Common Failure Modes

• Worn plastic gears: A known weak point, especially after 100,000 km (60,000 miles)
• Motor wear or failure: Causing actuator lag or complete shutdown
• Potentiometer faults: Leads to inconsistent throttle input signals
• Connector or PCB issues: Can trigger drivetrain malfunctions and throttle adaptation errors

Failure Symptoms

• Throttle hesitation or surging
• Reduced engine power or limp mode (especially under load)

Service Recommendations

The S85 engine uses two throttle actuators (bank 1 and bank 2). We strongly recommend servicing both units together. To do so, change the quantity to 2 before adding to cart.
