2017 BMW Z4 (E85/E86)
The 2017 BMW Z4 (E85/E86) has an excellent reliability record with no widely reported common faults for this model year period.
Buying Tips for 2017 BMW Z4 (E85/E86)
- Check the soft-top roof operation; the hydraulic pump sits in a drainage channel that fills with water, corroding and destroying the pump.
- Listen for 'ticking' from the N52 engine (2.5i/3.0i) on cold start, often caused by hydraulic lifters not getting enough oil during short trips.
- Inspect the rear coil springs, as they frequently snap on the bottom coils due to corrosion and poor UK road surfaces.
- Test the electric power steering (EPAS) on early models; a 'sticky' feeling dead ahead means the steering column requires replacement.
- Check the cooling system expansion tank and radiator for leaks or bowing plastics, which must be replaced proactively.
- Verify the condition of the front lower control arm bushes; wear here causes heavy tramlining and vague steering.
