BMW Z4 (G29) Problems by Year
The latest Z4 (G29), developed alongside the Toyota Supra, returned to a fabric soft-top and shed significant weight, making it much sharper to drive than the E89. Positioned as a dedicated, focused sports car, it offers brilliant B-series engines, particularly the B58 straight-six in the M40i. It is highly praised in the UK for its fantastic interior tech, excellent handling, and robust reliability, suffering mainly from minor software glitches rather than mechanical flaws. It perfectly suits driving enthusiasts wanting a modern, fast, and highly capable roadster with cutting-edge infotainment.

- ✓Check the fabric soft-top for any wear marks or creases, and ensure it opens/closes silently in the claimed 10 seconds.
- ✓Inspect the B48/B58 engine water pump and thermostat area for slow coolant leaks, a common minor issue on modern BMWs.
- ✓Test the iDrive 7 digital instrument cluster to ensure it doesn't freeze or lag, verifying the car has the latest OTA software updates.
- ✓Verify the condition of the large alloy wheels, as the low stance makes them very susceptible to kerbing.
- ✓Ensure the active exhaust valves (if fitted) open and close correctly when switching between Comfort and Sport modes; they can seize with carbon buildup.
- ✓Check the interior trim for squeaks, particularly around the rear bulkhead where the roof mechanism meets the cabin.
