How much do you know Launch x431 v?

Launch X431 V is a new diagnostic tool released by Launch tech. It’s composed of an X-431 V pad computer, a protection sleeve, a DBScar diagnostic connector and many OBD1 to OBD2 connectors. Communicating with your car by DBSCAR connect via Bluetooth, it reads DTC and does full system diagnosis on the car through the X431 Pro Pad for full car models. So, it successfully replace X431 Diagun III or X431 IV. Meanwhile, taking advantage of mobile internet, it integrates more application and service, such as creating maintenance data base and case library, providing instant maintenance information, establishing public and private maintenance social circle etc. As a result, it builds a broad vehicle diagnostic community, which helps you to share vehicle maintenance knowledge online, exchange vehicle maintenance experience online and provide vehicle maintenance related service support online. This will be another revolution raised by Launch in the vehicle diagnosis industry.

Correct Mileage In BMW,Xprog Or R270/260?

I’m often reading about Xprog, R260 and R270. Whats the deal about these tools?

I tried so search and read about these tools but this confused me. Can someone explain me short and effective the difference and pros/cons about these tools? Maybe this could be a good sticky for new users.

My goal: correct mileage in BMW from 2000 until at least 2010.

Here is all i found in the CT community. Big thanks to all contributors!! I benefit a lot from this.

Xprog is a universal programmer for various chips in automotive and many more…

R270/260 is based most on BMW and MB immo systems+dashboards+some have function for erase 35080/35160 chips too…

both are very good programers and you need them both in this busines..

1 tool is not enough
R270 have the advantage to clear m35080 eeprom
R260 is more safe in MCU
Xprog is a good tool for many chips and mcu
all are Chinese
if you can pay more, i suggest you to buy VVDI Prog 

Among ecu programmers, vvdi prog should be the best choice because

  1. faster to clear 35080, 080D0, 160D0 (within 10S)
  2. more stable than Xprog-m to read MC9S12 series chips
  3. faster to attack MC9S12series chips
  4. less error than others to read some EEPROM that Orange 5 fail to recognize
  5. with voltage attack function for use
  6. with CAN bus, K-Line for use

Also, most tools from china are clone while this VVDI Prog is made in the Xhorse company where produces vvdi tools. So, the quality definitely is no issues i think. See the PCB in mine.


Here is XPROG-M, Carprog v8.21, R270 – read & erase BMW EEPROM M35080
. Wish this helps someone.



Read / write / save BMW CAS4 Via VVDI PRO Step Guide

Here is a tutorial of using xhorse VVDI PRO programmer to Read / write / save BMW CAS4 with highly secured MCU MC9S12XEP100 Masked as 5M48H inside

Main step guide below:

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.
