How to read Mercedes W203 1J35D MCU with xprog-m 5.0 [pictures]

I have managed to read 1J35D MCU of Mercedes-Benz W203 EZS with Xprog-m 5.0 ECU programmer.Here are some useful tips/ infomation for sharing. Wish i help you out also.




The China Xprog-m i used

XPROG Connexion

Also, someone in a forum says the best way to read this MCU is to use R270 BDM programmer - it's so easy to read this MCU'S. He said he did it many times always with success. I will try it if possible.

TCS-CDP pro clone can't read BMW ECU [user solution]

I have recently purchased new TSC-CDP pro from China. Software supplied with its softwware 2014 release 2. The software installed and activated OK. i tested the unit and it passed the test OK; but unluckily, it does not communicate with any car... only use USB cable ( not bothered with Bluetooth). After vehicle selection, the system cannot read ECUs and generates silly error messages "Vehicle not responding (Fahrzeug antwortet nicht)".

Error message:
Initiation of the tester... YES
Searching for the interface... YES
Establish communication... NO
(ISO 157656-4, SAW J1939-21)

Vehicle not responding
The vehicle is not responding to the diagnosis inquiry made. Please make sure that the tester is correctly connected to the vehicle and that the ignition is turned on, and try again to establish communication. If communication fails again, it is possible that the diagnosis function is not supported.

2014 release 2.
The software installed and activated OK...and tested the unit and it passed the test OK
Hardware: (new VCI), Serial No.100251, eOBD 114, Firmware version 1423.


* First modification- FAILED!
I tested on Mercs and BMW. I opened the CDP unit and observed that two boards are not connected correctly. So, I pushed them together. This has improved a bit, as the unit now makes a clicking noise when connected to a car. Even can read the VIN, but on BMW failed to read the ECU. I will try later on a different car. But this is already a bad news (no BMWs).

Then, I contacted the supplier and was informed that this TCS-CDP DOES NOT WORK with BMWs and Mercedes cars !!!!!

* Second modification- FAILED!
Then i was told that "the device actually does not work on any vehicle that uses SAE J1850 (PWM and VPW) because it has a fake OKI m6636 or it does not have it at all... The OKI chip is only for cars that support the PWM/VPWM protocol like Ford. BMW didn't use the PWM/VPWM protocol." And this user did fix the problem and used the same interface for all BMW cars..TCS CDP interface, removed from old devices like tv´s, radio´s etc. check all solder Joints of all components (especially relays)..

But I didn’t try that, and decided to purchase another TCS CDP from a different supplier. White this time... When it arrived I tested it immediately on the same BMW 7 E66… and guess what …. Same problems remained.
New TCS CDP white:



***** Third modification- Successfully SOLVED finally!
the problem with the m6636 is in the cdp pro, not in cdp+. replace the 2 diodes (D701 and D703) with 1n4148. back the pcb.

Then gained the communication with BMW car which I could not communicate with before.
So, well DONE!

Ps. To avoid problems above, i recommend you all to buy the OK version as my friend used, without any issues so far. you can see his PCB below. He bought this from
It is said that it’s the best clone CDP from China


(someone also said a 100% solution in mhhauto forum:
have to install
Microsoft .NET Framework 3.5
Microsoft .NET Framework 3.5 Service Pack 1
and all is 100%

But i didn’t tru it. Maybe it works!

How to use E-sys ENET cable to change BMW F series FA (VO)

The following will teach you How to use E-sys ENET cable to change BMW F series FA (VO) step by step.


Tool needed:
E-SYS software
A laptop running Win XP home

1. First we need to connect to the car

2. Select the target chassis. In our example we will use the BMW F10 chassis

3. Go to “expert mode” -> then “coding”. Click read under vehicle order to read FA from the car. Click edit.

4. The screen will automatically change to the FA-editor. Right-click on FA, and select “calculate FP”.

5. Once finished, vehicle profile is shown on the right side of the screen. Expand the FAList on the left until you see SALAPA-element.

6. Delete or add FA from the bottom left window, and click the apply changes icon.

7. The new FA must be verified before it can be written to car. In order to do this, Right click on FA and calculate FP again. If the FA you entered is wrong, an error dialog will pop up. Anything other than the codes on the VO list will display an error message. After FP is calculated, save the new FA.

8. Go to Expert mode –> VCM. Load your saved FA file, right-click on FA and calculate FP again.

9. Click the VCM tab, and click write FA FP. The new FA will be written to the car but won`t display any message so if you clicked once, no need to click again.

10. Click on “read FA FP VIN” button and check FA to make sure changes are saved to the car.

All done, you have now successfully edited VO.
