BMW E46 Due for Service: What You Need to Know
Your BMW E46 is a meticulously engineered machine that requires regular maintenance to stay in peak condition. If your E46 is due for service, you might be wondering what to expect. This comprehensive guide will walk you through everything you need to know about keeping your BMW E46 running smoothly.
Understanding BMW E46 Service Intervals
BMW recommends following a Condition Based Service (CBS) schedule for the E46 generation. This system utilizes sensors and algorithms to determine when specific maintenance tasks are required based on actual driving conditions. However, if your E46 doesn’t have CBS or you prefer a more traditional approach, you can adhere to these general guidelines:
- Oil Change: Every 3,000 miles or 3 months, whichever comes first, using synthetic oil.
- Air Filter: Every 15,000 – 20,000 miles.
- Cabin Air Filter: Every 15,000 – 20,000 miles.
- Spark Plugs: Every 30,000 – 40,000 miles, depending on the type of spark plugs installed.
- Coolant Flush: Every 2 years.
- Brake Fluid Flush: Every 2 years.
- Transmission Fluid Service: Every 30,000 – 60,000 miles, depending on driving conditions.
- Differential Fluid Service: Every 30,000 – 60,000 miles, depending on driving conditions.
Remember that these are general guidelines, and your specific service needs may vary based on your driving habits, climate, and the overall condition of your vehicle.
