Resetting the check engine light on a 2017 BMW 5 Series Gran Turismo 535i xDrive can seem straightforward, but a light that’s simply reset without diagnosing the root cause risks masking a growing problem.

Choosing dealership service means transparent estimates, OEM parts, and factory-trained techs who understand the vehicle’s turbocharged inline-6 systems and emissions controls.

2017 BMW 5 Series Gran Turismo 535i xDrive Check Engine Light Codes

Common check engine light codes for the 2017 BMW 5 Series Gran Turismo 535i xDrive range from oxygen sensor faults (O2 sensor) to misfires, catalytic converter efficiency issues, or turbocharger and boost-related codes. In Decatur, GA, Nalley BMW of Decatur handles these codes with precise diagnostics and transparent estimates. For example, an O2 sensor code left unchecked can reduce fuel economy and damage the catalytic converter, turning a relatively inexpensive sensor replacement into a much costlier emissions component repair; dealing with it early saves both immediate expense and long-term replacement costs. Misfire-related codes may indicate ignition coil or spark plug wear — quick replacement prevents catalytic damage and maintains horsepower and torque. Turbocharger or boost control codes require experienced technicians to test related sensors and plumbing; addressing these promptly prevents expensive turbo or engine damage. Our dealership expertise, OEM parts, and warranty-backed repairs provide reassurance that independent shops may not match. We combine speed with accuracy—same-day diagnostics in many cases—and we offer service financing and targeted discounts through our service specials. Protect your investment by scheduling: schedule appointment today at Nalley BMW of Decatur for reliable, cost-effective diagnostics and repairs.

We emphasize immediate safety, long-term savings, and transparent service: fixing a flashing-light condition promptly avoids catalytic converter replacement and additional engine stress, which are far more expensive than timely repairs.
