2.1. Noun explanation
BMW: Bayerische Motoren Werke
EWS: Immobox used in earlier BMW cars
CAS: Car Access System(40 unit), mainly include CAS1(0K50E), CAS2(2K79X),
CAS3(0L01Y), CAS3+(0L15Y, 0M23S), CAS4(1L15Y, 5M48H, 1N35H), this
document will only use CAS1, 2, 3, 3+, 4, 4+ to express, don’t write detail mask. If
document have detail mask indicates the special explain to this type
FEM/BDC: Immobox used in some new BMW models after 2014(F-Series)
OBDII method: Connect BMW TOOL to car with OBDII interface
CAS PLUG: It is not a standard device, need buy for extra. Communication with
CAS through CANBUS 100Kbps.
CAS3+ encrypt version: Sometimes we call CAS3++. When the car (not encrypt
version) start, CAS will verify key, ECU will verify CAS. But for CAS3++ type, ECU will
verify key in addition. So add key for this type need working key or ISN support. For
the above reason, the introduction for CAS3+ is also applicable for CAS3+ encrypt
version. Expect write no applicable for CAS3+ encrypt version
ISTAP Version: Strictly, ISTAP belong to CAS3+ encrypt version, the only different is
that we cannot read CAS immodata by OBDII for ISTAP version.So the introduction
for CAS3 encrypt version also applicable for ISTAP version, expect write not
applicable for ISTAP. Fortunately, we can OBDII read ISTAP CAS immodata by
update CAS flash. VVDI2 –BMW update ISTAP version flash only need 10
minutes.
ISN: Identification Serial Number, this value use to verify ECU with key. 16 bytes
Known CAS3+ encrypt version(not ISTAP) SN: 9226238, 9227053, 9237046,
9237047
Known ISTAP version SN: 9262360, 9262361, 9278745, 9278746, 9287534,
9287535, 9267608, 9267609
Lost all key: The car lost all working key, there is big different from add key with
working key. Attention: before OBDII communication, you need open dangerous light,
press on the brakes for several times to active OBD communication

Auto Detect: Detect communication protocol automatically, support KWP-E6X…,
CAN bus 100Kbps, and CAN bus 500Kbps. Other functions need choose manually
OBDII KWP –E6X, E7X, E9X, E81, E82, E87, E89: Usually used in old cars with
CAS1, CAS2 and some CAS3
KWP –CAN bus 100Kbps: This type will be use when VVDI2 connect to CAS with
CAS PLUG or without gateway
KWP –CAN bus 500Kbps: This type will be use when connect to car with CAS3 or
CAS3+
BMW EWS KLine: When connect EWS with CAS PLUG, choose this type
BMW F-Series: This type can connect to CAS4 in BWM F-Series
(PICTURE 5.1)
Connect: Connect to CAS system. Attention: EWS don’t support this (see special
Attention 1). After connect to CAS, there will display detail information in CAS
identification. Auto Detect only support connect operate, you must choose a specific
type before you do other operations.
CAS identification:
CAS ID: CAS identification number
CAS type: CAS type is very important, the type shown here is detected by

BMW TOOL User Manual
Ver: 2.0
11
VVDI2-BMW, if the type detect incorrect here, add new key may not work.
Usually have the following types: CAS1, CAS2, CAS3/CAS3+, CAS3++,
CAS3++ (ISTAP), CAS4 etc.
CAS3/CAS3+: This means CAS should be CAS3 (0L01Y) or
CAS3+(0L15Y)(not encrypt version)
CAS3++: This means detected CAS3+ encrypt version
CAS3++ (ISTAP): Means ISTAP version
VIN: Vehicle identification number
Prod. Date: CAS production date
HW: CAS hardware version
FSV: Function software version in CAS
OSV: Operation software version in CAS
Read EEPROM: Support Read CAS1/CAS2/CAS3/CAS3+ (ISTAP version not
support) EEPROM. For CAS1/CAS2/CAS3 type require CAS PLUG; CAS3+ can use
OBDII or CAS PLUG. Attention: the read EEPROM for CAS3+ is not the whole
EEPROM dump, you can’t write it to CAS with BDM programmer, it can use to
prepare dealer key with File Make Key
Write EEPROM: Support write CAS1/CAS2/CAS3 EEPROM dump, requires CAS
PLUG
Save to File / Load From File: Save the reading data / load EEPROM dump to buffer
Read KM: Read KM stored in CAS system, support CAS1/CAS2/CAS3/CAS3+
(ISTAP version not support). CAS1, CAS2, CAS3 require CAS PLUG; CAS3+ can
access by OBDII and CAS PLUG
Write KM: Write new KM to CAS, support CAS1/CAS2/CAS3/CAS3+ (ISTAP version
not support). CAS1, CAS2, CAS3 require CAS PLUG; CAS3+ can access by OBDII
or CAS PLUG
Attention: KM shown on instrument stored not only in instrument, but also in
CAS system, it can synchronize CAS and instrument and choose the bigger
one for standard. So, when you want change KM, you’d better take instrument
away from car, set CAS KM to 0,then read EEPROM dump from instrument via
BDM programmer, use File Change KM option to change instrument EEPROM
KM to a new KM, write back the new EEPROM dump to instrument and install
instrument on car
Read Code: Read DME and EGS code from CAS
Write Code: Write DME and EGS code to CAS system. Attention: We don’t
recommend general user write this code, the car will stop working if write error
code
Synch DME-CAS: Synchronize DME and CAS. Don’t use this function if all key
lost. If sometimes add key for CAS1/CAS2/CAS3 by OBD cause cars not start, then
you can use this function, refer Special Note 2
Synch CAS-ELV: Synchronize CAS and ELV, This function can be used when ELV

Special Note 1:Read/Write function of EWS support 0D46J mask and 2D47J mask
now. EWS support Read EEPROM, Write EEPROM, File Make Key, File Change KM
etc.
Special Note 2: Sometimes add key for CAS1/CAS2/CAS3 will cause car not start,
you need use these two functions: Synch DME and CAS, Synch CAS and ELV.
Running these two Synch-functions one by one after insert original key to
ignition switch, then take key off, insert again and try to start. If not start, insert
again and running these two Synch-functions again. Repeat steps until car
start. If you get error in synchronize progress, just ignore it and continue steps.

will show whether CAS4 is encrypted version or unencrypted version. (PICTURE
6.2-3)
(PICTURE 6.2-3)
OBD Read D/P and exchange CAS4. See the picture (PICTURE 6.2-4)
Function one: replace CAS4
First read and save the immo data of CAS4 and backup D-PLSH (EEPROM) and
P-FLASH, and then connect to a new CAS4 to write.
If it is an encrypted version of CAS4, you need to modify the ISN, click "encrypt
version" and then follow the prompts to modify
Function two: repair key function
The original key does not start
Original key not start issue almost belong to CAS4 encrypt version, unencrypt version
have very little issue like this,
The original car key is work normal before unlock CAS4/CAS4+, but after unlock or
add key, the original key will not to start the car. Put the original key into the device
coil and click on "CAS4 (5M48H/1N35H) fix start".(PICTURE 6.2-4)
If the new key does not start, the original key is normal. If it is encrypted version
check whether the ISN is correct, then change another key position and change a
new key close to ignition switch to match again. If it is unencrypted version, change
another key and another key position, put the key close to ignition switch to match
again.
The original key remote/keyless not work
1. One of the original key or new key is not work:
A) Erase the add key and check whether the original key work. After it is work,
close the new key directly to the ignition switch to let the car learn automatically.
After learning, all key and all function will work
2. Both the original key and the new key are not work:
A) Erase the new key, check whether the original key work, if not work perform
next step
B) Restore the code that was backed up before Unlock CAS4/CAS4+, back to
the interface (PICTURE 6.2-4), click "Restore Coding" to load the code that was
saved before the unlock CAS4/CAS4+, after restore code, check whether it work,
