2020 BMW X4 Check Engine Light Codes

The most common trouble codes on a 2020 BMW X4 typically point to oxygen sensors (P0130–P0167 range), misfires (P0300 series), or evaporative emissions/purge faults (P0440–P0455). Left unaddressed, an oxygen sensor fault can reduce fuel economy and damage the catalytic converter — repair costs escalate from an affordable sensor replacement to a catalytic converter replacement that is far more expensive. Misfires that aren’t remedied can cause engine damage and poor drivability, translating to costly repairs and lost time. Evaporative system leaks often begin with inexpensive components but can lead to failed emissions inspections and wasted fuel. Nalley BMW of Decatur in Decatur, GA specializes in accurate code reading and targeted repairs. Our BMW-certified technicians use OEM diagnostics to isolate root causes quickly and explain the repair path, expected costs, and long-term savings. Because we use genuine BMW parts and factory procedures, repairs are engineered to last, preserving performance and resale value.
