Cabin filter details
Checked catalogs did not specify the filter access location. For most BMW ActiveHybrid 7L vehicles, the cabin air filter is typically located under the passenger-side dashboard or behind the glove box (varies by model). Confirm the exact procedure in your owner's manual before starting service.
Most cabin air filter manufacturers recommend replacing every 12,000–15,000 miles or once a year under normal driving conditions. High-dust or high-pollution environments may require more frequent changes. Confirm the exact interval in your owner's manual — this is general industry guidance, not a vehicle-specific specification.

Fitment scope and limits
Cabin air filter fitment is tracked at the year, make, and model level because the cabin filter sits in the HVAC system rather than the engine intake path.
The checked catalogs did not provide source-backed cabin filter location or replacement interval for this exact record, so this page does not publish those fields.
