BMW 6 Series (F12/F13/F06) Problems by Year

The F-generation 6 Series is a beautiful and refined grand tourer that corrected the controversial styling of its predecessor, culminating in the highly desirable four-door Gran Coupe (F06). Positioned as a high-end luxury alternative to the Porsche Panamera or Mercedes CLS, it offers immense motorway capability and a stunning interior. Running costs in the UK are predictably high, particularly for the thirsty petrol V8s and the complex adaptive suspension systems. It suits wealthy executives or long-distance commuters wanting huge road presence, comfort, and undeniable style.

Buying Tips for the BMW 6 Series (F12/F13/F06)

  • On the 640d (N57 diesel), check for timing chain rattle on cold startup; a stretched chain requires a costly engine-out replacement.
  • Inspect the twin-turbo V8 (650i) for extreme oil consumption and leaking coolant lines in the V-valley of the engine.
  • Test the frameless door windows; they should drop slightly to clear the seals. If they stick, wind noise and water leaks will follow.
  • Check the massive alloy wheels (often 20-inch) for cracks; the low-profile run-flat tyres transfer huge impacts directly to the rim.
  • Verify the condition of the adaptive dampers; leaking shocks will ruin the ride quality and cost a fortune to replace.
  • Ensure the soft-close doors function smoothly without bouncing back, as the latch mechanisms wear out over time.
