If your BMW shows a p1415 code, it's likely due to a clogged secondary air injection system or failure of the secondary air injection pump. It's important to take your car to a mechanic for a thorough inspection to pinpoint the root cause accurately. If the issue is misdiagnosed, the code will reappear even if manually cleared. Therefore, it's recommended to visit a certified mechanic to address this problem. Refrain from driving extensively before resolving the issue completely. After the repair, drive the vehicle at least 30 miles to ensure the code doesn't come back.
