Follow these steps carefully
Start the M54 and let it idle for two to three minutes so the oil warms and drains out completely, then park on level ground. Set the parking brake and chock the rear wheels.
Raise the front of the Z4 onto jack stands and remove the underbody splash shield with its screws and plastic fasteners. The E85's low nose means you need the clearance to reach the drain plug comfortably.
Slide a drain pan under the oil pan, remove the drain plug, and let the M54 empty for 10 to 15 minutes. Put a new crush washer on the plug and thread it back in by hand before tightening.
From above, unscrew the black plastic oil filter housing cap on the M54 with a 36mm socket and lift out the old cartridge. Remove the spent O-rings from the cap and wipe the sealing surfaces clean.
Lightly coat the new O-rings with fresh oil, press them into the cap grooves, and install the new cartridge element. Start the cap by hand, then snug it with the 36mm socket — the plastic cracks if you heave on it.
Tighten the drain plug with its new washer and reinstall the splash shield with every original fastener. Check that nothing is left dangling before lowering the car.
Add roughly 6.5 liters (6.9 quarts) of BMW LL-01 5W-30 through the filler, pouring the last half liter slowly. Unlike newer BMWs, the M54 has a real dipstick — use it.
Start the engine and check underneath for leaks at the plug and filter housing. Pull the dipstick, wipe, reinsert, and read the level; adjust to the full mark and you are done — no electronic reset needed on this generation.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
