Hello you guys I have a f30 335i I am currently at 72k on my car and want to see what's recommended as far as maintenance

I am planning to keep the car for a couple more years and I want to have it properly maintained

I wanted to do a walnut shell blast very soon .

Anything else


Spark plugs I switched out at 50k
coil packs at 60k
and just regular oil changes and filters etc.



Anyone recommend other maintenance


Like trans fluid
Diff fluid
any other things that's is worth replacing or do a maintenance on

[sspade]

I recently did my diff. Mad simple.

I would recommend for piece of mind and low cost.

Im on the fence with transmission even though I really want it done.

Im a bit turned off that my dealer almost literally wont take my money to do it. They are very firm on the fact that its unnecessary and can cause more harm than good.

Hows your OFHG look?

Have you inspected other gaskets for leaks?

Another item that you may look into in the future is serpentine belt and pulley/tensioner.

Brake fluid and coolant.

I've done the valve cover gasket already like 5k miles ago

The ofhg look fine still
I should maybe just change it tho

I want to do the diff change too

And my tensioner is starting to make squeaky noise every morning tho

Coolant I haven't never replaced or done a flush I should do that too

Is the dealership aware that ZF recommends it to be changed between 50-75k? Buy the parts yourself from FCP euro and have any other shop do it.

Honestly... dont fuck with the OFHG if it looks fine. My opinion.

Yes they know. When I tell them that, of course they look at me like a retard whos trying to over maintain his car.

Kind of a weird situation to be honest.

They said "we will always do what the customer asks."

But... seems like they are nervous to do it and have me come back complaining of tranny trouble.

In my honest opinion....

Dropping the pan and re-filling spilled fluid is a great idea as long as you are at 80k or less. Maybe 100k max.

Just my opinion.

Cant speak for why some dealers are so hesitant.

@bavarianride

Sure is.

OFHG are identical as N55 in case we are wondering.

just note that N26 valve cover gasket and ignition coil are covered items

[sspade]

Both to 150k ?

I was not specifically aware.

I wonder how common an ignition coil is to get replaced (scot free).

I could definitely see the VCG as its somewhat visual but Id imagine the ignition coil being more lingering and unlikely to be a wham bam, thank you ma'am freebie. I feel like in order to qualify there would be a certain amount of dick around, diagnosis, potential labor costs, etc.

I'm planning to replace mine around 100k with my next set of plugs anyway but still good to know.

Do you have a DVOM? With the car cold, take off the reservoir/radiator cap and start the car, let it reach operating temp. Drop the positive lead into the reservoir, and put the black lead to ground. If your reading is .4v or greater, coolant needs to be changed (electrolysis is likely occurring). If it is below that, you’re good. Mine is at .02v right now.

Oh shit I didn't know that

Ima try that for sure



Idk about yaw but I like to have my car on point especially I drive a lot and honestly drive it very hard every now and then I have a heavy ass foot


and I don't have any plans on selling it soon so I'm being a little crazy on what I can do to keep the car as healthy ass possible

I’m the same way. I usually keep my cars past 200k, so a little extra money spent on maintenance in the short term hopefully translates into a lot less being spent on maintenance and repairs in the long term.

VCG(visual) and ignition coils(CEL) are the most common items that were replaced at dealers for emission warranty, those 2 are also frequent paid jobs@indy that people should not pay for.

An alternate method is to test the PH of the coolant, it starts alkaline, and when it approaches neutral pH=7, it may help to change.

BTW, BMW coolant 50/50 mix should greenish blue, when it pales to almost clear color, that's the cue of checking pH/voltage.

Right now the coolant on my reservoir looks blueish green

But I am going to do that check and see how it goes
