P0507 on Volkswagen
Idle Air Control System RPM Higher Than Expected
P0507 on Volkswagen vehicles indicates idle air control system rpm higher than expected. Au7o has documented this code across 2 Volkswagen models — most commonly on Passat, Rabbit. This code means the engine is idling faster than the computer's target idle speed, typically by a set margin such as 200 RPM above commanded. The engine control module manages idle by metering a small amount of air around the throttle plate (via an idle air control valve or electronic throttle), and when it can't bring the RPM down to target it flags this code. The most common real cause is unmetered air sneaking into the intake — a vacuum leak — that the computer can't compensate for. It generally indicates extra air entering the engine or a problem with the idle/throttle control system. Typical repair costs on Volkswagen range from $50 to $800, depending on the specific model and root cause.
Common Causes of P0507
- •Vacuum or intake air leak (hoses, gaskets, intake boot)
- •Dirty or sticking throttle body or throttle plate
- •Faulty or stuck idle air control valve
- •Leaking intake manifold or throttle body gasket
- •Stuck-open PCV valve or cracked PCV hose
- •Dirty mass airflow sensor giving false readings
- •Failing throttle position sensor
- •Leaking brake booster or its vacuum hose
P0507 on Volkswagen by Model
Volkswagen Passat(1 issue)
- PCV Valve/Diaphragm Failure2006-2022
The PCV (Positive Crankcase Ventilation) valve diaphragm in the Passat's 2.0T engine tears or deteriorates over time, causing a significant vacuum leak. This leads to rough idle, misfires, and excessive oil consumption. On TSI engines, the PCV is integrated into the valve cover, making it a more involved repair. The failure can also trigger the check engine light and cause a whistling noise from the engine.
Volkswagen Rabbit(1 issue)
- PCV Valve Diaphragm Failure2006-2009
The PCV (Positive Crankcase Ventilation) valve diaphragm tears, causing a rough idle, oil leaks from various gaskets due to excessive crankcase pressure, and a check engine light. The PCV is integrated into the valve cover on the 2.5L engine.

What does P0507 mean on Volkswagen?▼
P0507 stands for "Idle Air Control System RPM Higher Than Expected." This code means the engine is idling faster than the computer's target idle speed, typically by a set margin such as 200 RPM above commanded. The engine control module manages idle by metering a small amount of air around the throttle plate (via an idle air control valve or electronic throttle), and when it can't bring the RPM down to target it flags this code. The most common real cause is unmetered air sneaking into the intake — a vacuum leak — that the computer can't compensate for. It generally indicates extra air entering the engine or a problem with the idle/throttle control system. On Volkswagen specifically, this code is documented across 2 models.
What causes P0507 on Volkswagen vehicles?▼
