One of the worst problems with the BMW N47 Engine (previous version of BMW N47T Engine) is that it’s more than the size of the timing chain, which causes the part to break down early. If this happens, drivers may notice sounds like a metal rattle from the car. This sound comes from the engine and indicates that the timing chain is more abrasive than the size.
Is the N47T reliable?
You should know that all N47 engines, even if they are modified with the best parts, end up having problems. Later engines in the BMW have a longer life and durability than in previous models.
How long does the BMW N47 Engine last?
200,000 kilometers for a BMW can be imagined with this engine. But the car may also be able to travel up to 500,000 kilometers with this engine.
When did BMW repair the N47 Engine?
Important problems that the N47 time chain had were until 2011. But then BMW tried to largely mitigate the problems.
Keep in mind that after this time, there were also problems with the time chain, which was much less than before. In 2014, BMW replaced the B47 engine with the N47, which used the same chain, but did not have the famous N47 problems to a large extent.
Which BMW engine has a timing chain problem?
Early destruction of the time chain has been a common problem in many BMW four-cylinder engines over the past decade.
Some of the most important problems with engines are:
N20 4-cylinder turbo (F30 328i, F22 228i, X1 sDrive 28i, etc.) N26 4-cylinder turbo (F56 Mini Cooper S)
Is the N47 really good ?
The N47 offers a lot of power and offers an abundance of torque at the beginning of the Far Range. Despite its many capabilities, the N47 has been heavily criticized for its concern about time chain capability.
You should know that by 2011, the engine was highly susceptible to the catastrophic destruction of the time chain.
What is the difference between N47 and N47T Engine?
47T is an N47 update and modification that fixes Time chain errors. The first modification and update was made in 2009, which was an attempt to cut the chains. To do this, they moved the crankshaft because the chain gear has a timing and can be changed.
This reduced wear. But despite this reform, its change was not so much applied to solving this problem. But in the 2014 production machines, there was a chain failure.
The second modification and update was carried out about 5 years ago, and many cars were equipped with new guides, chains and traction, and the quality went much higher. Some changes partially eliminated the previous problems.
BMW is looking to update the engine two to three times between 2007 and 2015 for the BMW N47. Due to the fact that this engine was used a lot in this car, the problems with the time chain were not very common.
But it ends up being very expensive to change. Because the chain is on the back of the engine.
What is the common problem of N47?
Wastegate turbo problems and increased fuel consumption are other defects that N47 engines have and related to turbo waste.
The lack of lubrication that must be done first in the waste spring has caused its rapid destruction and led to partial or complete opening of the wastegate door.
What does a wastegate do on a turbo?
The waste removes the exhaust gases from the turbocharger to adjust the turbine speed and increase the pressure.
Choosing the right waste size depends on the amount of exhaust exhaust, the amplification force, and the amount of gas the turbo needs to exhaust to achieve that Amplification force.
How much Power is N47?
Unfortunately, 350 horsepower is the power of the N47 engine without important and serious parts such as the performance camshaft and so on, which is beyond the ability of the N47 engine.
310 to 350 is the maximum horsepower rate at best for the N47 engine.
How to identify that the Engine is N47?
The most convenient way to diagnose is as follows:
Exhaust pipe. Machines with an elliptical exhaust pipe have an N47 engine and a DPF. Older cars with the M47 engine have a narrower exhaust pipe that rotates towards the ground and does not have a DPF.
Why does the N47 timing chain break?
As you know, the N47 engine is known for destroying the time chain associated with the construction of the crankcase gear.
However, by searching Autotrader, there are many examples of mileage cars (Series 1, 3 and 5) that are more than 100,000 miles and up to 170,000 miles.
When should we replace the N47 Timing Chain?

Does the N47 have a rotary Flap?
This kit allows you to remove problematic Rotary flaps, known as deterioration and eventually disintegration. This is eventually sucked into the engine, which is often accompanied by damage and bad things.
Why does the BMW timing chain fail?
The causes of time chain problems are given below:
Using the wrong oil is one of the most important causes of time chain failure. Using the wrong engine oil in your BMW can cause a variety of problems.
Nevertheless, the time chain is one of the main parts that is affected. If you use inappropriate oil, it will most likely wear out faster.
