The E89-generation BMW Z4 (produced from 2009–2016, with 2016 being one of the last model years) is a hardtop convertible that balances classic two-seat roadster enjoyment with modern comfort. This compact, practical guide covers what owners like about the car, common complaints you’ll hear in owner forums and service shops, and real-world tips for buying and owning an E89 Z4.
What Owners Like
- Pure driving feel: Owners praise the Z4’s steering and chassis balance. It feels engaging and precise for a grand tourer, especially with the six‑cylinder engines.
- Retractable hardtop: The one-piece folding roof offers coupe-like security and quiet with the top up, and converts quickly for open-air driving without the fabric-top drawbacks.
- Compact practicality: Two seats and a usable trunk (better than many convertibles) make it practical for weekend trips and everyday use.
- Engine choices: The two main powertrains— a 2.0L turbo four and a 3.0L turbo inline‑six (in higher trims)—offer a range from economical to very quick. The six-cylinder variants are especially applauded for their smooth power delivery and soundtrack.
- Styling: Many owners love the long-hood, short-deck proportions and the refreshed styling after the mid-cycle update.
- Comfort and features: For a sports car, the E89 is relatively comfortable for longer trips and can be well-equipped with options like active suspension, upgraded audio, and navigation.
Common Complaints & Known Issues
Owning any German sports car comes with joys and costs. Here are recurring issues you should know about:
- Engine-related problems: Direct-injection engines used in the Z4 (both the four and six-cylinder variants) can suffer carbon buildup on intake valves, especially on six-cylinder models that originally used intake port injection less frequently. Some earlier sixes have known high-pressure fuel pump and turbo wastegate concerns if they’ve been modified or not well-maintained.
- Oil leaks: Valve cover gaskets, oil filter housing gaskets, and other seals can start to leak with age. On the six‑cylinder engines, oil leaks around the turbo and oil cooler hoses are also commonly reported.
- Cooling system items: Thermostats, water pumps, and electric cooling fans are wear items on these cars and can fail—sometimes prematurely. Cooling system maintenance is essential to avoid overheating and more serious engine damage.
- Roof mechanism and seals: The retractable hardtop is generally durable, but seals and the hydraulic/actuator elements can wear. Leaks and wind noise are commonly cited in older cars.
- Electronics and iDrive quirks: Infotainment glitches, door module faults, and aging sensors can cause intermittent issues. Many owners report minor annoyances rather than show-stopping failures.
- Suspension bushings and shocks: After 60–100k miles, bushings, bearings and dampers may need replacement—especially if the car has been driven hard or on rough roads.
- Expensive consumables: Brakes, tires (often staggered sizes), and specialized fluids can be pricier than a compact sedan.
Real-World Tips for Buying
When shopping for a 2016 Z4 (or any E89), these practical checks will save you money and headaches:
- Service history matters: Look for consistent BMW service records or reputable independent shop invoices. Regular oil changes, cooling system work, and timing/valve cover/gasket repairs reduce future surprises.
- Inspect the roof: Cycle the hardtop several times (from cold and warm) and listen for unusual noises. Check trunk area seals and the rear parcel area for water staining or dampness.
- Check for oil leaks and smoke: Visually inspect under the car and around the engine bay. A small oil residue is common, but heavy leaks or blue smoke on startup are red flags.
- Scan for codes: Have a pre-purchase OBD scan performed. Pending or stored codes—especially engine or transmission faults—should be evaluated by a mechanic.
- Look for tuning and mods: High-performance variants are commonly tuned. Tuning can mean more performance, but also a potential increase in wear on turbos, HPFP, and drivetrain parts. Get documentation and, if possible, an owner’s log of dyno/tune work.
- Test drive thoroughly: Listen for clunks from suspension, rattles from the roof, and responsiveness of the steering and throttle. Drive with the top up and down.
- Professional inspection: If you’re serious, a BMW specialist pre-purchase inspection is worth the cost—especially for identifying engine, turbo, and cooling-system issues.
Practical Ownership & Maintenance Tips
- Follow proactive cooling system maintenance: Replace the water pump, thermostat, and hoses preventatively around 60–100k miles. Using OEM or high-quality aftermarket parts helps longevity.
- Address oil leaks early: Replacing valve cover and oil filter housing gaskets when you see seepage prevents bigger headaches later.
- Carbon and ignition maintenance: If you own a six-cylinder Z4 with direct injection, consider intake cleaning (walnut blasting) if you see rough idle or misfires. Replace coils and plugs on the manufacturer schedule or sooner if misfires appear.
- Care for the roof seals: Clean and condition seals; keep the roof mechanism lubricated per shop recommendations. Fix leaks promptly to avoid interior and electrical damage.
- Budget for tires and brakes: Performance tires and brake pads/rotors are consumables—prioritize quality to maintain handling and safety.
- Use decent fuel and fluids: Higher-output engines appreciate premium fuel. Use the recommended viscosities and BMW-approved coolant and oil.
- Keep suspension healthy: Replace worn bushings and dampers in matched sets to preserve handling character.
Final thoughts
The 2016 BMW Z4 (E89) is a rewarding roadster that offers a great blend of driving engagement, convertible practicality, and everyday usability. Buy carefully—pay attention to service history, roof condition, and engine health—and stay proactive with cooling and gasket maintenance. With sensible upkeep, the Z4 remains a charismatic, fun-to-drive car that’s practical enough for regular use and thrilling enough for weekend drives.
FAQs
Q: Which engine should I choose—2.0 turbo four or 3.0 turbo six?
A: The 2.0L four is lighter, efficient and plenty fast for most drivers. The 3.0L six delivers smoother, stronger midrange and a more classic BMW sound—choose it if you want more performance and are willing to pay a bit more for maintenance and fuel.
Q: Are roof problems common?
A: Not pervasive, but seals and actuators age. Check operation, listen for odd noises, and verify there are no leaks. Address seal or motor issues quickly to avoid water damage.
Q: What major repairs should I expect?
A: Expect items typical for an aging BMW sports car: cooling system jobs (water pump/thermostat), gasket replacements (valve cover, oil filter housing), suspension bushings, and possible intake cleaning or ignition service on direct-injection engines.
Q: Is this a good car for daily driving?
A: Yes—many owners use the Z4 daily. It’s comfortable enough for commuting and practical for errands, but be prepared for slightly higher maintenance and running costs than a mainstream compact car.
Q: Any dealbreakers to avoid?
A: Heavy track use without service history, extensive tuning with no receipts, unresolved coolant/overheating history, or persistent oil smoke/leaks—these all warrant caution or avoidance unless priced accordingly and repaired.
If you’re considering a 2016 Z4, a careful inspection and a willingness to follow a preventive maintenance plan will reward you with years of open-air driving enjoyment.
