VAG-COM/VCDS EVERYTHING

Your interface is RL, but I am 100% sure that this will help you

If this helped you, please push the "thanks" below

Thanks a lot for the help KenshinPT. I also founded here: http://www.digital-kaos.co.uk/forums...50/#post488533.

Ok then according to the transistor output schematic the four (4) transistors in the back of the interface are for K & L lines replacing SI9241EY chips in the pdf diagram. And the other two (2) transistor near the ATMega162V could replace SI9200EY can driver in the pdf diagram. I will like to confirm this too.

In this case typically one of this SMD transistors could be in short when the ATMega162V or GAL16V8 look for it.

I am also starting to read whole thread looking for more info.

I have 10.6.4 is it easy to update to v11+ or no advantage

Many thanks

In your hardware, you have 4 transistor for KKL but those 2 transistor you're saying that your cable has, are in fact diodes

Your hardware, have both chips for CAN (CAN controller and CAN Transceiver)

And you're right, those 4 transistores could be in short.

Good luck
Regards.

Yes, the upgrade is easy.

You need a programmer and the dumps.

If you were connected to the Internet and the program started to kill obviously working cable, it is necessary to remove d1-d3 files, and to replace "codes.dat" file.

Where are all this files located and where from we take ''codes.dat'' file to replace. Many thanks.

Well you have to make a back up after you install first time or if your tools it is erased, uninstall the softwear , erased all registry and the reboot. After this you can isntall it back
Good luck
For the peaple who do not using this every day, mu advise it is to install the softwear ( no internet connection ) then after you did a dignostic it is better to uninstall the softwear till you'll need to make another diagnostic in your car. When you need to make another dignostic you have to install the softwear back, do what you have to do and in the end uninstall the VCDS softwear till next time
Good luck

Thank you mattydr67. I found those files. I would still like to know more about those files madagan talks about... Does it worth deleting and replacing this codes.dat file ?

I just erased d1,d2,d3 after every diagnostic session before using internet in that computer. Atmega never erased.
Good luck

If the cable worked with this program well earlier. Now ceased to work. You already reprogrammed atmega. But the program continues to kill a cable. Then it is necessary to delete files "d1.bin, d2.bin, d3.bin" and to replace the file "codes.dat". They lie in folders near the set program.

Or to make how mattydr67 advises. It is a post number 2874.

I just erased d1,d2,d3 after every diagnostic session before using internet in that computer. Atmega never erased.

And you already tried to do so in version 11.11.3?
The program all the same tries to communicate with any non-constant IP.

I didn't tried becasue I don't have this version yet. I allready have 11.11.2 version and I can use internet connection in the same time with a diagnostic session.
I do not use any kind of protection ( nothing write in hosts file, no d1,d2,d3 erased, no firwall used, nothing, just VCDS softwear installed and this is it.
Good luck

Well I pass almost all night checking and testing everything in the board.

I check out the transistors and are ok!!!! Weird... but anyway.
I found that K & L lines arrives up to these diodes:



And continues to big signal diodes near these ones. After goes to the GAL16V8, I suppose this is the face erased IC. That contrast to the transistor diagram that you share me.

I check out the whole pcb and re-pass every solder of the main components in the front face, GAL, ATMega and resistors and capacitors near it.

With 7805 out resistance from +5V to GND is 2.5Kohms!!!!!!!!!.

Now interface starts, LED blinks red all the time, 5v is stable, 7805 get hot but not as before and I notice that ATMEga and GAL get hot not as 7805 but more than should be. In fact I got almost 80?C of the 7805, almost 60?C from ATMega and 50?C from GAL. Transistors, diodes and ICs in the back are cold.

Software still recognize interface but I got the following message:



Also USBView recognize interface and MProg recognize FT232RL.

Now I really confused!!!!

[tazman13]

I use a modded 11.2 with an interface with no GAL (help gained from here).

Should I be deleting D1,D2 & D3 each time?

Can any damage be done to my interface now that the STC and GAL are removed?

Also I am assuming for me to go any higher I would need a modded 11.xx and a higher than 1.84 dump?

(cable is just fine for me, just wondering)

Thanks in advance (cable is just fine for me)

Friends do you have any idea what could be wrong?????

[magadan]

...what could be wrong?????

In the first, cease to load identical photos, or reduce their size.
In the second, compare the diagram of your cable with datasheet a cable.
Of the third be convinced that you didn't make errors when "tuning" cable.
In the fourth, give a cable for repair to experts. It is very difficult to repair a cable if it is impossible to take it in hands.

Try to replace the GAL chip with jumpers. Replace ?tmega. Check soldered details.
I don't see in your photos, three jumpers which are necessary that the cable earned.

[KenshinPT]

I know this could be expensive, and this post won't help you with your problem... but if you want to keep things easy with VCDS, buy a cable with BL chip.

Why? Because you don't need a loader and BL dumps works on any BL cables...

Regarding your problem, I am also without ideas... So do what Magadan wrote

Good luck
