P0507 Audi Code - Idle Air Control System RPM Higher Than Expected
Quick Answer
The Engine Control Module (ECM) controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the electric throttle control actuator. Common causes include Dirty throttle body, Electric throttle control actuator misadjusted or damaged, Faulty Electric throttle control actuator. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0507 Audi Description
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the ECM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan operation, etc.)
What are the Possible Causes of the DTC P0507 Audi?
- Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

Frequently Asked Questions about P0507 Audi Code
1. What does the OBDII code P0507 mean on an Audi?
P0507 indicates that the engine's idle speed is higher than the manufacturer’s specified range, often due to an issue with the idle air control system.
2. What are common symptoms of code P0507 on an Audi?
Symptoms include a higher-than-normal idle speed, rough idling, potential stalling, and sometimes the check engine light turning on.
3. What causes code P0507 on an Audi?
Common causes include a vacuum leak, a malfunctioning throttle body, a dirty or stuck idle air control valve, or issues with the PCV valve or intake manifold gasket.
4. Can a dirty throttle body cause the P0507 code on an Audi?
Yes, a dirty or carbon-clogged throttle body can restrict airflow and result in an elevated idle speed, triggering the P0507 code.
5. How can I diagnose the cause of the P0507 code on my Audi?
Start by checking for vacuum leaks, inspecting the throttle body for dirt buildup, testing the idle air control valve, and scanning for related codes that might provide additional clues.
6. Is it safe to drive my Audi with the P0507 code?
While the vehicle may still be drivable, driving with code P0507 can lead to poor fuel efficiency, potential stalling, and further engine damage if the root cause is not addressed.
7. Can a bad PCV valve trigger the P0507 code on an Audi?
Yes, a faulty PCV valve can cause unregulated airflow into the engine, leading to a higher idle speed and triggering the P0507 code.
8. How do I fix the P0507 code on my Audi?
Fixes include cleaning the throttle body, repairing vacuum leaks, replacing a faulty idle air control valve, or addressing issues with the PCV system or intake manifold gasket.
9. Can resetting the ECU clear the P0507 code on an Audi?
Resetting the ECU may temporarily clear the code, but if the underlying issue isn’t resolved, the code will likely return.
10. How much does it typically cost to repair the P0507 code on an Audi?
The repair cost varies depending on the cause; throttle body cleaning may cost $100–$300, while replacing parts like the PCV valve or intake gaskets could cost more.
