DIY Oil Change, Air Filter, Cabin Filter, Power Steering Fluid

I just did my own

DIY Oil Change, Air Filter, Cabin Filter, Power Steering (ATF).


Things went pretty well.

Though I was not aware that you have to remove 2 splash guards to get to the drain plug.


Not hard at all.

I also had to replace Parking Light, which took me a while to figure out how to remove the light assembley, and then the bulb.
Its a screw, that is in a basket looking plastic thing.
I couldn't find the instructions in the Bentley BMW book, had to figure this out myself.
Maybe I missed the DIY guide here.

It scared me when the car symbol with a red light came on, but then I realized it meant a light was out.

Nice job! I am looking to do my first DIY oil change this weekend. I looked under the car and couldn't find a drain plug. I guess these cars have shields on them that have to be removed to get to it?!
The lights are kind of a pain. I just switched my OEM to clear tail and corner lights. The tails were totally overengineered and were a pain. Once I got going and figured it out was not so bad!
I also dorked around with pulling out the headlights and that was a bear to remove. I guess the cold weather package makes it alot harder than it could be. I lost a couple of the hard to get to screw in the car during the process! I had a hard time installing the bulbs since I put them on wrong. .

Anyway,I'd like to hit the brakes, Man trans fluid, and power steering also but am a little nervous.

Yes, 2 splash shields have to be removed to get to the drain plug.

I recommend a power drill to make getting those off faster.

I'd agree the headlights are a pain.

I though I had to get them off to do the parking light, but I didn't.

With the headlight washers I still wasnt able to figure out how to get the assembly off.

For the driver side headlight , you definitely have to take the Air Filter Housing off, as there is not much space to get to the connectors.

I lost 2 driver bits in the housing, and had to use a magnet and stick to get them out, as I didnt want to remove the splash shields again ...


My next fluid change will be the Differentials, and Manual transmission,
which doesnt look too hard either.

Yeah, maybe not using correct terminology.

How about battery powered drill/screwdriver with a phillips bit.

It just saves time, unless you like using elbow grease....

Yeah, really. They're 1/4 turn screws-or they should be.

All the screws only need about 3/4 turn to tighten. Power tool might be bulky under there. The plastic rivets up front are the hardest part.

A small lithium ion battery screwdriver is very light non bulky, and great for lazy people like me.

Also not so much torque that you are going to strip any threads.

I'm planning to do all fluid maintenance on my 2002 325 XI.

These are my fluid plans, what are yours?

Transmission Oil : Redline MTL (70W80)
Transfer Xase: Redline MTL (70W80)
Differentials (front/rear): Redline 75W-90
Power Steering: ATF DIII
Engine Oil: Mobil 1 5w-30

Supposedly OEM Tranny/Differential fluid is Pentosin 75w-80 (http://www.autohausaz.com)

What do you think?

I went out to the dealership to see if I could get the OEM fluids, they said I would have to buy them in a bulk, when asked how much, they were unable to answer me. The local dealership is currently pissing me off, as I ordered some parts, pre-paid, then came and pick it up, they were unable to locate them.

Could I use Dexron III for the Transfer Case and Manual Transmission too, instead of Dexron IV ?
That's what I used for the Power Steering.

I have a case of the the Dexron III, but if that wont work, I will buy something else.

Ok, maybe this is a separate thread,
but you have me curious on the oil extractors.

What brand is recommended, and how much are they ?
What is their capacity ?

Manual pumping or electric ?

I've never heard of them before.

Not sure for 2 oil changes a year, if it's worth it for me.

Thanks.

Thanks.
1.) Mityvac, about $70-$80
2.) Capacity varies, but you can get one that will easily hold the volume of oil in your car. You can also get one which both extracts and dispenses. Works well if you want to pump the oil or other fluids into another container. Can also get a brake bleeder attachment but I'm not sure how well that works.
3.) Manual Pump
4.) Cool, now you have.
5.) It's very worth it when it's -30F outside and you need to change your oil.

If the spec is gear oil, I wouldn't use an ATF in it's place.

Thanks Good point.

I assume the D4 recommendation was for the Automatic Transmission then.

FYI, Mobil 1 5w30 is NOT a recommended oil for your car. You need Mobil 1 0w40.

Yeah I know, my engine is going to blow up if I use 5W30,
and not the Euro Spec oil.



For a cheapie like me, I dont think it will make a diff. as I will be changing my oil every 6,000 miles or so, so wont need the 15,000 mile rating.

It probably makes a little diff to use 0w40, but even for Tribologist's, I am sure they wouldn't be able to tell.

I agree. However, a VERY good tech from Turner Motorsports that I know uses Castrol 5w-30 in all his customers' cars that he does on the side. I had it in my car for about 5k miles with no problems. He acknowledges it's not "BMW approved" oil, but emphatically claims it is 110% fine for 5k mile oil change intervals. It's a business, not a hobby for him though.

I had 15w-50 in my engine for a few months last summer to cut down on lifter-tick when it got very hot out. Again, no problems.
