William's 330Ci ZHP Maintenance and Project Thread

[Galapolis]

Sounds like I should swap to BMW fluid then, so long as FCP stocks it. I didn't even put that much mileage on mine (maybe 20k km?) and it was dark when I drained it.

Sphericals are definitely the RTA to go with, but I found I was still spinning up the inside rear wheel on track. They're for sure better than OE or poly, but I think I just had too high of expectations given the reviews on this forum

Yep every single transmission fluid change I watched always contained dark fluid and a lot of shavings. At first I was confused, but then I just felt dumb for replacing mine.

Great discussion regarding maintenance going on here

Looks like everything was covered but I'll chime in and say I've been using the Ravenol in my transmission too after going down the rabbit hole on m3forum. Feels good2me.

Thank you kindly everyone! I'm updating the list here for my own reference.
Green = parts already purchased
Maintenance
Fluids

• Brake fluid: Flush every two years (previously every one year). Continue to use 1L ATE SL6-1.
• Transmission fluid: I've passed the 30k mile mark and should probably change it for cheap maintenance. Currently Redline MTL, but will try Ravenol 75W-80 stuff per this thread.
• Differential fluid: At 30k miles, should flush sometime soon. Continue to use Redline 75W90.
• Power steering fluid: Overdue by a few thousand miles (30k interval) and about one year overdue for flush (five year interval). Continue to use ATF. See below regarding power steering lines.*

Mechanical items

• Power steering lines: Leak noted previously by my mechanic. Relatively sure it's the feed line (32416774215[?]), but may also be the return hose (32416796390) or suction hose (32416750155). Should also just assess if other lines/components need to be replaced.*
• Replace idler (11287841228) and tensioner pulleys (11281748131): At least one is dying already even though they were replaced 35k miles ago.
• Rebuild DISA: Use the German Auto Solutions rebuild kit.
• Replace leaking oil filter housing gasket (OFHG, 11421719855): Will purchase recommended BavAuto Viton version from ECS here, since BavAuto was absorbed by ECS.
• Replace soft fuel lines to/from fuel filter
• Replace differential bushings: One of them (unclear which) was found to be cracked by BMW dealership during complementary inspection. Will purchase OEM rubber parts (front: 33176770788, rear: 33176751808).
• Install upper (13541438761) and lower intake boots (13541438759): Perform when installing ZHPizza's larger throttle body**
• Clean the ICV while replacing intake boots above
• Replace AC blower: Although squeaking/fluttering sound has improved, will at some point need to replace the AC blower motor
• Replace driveshaft guibo/flexdisc (26117511454) and the center support bearing (26127501257). DIY guide here.

Exterior

• Replace windshield cowl (51718232894): Cracked and weathered.
• Repair cracked/dying rear window gaskets using this guide
• Replace or renew fading side markers

Miscellaneous

• Replace spare tire: I believe mine is original and should be replaced (I think it is T125/80R17)
• Get alignment following Bimmerworld spherical RTAB installation (see below)***

Modifications
Suspension

• Install used M3 27mm front sway bar (31352229755) and install correct bushings (31352229756).
• Install front sway bar end links (31356780847)
• Install Bimmerworld Spherical RTABs.***
• Install 330Cic or Xi rear sway bar (33556751267) w/ correct bushings (33551096669)

Engine/drivetrain:

• Install ZHPizza's larger throttle body.**. Details here. Additional associated parts
• Install M3 fuel baffle (16112229656)
• Install M3 motor mounts (11812283798 [2x])
• Purchase/install LSD of some sort with 3.23 or 3.38 ratio
• Purchase/install the M56 valve cover per this thread or purchase German Auto Solutions CCV Replacement Kit
• Fabricate/install custom brake duct air scoop: Using this guide

Electronics

• Reset Xtrons PB7646BAP to factory settings to see if that'll improve speed. Otherwise consider selling and getting an Avin Avant 4.
• Recode the car as a convertible to have one touch up/down windows: Using this guide. Would also require new center console trim and window switch (61316902183)
• Install M3 gauge cluster if someone can figure out coding the shift lights for a manual, non-M car.
• Install Bavsound Stage 1 speaker kit

Interior

• Repaint the Black Cube Trim to Silver Cube trim: Using this "guide" and Precision Grey paint from Advance Auto.

He said he always wanted to do it lol

I was going to say it didn't work for me, but all I did was hook up a vert window switch, change the coding in pasoft, and hope all the wiring was there for it to work. It was not so I abandoned it. Not worth any more effort than that to me.
