Top BMW 6 Series Repairs Explained (and How to Stay Ahead)
Your BMW 6 Series is built to impress, but like any high-performance car, it can experience wear and tear. Here are some of the most common issues BMW 6 Series owners—whether you drive a 640i Gran Coupe, 650i Convertible, or M6—might face, and how you can address them.
1. Engine Oil Leaks
Engine oil leaks are among the most frequent issues for BMW 6 Series owners, whether it’s a 2013 BMW 640i or a 2018 BMW 650i. This usually happens due to worn valve cover gaskets or oil filter housing gaskets. If ignored, these leaks can lead to reduced engine performance or even engine failure.
How to Spot It:
- Dark oil spots under the car
- Burning oil smell
- Oil warning light
Prevent It:
Routine oil changes and inspections are key to catching leaks early. By staying on top of preventative maintenance for BMW 6 Series, you can prevent small leaks from becoming bigger problems.
2. Timing Chain Issues
BMW 6 Series models like the 640i and 650i, especially with high mileage, are prone to timing chain wear. A stretched or worn timing chain can lead to engine misfires or serious engine damage.
Signs to Watch For:
- Rattling noises from the engine
- Check engine light
- Engine misfires
Prevent It:
Routine engine checks during your BMW 6 Series maintenance can catch timing chain wear early. If you hear strange engine noises or see the check engine light, don’t delay—bring your BMW 6 Series in for an inspection.
3. Electrical System Failures
The BMW 6 Series boasts an advanced electrical system, but it can sometimes malfunction. Common issues include problems with the iDrive system, malfunctioning sensors, or battery drainage, particularly in models like the BMW 650i and M6.
How to Stay Ahead of It:
- Keep your software up-to-date
- Replace the battery as recommended
- Address dashboard warning lights promptly
At Atlanta Speedwerks, we specialize in diagnosing and repairing electrical system issues, ensuring your BMW 6 Series stays reliable on the road.
4. Cooling System Failures
A properly functioning cooling system is critical for the high-performance engines in the BMW 6 Series, especially models like the M6. Failures with components such as the water pump or thermostat can lead to engine overheating, which can cause serious damage.
What to Look For:
- Overheating engine
- Coolant leaks
- Temperature warning lights
Prevent It:
Regular coolant checks and flushing the system during BMW 6 Series preventative maintenance can help prevent overheating. If you notice any signs of overheating, bring your BMW 6 Series to a specialist immediately to avoid costly engine repairs.
5. Suspension and Steering Issues
The BMW 6 Series, including the 650i, is known for its smooth handling and luxurious ride. However, suspension components like shock absorbers and control arms can wear out over time, leading to a bumpy ride or steering difficulties.
Common Symptoms:
- Vibrations when driving
- Difficulty steering
- Uneven tire wear
Prevent It:
Regularly scheduled inspections of your suspension system are essential for maintaining ride comfort. If you notice any vibrations or steering difficulties, it’s time to have your BMW 6 Series inspected by our BMW repair specialists in Gainesville, GA.
