Design: Next-gen CVT with reinforced chain/belt design and dual-range pulley system for improved torque handling (up to 250Nm).

Key Upgrades vs. 018CHA:

• Wider Ratio Spread: 6.5:1 (vs. 5.8:1) for better fuel economy/acceleration.

• Enhanced TCU Logic: Predictive shift mapping based on throttle/G-sensor data.

• Auxiliary Cooler: Standardized to combat fluid breakdown (>230°F triggers limp mode).

Failure Modes:

• Chain Pitting: Contaminated fluid causes micro-wear on pulleys (whining noise).

• Pressure Sensor Drift: False clamping pressure readings (P2817/P17F1 codes).

• Input Shaft Bearing Wear: Leads to axial play → belt misalignment.
