Engine and gearbox

The BMW 1 Series from 2014 to 2019 offers a variety of engines, including petrol and diesel options. The 114i, 116i, and 118i petrol engines are generally reliable, but some owners have reported issues with turbochargers and oil leaks, particularly in the 118i models. The diesel variants, such as the 116d and 118d, are known for their efficiency but can suffer from EGR (Exhaust Gas Recirculation) valve failures, leading to performance issues. Gearbox problems have also been noted, especially with the automatic transmission. Some drivers report rough shifting or hesitation, which can indicate wear or electronic faults. Regular maintenance and software updates can help mitigate these issues, but potential buyers should ensure any used model has a full service history.

Electrics and electronics

Electrical issues are among the most common problems reported by 1 Series owners. Problems with the central locking system, dashboard warning lights, and infotainment glitches are frequently mentioned. Specifically, some drivers have encountered “drivetrain warning” messages that can be perplexing, as they may not always indicate a serious issue but can lead to unnecessary concern. Additionally, failing ignition coils have been reported, which can affect engine performance and lead to misfiring. Owners should check the functionality of all electrical components during a test drive, particularly the central locking, lights, and infotainment system.

Body and suspension

The bodywork of the 2014 to 2019 BMW 1 Series is generally well-built, but there are a few areas to inspect closely. Some owners have reported issues with paint quality and corrosion, particularly around the wheel arches and lower sills. Regular washing and waxing can help protect against rust, especially in areas prone to road salt. Suspension problems have also been noted, particularly with the front struts and rear dampers. A knocking noise when driving over bumps can indicate worn suspension components, which may require replacement. Prospective buyers should have the suspension checked during a pre-purchase inspection to avoid costly repairs later.
