Calling all high mileage xi owners (what has broken?)

Since my first post I now have the front passenger regulator to do. Things I forgot to add were the fan coupling.

I decided to pull out the previous owners info and put it here. It was purchased around 30-40k miles.

46,000 - front/rear brakes, Front stabilizer links, Coil springs
75,000 - Inspection II, driver belts, front left and right outer CV boots
78,000 - final stage resistor, p/s pump, battery, alternator

130,000 now
Right Front Axle
all four rotors
all four pads
all four sensors
brakes were my fault so cant blame the car there so only thing over 130,000 miles (i think i got lucky) is the axle good for me!

at 150000 replaced frt suspension pieces (all), alternator, radiator and hoses, rotors, pads, pulleys--nothing out of the ordinary yet--but am waiting for something to hit--will wind up doing all axles soon boots are cracked--drive the car pretty hard 90% of the time--most of this stuff was changed at 120-130K--xi is lowered, bilsteins, urethane bushings up front. I absolutely love this car--AWD handles great--goes thru the snow with ease--can turn the DSC off when I want to have some fun--wish it had another 60+ HP & torque

I'm at 88k and have done the following...
CV Axles - needed when i bought it
Starter - worst job EVER!
Alternator
Belts
Tensioners
Valve cover gasket
Front and rear pads and sensors
Front and rear rotors- front were unturnable so went drilled/slotted all around
Did the zip tie fix for front window regulator

Still love the car so the cost of repairs was well worth it.

car is at 173k....since i owned it driver window reg, expansion tank, battery, fcabs and ccv. However when my father in law owned it and i had my coupe i replaced full cooling system, power steering pump, all the spark plugs, a few coils and the remaining 3 window regs.

I can already sense the remaining suspension needs replacement along with front cv boots as well as another power steering pump and the alternator is beginning to whine

Recently bought my '01 330xi with 154k. Just broke 158k last weekend on a road trip. Half way there, the hood badge came flying off. Other than that, my crank case vent has gone bad, causing the car to burn oil, run rich, and throw a "Rich on bank 1 and bank 2" code. Also definitely needs front control arm bushings, like everyone else. And my alternator belt idler pulley occasionally makes noise. All part of the fun of owning a high-mileage car.

Only things out of the ordinary for me has been crankshaft position sensor, starter, and front wheel bearing.

I'd get those pulleys swapped out soonish.

Seller did 1 CV boot, I did other
I did cooling system(pump, thermostat, expansion tank, sensors)
Replaced belts
Replaced cabin air filter
Going to do spark plugs
Going to change trans and diff fluids

-did spark plugs
-did trans and diff fluid
-I ended up doing both CV joints and axles
-Replaced alternator voltage regulator, headlights pulse so doing it again
-replacing serp belt tensioner(mainly due to my wrenching, not faulty)
-replaced fuel filter
-replaced cracked intake boot

- DISA Valve
- Cabin Filter
- Air Filter
- Spark Plugs
- Front sway bar endlinks
- Tranny fluid
- Tires
- Rims (Not faulty, got a summer set)
- Oil/Filter change a handful of times

Still to do:
- Diff fluid
- TC fluid
- Shocks/Struts/Springs all around
- Fuel Filter
- Front driver window regulator

I've been lucky with the axles, CA bushing, and the usual stuff that goes wrong.

a lot of you guys are posting regular maintenance items. things dont go wrong. the bushing, Control arms, endlinks, tierods, brakes, etc.. are wear items. The only broken things for me were a secondary air pump control valve, t-stat, and a busted axle boot.

178,000 in my 03xi

had to replace..
-lower control arms and bushings
-both rear axle shaft diff seals
-still need to replace the clutch
-still need to replace high pressure p/s hose
but besides maintenance items those are about it and its still running strong.

At 106k (owned the car since 75k):
- Camshaft position sensor
- Coolant temp sensor
- Final stage resistor
- Both front axles
- Springs (passenger rear and driver front broke)
- Shocks and shock mounts

From what i gather from the forum my diff bushings are bad...and my passenger front window is slowly dying

122,500 miles; Purchased at 17,000 miles

Cooling system (105k miles):

• Expansion tank and cap
• Thermostat (replaced with an aluminum aftermarket)
• Hoses (those 2 connected to thermostat and the one connecting lower expansion to engine)
• Water temp sensor
• Thermostat
• Water pump

CCV (Crankcase ventilation and related pipes and hoses) - Done as PM - 110k miles

VANOS seals (Beisan) (110k miles) - done as PM - Valve Cover gasket and seals replaced

Front axles - Replaced right and left one time each; rebooted a time or two.

Front control arm bushings (CAB) ~75k miles

Front subframe-to-control arm ball joints - Replaced after mechanic split open the boots with a pickle fork. 115k miles

EBOX fan that ventilates the EBOX into passenger compartment - 110k miles - This fan starts to "chirp" lightly and sounds like a little bird is in your ventilation system. $100 fan. Simple install.

Auto Transmission service (ignoring the "Lifetime" fill sticker) - new filter and replace 6 quarts ATF(110k miles); drain and fill 5 quarts ATF at 120k miles (done twice in order to get a more complete fluid replacement) - Done as PM - Redline D4 ATF

Transfer case drain & fill - Done twice (110k miles & 122k miles) in order to get a more complete fluid replacement - PM

Spark plugs, fuel filter, tires, battery, brakes, etc - all replaced at normally expected times and "Inspection I & II" times.

I got halfway through page 2 and was about to post shocking comments about other guy's 02s and thier low mileage when i realized someone revived an old old thread!

Guess i'll toss in my issues while i'm at it. 02 i bought at 80K now has around 125K 4 yrs later. Previous owner ignored goddam EVERYTHING on the car. Just yesterday i finished replacing the RTABS and now she's all done.

Outside of normal tune up/maint shite...
rear shocks
front struts
control arms
fcabs
sway links
rear shocks
rtabs
front ball joints
thermostat
drive belts (cause of thermo)
rear window regulator
valve cover gasket
passenger front cv axel

Oh and the comment about Xi's part pricing i agree with. It's total bs our parts cost so freaking much. Especially when theres more of them to replace!

edit: shoot forgot about both rear springs and radiator hoses done as PM as well from thermo

50000 km rear spring broke
60000 km Valve cover gasket
60000 km both front CCV boots ripped and needed replacement.
70000 km ball joint in front control arm ripped.
70000 km all shocks lost pressure and needed replacement to Koni Yellows pairs with new Eibach ProKits.

105k...nothing out of the ordinary except the ABS is messin with me now but that's about it

I got the car at 100k and the last owner said it was bullet proof AND the only things he did was REGULAR MAINTAINANCE and parts that WEAR OUT...so I won't mention any of that. He worked at a dealership as a salesmen..seemed like a straight shooter

I trust this car to drive to the moon..OR Texas maybe hehe

I have 102340 miles on my 2003 330Xi, usual routine services and mantainence items and: secondary air pump and valve at 38K, Brakes_ rotors and pads twice, tires ( currently 2nd set), water pump and belts, ATF changed twice ( @ 50k & 100k). No issues currently, runs great!!
