What Happened
The VANOS housing bolts in your vehicle secure the timing system that regulates the airflow in your engine. Over time, these bolts can loosen or even break, which could cause problems with your engine's power.
Risk if Unfixed
If the bolts loosen or break, your engine might lose power or stall while you're driving, making it harder to control your vehicle and increasing the risk of a crash.
Free Fix
Your BMW dealer will replace the VANOS housing bolts for both intake and exhaust VANOS units free of charge. You should schedule the repair as soon as possible to prevent any issues.
