BMW M3 is one of the greatest M cars ever built. On top of that, it is stylish, powerful, and luxurious. Nonetheless, this car comes with several issues that can interfere with its smooth operation. But what are some of the common BMW M3 problems?
Some of the common problems that BMW M3 users should be ready to deal with are a faulty transmission, noisy engine, oil leakage, fuel pump failure, idle control valve failure, throttle body actuators failure, engine failure, and a faulty radiator.
What are the common problems with BMW M3?
The BMW M3 comes with lots of engine problems. One of those issues is making an engine noise. Some users have reported that they heard a loud, metallic ping-pong-like sound coming from the engine. Apart from that, the engine performance reduces significantly.
This issue is common in the 2012 BMW M3. To fix the problem, the engine has to be replaced and it will cost more than $3,000.
Fixing a bad transmission can be very costly. On top of that, it is very cumbersome to fix it. Even though most BMW M3s have transmission problems, this issue is common in the 2005 BMW M3. After driving the car for several miles, the transmission may go into neutral. If this happens, you will see the car’s transmission gear indicator go into neutral.
BMW M3s also experience engine problems. Some of the common engine issues are engine stalling and loss of electrical power. Most of the BMW M3’s engine problems start developing after 70,000 miles. Nonetheless, engine problems are common in the 2008 BMW M3 engine.
In 2019, BMW had to recall 16,641 vehicles because of this issue. So, before you buy a 2008 BMW M3, ensure that this issue was fixed.
This is a common problem across all BMW M3 models. This issue shows up after the car covers over 110,000 miles. Apart from the radiator becoming faulty, the car’s clutch and cooling systems also become problematic. The good news is that most of these parts can be fixed by replacing them.
Idle control valve failure
After putting on several miles, your car’s idle control valve may fail. Some of the signs of a failed ICV are the car running into rough idle or an irregular RPM at idle. Besides, the car may go into limp mode and the check engine light will illuminate on your dashboard.
Ignition/spark plug failure
Like the ICV, ignition and spark plugs also get worn out as you put on several miles. What’s more, they have similar signs as a bad ignition or spark plug. For instance, they cause an irregular misfire in cold weather and are slow to crank. You can fix this issue by replacing the bad ignition coils or spark plugs.
Oil leakage is common in all BMW models. So, the BMW M3 is not an exception. When your BMW M3 hits over 30,000 miles, you should inspect the valve cover before it starts leaking oil. One of the hardest-hit BMW M3 models is the E92 with the S65 V8 engine.
Some of the signs of oil leakage are stains on the driveway, oil buildup, and low oil levels. Replace the bad valve cover.
Throttle body actuators failure
Another common problem that BMW M3s experience is throttle body actuators failure. If you notice your car entering limp mode or the check engine light with throttle body actuator codes coming on, this is a sign of a bad throttle body actuator. This is an easy fix and cheap.
Fuel pump failure
This problem is common in the 2006 BMW M3s. The fuel pump may fail and prevent fuel from reaching the engine or make the fuel volume below. If you have a faulty fuel pump, you will have to replace it.
Is the BMW M3 reliable?
No, the BMW M3 is not reliable. Besides, most reliability rating agencies give BMW M3 a below-average score. This means that you will spend more time in the garage than most of its competitors. On top of that, the cost of spare parts is high, thus increasing the total cost of maintenance.
After how many miles does the BMW M3 start having problems?
If the car is properly maintained, it will last over 150,000 miles without having any major problems. However, you should expect your BMW M3 to have minor issues when it hits over 80,000 miles. Some of the common problems that you will experience early are gasket leakage, gearbox problems, and electronics failure.
