N62 4.4i recall

[rayxi]

I just got my letter from BMW Canada a few days ago. Campaign number is different (ECR-B0001-10-002) but that may just be a BMW Canada vs BMW NA thing. The letter says it's applicable to "certain 2004 model year BMW X5" and is for a reflash of ECU and TCU software to fix communication errors.

My appointment is for next Wednesday. Depending on your existing version of the ECU and TCU software you may end up noticing differences. I'm not expecting any since I had the TCU updated recently. Not sure about the ECU.

On the recall, I doubt any performance changes will be seen.

I think my shifting is now worse. More so during warm up; it holds lower gears for longer and then abruptly upshifts - isn't smooth at all. When warm I notice gear changes (up and down) more than before.

I got my recall letter a month or so ago. My current position is "if it ain't broke, don't fix it." I had two updates done when it was under warranty and the performance and smoothness got much better after the second. As long as I continue to pass my state's emissions test, I don't see a reason to get the update. As 4MoJoe remarks, it has the potential to make performance and shifting worse.

I talked to my service manager last week. He said the recall is purely to enable the OBD port to properly talk to emissions testing equipment. There are absolutely no changes made to the engine or trans parameters. He told me that there was no rush to get it in for the flash until I get my Illinois emissions test notice.

I'm new to this forum, however I received the same recall letter. I was having a similar problem or symptoms described in another post here where the vehicle would shift abruptly from first to second when the vehicle was cold. It would go away in about a minute or two. It has 152,000 miles on it.
The dealer here in my town didn't know any real details about the recall other than they could do the programming. They did mention that it might take a few days for the system to "re-learn" my driving patterns.
The day after I started to notice some problems with what appeared to be the transfer case not slipping properly when cornering at low speeds. It got worse over the course of three or four days. I had it looked at by my mechanic and a drive train specialist and we believed it to be the transfer case being damaged internally, but with no way to tell unless you tear it down.
While I looked for parts and read up on this, mysteriously the symptoms went way in next few days. It got bad for one day, when I was with the mechanic, then it was gone. Drives just fine.
So I can't figure out if the programming made it worse and this "re-learning" actually worked. It's a bit confusing really.
