What Problems Does the 2008 BMW M6 Have?
The 2008 BMW M6, while a performance icon, is known for several significant and costly long-term reliability concerns, primarily centered around its S85 V10 engine and SMG III transmission.
Engine (S85 V10) Issues:
Transmission (SMG III) Issues:
Other Common Problems:
Recalls: While specific model-year M6 recalls should always be verified by VIN, the E6x platform was subject to broader BMW recalls, including the widespread Takata airbag inflator recall. Potential issues with brake vacuum pumps or blower motor wiring (fire risk) have also affected some BMW models of this era, though less frequently tied directly to the M6. Always check the NHTSA website using the vehicle's VIN for the most accurate recall information.
Engine (S85 V10) Issues:
- Rod Bearing Failure: This is arguably the most critical and frequently reported issue. Premature wear of the rod bearings can lead to catastrophic engine failure if not addressed preventatively. This is a prevalent concern across all E6x M5/M6 models.
- VANOS Pump Failure: The high-pressure VANOS (Variable Nockenwellen Steuerung - variable camshaft timing) pump is prone to failure, which can result in loss of variable valve timing and potential engine damage.
- Throttle Actuator Malfunction: Failure of the throttle actuators can lead to a "limp home" mode, reduced power, and check engine lights. There are two actuators, and replacement is costly.
- Idle Control Valve (ICV): A faulty ICV can cause rough idling, stalling, or erratic engine behavior.
Transmission (SMG III) Issues:
- SMG Hydraulic Pump/Motor Failure: This is a very common and expensive problem. The hydraulic pump generates pressure for clutch engagement and gear changes. Failure leads to an inability to shift gears, getting stuck in gear, or complete transmission lockout. Often, the relay for the pump also fails.
- Clutch Wear: Due to the automated manual nature and aggressive shifts, the clutch assembly typically wears faster than a conventional manual clutch.
- Gear Position Sensor: Malfunctions can cause incorrect gear indications or difficulty engaging gears.
Other Common Problems:
- Carbon Fiber Roof Clear Coat Delamination: On coupe models, the clear coat on the carbon fiber roof can delaminate and peel over time, especially when exposed to strong sunlight.
- Suspension Components: Wear and tear on bushings, control arms, and adaptive suspension components are expected with age and performance driving, leading to reduced handling precision and comfort.
- Electrical Gremlins: Complex electronics can lead to occasional iDrive glitches, parasitic battery drains, or sensor failures.
Recalls: While specific model-year M6 recalls should always be verified by VIN, the E6x platform was subject to broader BMW recalls, including the widespread Takata airbag inflator recall. Potential issues with brake vacuum pumps or blower motor wiring (fire risk) have also affected some BMW models of this era, though less frequently tied directly to the M6. Always check the NHTSA website using the vehicle's VIN for the most accurate recall information.
How long will the 2008 BMW M6 last?
The 2008 BMW M6 can achieve impressive mileage, often exceeding 100,000 to 150,000 miles, but this is heavily dependent on meticulous maintenance habits and substantial financial investment. Owners who are proactive about addressing known weaknesses, such as preventative rod bearing replacement and monitoring the SMG hydraulic system, report greater longevity. Without this diligence, major engine or transmission failures can occur much earlier, dramatically shortening the vehicle's service life. The long-term durability of the chassis and interior materials is generally robust. However, the specialized powertrain components, particularly the S85 V10 and SMG III, are significant long-term weaknesses requiring continuous and costly attention. This vehicle demands an owner committed to premium upkeep to ensure its continued performance and reliability over time.
What Technology & Safety Features are Included?
The 2008 BMW M6, as a flagship luxury performance coupe/convertible, was well-appointed with technology for its era.
Built-in Tech & Entertainment:
At its core was the second-generation BMW iDrive infotainment system. This system, controlled via a central rotary knob, managed navigation, audio, climate settings, and vehicle diagnostics displayed on a dashboard-mounted screen. While advanced for its time, it could be less intuitive than modern systems. The M6 came standard with a premium Logic7 audio system from Harman Kardon, delivering rich sound through multiple speakers. Bluetooth hands-free phone integration was standard, though audio streaming was not a common feature. An auxiliary input for external audio devices was typically present. Dual-zone automatic climate control ensured comfort for both driver and passenger.
Driver-Assistance Features:
Driver-assistance systems in 2008 were not as comprehensive as today's vehicles. The M6 primarily featured BMW's advanced Dynamic Stability Control (DSC) system, which included an "M Dynamic Mode" (MDM). MDM allowed for a higher degree of wheel slip before electronic intervention, catering to enthusiast driving. Park Distance Control (PDC) with sensors in the front and rear bumpers was a common option, aiding in maneuvering the large vehicle. An optional Head-Up Display (HUD) projected key driving information such as speed, navigation instructions, and gear selection onto the windshield, allowing the driver to keep their eyes on the road.
Safety Features:
Standard safety equipment included a comprehensive airbag system with front, side, and head airbags for occupants. Anti-lock Brakes (ABS), Dynamic Brake Control (DBC) for optimized emergency braking, and the aforementioned Dynamic Stability Control (DSC) were crucial active safety features. High-intensity discharge (HID) Xenon adaptive headlights were standard, offering superior nighttime visibility and swiveling into turns to illuminate the road ahead. Active front headrests were designed to help mitigate whiplash injuries in rear-end collisions. Tire Pressure Monitoring System (TPMS) was also standard.
Crash-Test Ratings:
Due to the specialized, low-volume nature of high-performance luxury vehicles like the M6, dedicated crash-test ratings from independent organizations such as NHTSA (National Highway Traffic Safety Administration) or IIHS (Insurance Institute for Highway Safety) are not typically available. BMW vehicles are generally engineered to high safety standards, and the underlying 6 Series platform would have met stringent European safety regulations of its time.
