P0016 on BMW: Causes, Symptoms and Fix Cost
Quick Answer
High SeverityNot safe to driveBMW
P0016 on a BMW means the crankshaft and intake camshaft on Bank 1 are not in the correct rotational relationship. The ECU detects that camshaft position deviates from what it commanded based on crankshaft position. Causes range from low oil level to timing chain stretch.
Typical repair cost, all makes€50 - €2600
Connect any standard Bluetooth OBD2 adapter to your BMW and Skanyx tells you what P0016 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
2006-2024The N47 diesel (if applicable) and N20/N26 4-cylinder turbos are known for timing chain issues. The N20 chain is on the transmission side of the engine, requiring engine-out or transmission-out removal for replacement, dramatically increasing labour cost. The N52/N55 inline-6 engines have more robust timing chains but VANOS solenoid failures are common and trigger P0016.
What causes P0016 on a BMW?
Beyond the generic causes listed on the main P0016 page, these are the patterns noted for BMW models:

How to diagnose P0016 on a BMW with OBD2
Follow these steps to pinpoint the root cause of P0016:
- Check engine oil level and condition. If low, dirty, or overdue for change, start here. Putting the specified oil back in is a common enough fix to rule out before anything else
- Listen for cold-start rattle from front of engine (1-5 seconds on startup). This is the classic timing chain stretch symptom
- Read live data: check camshaft position deviation from commanded position. Deviation over 5-10 degrees indicates timing issue
- Test VVT solenoid: check resistance with multimeter, inspect mesh screen for debris. A clogged screen is a common quick fix
- If oil change and VVT solenoid check don't resolve, a timing chain kit replacement is likely needed. Have a shop confirm with a timing chain wear measurement
