The Quick Answer above is the generic definition. What follows is the model-specific detail for the BMW models that log P0507.
P0507 on BMW: Causes, Symptoms and Fix Cost
P0507 on a BMW 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.
Connect any standard Bluetooth OBD2 adapter to your BMW and Skanyx tells you what P0507 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

BMW 3 Series
2006-2024BMW electronic throttle bodies on N52/N55/B48 can develop carbon deposits. The N52 is especially prone due to its Valvetronic system. Cleaning requires removing the intake boot. BMW's throttle adaptation relearn requires ISTA or BMW-compatible scan tool. DISA valve failure on N52 can also cause high idle.
What causes P0507 on a BMW?
Beyond the generic causes listed on the main P0507 page, these are the patterns noted for BMW models:
How to diagnose P0507 on a BMW 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
