Check Engine Light Flashing

A flashing check engine light in your 2018 BMW i3 indicates an active fault that may affect drivability or battery systems and requires immediate attention. In many electric vehicles a flashing lamp can point to intermittent battery management alerts, high-voltage issues, or software anomalies that – if ignored – may lead to reduced range, unexpected limp-mode events, or accelerated wear on components. At Nalley BMW of Decatur our technicians begin with a BMW-specific scan, review live data, and perform targeted electrical and software checks to find the root cause. Our diagnostics reduce the risk of unnecessary part swaps and return visits, delivering both immediate savings and long-term cost avoidance. If a repair is required, we use OEM replacement components and authentic programming to preserve factory warranties; remember that warranty-covered repairs must be done at a certified dealer to remain valid. We regularly publish service specials to lower your out-of-pocket cost, and service financing is available so you can get the necessary work completed today. Don’t wait: a flashing light is a higher priority — schedule service online now to protect performance and safety.

2018 BMW i3 Check Engine Light Reset

Resetting the check engine light on a 2018 BMW i3 is straightforward when the underlying cause has been diagnosed and repaired, but clearing codes without resolving the root issue can mask problems and lead to bigger expenses later.

Choosing our service team delivers transparency — we provide written estimates, explain repair options, and use OEM parts and BMW programming standards so your vehicle maintains optimal performance and warranty compliance.

2018 BMW i3 Check Engine Light Codes
