Toyota Land Cruiser 300: V35A-FTS Twin-Turbo Wastegate Actuator Cold-Start Rattle
V35A-FTS Twin-Turbo Wastegate Actuator Cold-Start Rattle is a common engine fault on the Toyota Land Cruiser 300 on the 2021–2024 cars, and we rate it major. Putting it right costs $300 to $9,500 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 16 documented faults on the Toyota Land Cruiser 300.

What goes wrong
The twin-turbo V35A-FTS engine exhibits a documented rattling or chattering noise at cold start attributed to the turbocharger wastegate actuators vibrating before oil pressure fully builds and the actuator rods seat. The noise typically resolves within 10–20 seconds of start-up. Persistent wastegate chatter beyond warm-up, or rattle under boost, indicates actuator wear or internal wastegate valve looseness, which can progress to boost control problems and ultimately turbocharger failure if left unaddressed.
What you would notice
- Metallic rattle or chatter from low engine area on cold start
- Noise clears once oil pressure builds but may return under boost in worn units
- Boost fluctuation or hesitation under acceleration in advanced cases
- Overboost or underboost fault codes on scan tool in severe cases
- Audible hiss or whistle under load indicating boost path compromise
How to check it
Where to look. Twin turbochargers mounted low on the engine block, V-bank between cylinder banks and on exhaust manifold side
Cold-start the engine and listen for a distinct metallic rattling from the turbo area (lower than injector level). Note whether it clears within 20 seconds. During a test drive, listen for boost-related rattle or hiss under hard acceleration. Request any workshop records noting turbo or wastegate inspection. If a workshop inspection is possible: Check for boost pressure irregularities on a scan tool.
What it costs to put right
$300 to $9,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has any turbo or wastegate inspection or replacement been carried out?”
- “Does the turbo rattle persist after the engine has fully warmed up or under hard acceleration?”
- “Has a scan tool check ever shown boost pressure deviation fault codes?”

How much does it cost to fix on a Toyota Land Cruiser 300?
$300 to $9,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.
Which Toyota Land Cruiser 300 years are affected?
Our research records this fault on the 2021–2024 Toyota Land Cruiser 300. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.
