BMW 7 Series Common Problems
The BMW 7 Series stands as a pinnacle of luxury and performance, offering a driving experience that exudes sophistication and elegance. However, like any complex piece of machinery, the 7 Series is not exempt from encountering certain issues over time.
So, let’s delve into some of the common problems reported by BMW 7 Series owners, providing valuable insights into their causes and suggesting potential solutions.
1. Engine Stutter
A frustrating problem that some BMW 7 Series owners have faced is engine stuttering while driving at high speeds. This issue can manifest as poor acceleration or even a failure to start the car altogether.
Typically, this problem is attributed to a worn-out fuel pump, specifically the high-pressure fuel pump in the 7 Series.
Replacing the fuel pump is the recommended solution to resolve this issue and restore smooth engine performance.
2. Low Oil Pressure
Another frequently reported problem is a sudden drop in oil pressure, often accompanied by the illumination of the engine oil light. This issue is commonly caused by a leak in the oil filter gasket.
If not addressed promptly, the lack of lubrication due to the leak can lead to severe engine damage, potentially resulting in engine failure.
Replacing the oil filter gasket with a new one is crucial to ensure proper oil circulation and prevent further complications.
3. No Parking Brake
Some BMW 7 Series owners have experienced an issue where the parking brake disengages on its own. In most cases, this can be attributed to a worn parking brake actuator, particularly in early models of the 7 Series.
Replacing the actuator is often the solution to rectify this problem.
However, if replacing the actuator does not resolve the issue, it may indicate a fault in the parking brake unit itself, necessitating its replacement.
4. Blurry Cameras
The front and side cameras in the BMW 7 Series may occasionally produce blurry images, causing inconvenience and potentially compromising safety.
This problem has been acknowledged by BMW, and while a definitive solution may not be available at present, it is advisable to keep an eye on any updates or upgraded camera versions released by the manufacturer.

5. Engine Misfiring
Engine misfiring is a troublesome issue that can lead to unstable idling, erratic rev needle movements, and even engine stalling.
Typically, the culprit behind this problem is a faulty coil pack or one of two sensors: the camshaft sensor or the crankshaft sensor.
To address this issue, it is recommended to perform a diagnostic check to identify the specific component causing the misfire.
Once identified, replacing the faulty coil pack or sensor will help restore smooth engine operation.
6. Electric Window Problems
Owners of the BMW 7 Series may encounter difficulties with their electric windows. If you notice a squealing noise when attempting to open or close the window, it is a clear indication of a failing window regulator.
Moreover, you might observe that the windows no longer move up and down as smoothly as they once did.
Replacing the window regulator is the recommended solution to address this issue and restore proper window operation.
7. Air Conditioning Failure
If you find that your BMW 7 Series air conditioning is not functioning properly, particularly if it fails to blow out cold air on the coldest settings, the culprit is likely a fault with the condenser.
To rectify this issue, it is necessary to replace the air conditioning condenser.
By doing so, you can restore the efficient cooling performance of your vehicle’s air conditioning system.
8. Door Locks Failure
A common problem faced by BMW 7 Series owners involves the failure of the door locks to engage when using the key fob, despite being functional when manually locking with the keys.
In most cases, this issue is attributed to faulty door lock motors.
However, it is worth noting that a depleted battery in the key fob could also cause this problem.
Firstly, check the battery in the key fob.
If the battery is not the culprit, replacing the door lock motor will be necessary to resolve the issue.
9. Loss of Brake Power
Some BMW 7 Series owners have reported a significant loss of brake power, resulting in prolonged braking distances. If your 7 Series was manufactured in 2020, it is possible that a faulty integrated brake system hydraulic unit was installed.
To address this problem, the entire hydraulic unit needs to be replaced.
If your vehicle is still under warranty, it is advisable to have the dealer rectify this issue free of charge.
10. Headlights Stuck On
A recurring issue encountered by BMW 7 Series owners is headlights remaining illuminated even when the car is turned off, posing a risk of draining the battery. This problem can be attributed to a malfunction in the automatic headlight system.
Specifically, the light control module may have burnt out due to a power surge.
To address this issue, it is recommended to order a new light control module from our parts page designed for the BMW 7 Series.
With its straightforward installation process, you can easily replace the module and prevent future battery-related complications.
11. Engine Overheating
One significant problem that some BMW 7 Series owners have faced is engine overheating. If you notice that your engine quickly reaches high temperatures and experience a sweet smell inside and outside the car when the engine is running, it’s crucial not to ignore these warning signs.
BMW issued a recall related to this issue, as it stems from the installation of an incorrect engine oil cooler line.
To resolve this problem, you will need to replace the oil cooler line, which is an inexpensive part available in our store.
It’s worth noting that many BMW dealerships will replace the line free of charge.
12. Remote Access Malfunction
If you find that your remote key is no longer functioning correctly, specifically being unable to lock or unlock the doors, or if you receive a notification indicating key battery failure, it’s time to address the issue.
13. Grinding When Braking
Some BMW 7 Series owners have reported hearing a grinding sound when applying the brakes. This issue typically affects vehicles built in January or February 2021 and is caused by poorly produced brake discs.
If your car is not covered by warranty, you can order new brake discs from our parts list, ensuring prompt delivery.
Replacing the faulty brake discs will eliminate the grinding noise and restore smooth braking performance.
By being aware of these common problems faced by BMW 7 Series owners, you gain insight into potential issues that may arise with your own vehicle or become more informed for future reference.
