What to look out for

The checks worth doing on a BMW Z4 before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Cycle the roof fully at least twice, listening for hesitation, and check the boot floor and roof storage area for hydraulic oil stains or damp.

    See why

    Retractable hardtop hydraulic and sensor failures (E89)

    The E89's two-piece folding metal roof depends on a hydraulic pump, multiple rams, solenoid valves and position sensors; with age the system develops leaks, worn microswitches and relay/solenoid faults that leave the roof stuck half-open. Diagnosis is specialist work and hydraulic component replacement gets expensive quickly. Water ingress into the boot from perished roof seals is a related complaint.

    What you would notice

    • Roof stops mid-cycle or refuses to latch
    • Grinding or hesitation during operation
    • Hydraulic fluid staining in the boot area
    • Wet boot carpet after rain

    Typically $1,000–$4,000 to put right.

01N54 high-pressure fuel pump, injector and wastegate problems (sDrive35i/35is)

Cold-start the car and listen for wastegate rattle and rough running.petrol2009–2016Engine
CommonEngine $1,500–$5,000 to fix

Can't confirm for this car

The twin-turbo N54 in the sDrive35i inherits that engine's full catalogue: high-pressure fuel pump failures (long cranking, misfires, limp mode), leaking or stuttering piezo injectors, and turbo wastegate wear announced by a metallic rattle at cold idle. Early pumps should have been replaced under BMW's extended programmes in some markets, but NZ/AU-delivered and imported cars need the history checked. Individually manageable, collectively these make a neglected 35i the expensive Z4 to own.

Symptoms to notice

  • Long cranking before start
  • Misfires or stutter in the first 30 seconds from cold
  • Metallic rattle from the turbos at idle
  • Limp mode with fuel-pressure fault codes

What to check

Cold-start the car and listen for wastegate rattle and rough running. Ask a BMW specialist to check via the VIN which HPFP revision is fitted and scan for fuel-pressure and misfire codes.

Where to look: HPFP and injectors on the engine; turbos and wastegates under the exhaust manifolds

Parts involved: High-pressure fuel pump, Turbocharger, Fuel injector.

Ask the seller

  • “Has the high-pressure fuel pump been replaced, and with which revision?”
  • “Have any injectors been replaced?”
  • “Does it rattle at cold idle?”

02Electric water pump failure (N52 3.0si/sDrive23i/30i, also N54)

Ask when the electric water pump and thermostat were last replaced - on a 100,000 km+ car with the original pump, budget for it.petrol2006–2016Cooling
CommonCooling $1,500–$3,200 to fix

Can't confirm for this car

The N52 and N54 use a Pierburg electric water pump that commonly fails electronically from around 80,000-130,000 km, often with little warning, causing overheating and limp mode. On the E89 the pump is awkward to reach - workshops often remove the steering rack for access - so labour is a big share of the bill. Many owners replace it preventatively with the thermostat.

Symptoms to notice

  • Cooling fan running at full speed from cold start
  • Temperature warnings or limp mode
  • Whirring noise from the pump area
  • Speed-deviation fault code for the coolant pump

What to check

Ask when the electric water pump and thermostat were last replaced - on a 100,000 km+ car with the original pump, budget for it. Have codes scanned for coolant pump speed deviation faults.

Where to look: Front lower side of the engine, behind the steering rack on E89

Parts involved: Water pump.

Ask the seller

  • “Has the electric water pump been replaced?”
  • “Has the car ever overheated or gone into limp mode?”

01Electric water pump connector short circuit, fire-risk recall REC-006063 (Z4 N20 turbo petrol)

petrol2011–2016Electrical
RareElectrical $0–$1,800 to fix

Does not apply

On the N20 2.0 litre turbo four-cylinder (Z4 sDrive20i/sDrive28i), oily blow-by liquid from the crankcase ventilation system can collect on the intake air hose and drip onto the electric water pump's plug connector. If liquid gets into the connector it can short circuit, overheat and in rare cases start an engine bay fire. BMW Australia recalled these cars in August 2024 (REC-006063, campaign 0011800700; US campaign 24V608) to inspect and if needed replace the pump and connector and fit a protective shield, free of charge. Ask for proof the recall work has been done.

Symptoms to notice

  • Coolant temperature or engine overheating warning
  • Drivetrain malfunction or reduced power message
  • Burning electrical smell from the engine bay
  • Electric water pump stops working and the engine overheats

What to check

Ask the seller or a BMW dealer to confirm by VIN that recall REC-006063 (water pump plug connector and shield) has been completed, and ask for the invoice or service record. With the bonnet open, use a torch to look around the front of the engine for oily residue, scorched plastic or melted wiring, and smell for burnt electrical insulation after the test drive. Watch the temperature and warning lights during a 20 minute drive. If a workshop inspection is possible: have the electric water pump connector checked for oil contamination or corrosion and confirm the shield is fitted.

Where to look: Front of the engine, low down: the electric water pump and its plug connector below the intake air hose

Parts involved: Water pump, Turbocharger.

Ask the seller

  • “Has the water pump connector recall (REC-006063) been done, and can I see the paperwork?”
  • “Has the water pump ever been replaced?”
  • “Has the car ever overheated or shown a coolant warning?”

03Soft-top roof motor failure from water ingress (E85)

Operate the roof at least three times in a row.petrol2003–2008Electrical
CommonElectrical $600–$2,800 to fix

Does not apply

The E85's electro-hydraulic roof motor sits low behind the cabin where blocked drainage holes let rainwater pool and flood it, killing the motor. Roof microswitches and the roof module also fail, leaving the top stuck. Many owners relocate the replacement motor higher or into the boot as a permanent fix; keeping the drains clear prevents the problem entirely.

Symptoms to notice

  • Roof will not open or stops mid-cycle
  • Whirring pump noise but no roof movement
  • Damp carpet or musty smell behind the seats
  • Roof works only intermittently after rain

What to check

Operate the roof at least three times in a row. Ask whether the drains have been cleaned or the motor relocated. If a workshop inspection is possible: Lift the carpet/trim behind the seats to feel for damp and look for water staining around the motor well.

Where to look: Roof motor in a well behind the seats/rear bulkhead; drain holes either side

Ask the seller

  • “Has the roof motor been replaced or relocated?”
  • “When were the roof drains last cleared?”

04Infotainment and electrical gremlins - iDrive freezes, Harman Kardon amp cut-out, headlight condensation (G29)

During the test drive run the stereo, navigation and phone pairing the whole time.petrol2019 onwardElectrical
OccasionalElectrical $300–$2,500 to fix

Does not apply

Early G29s show a cluster of electrical niggles: the iDrive display can freeze or reboot, a supplier fault in 2021-era Harman Kardon amplifiers caused audio to cut out entirely, and some cars develop headlight condensation. Most were fixed under warranty via software updates or replacement modules, but on out-of-warranty cars an amplifier or headlight is a real bill. These do not affect drivability but are annoying and worth using in negotiation.

Symptoms to notice

  • iDrive screen freezing or rebooting mid-drive
  • Audio system dropping out completely
  • Moisture fogging inside headlight lenses
  • Bluetooth/CarPlay disconnects

What to check

  1. During the test drive run the stereo, navigation and phone pairing the whole time.
  2. Inspect both headlights for internal fogging after washing the car or on a cold morning.
  3. Confirm software is up to date at a dealer.

Where to look: Dashboard infotainment, boot-mounted amplifier, headlight units

Ask the seller

  • “Has the Harman Kardon amplifier ever been replaced?”
  • “Are all software updates current?”
  • “Any headlight condensation history?”

01Steering tie rod safety recall (early G29, MY2018-2019 build)

Run the VIN through a BMW dealer or the manufacturer's recall checker to confirm the tie rod recall has been completed.petrol2019–2020Suspension
RareSuspension $0–$1,500 to fix

Does not apply

BMW Australia recalled early-build G29 Z4s (along with G20 3 Series and X3M/X4M) because the steering track rods could be damaged by high temperatures and vibration and ultimately break, impairing steering control. The same defect drove recalls of the Z4 and its Toyota GR Supra twin in other markets. The fix is free replacement of both tie rods at a BMW dealer - the buyer's job is simply to confirm the work was done.

Symptoms to notice

  • Usually none before failure
  • Clunk or vagueness from the front steering
  • Steering pull or uneven front tyre wear

What to check

Run the VIN through a BMW dealer or the manufacturer's recall checker to confirm the tie rod recall has been completed. For NZ-imported cars check the recall status was actioned in the source market.

Where to look: Steering tie rods between the steering rack and front wheels

Ask the seller

  • “Has the steering tie rod recall been carried out on this VIN?”
  • “Is there dealer paperwork showing the recall completion?”
Fluid leaks1

01Engine oil leaks - valve cover and oil filter housing gaskets (G29 B48/B58)

With the bonnet open after the test drive, look and sniff along the valve cover edges and oil filter housing for wet residue.petrol2019 onwardFluid Leaks
OccasionalFluid Leaks $600–$1,800 to fix

Does not apply

The most commonly reported mechanical complaint on the G29 is engine oil seepage, typically from the valve cover gasket or oil filter housing area as the B48/B58 engines age. Leaks start as a hot-oil smell and light misting before dripping onto the exhaust or belt path. Gasket replacement is routine work but B58 access adds labour.

Symptoms to notice

  • Hot oil smell after a drive
  • Oil misting or weeping down the side of the engine
  • Drops on the driveway
  • Low oil warnings between services

What to check

With the bonnet open after the test drive, look and sniff along the valve cover edges and oil filter housing for wet residue. Check service records for gasket work.

Where to look: Top and front side of the engine under the bonnet

Parts involved: Rocker / valve cover.

Ask the seller

  • “Have any oil leaks been repaired?”
  • “Does the car use oil between services?”
