Check Engine Light Flashing

A flashing check engine light on your 2016 Mercedes-Benz S-Class often indicates a misfire or another condition that can cause immediate engine or catalytic converter damage.

At Mercedes-Benz of Lynnfield in Lynnfield, MA, our technicians perform a thorough diagnostic that goes beyond reading codes: we perform targeted tests, road checks, and OEM-level inspections to isolate the root cause and prevent collateral damage. Acting quickly saves you money by avoiding expensive downstream repairs like catalytic converter replacement and preserves engine performance.

Using dealer-grade equipment ensures codes are cleared properly and that pending adaptations are handled per factory specifications. Our transparent approach highlights warranties, genuine OEM parts, and certified technician expertise — and we stress that warranty-covered repairs must be completed at a certified dealership to maintain coverage.
