BMW E46 3-Series DIY: Oil Change
This DIY article will help you successfully change the oil and oil filter in the E46 3-Series. This was done on a 325xi so there might be a few variations between the different models, but all should be closely related.
BMW recommends 15,000 miles for oil changes but i feel that is way more than it should be. I personally change the oil every 7,500 miles in the BMW
I know people have preferred oil types / weights / change intervals. This article is not to debate on these items, but to show the procedure to change your oil.
Ramps / Jack Stands
OEM Oil Filter Kit: 11 42 7 833 769
Synthetic Oil- 5w30 (Amount depends on your configuration- check your owners manual)
First thing we want to do is to get the car up in the air. I prefer race ramps, but you can get the car on jack stands using a jack. If going this route use the appropriate jack points on the car highlighted in the owners manual.
Pop the hood and crack the oil fill cap. This will make for a smooth drain once you remove the drain plug
With the car in the air you can grab your philips screw driver and go under the car. We need to remove the belly pan and the trans pan to access the oil drain plug. There are 7 screws holding the belly pan in place. I have highlighted their locations below
The design on this pan is great because the screw stay locked in the belly pan when loose so you can't misplace them. Once these 7 are loose you can remove the pan from out under the car.
Next move farther back and locate the three screw holding the trans cover on. Repeat the process and remove
With cover cover out of the way we can locate the drain plug. It is located on the passenger side. A picture of it can be found below
Position your oil drain pan beneath this bolt and grab your 17mm socket. Loosen it and remove it slowly so you don't drop the bolt in the oil pan.
Let all of the oil drain out of the pain while you work your way back up top
Time to remove the old oil filter. Grab your 1/4 ratchet and your huge 35mm socket.
The oil filter housing is located just to the left of the power steering reservoir. Remove the cap
Before you remove the oil filter make sure you put down a paper towel or rag as it will drip. Below is a shot of my old filter still attached to the housing
Grab your right angle pick and remove the old o-ring fitted into the oil filter cap as shown below
Grab the oil filter top and the end of the oil filter. Easily pull the oil filter out of the housing
Grab your new filter and o-ring from the box and install on the oil filter cap. The filter will just snap into place. I recommend lubricating the new oil-ring with a little bit of oil
Re-install the oil filter. Use the recommended torque specifications as written below
Torque Specifications: 25Nm (18 ft-lbs)
Locate your new crush washer from your oil change get and replace the oil one located on your drain plug bolt
Crawl back under the car and make sure all of the old oil has drained out of the pan. When ready you can install the drain plug bolt and tighten it down to the torque specs below
Torque Specifications: 25Nm (18 ft-lbs)
Reinstall your undercarriage panels
Grab you oil and fill to your recommended specifications. When complete, get the car down off the ramps or stands and start the car. Run engine check and check the level of the oil. Add if necessary
Oil Service Indicator Reset
1999 & 2000 E46: You need a service internal reset tool. You can also do it manually by following the link below
Manual Service Indicator Reset
Post 2000 E46: On Board Computer
1. Hold the odometer reset button and while turning Ignition to Position 1. Hold button until it displays "OIL SERVICE" or "INSPECTION" with RESET
2. Release button and press it gain until "RESET" or "RE" flashes.
3. Press the button again
That is pretty much it. You are all set for a couple more thousand miles before your next oil change
Hope this article has helped and motivated you guys to continue doing your own maintenance. Any questions please feel free to ask.
