Hey guys,

First post here and with my 09 335ix over 80k miles now I wanted to make sure I get all the essentials done. Since I bought the car at 68K miles I've done following:

-Rear brake pads, rotors, sensor
-Low Pressure Fuel Sensor
-All new fuel injectors and plugs following misfire
-Valve Cover Assembly following oil leak
-Oil filter housing, rings, gaskets, seals, and coolant flush following coolant leak
-Oil Change ever 5-8K
-Air bag and blower motor recalls

All of that was in the first year of 2 owning the car and have had no issues since, but now I've gotten the brake fluid light and I'm wondering what else I should service as I do not know when the following was done last:

-Air / fuel filter
-Power Steering Fluid
-Tranny Fluid (Manual)
-Diff. Fluid
-Transfer Case Fluid
- Cabin Air Filter
-Tstat / Water Pump
-Fuel Pump
-Serp. Belt and pulleys
-Suspension stuff

I'd prefer to keep the car at least a couple more years, what should I absolutely get done asap vs. just get checked out?

Thanks for the help.

Man I would say if you are talking preventative at that millage:

You should really asses the status of:
- Serp. Belt and pulleys (Is due according to service manual)
I have heard of bad things when they start to go.

And I have heard you can check the part number to determine the age of:
-Tstat / Water Pump (You are living on the edge with this one)
Mine went in my 06 right after I got it in Jan with only 65k miles. I got lucky it was cold when it went out.
* I have been warned MANY times about the cooling system. The magnesium/aluminum blocks don't like the heat.

So I would put these two at the top:
- Serp. Belt and pulleys
- Tstat / Water Pump

You could knock these out pretty fast for cheap: (Easy wins)
- Diff. Fluid
- Cabin Air Filter
- Tranny Fluid (Manual) .... this one might be more involved than I realize.

The transfer case is a pain to get to, I need to get this done too. Fuel pump is a really good idea, but you have bigger fish on the list. You car will let you know how close the suspension is lol ..... but controls arms go out ALL the time at that mileage.
- Transfer Case Fluid
- Fuel Pump
- Suspension stuff
