My Ride: '00 323i & 02 330xi
Here's a tip on the Axle's/boots in the front. NO U-Turns ESPECIALLY on cold days. Turning the wheel completely puts a tremendous amount of stress on the boots. Before you know it you will get the noise/vibrations when on the accelerator. I found out the hard way, since I didn't have to worry about this with my RWD 323I. If you keep from turning your wheel/sterring wheel to the max you will not have to worry about replaces those axles/boots on the AWD XI.

I purchased my 2002 330xi November 2009 w/110,000 miles on the clock mint condition. Rough roads and winter in the northeast cost me a lot in BS repairs. The car now has about 144,00 miles on it.

List of repairs not including Inspection I + II things. Coolant reservoir/expansion tank replacement, 2 rear strut mounts, 2 rear struts, 2 rear springs, 2 Front Axles, 2 Front Lower Control arm bushing, Valve Cover Gasket set, Valve cover (actual cover was cracked), Fan Clutch, DISA Flap (aka Adjuster Unit), 4 Oxygen Sensors, 6 Bosch Plugs, Electronic thermostat, 6 new tires (I bought 4 and less than a week later a pothole blew out entire right side, 2 days prior to the blowout a nj state trooper slammed on the brakes and smoked his tires in front of me causing me to do the same on the new tires, which caused a small flat spot in the tires!!!)

Again the suspension work was do to the extremely harsh winter and roads of the NY/NJ area. After I get this 330xi fixed (was rear ended on a hit and run), at the end of the summer I'm going to do engine mounts, and tranny mounts. My driver side lock actuator is shot, but I have two remote FOB's so the hell with fixing that. All in all its a awesome good performing car.

Replaced 3 half shafts since 2007 and have another leak in driver's side outer cv boot, why?
Drivers side tie rod boot torn, need to address

4. Front inner and outer CV's were cleaned and repacked with Mobil-1 grease. Stupid amount of vibration at around 50-60mph.
5. Two bent rims; two new tires. (Needless to say the previous owner did not avoid rough roads and the car was had for mighty cheap.)
6. Rear springs and shocks with Bilsteins. Oem were leaking bad and spring was cracked.
7. Left lower control arm with bushing.
8. All four brake pads/rotors.

In future:
1. clean re-lubricate/replace DME housing fan
2. AC condensor whines
3. Strange whoosh whoosh sound (consistenly timed) from front wheels when turning, left>right. Assuming it's the wheel bearings from the previous stress after previous owners lack of care but then again all e46's with these miles need major suspension care.
Now at 136,900 I've just finished doing:
4 new tires
Drive belt
A/C belt and recharge
VCG (second time)
Oil filter housing gasket
both front axles
left front control arm
both front wheel bearings
front and rear brakes (3rd time-warranty)
left rear bilstein shock (second time- warranty)
fuel filter
expansion tank
upper and lower radiator hoses
Emp stewart waterpump (second time- warranty as seals were weeping)
camshaft actuator line
right window regulator . . . .
Engine and tranny mounts are being done after a week of driving her post fixes.

I'm at 105k had it since 99k since then i've lowered it and replaced both front axles and the passenger rear, oil level sensor, front driveshaft, flux capacitor, front left wheel bearing, t-stat, and final stage resistor. All normal higher mileage e46xi stuff.

On my last one I sold it with 140k, got it at 108k. In that time I did the front right axle and oil changes that's all. she was a trooper.

You can now add engine mounts, transmission mounts, transmission drain plug, main positive battery cable fix, 2 front lower control arms (I should of did them when I did the bushings).

I just do annual maintenance on mine which consists of putting it in the air, seeing what needs to be replaced and what is on its way out. I typically replace everything so I can go another year with the car being the last thing on my mind.

Around 80k it got a new passenger side CV, DISA valve, water pump and expansion tank, spark plugs and fluids/filters
around 98k I put new brake pads on the rear, the rotors were just within spec for reuse.

Right now it has 116k on it and I did the following two months ago:
fluids and filters
replaced the thermostat and radiator hoses (hoses were preventative, thermostat had a small leak)
replaced the oil filter housing gasket
replaced the power steering return line (it was weeping at the bottom, probably could have just tightened the hose clamp but decided to replace the line and use crimp clamps instead)
replaced the PCV/oil separator assembly and all the hoses (preventative and it's easier to replace the hoses than reuse the old ones)
installed new accessory belts
installed a new transmission shift shaft seal (was barely weeping, was a good time to do when I was doing a fluid and filter on the trans)

A lot of the stuff I do on my car is preventative and I don't think most owners would even catch it until it becomes an actual problem.

The thing I love about these cars is they really don't seem to leave you stranded, stuff will break but you'll be able to get home. That has been my experience anyway.

I also have a set of Koni struts sitting in my garage I've been meaning to install, but the stock ones are doing fine :lol:

Things that can leave you stranded: battery, alternator, starter, fuel pump/filter.

Bought my 2003 325xi used with 96k from an old couple. The car now has about 130k.

Items replaced:

Things to replace:

This is my first BMW and I LOVE IT!! Only thing is that these cars are maintenance hogs & I'm starting to feel like I adopted a spoiled child instead of buying a car.

Between 38k miles and 88k miles:
LF control arm twice and bushings
Rear springs and shock mounts
Crankcase vent valve and hoses
Pressure, suction, and return power steering hoses
Both front axles replaced under bmw warranty, but both axles leaking again, need to take care of
Did water pump, tstat, and tank preventative when check engine came on for thermostat
Intake and exhaust cam sensors
Valve cover gaskets
Changed mech. tensioner to hydraulic tensioner and idler pulley due to horrible noise
All window regulators, drivers making noise again
Maintenance parts I consider normal:
Trans fluid/filter twice, front and rear diff oil change, transfer case oil change, coolant, brake flush twice, pads/rotors twice all around, air/cabin/oil filters every service reminder, tires at 40k
YES! BMWs require alot of maintaince/service to keep them driving like a BMW should

117k, the vapor barrier on the passenger side front door separated from the door allowing moisture to enter the cabin causing the passenger side floor board to become soaking wet. Fixed using a heat gun on the adhesive and reapplying the vapor barrier.

'01 with 114k:
Oil filter housing
Upper & lower throttle boots
Expansion tank
Bleeder screw (and hose it's attached to)
2 window regulators
Front LCA's, ball joints, & LCAB's (2x)
Both front axles (2x)
Oil level sensor
Valve cover gasket
Idler pulley
Both front shocks
Rear springs (1 broke almost in half)
Front and rear sway bar end links

I know there's more and as I list this, I get sad. My only consolation is that I'm my own mechanic.

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.
New shocks/struts/springs. Rear springs were cracked in half and fronts weren't far behind.
New DISA valve again
Reverse switch
Tail light recall
Rear sway bar end link snapped in half
Front driver sway bar end link worn out.

What's still wrong:
Front driver's window regulator
Left side steering wheel controls not working
Reverse switch doesn't work still

2002 330xi original owner

I have to tell you after 190K yes 190K I am still going strong sure I've done most of everything on the forum but my engine, transmission plus the clutch are all perfect. My mechanic recently did my valve cover gasket and he could not believe the condition of the engine. He was so impressed he took a picture to send to BMW, he works on my car on the side otherwise he is a master tech for a BMW dealership. Yes the windows regulators suck as well as some of the cooling system components like the thermostat and the water pump and yes you need to keep an eye on your CV boots.

Lets get real if those are my only complaints after a 190K well I got all of my monies back and much more. One more point I average 24.5 MPG on my 330xi. Good luck to all of you keep up with your maintenance use common sense and you'll be fine, you are driving an amazing car.
