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 2 Audi models — most commonly on S7, S8. 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.
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 S7(1 issue)
- 4.0 TFSI Crankcase Breather Leak With Warm-Idle Whistle (TSB 2040644/3)2013-2016
Audi TSB 2040644/3 covers 2013-2016 S7 4.0 TFSI vehicles with a warm-idle metallic whistle or grinding sound, an intermittent MIL, and P2279 or P0507 caused by a leaking crankcase-breather pressure-regulating valve.
Audi S8(1 issue)
- 2013-2016 S8 Warm-Idle Whistle from Crankcase Breather Leak - Diagnosis Required2013-2016
Audi TSB 2040644/6 covers a metallic whistling or grinding sound at warm idle, a sporadic MIL and possible P2279 or P0507 on 4.0 TFSI vehicles. A leak in the crankcase breather pressure-regulating module can cause the condition. Audi’s labor table explicitly includes the S8.

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 2 models.
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.
