VAG-COM/VCDS EVERYTHING

[pacomasi]

Hi, you could try use newer vcds loader v1.10 to try , EST software this period not work very well, waiting for update newer

Where can I find vcds loader v1.10?

Hi guys,

So after successfully updating my first vcds cable (which had programmable headers), I'm now trying to update an even older one for 2009. While opening up the PCB I found out it is based on ftdi+atmega, it also seems to have a STC chip. Could I be able to use EE_Write to program it via USB so I won't need to solder cables to it ? It doesn't have programmable header pins like the more quality ones. Pics below..

Thanks

Just try with EEWrite. If it doesn't work it will report it. Then you have to solder those couple of wires

[stonecoldro]

@H2Deetoo, unfortunately EE_Write didn't work for me. I've tried it using your previous tips: install original vcds version and run "Test" to unlock Atmega, connected to the car's CAN port (for 12V), then ran the software. I get "No response" - please see screenshot below. I guess it's soldering on the bench for me now .

Does anyone has a schematic for it ? I found some tips on another forum that mentioned soldering directly to MCP2515, not sure though.

Hey, your board has got some empty slotds for pins marked with "G T R U" letters. I think you need to use multimeter to check if contacts on these slots point to correct connections...

In fact, it's OK to solder directly to MCP2515. It's even easier to do that, because Atmega legs are tiny. Personally I have done that

You need to solder (before doing that, check those empty slots if they point to these contacts):
RST - Atmega leg #4 (the only thing which needs to be soldered to it)
MOSI - MCP2515 leg #14
SCK - MCP2515 leg #13
MISO - MCP2515 leg #15

GND - anywhere to Ground (USB is fine, but again, check those empty slots, one of them should be ground for sure!)

You can safely skip soldering VCC as it's unneeded. Use +12 V external power on the OBD connector 16 pin (and #5 on ground) to power up the interface while programming.

Also, I would suggest soldering in a protection diode while you are in there.

BTW, your interface soldering quality looks disgusting.

Empty slots are not for programing Atmega. Soldering wires to MCP is the way to go, RES will got to Atmega.

Hello
I also ordered the Hex V2 adapter from Ali. Unfortunately, the same problem with K1 short to + 12v. Has anyone solved the problem? Thank you

[obd2cartool]

Hi, your V2 I think cant fix, they not use Atmega chips

[zoggermaster]

I Think only the Transistors are damaged. I Have ordered new Transistors.

[hid3]

Transistors can bea easily soldered out and checked with multimeter. Have you already done that?

[zoggermaster]

Transistors exchanged, but problem persists. Then the problem seems to be somewhere else. All resistances are ok. So it can only be on the chip itself.

Maybe someone have software for this cable:

Cable with that ARM chip ( HL008 )

In the begining it was with damaged FT232RL chip.. replaced that and tryed with supplied soft (16.8.3) but it shows not activated:

It read serial from this cable but shows that interface not found:

Anyone have more versions that work with that type hardware?

Hi friends. Can someone help with a problem that i have..?
Problem: audi a4 2008 year use to have symphony3 media unit but someone changed to concert3.
Concert3 working, but cd doesnt work becouse car still see symphony unit that have cd 6cd..
When i do diagnose of 56-radio, car see symphony 3 unit. How to recode system to concert3??
Thank you in advance..

Interfaces with ARM CPU will never be freely supported, because they have china firmware.

I know they have custom FW.. im not asking about firmware. Im looking for Software.. just to try and if its not working just toss it
