Check Engine Light Flashing

The moment a check engine light flashes on a 2016 Mercedes-Benz S-Class it signals an active misfire or another condition that may cause immediate engine damage or catalytic converter harm. A flashing warning often means the engine is running outside safe parameters and continued driving could cause expensive downstream failures. At Park Place Motorcars Dallas our team prioritizes these vehicles for immediate inspection: we perform a complete diagnostic scan, targeted road tests, and component checks using OEM tools to isolate ignition, fuel, or sensor faults. Addressing a flashing light promptly reduces repair cost and prevents collateral damage to turbochargers or emission systems — delivering both immediate savings and longer-term value. We offer transparent pricing, manufacturer-grade replacement parts, and service financing so customers can get critical repairs now and pay over time.

2016 Mercedes-Benz S-Class Check Engine Light Reset
