Great question. On the Audi Gen 3 1.8 TFSI CJEB, the intake camshaft VVT (variable valve timing) values depend heavily on engine load, RPM, and ECU request. Here's a rough guideline for intake camshaft advance (in degrees of crankshaft) under normal operation:
Normal VVT Intake Advance Values (Approximate)
Engine Load RPM Range Intake VVT Advance (° Crank)
Idle ~800 0° to 10°
Light Load 1500–2500 10° to 20°
Light Load 3000–3500 15° to 25°
Medium Load 3000–4000 20° to 35°
Heavy Load 4000–6000 40° to 60°
WOT (High RPM) 5000–6500+ Up to 60°
Notes:
60° advance is typically only requested under high load / high RPM conditions for max performance.
Light throttle at 3000 RPM should usually be around 15–25° advance, not 60°.
If you're seeing 60° under light load at 3000 RPM, and it’s causing misfires, it’s likely a fault:
ECU commanding wrong angle (mapping issue or sensor fault)
Intake camshaft stuck advanced (mechanical or OCV issue)
Oil control valve (N205) stuck open
Timing issue or incorrect adaption
