BMW 650i 6-Series is a powerful and luxurious gran coupe with a handsome exterior. This car also comes with the latest technologies and it has a spacious cabin and cargo area. However, it also has several issues, such as using excess oil, turbo failure, fuel pump issues, electrical faults, and much more.
So, before you spend a fortune on this luxurious and sporty ride, you should be ready to deal with the above issues over the years. Besides, this car is not very reliable, meaning that you may spend more time in the garage compared to the BMW 3-Series and 5-Series.
What are the common with the BMW 650i?
Consumes a lot of oil
One of the main problems that BMW 650i owners are likely to face is excess oil consumption. This issue happens under certain conditions. What’s more, it is more rampant on BMW 650i models with the N63 4.4-liter V8 powertrain.
One of the things that are suspected to cause excess oil usage is the heat in the engine bay that exploits the fragility of parts in the crankcase, making the car utilize excess oil. Some of the signs of excess oil usage include blue smoke coming from the exhaust or check engine light coming on. To rectify this issue, you may have to replace the faulty parts.
Fuel pump problems
Another common problem that BMW 650i users normally face is fuel pump failure. However, this issue is common on 2011 BMW 650i models with a V-8 engine. It happens because of a faulty valve that controls the amount of fuel that goes into the high-pressure fuel pump.
If the valve is faulty, the engine’s power output will be decreased and an engine malfunction may take place. To fix this problem, you may have to replace both the control valve and the high-pressure fuel pump.
Problem with door lock sensors
This problem is common in most BMW cars. The BMW 650i is not an exception. Door lock sensors fail because of broken connections within the door panel or lock system. To fix the issue, you may have to buy a new door lock system.
Failing ignition coils
The main reason why some BMW 650i models have a failing ignition coil is because of an overvoltage reaching the coil from a bad spark plug or plug wire. If the ignition coil fails, you will have no choice but to replace it.
Water leaking into the boot
Some BMW 650i users have also reported water leaking into the boat. The main culprit behind this is a failing boot seal. If the boot seals fail, water will leak into the boot and wet your things. This is so dangerous as the water can get in contact with the electrical in the boot and cause havoc.
Convertible roof problems
Not all the BMW 650i 6-Series have enclosed gran coupes. They also have convertibles. So, if you intend to pick the convertible, one of the common issues that you should expect to face is a roof that’s failing to close. This happens because of a failing position sensor. And if you see a red light on the dashboard, this will be confirming the failed sensor.
Electrical faults
Electrical faults are another common issue with all BMW models. When it comes to the BMW 650i, this issue is more rampant on the 2010 and 2011 models. One of the common electrical faults on the 650i is a potential short circuit on the water pump. If not properly managed, this can cause an under-bonnet fire.
Headlight condensation
After using your BMW 650i 6-Series for some time, you may notice that your headlight has condensed. This is a common occurrence on this model and you should monitor your headlights closely. If the condensation is not because of the extreme weather, then you will have to replace the headlight or it may damage the wiring.
