BMW vs. Audi Maintenance Costs, Everything You Should Know

If you’re the kind of driver who craves performance and refinement, chances are you've found yourself comparing BMW and Audi. These two German titans deliver a premium driving experience, but the real question is: Which one costs more to maintain?

Let’s break it down with real-world insights, from reliability to repair costs, so you know exactly what to expect before you buy or service your Audi or BMW.

Initial Maintenance Costs

Right out of the gate, both Audi and BMW carry premium price tags for scheduled services. In general:

• Audi maintenance costs slightly more up front
• BMW tends to make up for it later with more frequent wear-item services

Example: BMW 3 Series requires spark plug replacements every 4 years, while the Audi A4 can go up to 6 years between replacements.

Still, maintenance costs vary widely by model, so always check your specific vehicle’s maintenance schedule.

Which Brand Is More Reliable?

According to Consumer Reports, Audi holds a slight edge in overall reliability, potentially saving you from unexpected repair visits. But the winner really depends on the specific model:

• Audi A4 ranks better than the BMW 3 Series
• BMW X5 outperforms the Audi Q5 in reliability
• Newer Audi and BMW models are often on par, depending on the drivetrain and engine

Tip: Don’t rely on brand alone—research your exact model and year before you buy or plan for maintenance.

Recommended Maintenance Intervals

Both BMW and Audi recommend maintenance roughly every 10,000 to 15,000 miles, or once per year. However:

• Frequent short trips? City driving? You may need more frequent services.
• Skipping maintenance can lead to costly surprises for both brands.

Stick to your service schedule to avoid major repairs and premature component failures.
