What does this code mean?
Actual idle speed is higher than the controller expects under the monitor's conditions. The code does not identify an idle-air valve as a failed part; electronic-throttle vehicles may use a different idle-control architecture. The cited Volkswagen bulletin also addresses idle-diagnostic software strategy.
Sources and interpretation [1]
A code identifies a detected condition, not a part that must automatically be replaced.
Before replacing a part
Compare desired and actual idle speed with temperature and electrical loads recorded. Check related pressure/air-flow codes and the applicable software bulletin. Do not adjust a throttle stop or apply a relearn procedure from another vehicle.

Can I keep driving?
A code alone cannot establish whether driving is safe. A flashing malfunction light, severe shaking, overheating, oil-pressure warning or loss of braking or steering needs prompt attention. Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
