2019 BMW 6 Series Gran Turismo Check Engine Light Codes

The most frequent check engine light codes for a 2019 BMW 6 Series Gran Turismo in the Decatur area include oxygen sensor (P013x–P016x), catalytic efficiency (P0420), misfire codes (P0300–P0306), and evaporative system faults (P0440–P0457).

We emphasize convenience — same-day diagnostics where possible, transparent pricing, and OEM parts that preserve performance. Addressing codes promptly saves money today and protects long-term resale value.

Nalley BMW of Decatur advises pulling over when safe and arranging transport to our service center rather than continuing to drive.
