VAG-COM/VCDS EVERYTHING

812.4 upon test shows that:

I really don't know but for me this message "SHORT to +12" sounds like a short circuit in K1 LINE.

Also the transceiver MCP2551 or the CAN controller MCP2515 can be damaged.

(some clone cables use tranceivers and CAN controller from other brand thus the reference should be different)

Check your cable for any short circuit to 12V.

812.4 upon test shows that:

first of all you didn't flash atmega, if you did, it would say version firmware 1.81 that's one thing, other thing is that you have damaged transistor for k-line, very common thing for these interfaces

Do you have the HU changed in your car?
I mean don't you have the original HU?
Try to reade here:
Ross-Tech: VAG-SAVER
I did one by myself from a ross-tech idea. I'm using it before plug the tool into the OBD II socket. It has bicolor LED green/red. When you have a short to +12V the Led become red, when everythings ok the led is green. One of my friend it happend to have an ABS issue and that it made a +12V short too)
Good luck

What is the Mprog procedure? I thought that was it.

Interface was working fine and one day I got this message and it stopped connecting to any K-Line. It connected just fine on CAN bas cars though.

Then it stopped working alltogether.

So the 812.4 interface is toast? Do I have chances to revive the 704 which worked just fine for 2 years now?

That's a cool device. I've never seen one though and I doubt anyone would ever use it. They just plug their diagnostic interface and see if they can get any codes out of the car.

i made it my self little bit different, more raw you can say, it's just male obd2 plug with 2 wires connected to pins 4 and 7 terminating a diode led, if led lights then don't plug diagnostic interface ie. you have 12 V on k-line

Guys,

programming the ept file with Mprog..... what exactly is it? Does it program the atmel chip or what?

I use it in every car not just on VAG one.
You never now and I saw a lot of demaged tools.
So never know what gone hapend.
If I'm using the Vag-Saver , I saved ( like when u use condom )
Good luck

Mprog is for flashing FTDI eeprom.
You need to reprogram atmega with other tool for example ponyprog, read all posts and you will find the way how to do that.

Maybe idea is buy genuine one and make copy and sell dumps here for members? I will be intresting just to get update. Let see how many user will be intresting.

[caveman_nige]

[Spacewalker]

No a sale of course. Meens buy toogether. Bad idea ?
If no - apologies for this. Not a good time to post info.

hi i have a chineese dual k 912 it worked just great then quit says licsene revoked can some one please help me. i have read threw this whole form so i did look. where to look or how to remedy this. vw tdi 2005. thanks. you may email me if so

[hevi]

First remove stc chip like i marked in pic then you will probably need to reflash ftdi eeprom after that reflash atmega with 908 dump (flash and eeprom) configure security bits and you will be good to go. I had good experience with that kind of hardware.

All you need: Dump VCDS 908.0: http://rapidshare.com/files/41605396...ash__908.0.rar

FTDI Eeprom for FT232BL and FT232RL: http://www.digital-kaos.co.uk/forums...tml#post816515

Just to keep in touch...
First i removed the STC chip and pluged to car...cable recon as serial...uninstalled and installed driver and cable recon as ross...still shareware.
Then reprogramed again FT232BL and cable now is not recon in Windows XP.
Will try to reprogram atmega and tell you result later...

Just doing this steps to se results...

Thank you again

edit: do i need at the end flash 1.83 or can i stay at 1.81 for 905

Hello guys!

Does someone know if I can use a china clone vcds 908 with romanian version of 908?

Thanks

I just can't solder the 4th pin on the atmel. I don't have so thin wire. The rest I found where they bridge on the board and soldered the wire there. The 4th one.... Is probably not connected anywhere.
