Best Tool to Change / Read & Write ISN Numbers in BMW

Looking for a tool would change / Read & Write ISN numbers in BMW? The best and the most expensive one is Microtronik AutoHex BMW advanced, then the Xhorse VVDI Pro, Yanhua Mini ACDP, CG AT200, CGDI FC200 etc.

  1. Expensive option : Microtronik AutoHex BMW

Review: Hexprog will cost you more in total, but it’s far better and has a lot of more functions. Been using Hexprog about a year now – best tool I have ever bought, well worth it.

Reading BMW ISN From CAS,DME, and DDE with Autohex II BMW Software:

Autohex II BMW Software is considered as one of the best BMW ISN Editors tool due to the user friendly software as well as the coverage of the DMEs and DDEs in BMW, Mini and Rolls Royce cars from 2003 up to date.

BMW ISN Reading and writing can be used from Autohex II software: CAS DME ISN Manager, This advanced function can do the following:

Read and Write ISN for CAS1, CAS2, CAS3 and CAS3+ (2 bytes ISN, 4 digits).

Read and Write SK (ISN 128 bits, 32 digits) for CAS1, CAS2, CAS3 and CAS3+.

Read all DME ISN for E series (2 bytes ISN, 4 digits).

Read all DME SK (ISN 128 bits, 32 digits) except MSS65 in E series, it supports SK writing to most of these DMEs.

Read most DDE ISN (2 bytes ISN, 4 digits) in E series (2003-2006).

Read and Write All DDE SK (ISN 128 bits, 32 digits) in E series (2006 and up).

Read ISN for EGS 6HP in E Series, and automatically matching with CAS.

Read and Write BMW ISN for most of BOSCH DMEs in F series.

Read and Write ISN in CAS:

Some CAS3+ part numbers require CAS Firmware before you can read/write BMW ISN. You will get a message from Autohex Software to notify you about using this function before you do any operation in CAS ISN.

To do BMW ISN Editing for CAS: from CAS DME ISN Manager, select option 1, you will get a window like below:

CAS ISN: is 4 bytes (8 digits) ISN, the last 4 digits represent the DME ISN, the DMEs that have only 4 digits ISN (like MSV70,ME9N45,DDE 5,…) are considered old, while the total 8 digits represent the 6HP EGS ISN.

CAS SK: is 16 byte (32 digits, 128 bits) ISN, this is the new ISN used in all new DMEs and DDEs (MSV80, MSD81, MSS60, MEV17_2, MEVD172Y,…), It also represent the ISN in 8HP EGS.

From this window you can save this info into file, as well as load saved ISN from a DME or CAS and write it into the current CAS.

Read and Write BMW ISN in DME and DDE:

As described before, there are two types of BMW DME/DDE ISN, short and long.

Autohex II supports following ISN:

DME / DDE E Series 4 digita:

D62M57A0,  D62M57B0,  D60PSA0,  D50M57A0,  D50M57E1,  D60M47A0,  D60M57A0,  MEV9N46L,  ME9N45,  ME9N62,  ME9E65_6,  N73_L0,  N73_R0,  ME9N62_2, MSV70, MS450DS0, N62_TUE, N62_TUE2.

DME /DDE E Series long ISN (SK):

MSV80,  MSD80,  MSD81,  MSD85,  MSD85Y,  MSS60,  MEVD176K,  ME17N45,  MED17_2,  MED17_2N,  MEV17_2,  MEV17N46,  MEVD174K, MEVD174KW,  MV1722,  MVD1722,  MEVD172,  MEVD1724,  MEVD1725,  MEVD172Y,  MEVD17KW,  D70N47A0,  D70N47B0,  D71N47A0,  D71N47B0,  D71N47C0,  D71N47D0,  D72N47A0,  D72N47B0,  D73N47A0,  D73N57A0,  D73N57B0,  D73N57C0,  D73N57D0.

DME /DDE F Series long ISN (SK):

MSD85, MSD87, MSV90, MEVD1723,

MEVD172Y,  MEVD172,  MEVD1724,  MEVD1725,  N63TU_L0,  N63TU_R0,  S63TU_L0,  S63TU_R0, EDC17C41, EDC17C09, EDC17CP45,

EDC17CP49, EDC17C50, EDC17C56, EDC17C76

DME ISN (SK) is read/write in all above DMEs/DDEs.

MDG1 On Bench: DME_83T1, DME_841, DME_841H, DME_861, DME_88T0, DDE803

And DME ISN (SK) is read/write in most MDG1 Ecus in BMW F series.

DME G Series long ISN (SK):

DME_840, DME_840H, DME_84T0, DME_860, DME_86T0, DME_88T0,

DME ISN (SK) is read/write in most MDG1 Ecus in BMW G series.

Changing ISN in BMW and Mini DDE/DME

In BMW E series and Mini cooper you will see a window looks like above, A notable ISN Mode can be seen (ISN Mode: Read / Write), while the read/write ISN is supported in all DMEs in F series.

This means that Autohex II is almost able to change the DME ISN, this is a very important feature because we will not need to touch the CAS ISN.

The best practice when working on DME/DDE ISN is to avoid (if applicable) changing BMW ISN in CAS because:

-You may have to do CAS Firmware before you can write ISN into CAS.

-Some CAS part numbers (938XXXX, 939XXXX) don’t accept long ISN editing, only ISN reading is allowed.

-If the car is equipped with an EGS 8HP which shares the same ISN (SK) in DME and CAS, it will be locked when you modify CAS ISN to be matched with DME/DDE (as a result EGS 8HP ISN differs from CAS ISN).

If you see the status of ISN Mode is Read/Write you can match ISN as follow:

-Read ISN from old DME/DDE, and save it as a file ( see above picture).

-Replace the defected DME/DDE with the donor.

-Write the saved ISN from original DME/DDE into this Ecu.

-Go to Indiv programming and program the Ecu (optional, or you have to at least do coding).

-You are done! Start the car.

In the case of DME is read only (MSD81, MSD85,…), there is a solution to modify BMW ISN in these modules via ISN Tricore boot mode using Autohex II tool.

  1. Xhorse VVDI Prog can Read and Write ISN in BMW

VVDI2 won’t change isn in bmw. I would go for Xhorse vvdi prog instead.

Xhorse VVDI Pro is able to read some ISN code (N20 N55 B38 B48 etc)

VVDI Pro can read the following ISN:

EDC17C56(N57) (bosch ecu adapter)

EDC17C56(N57) (bosch ecu adapter)

EDC17C50_Fxx(B37/B47/N47K(bosch ecu adapter)

EDC17C76 [N47/N57] (bosch ecu adapter)

EDC17CP49(B47/N57) (bosch ecu adapter)

MEVD17_2_3(B38) (bosch ecu adapter)

MEVD17_2_K(B38) (bosch ecu adapter)

MEVD17.2.4 Exx(N20)(bosch ecu adapter) 三

MEVD17.2.4_Fxx(N20) (bosch ecu adapter)

MEVD17.2.5 (N38) (bosch ecu adapter)

MEVD17.2.6(N55) (bosch ecu adapter)

MEVD17.2.8(N63/S63K bosch ecu adapter >

MEVD17.2.9_Exx(N20) (bosch ecu adapter)

MEVD17.29_Fxx(N20) (bosch ecu adapter)

MEVD17.2.H (N63/S63) (bosch ecu adapter)

Attach Xhorse VVDI Prog Bosh ECU Adapter (buy separately):

Used for: Read BMW ECU N20 N55 B38 B48 ISN without Opening

It works with network connection.

Support reading the data and the software will automatically display the ISN.

It’s sure this cable will work for other ecus in future.

With this cable, the ECU shell won’t be damaged.

Which one to choose, it depends on your budget and how deep you use them.

-Microtronik AutoHex BMW advanced: most expensive

-Xhorse VVDI Pro is for $425

-Yanhua Mini ACDP ($219 + $199): key programmer + ISN reading and writing

-CG AT200 ($459 + $229): ISN reading and ECU programmer, better purchase CGDI FC200 (the upgraded version of CG AT200 and with full authorization, and charge $638 in total)

Hope it helps!
