Xprog, R280 and VVDI Prog BMW CAS4 5M48H Read/Write

It’s known to all that Xprog, R280 plus BDM programmer and VVDI Prog all can read and write BMW CAS4 5M48H. So, which one should you take for CAS4 5M48H R/W? Here is the buying guide of ecu programmers for 5M48H R/W.



(Cheapest) Option 1: Xprog v5.70 read/write CAS4 5M48H

Xprog price: $139

Note: 5.7.0 is the only version XPROG-M can decypte BMW CAS4


5M48H R/W process:

Run xprog software

Click on New

Read 5M48H

Xprog-read-write-CAS4-5M48H (2)

Xprog-read-write-CAS4-5M48H (3)

Then write 5M48H

Xprog-read-write-CAS4-5M48H (4)

Xprog-read-write-CAS4-5M48H (5)

Xprog-read-write-CAS4-5M48H (6)

Again, click on Read after verifying the device

Xprog-read-write-CAS4-5M48H (7)

Xprog-read-write-CAS4-5M48H (8)

Xprog read and write CAS4 5M48H successfully.



Option 2: R280 plus CAS4 programmer read/write CAS4 5M48H

R280 plus price: $469


5M48H R/W process:

R280 CAS+ IN CIRCUIT Programmer read 5M48H eeprom

Cas4 programmer read MCU 5M48H







R280 programmer check EIS/CAS odometer






(Best) Option 3: XhorseVVDI Prog Programmer read/write CAS4 5M48H

Vvdi prog price: $429


5M48H R/W process:

Open VVDI Prog software, select type, manufacture and model as MC9S12XEP100)

Click “Wiring Diagram”

Maximize wiring diagram: right click and select “zoom window”, then pull down window.

Follow the wiring diagram to connect CAS to the VVDI Programmer.

Start to connect the cable.

The left zone is done, next is to do the right zone.

In this wiring diagram, it only need to remove one 0 ohm resistor to read out data, but one CAS ECU structure is different another one, some needs remove more electronic parts; we will show how to do in the other videos.

Next is to remove this 0 ohm resistor.

Wiring is done, 0 ohm resistor is removed

Plug adapter into VVDI Pro.

Close wiring diagram.

Select “New” – ” Read”

You see it is reading data very fast.

Reading data successfully, click “Save”

Next is to check data.
Open the data, drag the mouse to check, okay, data is all read out, close it.


Attach photos of the reading procedure

In sum,

Xprog 5.7.0 is the only solution for BMW CAS4 among Xprog programmers; and it’s the CHEAPEST compared with vvdi prog and r280 plus.


Vvdi prog programmer is the best choice; cost-effective! It’s worth the money coz it covers the most chips (much more than r280)


How to set up R280 CAS4+ BDM programmer software

Here is the software installation guide of R280 Plus CAS4 BDM Programmer for BMW Motorola MC9S12XEP100 chip (5M48H/1N35H).
