I felt the bang again yesterday
 

I had the transmission software upgrade done, I don't know, almost a year ago. Prior to the upgrade, accelerating from a roll would result in a hard bang...almost like being rear ended. Well, it happened again yesterday. This one was worse than ever before, it literally snapped my neck. This is the first time it has happened since the upgrade. Anyone else have issues?

L I am taking mine back for a reflash. Also, the Dinan tranny software is close. I am going to get it. The word is the sw will fix a lot of these
problems. I will keep you up to date.

Okay, I almost fell for it....the thread title almost sounded NWS!!:rolleyes:

BTW, I thought you had a grey X5 and not a creme beige X5 or do you have creme beige interior? I just don't understand your sign on name as "Creamy X5 Go"?! :confused:

I took my X5 4.8 in Monday for this reason and went for a drive with the Tech. Of course it didn't happen again but I did confirm that he heard the strange low pitched whistle between gears. They had my car until Wednesday and said they could not duplicate either the BANG which as you said was like being rear ended or the whistle sound. I picked it up and on the way home could hear the whistle sound as before but no BANG yet.

Oh my god this misunderstanding again................:lmao:

L, if this is a one-time occurence, I suggest you just pretend it never happened. If it happens again, then bring it to the dealer. Honestly I think with BMWs, there's always going to be a few anamolies that won't be fixed.

Laura, I think you've mastered the art of reel'n them in with your thread titles. :rofl:

I had the software update a few months back. Things are slowly but steadily heading back to pre-update behavior. :confused: I'm guessing it's the adaptive part of the software taking over.

The update I had applied a month or so ago was supposed to be a VERY recent release from BMW. They mention "CIP version 23.02.02" on the service invoice. Check your service invoice to confirm they had applied the latest "fix" to your tranny. For myself, I have had no recurrence of the BANG problem yet, but I'm not holding my breath...

issues...
 

....oh yeah......oh, with my tranny??....no......sorry....;)...nice thread title...thoughyagotyasum....

Whew!

Most of us leches were breathless, opening up that post I suspect...

No clue here. Next car, L...get a freakin manual trans.
There are no "bangs", other than the rear tars breaking loose and
a little rear axle hop. ;)
BR,mD

She's gonna like the stick.
