Typically every 60,000 miles (refer to manual for specific plug type and gap).

Coolant Flush:

Every 2-4 years or as per CBS.

Brake Fluid Flush:

Every 2 years regardless of mileage.

Power Steering Fluid:

Pentosin CHF 11S

Rod Bearings:

Main bearing shells (rod bearings) are a well-documented wear item on the S54 engine. Early failure can occur, especially with hard use and inadequate oil changes. Prevention involves using correct oil and proactive replacement.

Subframe Mounts:

Cracking of the rear subframe mounting points is a common structural issue due to the stresses placed on the chassis. Reinforcement kits are available.

Vanos:

VANOS system issues can arise, including solenoid failure, rattling noise from the VANOS hub, or oil leaks from the seals. The VANOS oil pump disc can also wear.

Throttle Actuators:

Electric throttle actuators can fail, leading to driveability issues. The cable throttle bodies are known for needing adjustment and synchronization.

Ccm Check Engine Light:

Carbon Canister Module (CCM) issues can trigger check engine lights. Diagnosis involves checking the CCM and its related hoses.
