BMW 120d E87 · 163 PS (2004–2007)
The 163 PS 120d is the most powerful diesel in the launch range. Its torque and specifications warrant a separate guide, without assuming different service intervals merely because it has more power.

Documented oil quantity
BMW’s June 2004 specification table lists 5.5 l for the 120d. Check the level after servicing; this figure does not justify exceeding the vehicle’s maximum mark.

Oil and diesel particulate filter
With DPF: the 2005 bulletin requires BMW Longlife-04 approval. Confirm DPF fitment; viscosity alone is insufficient.

Maintenance and records
Front and rear brake pads
Wear monitored separately by axle
CBS calculates separate due distances. Inspect brake condition before ordering replacement parts.
Source [9]Cabin microfilter
CBS tracking before March 2007
24 months
The pre-facelift system calculates this separately. Do not automatically apply the later oil-service grouping. The bulletin sets a 24-month maximum.
Source [10]Engine air filter
Every 3 engine oil services
Count completed oil services. Shorten the interval in dusty conditions.
Source [6]Brake fluid
Fixed interval — before March 2007
24 months
A calendar interval, including low-mileage cars. Keep the date of the last service.

Whichever comes first
60 000 km
48 months
Separate from an oil service. Use the date and distance recorded in the vehicle’s service history.
Source [5]Diesel fuel filter
Every 3 engine oil services
Replace the main fuel filter at this service. The bulletin allows a shorter interval for poor diesel quality.
Source [6]Questions about this version
Must the diesel fuel filter be changed at exactly 90,000 km?
The cited schedule counts every third oil service, whose timing varies with CBS. It is not a fixed mileage; diesel quality may require a shorter interval.
