P0507 on Volkswagen: Causes, Symptoms and Fix Cost
Quick Answer
Moderate SeveritySafe to drive (short-term)Volkswagen
P0507 on a Volkswagen 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.

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
