VAG-COM/VCDS EVERYTHING

**DreamLand69** · 19th June, 2018, 09:30 AM

Can I use different updated vcds through the kolimer method? (The same software on the same laptop)

Thanks

Yes, you can install multiple versions of vcds in separate directories. Must use compatible loader with flashed firmware/eeprom to all vcds versions if you don't want to reflash loader before using vcds.

hello, help find schema to repair my old od2 thanks

Does not look as vagcom...looks like kkl cable??? Maybe I am wrong, but share pics with the other side.

OK alzxm1 and thank you, here is the photo.

Maybe this cable was able to run 409.1 vag com , but won.t work with vcds. Buy a new a full cip cable, this is antique hardware, no offence.

Hello guys,

So, a week after making my interface stable by resoldering the Atmega, it became unstable again (it did not repond to queries from vcds or the hw identifier tool (while powered by 12Vcc).

As a result i've bought another Atmega, soldered it in, programmed it and surprise suprise, now i got a short to ground on K1.

I've replaced all the transistors (MMBT3904) with new ones, checked the film resistors (473/683) and they seem to be ok.

I've checked voltage between odb2 plug, pin 7 and ground, and got 0.6V

What else can i check for this `K1 short to ground` issue?
(The led blinks red since the interface is powered up and remains red after testing in vcds. Power supplied is 12Vcc power supply, so no connection to a real car.)

Thanks!

can be that you have short on k line inputs to atmega or PLD.. cant see interface photos..

**shd** · 26th June, 2018, 11:40 PM

There was a short due to 7805 pass through holes not having enough/good conductive material, so the back of the pcb did not receive +12Vcc. Now it seem to work ok. Thanks xoom!

I just managed to crash my clone interface when VCDS v18 offered to upgrade the firmware from 1.84 to 1.96 and the firmware upgrade process stopped at 8%.

Now VCDS doesn't recognize the interface at all

What can I do?

**PremierD** · 27th June, 2018, 04:27 PM

And you are totally surprised by this mate ...??

**sashat720** · 27th June, 2018, 06:08 PM

I have bought the following interface which has a ATMEGA 162:

2018-06-27 18.35.38.jpg

2018-06-27 18.35.57.jpg

It doesn't get detected using kolimer's VAGCOM_HWType.exe.

What can I do to make it work with the kolimer's Loader v6.3?

Ia a clone, OK? NEVER use a clone with other original \/ ( |) S for update or using.
In your case use AVR USB programer and restore your's cable.
Read this from page 1 and see how to do this.
Or..search fantomel's procedure.

I did exactly what you said (AVR USB programmer) and it worked

Thank you!!
