BMW 325i lower control arms issue causing car to dart or swerve with code P0411 on BMW 325i

Some BMW 325i owners report experiencing steering issues such as darting or swerving due to problems with the lower control arms. These issues can manifest as clunking noises when driving over bumps, indicating potential wear and tear on the control arms from stress and impacts. Additionally, some owners note that worn lower control arm bushings and ball joints can lead to steering wheel vibrations and wheel shimmy. Since control arms are considered wear-and-tear items, the eventual failure of ball joints may necessitate the replacement of the entire control arm. Furthermore, some owners encounter error code P0411, which indicates a separate issue with the secondary air injection system, often related to the air pump or air pump relay. For a comprehensive repair, it is advisable to address both the lower control arm issues and the specific concerns associated with the error code.
