Bmw cars are known for their powerful engines and better performance. Like cars that use the BMW B48 engine. Introduced in 2014, it is a turbocharged petrol engine with 4 parallel cylinders and a 2-liter volume.
A popular and best-selling engine that offers a combination of power, quality and efficiency. In fact, the BMW B48 engine, which is a series of performance and medium engines, is used in various Bmw cars, including Series 2, 3 and 4 cars.
However, despite the high performance and efficiency of these engines, problems and failures are inevitable for them.
So we’re going to talk about BMW b48 engine problems in this article. So stay tuned !
BMW B48 engine Common problems
The BMW B48 is one of the best-selling BMW engines with its advanced features and outstanding performance.
But this engine, like any other engine, may have some problems and failures. So since this can affect its performance and capabilities, we’ll look at BMW b48 Common problems in this section.
In fact, our studies show that the BMW B48 engine has a number of common problems, each of which can affect the power and efficiency of this engine.
These common problems include:
1. Coolant leakage and loss
Coolant is a vital element to keep the engine cool. So losing it can have a serious impact on engine performance and health.
Now, among the most common cases of BMW b48 engine problems is the loss of its coolant. This problem occurs when the hose or coupling (connections) of the cooling system fail. In this case, it leads to a gradual leakage of the coolant and is lost.
To understand this problem, you can also understand a number of symptoms based on the occurrence. These symptoms include the lighting of the engine’s high temperature warning light, a decrease in coolant in the radiator tank, the presence of white steam or smoke in the exhaust, overheating of the engine, and the smell of coolant inside the car’s cabin.
However, some preventive measures such as regular check of coolant levels and detection of leaks can prevent this from BMW b48 engine problems.
The periodic examination of connections for leaks and regular replacement of coolant will also be effective in preventing this problem.
2. Oil leakage in the turbo return pipe
Another common BMW b48 engine problems, which may occur in early BMW B48 engine models, is an oil leak in the turbo return tube.
This problem is usually caused by the incorrect installation of an asbestos-free washer in one of the tubes connected to the turbocharger.
It also has symptoms such as oil stains under the car, the smell of burnt oil, and blue smoke from the exhaust. To solve this problem, repairmen or authorized dealers usually reinstall the washer and adjust the direction.
Of course, it is always recommended to replace the gasket, orifice and pipe outlet along with the replacement. In addition, you can always prevent these problems by checking engine oil levels.
3. Exhaustion of bmw b48 engine cooling hoses
One of the most common BMW b48 engine problems is the wear and tear of engine cooling hoses. This problem can occur with the wear and brittleness of hoses, fittings and cooling packages.
Especially in parts that are near and near the hot parts of the engine, such as around the turbocharged or the exhaust manifold, we see it. In fact, the main reason is the use of plastic parts by BMW in these connections, which over time become worn out or fragile due to the extreme heat of the engine.
Now when the hoses are worn out, this causes the coolant to leak, resulting in overheating of the engine and serious damage to it.
To avoid this type of the most common BMW b48 engine problems, you can use a high-quality coolant and always check the level of the coolant.
Of course, regular inspection of parts and timely replacement of them in case of wear and tear will help you avoid such problems.
4. BMW B48 engine water pump failure
Basically, the BMW B48 engine uses a dual cooling system to ensure proper cooling in all conditions. A system that includes two separate water pumps. The main water pump is circulated by the engine’s drive belt and is responsible for cooling the engine.
The secondary electric water pump is also activated after the engine is turned off. Its job is to circulate the coolant around the turbos. Now, one of the most common BMW b48 engine problems is a water pump failure.
When the water pump breaks down, it leads to overheating of the engine, causing a leak of coolant or abnormal noise. Therefore, regular check of the coolant surface and check for leaks or the sound of the water pump operation can prevent damage to the car engine.
5. Engine injector failure BMW b48
BMW B48 engines may also encounter a common injector failure problem in early versions prior to 2019. This failure, one of the most common BMW b48 engine problems, can cause incomplete combustion in the engine. This can occur even when spark plugs and coils are replaced.
There are also several causes of injector failure, including contamination, overheating, wear and tear.
Of course, in BMW B48 engine reinforced models, injector failure is more due to increased heat and pressure. A broken injector in a situation can lead to a cracked piston.
Now to prevent this problem, you have to replace the injectors before they reach 80,000 miles. Regular replacement of gasoline filters and examination of combustion marks will also help maintain the health of the BMW B48 engine.
6. Carbon deposition in bmw b48 engine
The most common BMW b48 engine problems is carbon deposition in the engine. This sediment formation problem is often due to direct fuel injection around air valves and injector nozzles.
Of course, driving short distances that do not give the engine enough time to warm up or using low-quality fuel are other reasons.
Now when the BMW B48 Motor faces this common problem, it is accompanied by symptoms such as reduced power and acceleration of the car, increased fuel consumption, irregular engine start and black smoke from the exhaust.
To prevent this, you should avoid driving very short distances and consume quality fuel. In addition, valve blasting is recommended for cleaning carbon deposits.
Is BMW b48 engine reliable?
In response to the question that Is BMW b48 engine reliable, we should say that yes, the BMW B48 engine is recognized as a reliable engine and was included in the top 10 engines of 2018. With a durable design and the use of high-quality materials, this engine has reliable performance and efficiency. The advantages of the B48 engine include high life expectancy, optimal fuel consumption and powerful performance in various BMW models.
However, some problems have been reported, including the problem of water pump and injector failure in the early B48 engine models.
Also, repairs to the B48 engine may cost a lot of money.
To avoid problems, it is important to carefully check the history of engine maintenance before purchasing and consider models produced after 2019. But in terms of longevity, turbocharger, oil leakage and internal parts, B48 engines can generally be highly durable.
So if you’re going to keep the car for a long time, careful care of the engine and handling its problems will increase confidence. Basically, the B48 BMW engine is a good option for people looking for a BMW car with a reliable engine and good performance.
Summary
In this article, we tried to look at the BMW b48 engine problems and talk about the most common BMW B48 engine problems.
But finally, as a summary, we have to admit that basically, the B48 BMW engine is a significant improvement in reliability for the German automaker’s turbocharged 4-cylinder engines.
The engine uses a new, durable design time chain, more accurate and reliable injectors, a more efficient cooling system, and a sturdy engine block, which has reduced failures and increased engine life.
However, to maintain the health of the B48 engine and avoid BMW b48 engine problems, you should pay attention to maintenance tips such as checking and repairing oil leaks in the turbo return pipe and coolant leaks.
In addition, with gentle driving, regular oil change and timely maintenance, you can enjoy the impeccable operation of this engine for many years.
