E46 Touring Life

Bad news bears! Filled it up with fluids today and found a slow coolant leak coming from backside of the timing cover area. Which probably means the new orings on one of the new plastic coolant pipes I installed must not be seated properly.
Time to tear the intake back off to fix it.
-
Here is the plus-side though: More practice pulling the manifold while the engine is in the car will increase your confidence in doing any future maintenance items that require it (Hopefully there are none).
In my E30 ownership experience I had been into almost everything on that car to the point where swapping a diff or pulling the driveshaft was child’s play. Hope pulling the manifold becomes almost second nature like that for you.There is a very real mental-aspect about wrenching. When you don’t have the pressure to cobble together a repair to be able to drive to work on Monday, the challenge can become enjoyable.
-
Another plus side is more seat time in the Z Coupe.

Got the manifold off again and checked the two coolant pipes by pulling them off. First one was the pipe going to cylinder head. All looked good.
Took the pipe off going to the back of timing cover and found both oring deformed and pinched
No idea how this happened. I made sure the ports were extremely cleaned and lubed up the orings when I installed it. Oh well, at least it was an obvious issue. I popped two new orings on from my spare stash, luned them up with coolant and reinstalled them. I made sure to refill coolant to see if leak was fixed before reinstalling the manifold and all is good.

@B C came over this morning to attempt some coding as it's all foreign to me. We noticed that the shifter seemed to be rubbing on something when going into 5th and reverse is a no-go completely. The shifter carrier seems to be jammed up against the tunnel floor as well, which doesn't seem right.
I know the shift rod is on the correct side as it would hit the top of transmission when flipped the other way. I had to install the rear bushing carrier bracket due to my car missing this. I am curious if the way I installed it (check previous posts) pit the bushing too high which is lifting the whole carrier?
All I can find online is stuff for RWD e46s, nothing for the XI AWD shifter carrier as its different.
Any ideas? I will have to remove the exhaust and heatshield, possibly driveshaft again to get a good view on what's going on. Just figured I'd see what ya'll think in the meantime.

@i_love_cars any ideas? Reference to thread for his xi shifter install.

Auto to Manual coding in NCSExpert: All credit to 50sKid on youtube for the information. He had some trial and error in his video but I consolidated the correct required steps for future reference:
https://www.youtube.com/watch?v=FiBr1h9j0bU
NCS Expert
1) File>Load Profile>Expert mode (or Factory Coding, depends on which version of NCSExpert you have)
2) Go to “F1 VIN/ZCS FA”>”F3 ZCS/FA f.ECU” (reads vehicle order from module)
3) Select E46 Chassis
4) Select AKMB
5) Select “F2 Enter FA”, ignore incorrect VIN, click OK
6) Remove $205 (automatic transmission control module) from vehicle order by selecting it from the list and hitting the delete key.
7) Hit “OK” to exit
Click “F6 Back”9) Click “F4 Process ECU”
10) Select AKMB, click “OK”
11) Click “F2 Change Job”
12) Select “FA_Write” , click “OK”
13) Click “F3 Execute Job” watch for it to show “job ended” under AKMB
Now write the updated vehicle order to the ALSZ module:
14) Click “F1 Change ECU”
15) Select ALSZ
16) Verify that JOBNAME = FA_Write, if not, select “F2 Change Job” to “FA_WRITE”
17) Click “F3 Execute Job”
Exit NCS Expert
18) Open NCS Expert to check that $205 is gone from the vehicle order (steps 1-5)
19) Click “F6 Back”
20) Click “F3 Process Car”
21) Click “F1 Code Car” (these steps reset everything to default, this will not undo the $205 being removed from vehicle order)
22) If trans icon is flashing, unplug transmission control module.
23) Unplug blue connectors near DME (GM Module)
Run INPA
Clear error memory
Clear adaptations
You will know you are successful when the gear indicator on the instrument cluster is no longer illuminated (will not show a gear icon, will not show "P, R, N, D, or S", nothing) and the car can start with the clutch switch/clutch pressed

I was so stoked to hear it fire up and idle. Guess I must of done something right, lol. Next up is fix the shifter mishap and code the B30 files with SAI delete into the car. As always, thanks for the help @B C

Prepping for surgery. Cut out the raised trans tunnel section for shifter from a 330xi at wallys u-pull in Oshkosh this morning.
-
Interesting. So did all the xi's have the raised tunnel then?
This is my assumption based on everything I've read, seen and experienced through this process...
All preface lift e46 xit's, regardless of auto or manual, had the raised tunnel since bmw based all chassis' off of being manual even if they became auto's on the assembly line.
Then, for some unknown reason, the facelift xit's that were manual got the raised tunnel and auto's got the flat tunnel due to shifter assembly.
Again this is just my speculation with what I've seen and experienced.
-
Well I'll call that a success. Ended up cutting the dash console piece in one spot to make room. This spot will allow everything to bolt back together and never be seen. This extra space allowed me to cut back the carpet inside shifter area.
I made a template of the inside hump piece and traced it on the car to prep for cutting.
I then proceeded to cut it out carefully with a dremel, not to hit any of the wiring or catch something on fire.
Fits great and shifting feels exactly as it should now!
Now I just have to get some panelbond, seam sealer and rivets to attach it permanently and put all the interior back together.
-
Like it never happened...
Still have to seam seal and undercoat the underside, but I'm very happy with it. Shifts through all gears like it should.
I have to get a new black leather shift boot instead of the grey one I found at the u-pull. Also, once this whole project is wrapped up, this thing is getting a full interior detail for sure. Yikes!!!
-
Very nicely done! Im in for the detailing party
Deal!

330i front brakes installed

After more failed attempts at coding the B25 DME (kept having issues with connecting and finding the dme in the software), it was time to turn to plan b. Thanks to @m42b32 for having an extra MS43 DME and being able to flash it with everything I needed. Joe ended up putting the stock B30 tune, EWS delete and SAI delete on it and it worked like a charm.
After a couple startups to see how things were going, the engine started running extremely rough and wouldn't idle. @B C ended up stopping over with his computer. We checked fuel injectors, good. Checked coilpacks, good. Nothing was obvious from the outside, so we plugged the computer in to check error codes. After translating a few we narrowed it down to the DISA valve. Turns out the plug wasn't fully seated on the connector. Plugged it in and purred like a kitten. Sweet!
Torqued down axle nuts and crank bolt, bled the clutch a million different ways until it finally got all the air out, dropped it on the ZHP wheels and took it for a short "around the block" drive. All seems pretty good.
Time to throw the front end back on, hood, fill AC install airbox and start daily it.
