VAG-COM/VCDS EVERYTHING

[liviudiaconu]

Tried viceversa too?
Move components from bad to good and see if good remain good?

You changed "important components", i undestand CAN 2 pcs ICs, Atmega, Qtz, maybe GAL...
But the same issue can be generated by a "passive" component like resistor, capacitor OR...PCB? Or soldered wires? etc...

Try measure voltages first on CAN Lines:
CAN_H - GND = 2.5v
CAN_L - GND = 2.5v
measure resistance between CAN Lines(not powered cable):
CAN_H - CAN_L= 120ohm

Hi friends. Maybe someone knows what is this capacitor? It is broken and I want to know witch capacitor to buy.

Is ok to order a vcds from obd2cartool?
I found a HQ vcds that support Long codding.
V16.8

Use 12 µF SMD capacitor.

Yes you can buy this 16.8 "Do it yourself" Interface with programming pins (Model: OBD649) and reflash. You need an USBasp programmer.
Or use it with the supplied 16.8 crack Software.

Thank you

Use 12 µF SMD capacitor.

But how much volts?

Different cars and every car was was after 2010 y. Problem is strange because I change almost every important component from working cable to non working but never succeeded to repair them! I have both version 0x44 and 0x46. I try several times connect disconnect check can-H can-L connection but nothing. I noticed that also some people have this problem but no one found solution. Once time even I bought 2 pcs chinese cables (red one) with this problem it was 15.7 version, one ot them has this problem!

I had the same problem. I returned version 17.8.0 VCDS loader V5 and now all worked .

Between 6-10V should be ok.

try 100 nF - it's not critical because it's between power supply and ground…..

Maybe somebody could point me in the right direction with the folowing:

I have a HW 44 cable with stc chip (now removed), the same as found on page 3 in the guide that comes with kolimer packages. (Hardware Type HW 0x44Identification : ATMega pins 34 and 35 must be connected to GAL chip.)

Have tried to use the VAGCOM_EEWrite methode but didnt work, so i read almost this complete thread and comprehended that i also needed to cut the STS cip on line 9.
Tried to do this but it failed and i removed the chip in completely.

Question> Do i need to remove also a few other transistors/resistors as stated in this forum? Wich ones because for an example R51 isnt there only R50. Anyone familiar with this board?

When connected to VCDS or VAGCOM_EEWrite.exe i get a no connection error. VCDS does recognice the cable like it is now but it says it's not connected to the car even though it is.

Do i need to flash it with a usb tool? With one can i order best?

Here is my board with the ptc already removed...

[belkor]

where you removed STS chip try to clean better .....seems to make contact and try:
plug in your cable into OBD socket
open MProg3.5 ...click Device -- Scan.....Number of programmed devices=1.....Tools -- Read and Parse......File --Save(save backup)......File --Open and load ftdi_mprog_BMBL.ept.......Device -- Program

[hid3]

Remove the excess solder.
R50 must stay in place.

Thanks @hid3 and belkor. Done now. So to flashing of chips is required? all can be done trough the USB cable?
