2022 Mercedes-Benz E-Class Check Engine Light Reset

The check engine light reset process for a 2022 Mercedes-Benz E-Class requires more than erasing codes. Our technicians at Mercedes-Benz of Lynnfield first complete a full diagnostic to confirm the underlying fault, because clearing codes without fixing the issue can mask problems and lead to repeated failures. We use factory-grade diagnostic tools to detect pending issues, pending live data, and fault history. After repairs with OEM parts we perform a controlled test drive and verify repair efficacy; only then do we clear stored codes. This transparent approach preserves manufacturer warranties and ensures long-term reliability — and if your repair is covered under warranty it must be completed at a certified dealership.
