Common issues with the BMW F30 330d often involve frequent replacement of EGR valves and steering racks. When test driving, pay attention to any clunks from the front on rough surfaces or from the steering wheel when turning it without the engine running. A malfunctioning EGR valve can disrupt the flow and function of the EGR system, resulting in performance issues like decreased power, slower acceleration, and lower fuel efficiency. EGR valves may get stuck in either an 'open' or 'closed' position due to the accumulation of soot particles, carbon deposits, and fuel residue.
There are issues with the alternator, engine, electrical system, transmission, brakes, seat belts, airbags, and suspension in the 2019 BMW F30 330d.
