Replaced the valve stem seals in my 2005 X5 with an N62.
What a pain in the arse that job was but truck is now smoke free!

Reset DME (engine computer) adaptions as I put in new spark plugs (NGK BKR6EGP #7092) due to previous ones being oil fouled from the valve stem seals and causing misfires.

Transmission shifts when engine was cold were clunky even after fluid and filter replacement so I reset the adaptions today using the BMW Rheingold software with an eBay K+DCAN adapter (had to short terminals 7-8 for the 2 k-line buses) and now shifts like new; smooth and silky.

Replaced the transfer case oil awhile ago but never got around to resetting its adaptions due to group consensus saying I needed to use the ancient BMW DIS/GT1 service software but I dug around Rheingold today and found the ability to reset the VTG adaptions.

Truck feels like new now!

A/C is not working: RR Auxiliary Fan (expensive part!) but it is all good.
Scan reported sign(s) of heater valve component failure - For now I am surviving with AC set to the 3 blue dots. Warm air if it set to either 2 blue dots or 1 blue dot.

I just replaced my heater valve, I kept having my right side vents blow warm air, which is unacceptable in Arizona where it's 100º+ for several months of the year. It was a very easy DIY and I did it while half-asleep at midnight last night. Problem solved, now the AC blows cold from all vents.

Not so easy an R&R on an e36... had to do one of those recently. Stupid thing is stuck behind the intake manifold on the firewall.

Replaced my aux fan, start to finish inside of 2 hours. Feels great to use my AC in traffic again.

Just replace the Nav screen with a brand new sharp screen from ebay

I've had an intermittent miss for several weeks. No codes. Had done all the basic troubleshooting stuff but hard to find something when it isn't happening. Recently it started missing more frequently but still no codes. Used software to monitor engine but didn't see anything conclusive though with cutouts open it became clear it was only on one bank. I had already check for vacuum leak with propane and brake cleaner but found nothing. I had another MAF so swapped that out and it made no difference. Didn't seem like it was a plug issues so I decided rather than check them I would make a smoke test machine and check for vacuum leak again. It was easy to see the vacuum leak with smoke tester. One of those never should happen things. One of the valve cover bolts had backed off. I tightened the bolt and vacuum leak is gone.

It ran terrible at first, stalling and even went into engine failsafe a couple of times. Took about half an hour for engine to figure out leak was gone and make the adjustments. Held RPMs at 3000 twice for a couple minutes. Let it idle for ten minutes with air on. Let it idle for 10 minutes with air off. Revved it several times to different RPMs and let it free fall to idle. Runs fine now.

Put the finishing touches on my charge lead. Now that winter is biting hard I'm using the Webasto for 15 mins each morning (car not running) which is pretty hard on the battery. It copes with three or four days of this so I trickle-charge it overnight a couple of times a week, just to keep it in good condition.
