Bmw 428xi problems

Common Bmw 428xi problems

The BMW 428xi is known for several common problems based on complaints from owners. One of the most frequently reported issues is related to the engine, specifically with accessory belts and pulleys, engine computer, engine mounts, engine knock or ping, fuel leaks, and oil leaks.

Another common problem area for the BMW 428xi is the transmission. While there are no common problems with automatic transmissions in the F32 4 Series, they are extremely sensitive to regular oil (transmission fluid) and filter changes. Cars that do not follow the maintenance schedule are prone to developing a number of problems, including jerky up and downshift.

The crankshaft position sensor is another component that has caused issues in certain F32 4 Series models. Vehicles made between 15th May 2018 and 7th June of 2018 might have a problem with the crankshaft position sensor. When the sensor fails or sends false signals, the engine will enter “limp” mode and limit the power output to prevent potential engine damage.

In addition to these specific issues, there are also minor problems reported by owners, such as adjustable rear suspension, thumping noises, and small problems that can lead to bigger repairs. If you do not wish to have bigger repair costs as these cars age, avoiding models with electronically adjustable suspension is recommended.

The BMW 428xi also has issues with the steering wheel knocking sounds and problems, especially in models with the complex variable sports steering. Higher-mileage vehicles and early models eventually develop oil leaks on different gaskets of the engine, which is to be expected.

The OEM brake system, pads, and rotors/discs are also prone to premature wear, and the Air Conditioning condenser/coolant is easily damaged due to its low, close-to-the-road positioning.

Lastly, the BMW 428xi has problems with the diesel engines (N47 Diesel engines that are present in the F32 4 Series) that have no more timing chain issues as all the F32 models received the updated engine version. However, bigger, 6-cylinder engines are generally problem-free except for clogged EGR and DPF filters, which are prone to clogging if these vehicles make many short trips and city driving.

In summary, the BMW 428xi has several common problems, including engine, transmission, crankshaft position sensor, adjustable rear suspension, steering wheel knocking sounds, oil leaks, brake system, and diesel engine problems. Regular maintenance and checkups are crucial to prevent further damage and keep the vehicle running smoothly.
