Hope that fixes it.

bummer about the mirror. i'm curious to hear the outcome, because i've got an inop passenger mirror on the Touring, and both mirrors inop on the X3.

for the last two items - go pick up an E8-E12 torx socket set and an M12x1.5 tap - they'll be handy to have later on (especially the torx sockets). retapping the hub for the wheel bolt should be pretty easy - maybe a 5min job.

Ah, you see, I would...but as soon as I know my car's going into the shop, I think to myself "what other easy stuff can I slide in there?" Since my mechanic is pretty darn nice, I do not foresee him charging for the door at all. Out of curiosity, where else are torque sockets necessary on an E46?

If you have PA Soft, pull the codes. The GM module should have something logged for the mirrors. I know mine did when my driver's side mirror motor crapped out leaving my passenger side mirror in-op.

I did, see below:

Codes pulled via PA Soft on 01/07/18:













On the last one, notably all the car is stating is that the passenger mirror is not responding. I have noticed as well that while my seat position memory works for the seat position itself, the memory does not work for the mirror position i.e. if I push out the functioning driver's side mirror and press the memory button, the mirror does not return to the appropriate memory position. Furthermore, my passenger mirror has been working intermittently, and when it does, then the seat memory does affect the mirror position. Not sure what to make of that.

Any info on some of the other codes would be helpful as well

E-Torx is found on steering guibo, diff-to-driveshaft, diff-to-axles, front subframe (I think), etc.

Had no idea that's what they're called. You learn something new every day.

Weeeehehehehell...

Took the car the shop. First, so glad I let my mechanic do it because it ended up taking them more than an hour to re-tap the cross-threaded hub. Real pain the poo chute apparently despite being only the first 1mm of threading that was the issue. But it's on there, torques down the spec, and fits with the bevel of my wheel. Second, they got the door bolt down tight fo free. Third, my mechanic was not sure off the top of his head what would be the source of my passenger mirror issue. He didn't have a lot of time so I didn't press him but he said he would look into it when he has some time. So, for now I'll have to live with out reverse-tilt function like a plebe:



Fourth, I love shooting the breeze with my mechanic. He told me about a few of the cars that were in: one had a snapped rear suspension spring that the owner's wife had driven on for 3 years. Another was a E36 325is that had been through the business starting with an engine swap because the current engine "lost power once it warmed up" which was attributed to loss of compression from bent valves. A third was in for a suspension refresh (less exciting).

I have the Mirror tilt down turned off. Never found it useful and one less thing to break lol

I find it super useful. No car I have driven with that function has curbed right rear wheels.

Never!

Today I installed the Turner Motorsport Power Pulley Kit that I ordered when it was on sale back in December. Installation was relatively straight forward; I used both the instructions that were included with the kit itself, which weren't that helpful because Turner was trying to cover as many different BMW models in a single set of instructions so the specifics were scarce, and this DIY guide online:

http://www.bimmerfest.com/forums/sho...d.php?t=141297

Some installation notes:

• I ordered mine with the Bosch alternator pulley because, well, I have a Bosch alternator. Who woulda thunk?
• I tackled the alternator first because I figured if I couldn't get that off or ran into an issue, then it wasn't worth trying to go back to stock for the other parts.
• Getting the alternator off wasn't too tough. It definitely helped to bang on the bottom bolt to push the sleeve back, or else you'll be stuck yanking the alternator back and forth and possibly damaging the mounting points (more easily visualized here: https://www.youtube.com/watch?v=hrEehjM5tgQ&t=6m19s).
• I took the alternator pulley off with a few shots of my impact wrench. I added some loctite, but I have no idea how to torque the nut down to 44 ft-lbs because the whole thing spins freely. I tried sticking a screw driver through to lock up the vanes a la ZHPizza's redneck style, but it just bent the vane as I tried torquing the nut down. So I settled for thread locker and a few shots of my impact wrench.
• I had a similar problem tightening the power steering pulley to spec (16 ft-lbs). Even with the belt in place, it would spin. I think I got it to "tight enough" but it is a little disconcerting that I couldn't get the bolts tighter.
• The factory alternator pulley is heavy, much heavier than the larger Turner alternator pulley.
• UPDATE: After initial difficulty getting the power steering and alternator pulleys torqued down to spec, I was able to torque down everything using Hornung418, Sockethead, and ZHPizza's suggestions for good techniques (Link, essentially the posts of the next page). It boiled down to using a screw driver against the bolts to hold the power steering pulley in place as I torqued each bolt, and pinching the alternator pulley in place with my old belt and vice grips.

Impressions:
I'll save this section when I have more seat time, but I took it out for a spin and couldn't say I noticed too much of a difference. Paradoxically, the steering feels more boosted than before the installation, when it should be the other way around. Not sure if it's just in my head (most likely) or there's something to it that I'm missing.
