- - Transmission software HELP (https://xoutpost.com/bmw-sav-forums/x5-e53-forum/37410-transmission-software-help.html)

Today I went back to dealer to complain of the jerk and lack of power between 30-40 mph. They said that it is known problem and want to take car back and drive with it more to analyze what is the next step. I'm now scheduled next week to drive with the main workshop tech to see how to proceed. My friend works for BMW manuf and said to keep on pushing with local dealer, it is a problem they need to fix. Let's see how it pays out.

04-06 is a different transmission, 6 speed with it's own set of issues.

The 02-03 is a 5-speed. The dealer more than likely re-set the transmission adaptive values even thought the EGS has the latest and greatest SW. Drive it for a couple of weeks so the transmission "re-learns" how you drive and see how it is then.

I'm still working with dealership to get this jerking problems soleved. Latest development is that dealer admitted their problems with the software update. In order to make needed adjustments done right they need to pay with software manually and then fix will kick in (read remove jerking problems). I'm now scheduled to go back next week and hopefully jerking will be history then.

Keep pushing the dealer (ask to see their service key technician to talk / drive w/ you) and they will help.

The only problem is that the X5 seems to lag when i push the accelerator down at once and there is a short pause followed by a jerk. Before it would Jerk and take off but now there seems to be a lag, and this is not only off the start, even on go the X will lag. The Gear changes are still smooth tho, its just the pedal response. So i taken into the dealer, and i have extended warranty, they tell me first everything is fine and i was like "no its not" so then they call back the next day and tell me they still not sure but i can change the transmission software and it "might" repair it. So i was "okay" and then they want me to pay $120 for the software. So they are not covering it by warranty and at the end they said there is no other choice, What Ya'll think i should do? i;m confused especially about repairing a software that might not even be the problem. ahh, the stealers always seem to be playing with my wallet one way or the other but do i really need this software for my problem? or has someone else had the same problem with thier tranny?

I had the same problem in my X. Dealer did the Tranny software and still had that jerk specially during hard accelaration. I tried resetting the adaptive shift by turning the key to position 2 for 10 seconds and turn off for 10 seconds and start car immidiately. It shifted smoother and the throttle response was much better. I also tried the adaptive shift reset done on most 7 series BMWs and this worked as well (turn key position in #2 all lights are on on the dash without starting the engine, floor the accelaration pedal and hold for 25 seconds, start the car). If these home based solutions don't make your X respond and shift better, take it to the dealer. it could be a tranny issue.
