E-sys and R270 BMW Fxx 6WA Kombi Retrofit

Read lots of Kombi retrofit information on the web and found many people in need of it. Here, I will share the guide of how to replace the standard KOMBI in BMW F07/10/11 cars with a used extended 6WA Kombi.

 

Disclaimer:

YOU AREAT YOUR OWN RISK !

KOMBI’s with the 160D0WQ chip here!

 

What you need:

• a used 6WA KOMBI with a mileage LESS then your actual car mileage

(if you install a KOMBI with higher mileage, the CAS module in the car will likely update to this higher mileage, and there’s no possibility to revert !!! )

• R270 BDMProgrammer
• SOIC 8 Pin Testclip compatible with the R270
• WorkingE-Sys 3.22.5with actual PSDZData (49.4 is OK) for FLASHING
• Working E-Sys 3.18.4 for CODING (if you don’t have a token for3.22)

• BMW ENET cable(Ethernet to OBD) that works with E-Sys
• A good car charger/power supply (12V/70A is recommended, although I used one with 20A).

 

Step 1 – Erase the VIN in the used 6WA:

–> Open the KOMBI

1. Remove the 4 Torx-Screws from back cover

2. remove the "Warranty Void Label” (of course, KOMBI warrantywill be lost from now on)

3. carefully unclip the 5 securing clips (without breaking them),beginning with the 2 bottom ones

4. remove the front cover (paying attention to the KOMBI Buttonwhich will fall off (simply put it back later on)

5. carefully unclip the back cover noses (one on the top, one on eachside) an remove back cover

6. very carefully unclip the flat-wire on the right (Flip the connectorup by using a flat screwdriver, then slowly remove the wires).

DON’T DAMAGE THE CONNECTOR OR THE WIRES.

7. Separate the secondary board from the main board, simply bysqueezing the white securing tips and pulling the secondary boardupwards. Watch out not to stress the lower flat wires.

8. unfold the secondary board
9. search the 8 Pin "160D0WQ” Chip on the mainboard (it’s rathertiny)

the top one of the 2 SOIC 8 chips

 

–> Erase VIN on the 160D0WQ

1. Start theR270Software (supposing you did install it correctlywith all drivers before)

2. On the Main Screen, click on "MCU” and select "160D/35160”.Click "OK”

3. Connect the SOIC Tesclip to the 160D0WQ-Chip.

4. Click "Read” : the EEPROM should be read. If not, check thetestclip position and orientation.

5. Save the unmodified BIN and make a backup copy to a safe place
6. Now erase the VIN

(a) Replace (not insert !!!) byte 70 0F (1 pair) with "FF” (longVIN)

(b) Replace all bytes from 80 00 to 80 0F (the whole line) with"FF” (long VIN)

(c) Replace bytes 590 0E and 590 0F (2 pairs) with "FF” (shortVIN)

(d) Replace bytes 5A0 00 to 5A0 04 (5 pairs) with "FF” (shortVIN)

(e) Save the modified BIN (choose a new filename)

(f) on the main screen, click on "WRITE”. The modified BIN isnow written to the EEPROM, and the data will be verified.

(g) Read the EEPROM again and check the modified bytes tobe sure everything is ok.

7. Reassemble the KOMBI (be sure the flatwire is correctly fitted).

 

Step 2 – Bench-check the mileage

Before installing the KOMBI in the car, it’s a good idea to check themileage outside the car just to be sure the MILEAGE in the 6WA ISLOWER THAN THE ONE IN THE CAR.

1. Locate the large connector on the back of the KOMBI.

2. The pins are labeled with small numbers.

3. Connect a 12V Power Supply so that PINS 1&2 are connected to+12V, pins 7&8 to GND(-). Make sure the pins are well isolatedfrom the neighbour pins!

4. Turn on the Power Supply.

5. Press the KOMBI Button : the stored mileage is shown on theLCD.

 

Step 3 – Install the 6WA into the car

–> Removing old KOMBI

This is an easy job. Just search YOUTUBE for "BMW Fxx removecluster”. This is the easiest way to see how it’s done.

Remove the 2 attached connectors : one at the TOP (the HUD connector)and the large one on the back (on both, a tab has to be pressedbefore actually pulling the connectors).

 

–>Install the 6WA

This is just the reverse of the removal procedure.

 

Step 4 – Flash

This is the most critical part! Be careful that you follow all the stepscorrectly. Again, I will not be responsible for any faults thatcould occur to the car or anything else !!! Use the instructionsat your own risk!

1. Hook up your car charger. A suitable car charger is very important.

Any power loss or low-voltage that could occur duringflashing might corrupt your car software! Also, use a fast computer

(I used an i5 3,6GHz / 16GB Ram iMac which workedfine).

2. Connect E-Sys 3.22.5 to the car (when you used E-Sys 3.18 sofar, uninstall it, then install 3.22.5. Later on, you can uninstall3.22.5 again and reinstall 3.18.4)

3. Before you begin, in E-Sys, go to the Menu "Options” / "Settings…”and make sure "Update VCM after TAL execution” is CHECKED.

(This will write the new FA to the car after flashing. If you don’t want this, UNcheck "Update VCM after TAL execution” )

4. go to "COMFORT MODE” / "TAL-Calculating”
5. click Vehicle Order "Read”.
6. click Vehicle Order "Save” Choose "newFA” as filename.
7. click Vehicle Order "Edit”.
8. Expand the "FA” Folder, then "FZAuftrag”, then "TYPE”
9. If "Zeitkriterium” of your car is anything below "0311”, change"Zeitkriterium” to "0311” (since 6WA was available only fromMarch 2011 on”.

10. Click on "SALAPA-Element”
11. add "6WA” to the "SALAPA-Element List” and the PRESS

CTRL-ENTER (or click the icon in the list header).

12. click on the SAVE Icon (the Disk) in the Top-Toolbar.

13. click the "BACK” arrow in the Top-Toolbar (Select "YES” whenprompted to reload Vehicle Order) to get back to the "COMFORTMODE/TAL Calculating” screen.

14. Check if 0311 and 6WA were successfully changed in the FA-List.
15. Right-Click on "FA” and select "Activate FA”.
16. In the "SVT Actual” section, click on "Read SVT”.
17. In the "SVT Actual” section, click on "Save”. Choose "SVT_IST”as filename.

18. In the "KIS/SVT Target” section, click on "Load” and load thejust saved "SVT_IST” file.

19. In the "Calculation Strategy” (still in "KIS/SVT Target”) section,choose "Complete Flash”

20. In the "KIS/SVT Target” section, select "I-Step (ship.)” : choosean I-Level matching the one from the 6WA (if you don’t know it,choose an older I-Level)

21. In the "KIS/SVT Target” section, select the latest I-Level on"I-Step (target)”.

22. In the "KIS/SVT Target” section, click on "Calculate”
23. In the "KIS/SVT Target” section, click on "Save”. Choose "SVT_SOLL”as filename.

24. In the "TAL” Section, click on "Calculation”.
25. In the "TAL” Section, click on "Save”. Choose "newTAL” asfilename.

26. Go to "Expert Mode” / "TAL Processing” (pic.14)
27. Click on the "…” button near the TAL-Line and select your "newTAL”file.

28. Click on the "…” button near the SVT-Line and select your"SVT_SOLL” file.

29. Click on the "…” button near the FA-Line and select your "newFA”file.

30. Click on "Read VIN”
31. Now UNCHECK all the "ALL” checkboxes. (This is very important…not doing this will flash other ECU’s beside KOMBI aswell.) Now, no checkbox at all should be ticked,

32. Make checkboxes in the KOMBI-Line : "blFlash” / "swDeploy”/ "cdDeploy” / "ibaDeploy” (only those 4 and only the ones forKOMBI)

33. Click on "Check Software availability”
34. Now be sure again that E-Sys is well connected (e.g. that theconnection has not been lost) and that the car charger is working,since the next step will begin the FLASHING PROCEDURE.

35. Click on "Start”. Flashing should begin. During this, don’t beafraid of certain noises or strange behavior of the car that willoccur . The process will take about 13 Minutes. Just before theend, the fuel pump will run at high speed… don’t be afraid, thisis OK! Don’t touch your computer and the car during the flashprocess !!!.

 

Step 5 – Date & Time setting, KOMBI fully works

After the flash procedure, the KOMBI should reset and come backwith no errors.

Now set the DATE and the TIME in youri-Drive Menu (else the Service-Interval will not work).

You might now reinstall E-Sys 3.18.4 to code your preferences to the6WA (if you wish).

That’s it ! The KOMBI should now show your old mileage and shouldfully work.

 

Step 6 – Write FA to the car(optional)

The FA is automatically written to the car when"Update VCM after TAL execution” was ENABLED in step 3. If not,

you can still write the new FA (or, for whatever reason, write backyour original FA) following these steps:

1. in E-Sys, go to "Expert Mode” / "VCM”
2. Click on "…” in the "File”-Tab and load the FA you want towrite to the car.

3. In the FA-Editor, right-click on "FA” an choose "calculate FP”
4. Click on the "VCM Master”-Tab (still in Expert Mode/VCM)
5. Click on "Write FA FP”
