Default New DCT and iDrive Software coming out this weekend

My 2008 M3 is at the dealer for the DCT lag issue, engine idle fluctuation issue, and an iDrive issue (iDrive menu locking up). The dealer just called and said that they are downloading new software for all issues from BMW over the weekend and that they would reprogram the software on Tuesday. My service advisor said that BMW is releasing new software over the weekend to dealers.

If there's a SIB, can you please include that?

There is nothing else I can tell you guys.

BTW...the DCT lag issue is a well known issue. There was an SIB for that in June 2009.

Where exactly do you see the lag in the DCT? I notice it when going from reverse to 1st...it takes a couple seconds to engage so that I can pull away.

My '08 DCT would "think" for a second when starting off in 1st. There was about a 1 sec lag from R-->1. Also, if I slowed from 70 to 50 in 7th, then hit full throttle & click for 6th would get 3rd gear. They could never get it sorted out...

SI B 28 07 08
M Double-clutch Transmission with Drivelogic
June 2009
Technical Service
This Service Information bulletin supersedes SI B12 55 06 dated January 2009.
designates changes to this revision
SUBJECT
M3 with M DCT - Complaint of Delayed Throttle Response
MODEL
E90, E92, E93 with S65 and M DCT transmission up to 04/09 production
SITUATION
The customer may complain about delayed throttle response when reaccelerating after a series of downshifts
during heavy deceleration (hard braking). This condition is experienced when the transmission is in D or S
mode, with the Drivelogic program selected to three or less bars.
No acceleration delay is experienced when the vehicle is driven in the M manual mode.
INFORMATION
During a "rolling stop" situation, which is followed by heavy acceleration demand, the transmission goes
through the series of downshifts in order to match the appropriate gear with the high load signal.
The short time period necessary to perform the multiple downshifts may create the perception of "throttle
delay". In reality, it is a design characteristic and normal behavior for the M DCT transmission when operated
in D or Smode, rather then a malfunction or deficiency.
Due to the ongoing quality optimization process, the newest version of the M DCT software provides
additional improvements to the transmission drivability, resulting in further reduction of shifting time and
engine torque application.
To significantly improve the throttle response (or to reduce "throttle lag"), reprogram the vehicle with the
current ISTA/P version (target integration E089-09-03-510 or higher, introduced in ISTA/P 2.33.1).
In order to completely eliminate the delay sensation, as described above, the customer needs to operate the
M DCT in the manual mode (paddle or gear lever manual shifting).
Explain the M DCT's operating behavior, as described above, to the customer.
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle Limited Warranty or the Certified Pre-Owned Program.
Defect Code: 28 00 15 61 00
Labor Operation: Labor Allowance: Description:
61 00 801* 7 FRU Programming coding modules without CAS
61 00 811* 8 FRU Programming coding modules including CAS
*Main Work - use this labor operation number when this is the only repair being performed, or if this is
the main repair when performed along with other repairs at the same time. If this is not the main
repair, refer to KSD for the associated (+) labor operation code.

Oh, that SIB. That's not new, thats the big 09 update. There was one after that in May of this year, too I believe. I thought that there was an updated one after the May update.

Well I got the car back today and it shows on the invoice that they programmed the DCT with software 2.38.2

Is that a new version?
