Dedicated steps to swap AT on DCT
Part1 ( Hardware parts )
-12 51 7 581 112 wiring
-83 22 2 147 477 - DCT Oil 8l.
-51 16 9 141 518 - Cover center console
-61 31 9 133 067 and 61 31 9 213 647 - gear selector
-61 31 9 192 483 - park system for DCT
-DCT Transmission ( from E9X/E89 n54 n55 )
-DCT flywheel. Very important.
-If you have 2009.01+ car you number is - 21 20 7 590 853 ( 6 bolts 11 22 7 520 706 )
-If you have 2009.01 < car you number is - 21 20 7 593 469 ( 8 bolts 11 22 7 520 706 )
The different about flywheel only in bolts pattern.
-Rear differential 2.56
Part2 ( ECU parts ) ( If you have 2008/09> just skip this part )
MSD81 ECU (12 14 7 616 431 ) - if you have 2008/03 just skip this part
DSC Pump (34 51 6 789 308 or 34 51 6 863 356 ) - if you have 2008/09 just skip this part
DSC Sensor (34 52 6 780 334 or 34 52 6 850 375 ) - if you have 2008/09 just skip this part
DSC Sensor plug (http://www.realoem.com/bmw/showparts...95&hg=34&fg=20 ) - if you have 2008/09 just skip this part
I cant find this part #17 . But I buy used harness from car 2009+ and get this plug from it.
JBE2 or JBE3 ECU (61359286790 ) - if you have 2007/09 just skip this part
DCT shift paddles or m3 shift paddles
Part3 (harness to DCT Gear Selector )
You have to do the wiring harness to DCT gear selector switch.
Use this link to download scheme. ftp://share:share@ftp.corbina.net/DCT/
You have to make and integrate the harness that is marked in blue.
For this you must have parts
4 pin jack plug 61 13 8 380 696
2 pin jack plug 61 13 6 925 634
and also 6 pins 61 13 0 005 197 - 6
Also you need 10 pins pin jack plug. Unfortunately you can not buy it, you can do it yourself. You can buy a generic 10-pin connector on a spacing of 2.5 mm ( like this http://www.kosmodrom.com.ua/pic/HU-13.jpg )
Part4 ( Replacing JBE ECU ) ( if you have 2007/09 > skip this part )
You can find JBE ECU under the feet of the passenger seat.
First you must replace it on JBE2 or JBE3 ECU (61359286790 ).
After this you must integrate D-can bus line on new ECU. ( Old cars have K-line and new ECU will not work )
Change pin on OBD2 socket
7 to 14
and put the additional wire between OBD2 socket pin 6 and JBE ( blue connector ) pin 17
Part5 ( Replacing DSC ECU ) ( if you have 2008/09 > skip this part )
Replace DSC unit on new.
Replace DSC sensor on new. ( You can find DSC sensor under drive seat )
Replace DSC Sensor Plug. The DSC sensor must be connect to DSC unit follows
DSC UNIT > DSC Sensor
39 > 4
27 > 2
11 > 3
28 > 1
After this you must calibrate you DSC unit and sensors. ( use bmw ISTA to do this ),
you just need to pump the brakes.
Part4 ( Replacing MSD80 on MSD 81 ) ( if you have 2008/03 > just program it )
Replace you MSD80 on 81.
Very important! you cann't use used MSD81 unit. you should buy it new
Program it on Zub 7628524
Do not forget to transfer the value of the injectors in the new MSD81.
Part6 Programming and Coding
I use NCS Expert and Win KFP to program and code my car
Remove FA $205
Remove value that starts # and Add #0909
Add FA $2TC
Make FA write on CAS and NFRM
Code ECU: MSD81/CAS/Kombi/IHK/JBFE/NFRM/GWS
Program MSD81 on Zub 7628524
Program GS40 on Zub 7600042
Update you Kombi/NFRM/GWS
