Nearing 100k Miles! Any suggestions?

[Matticus91]

I'm just about to turn 90k miles and decided to do some parts orders during the sales this weekend and get my 100k mile maintenance out of the way early.

All suggestions on things to do are welcome!

So far I've ordered/Planned:

• Oil/Filter
• Spark Plugs
• Coils
• Front Rotors/Pads
• Brake Fluid

Things that have been done recently:

• Trans fluid
• Diff fluid
• Coolant
• PS Fluid
• Serp Belt
• Air Filter

You've got it covered from what I can see. I did the water pump and thermostat proactively at 100k, but some may find that overkill.

Those have already been done thankfully!

Oil filter housing gasket?

I'm in the same boat as you but can't think of anything else that I need to have replaced lol

[chris_flies]

Air Filters, both cabin and intake... I think you've got most of it covered. I'd also go through and make sure everything is nice and tight.

Though I don't think it's done as often as it used to be, 100k miles was often considered the useful service life of oxygen sensors. Now, sensors have probably gotten better, and the diagnostic tools we have available make it pretty easy to tell when one is failing, but if you really wanted to be diligent you could replace the pre-cat O2s proactively.

I'll never understand the 30,60, 100k checkups.
I'd lay odds you didn't do a checkup on yourself at 20, 30, 40 ...

us car folk are an odd bunch.

i am at 90k miles on my 1M.

some additional things to consider:
- Waterpump/Thermostat (60-80k miles)
- Fuel Injectors
- Battery (you can probably wait since you're a 2013, but every 6-7 years)
- Walnut blasting (do you have an N55? if so then it may not be as necessary as with the N54)

IF you're gonna do front rotors and pads you should also do the rear rotors and pads.

I am also considering doing a full replacement of hoses at 100k miles, preventatively; however i haven't decided this for sure. Has anyone else refreshed all of their hoses at 100k miles?

90k on a 1M ... you sir are on my hero list.

I'm at 80k miles and have replaced I believe 4 different hoses already. Only one was preventative.

90k That is awesome to see on a 1M.

I'm at 180k miles, and I've been replacing hoses as needed, it seems like none of them were touched before I got the car. So far, I've replaced the upper radiator hose and the little line that runs to the top of the expansion tank (plus the coolant pipe into the engine block and a coolant hose running across the front of the block, but those were part of an oil cooler retrofit). When the water pump inevitably fails, I'll replace all of those related hoses, too, as with the t-stat.

[iminhell1]

I'm 128k and haven't done any hoses. Bought it with 44k on the clock.

Actually the only 'maintance' I have done was more upgrades than it's broke fix it.
Brakes twice, first centric blanks/ stoptech sport pads, second stoptech slotted rotors/ sport pads. Flushed fluid both times.
Trans fluid and filter twice.
PS flush,,, fluid looked dirty because everything is black, fluid was just fine once I seen the new in there.
Ignition coils twice, Delphi are absolute junk voltage leaks past the stubby boots.
Sparkplugs 4 times ... yay n54 misfires.
Front wheel bearings, brake retaining bolts seized to old hubs, then stripped.
Rear diff, put in a mfactory and factory fluid. Didn't like the engagement, changed fluid. Didn't like engagement. Changed fluid, Redline super lightweight, like engagement.


VC was done before I bought it.
OFHG was done under warranty.
Front control arms done under warranty.
FRM done under warranty.
Waterpump done under warranty.


I do leak oil. Pan gasket only I think. Nothing hits the splash shield though so it's not a concern to me.

First thing done on the car lol

Engine air filter done recently, cabin air filters are BMS Washable

What 02 sensors? Lol I kid but I am catless with a DP fix installed

Speak for yourself! I make great use of my warranty AND my health insurance LOL.

Only thing on there I haven't done are the injectors. They're certainly on my list but since my warranty will replace them if needed it's hard to justify doing it myself.

128 is so much more reliable lol

[QUOTE= 128 is so much more reliable lol[/QUOTE]

So much more slower too....

You misread.
I have a FBO 135i N54 with 128,xxx miles on it. It's around that high 400whp mark and it's my year round DD.

Nice one!

But power to redline unlike the stock turbo N54/55 that falls on it's face after 5k lol.

OUCH Lol

I didn't think you'd need to worry about injectors being N55.

Check out the coolant hoses. I wouldn't go crazy replacing them all, but they should be pretty brittle by now. When I was refreshing the cooling system/new radiator, I pulled out the plastic piece that connects a hose to the head and it cracked - there's even an aftermarket metal version but I just opted for a new hose.

On my upper rad hose, the little barb that connects to the overflow broke off VERY easily. I'm over here in Florida so I think my plastics get more cooked than yours.

Wow yeah mine are totally fine and were actually also replaced after the accident

[Gangplank]

At that mileage I'd change the blinker fluid for sure.
