Buying Tips for 2012–2016 BMW Z4 (E89)

  • Test the folding metal roof multiple times; listen for grinding or hesitation, and check the boot for water ingress, which destroys the hydraulic pump.
  • On early 35i models (N54 engine), check for long cranking times or check engine lights, pointing to failing high-pressure fuel pumps (HPFP) or injectors.
  • Inspect the 19-inch alloy wheels (if fitted) for cracks; the firm suspension and run-flat tyres make them highly prone to fracturing.
  • Check the front suspension for knocking, particularly the tension strut bushes which wear quickly under the weight of the heavy nose.
  • Verify the condition of the rear taillights; the LED indicator strips frequently fail and require a complete cluster replacement.
  • Listen to the turbocharger wastegates on N54 engines for a distinct 'rattle' when lifting off the throttle, requiring turbo replacement to fully cure.
