P0507 on Audi
Idle Air Control System RPM Higher Than Expected
P0507 on Audi vehicles indicates idle air control system rpm higher than expected. Au7o has documented this code across 1 Audi model — most commonly on SQ2. 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 Audi range from $120 to $350, 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 Audi by Model
Audi SQ2(1 issue)
- PCV / crankcase ventilation valve diaphragm failure causing rough idle and lean-running codes2019-2024
The EA888 2.0 TFSI uses an integrated PCV (crankcase ventilation) valve in the valve cover whose rubber diaphragm and check valve are a known failure point across the engine family. When the diaphragm tears, the seal is lost and unmetered air enters, producing rough idle, possible whistling/screeching from the engine bay, a lean-running condition and sometimes increased oil consumption. It is a recurring, inexpensive-to-diagnose VW-Group fault that affects the SQ2's engine.

What does P0507 mean on Audi?▼
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 Audi specifically, this code is documented across 1 model.
What causes P0507 on Audi vehicles?▼
Common causes on Audi: 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. Specific causes vary by model and year — see the per-model sections below.
