P0507 means the engine is idling significantly higher than the ECU expects. Normal idle is typically 600-800 RPM. When the ECU detects idle speed consistently above its target by 200+ RPM and cannot bring it down, it sets P0507. The most common causes are vacuum leaks, dirty throttle body, or a stuck idle air control valve.

What does P0507 mean on a Volkswagen?
Volkswagen Golf
2005-2024VW TSI engines use electronic throttle and are prone to carbon buildup on the throttle body due to direct injection and PCV blow-by. The EA888 PCV diaphragm failure can cause a massive vacuum leak triggering P0507 alongside P0171. VW's throttle adaptation relearn requires VCDS or OBDeleven scan tool.

How to diagnose P0507 on a Volkswagen with OBD2
Follow these steps to pinpoint the root cause of P0507:
- Check for vacuum leaks: listen for hissing sounds, spray brake cleaner around intake manifold gaskets and hoses while engine runs. RPM change indicates a leak
- Inspect throttle body for carbon buildup. Remove intake boot and look inside. Clean with dedicated throttle body cleaner if dirty
- Check idle RPM with scan tool live data. Note if it drops to normal range after the throttle body cleaning
- If throttle body is clean and no vacuum leaks, test the IAC valve (if equipped). Command it open/closed with scan tool and listen for operation
- Check coolant temperature sensor reading vs actual temperature. A faulty sensor reading cold will cause the ECU to command high idle
- After any repair, perform an idle relearn procedure per manufacturer instructions

FAQ: P0507 on Volkswagen
Why does my car idle so high?
The most common cause is a vacuum leak letting extra air into the engine, or carbon buildup preventing the throttle plate from fully closing. The ECU tries to compensate but can't bring RPM down to target.
Can I fix P0507 by cleaning the throttle body?
Often, yes. Carbon buildup on the throttle plate and bore prevents it from closing fully, keeping idle high. A 15-minute cleaning with dedicated throttle body cleaner resolves P0507 in many cases.
Is high idle dangerous?
Not dangerous, but annoying and wasteful. On automatic transmissions, high idle causes harsh gear engagement. It wastes fuel and can accelerate wear on engine mounts and transmission components.
Do I need to do an idle relearn after fixing P0507?
Usually yes. After cleaning the throttle body or replacing the IAC valve, the ECU needs to relearn the correct idle position. Some cars do this automatically over a few drive cycles. Others require a specific procedure with a scan tool.
