Problems of BMW 428i engine

The 428i engine is an excellent engine with very few flaws. However, it is still plagued by the common issues that haunt every modern-day BMW engine. Here are some of the issues of the BMW 428i engine:-

Cooling System

The water pump and thermostat have long been one of the BMW 5 Series’ Achilles heels. The components have a short lifespan and fail much sooner than they should. The failure of these components accounts for 25% of all mechanical problems in these cars. These elements are essential and. They can cause problems with the rest of the engine if they are ignored.

Fuel Pump

Another component worth paying attention to is the gasoline pump, which has known to fail. As a result, the car’s performance and economy suffer. Limiting power, rough idling, and bad emissions are all problems caused by a defective fuel pump. BMW has already implemented this feature. However, none of the aforementioned issues have been totally resolved.

Low AC refrigerant that makes a noise

A fault that has plagued many 3 series engines and now the 428i as well is that when the AC refrigerant is low the vehicle makes a noise that is not pleasant to hear. This can also cause misdiagnosis and result in wrong parts being replaced without resolution of the problem.

Failing Valve Cover Gasket

The valve cover gasket is a rubber component that prevents engine oil from escaping the engine block and contaminating components it shouldn’t be. If the gasket fails, you may notice pools of engine oil on the ground where your car is in the park, or you may notice the oil covering other engine components during an inspection. This could be hazardous since the oil could leak into the spark plugs, causing misfiring. The valve stem seals are likewise important for maintaining the seal of the intake and exhaust chambers, and they fail as well because they are constructed from the same materials and methods as the valve cover gasket. These parts are created from lower-quality materials than their competitors, and become brittle and snap with time.

Blue smoke pouring out of the exhaust when the automobile is first starting up is a common indicator of failed gaskets. This is the cylinder’s oil burning.

Oil Leakage

This is the BMW 550i’s most serious problem. Unlike its competitors, a combination of poor quality materials and some odd design decisions has resulted in this issue surfacing the most in BMW’s current engine generation. Failure of camshaft seals, valve cover gaskets, and brittle hoses, among other things, can cause leaks. It’s a shame that a vehicle as expensive as the BMW 550i has this problem, which might be caused by the breakdown of any rubber or plastic part in the drivetrain.


To conclude the BMW 428i is an amazing engine with plentiful power and torque figures that will plaster a smile on your face every time you drive it. Apart from the regular BMW engine issues of leaking gaskets, cooling system failures, and the occasional fuel pump issue, this engine is one that will return great performance and efficiency. Regular maintenance and good care of the engine will see it last a long time. The engine is available in a multitude of body styles like Sedan, Coupe, and Cabriolet.
