"The Lurch" does any of the tranny updates fix it?

Well part of it is the torque converter. Getting on the freeway a couple months ago I got a really bad slipping between a gear change accompanied with a bad whining noise. I continued to hear that for a while and now it has gone away and is non existent. All those signs pointed my though towards the torque converter.

The lurch is a totally different issue and is transmission related. I am very frustrated cause I have driven a 2007 Range Rover. Bear with me here, I know is not the exact same transmission but it has one from the era of when BMW owned Land Rover and it is the smoothest ever and no lurch stopping.

I expressed my dissatisfaction with my SA and I am going back next week, so we will see what they come up with this time. I will keep everyone posted as I find out myself.

I have the same issue - a shudder when the car is brought to a stop. My X5 is a MY06 3.0d, and I had the transmission adaptations reset with the software update. The problem seemed to had gone for a while but it is there intermittently.
Noit happy with the outcome. I am wondering whether to write to BMW Australia and state the case for a new transmission given that the car has done only 60k km in the upcoming five years of ownership.

While I was having a bunch of other work done to my '06 4.4i, I had the trans software flashed to the latest revision (v17?) - while the lurch is not totally gone, it is _SO_ much better than it was before!

I believe the latest software version is 40.2.0.1 EGS HW INDEX 72.

X5- do you know when that last update was implemented? I only ask as I was part of this original thread and when I went to dealer (while still under original warranty) I was told that I had latest version.

Fast forward to last week when I was at dealer (first CPO visit) and was told that:

"there is an SI for programming the EGS Control Module for this complaint. To update software in EGS control unit for improved shifting. Programming for software update is $210.00 Programming EGS in and of itself is not covered under CPO"

If I am told while under full warranty that I'm up to date, and then told after (CPO) that I am not, I am going to be pissed. ...

I don't actually know when it was implemented, but I do know that it is current as of January 2011. Not sure about being covered under CPO. I believe strictly speaking programming isn't covered under CPO, but if there is a problem with a component and that requires reprogramming then they might be willing to cover it under CPO. Have the dealer hook it up to the computer and ask them what the current integration level is (ISTA/P), you should be able to get a printout of it.

Forget it mate you might as well piss in the wind! My was under warranty and I had a solicitor involved. Your out of warranty and your on your own!

i have also had the same issues, on the last service i bleated all over the service manager and since that service the problem has been minimised to the point that i am satisfied with it.

very very occasionally i get a VERY slight nudge as i come to a halt and it down shifts to 1st gear, typically this will be in slow bumper to bumper traffic when instead of slowing to a stop i slow and then slightly move ahead and then stop, it seems that the tranny instead of going straight to first decides to hang onto 2nd in the chance you will be speeding up and then when the vehicle does come to a stop it goes "oh sh#t" and selects 1st.

does that make sense???

ive quized my dealer but they are vague about what they have done, claiming a software upgrade!!

i feel that overall the tranny shift quality has improved, firmed up on what it was.

i might add i also had them change the tranny fluid, i wondered if maybe they had adjusted the line pressures, as the changes as stated are marginally firmer that they were.

Be keen to find out what they did. I had one of the engineers from BMW remotely access the ecu and said I had the latest software and the only way to fix was rebuild tranny. So keen if you can tell me more :-)

sorry i wish i could, when i first experienced the "lurch" i thought i had been rear ended.

i have 96000km on my X and am real happy with how it goes now.

next service i'll see if i can get any more info, i cant believe it was just changing the oil that did it
