Hello!

Fuse settings not depends from the Interface version. It depends only from the type of firmware. The old public firmware has 256 word bootloader size where BOOTSZ0 is programmed and BOOTSZ1 is unporgramed. The newer firmware for FTDI RQ has 512 word bootloader size where BOOTSZ0 is unprogrammed and BOOTSZ1 is programmed. Any other fuse bits are the same.

The screenshot about fuse settings posted by alexm1 is good for all public firmwares. All free/public firmwares (including the fw for 11.11.0 you posted in #4185) are old type firmware with 256word bootloader size.

Regards

Hi, in Auto HVAC, is there a way to correct an offset between displayed temperature request and the actual cabin temperature? To get normal comfortable temp I have to dial in something like 16.5 - 17 degrees C which feels like 21 or 22C in reality. The car is Audi A3 8PA 2006, there are no fault codes in the HVAC system.

You will not find an answer in this thread, here we talk about how to fix/update vag com/ vcds cable.

I can't find eprom flash and config dumps for vcds atmega 162 use for xprog. Please help with dump 11.11 or any other english version, my interface ftdi RL type. Thanks

**leader79** · 17th June, 2014, 07:56 AM

First use a the "Shearch thread" function above before asking. You can found it easy.
The dump and loader for RL cable is shared many times, it's unnecessary to repost it on every 10 pages....

**athlonxp** · 17th June, 2014, 09:18 AM

Yes I found many dumps for atmega, but xprog need config dump and flash eprom dump not like with ponyprog.

Can vcds read edc17 mileage ,if so what channel is used.

**andrius** · 19th June, 2014, 08:32 PM

configuration bytes are simple, you may use them from any existing format

or use HEX file, or just simply tic needed

there are some in this thread too

for EDC17, yes it may show km

and much more

just need correct channels, and logins

and YES EDC17 has logins too...

No, cannot , but you may check the DPF regeneration count and do yourself some math, you may find what you are looking for; DPF should not been deactivated and in good working condition, otherwise make no sense.

Hello fellow forumers of this educational thread!
I have a perfectly working VAG COM 12.12 with the original release software.
Now, the question is: Can I dump the micro with Xprog-M v5.50 without breaking it?
Any ideas are appreciated.
Thanks.

Firstly check if it there is ATMEGA or NEC.

Hi!

You can not read the content of ATMEGA with AVR programmer becaue is read protected.
If you try to read it out than you will receiver dummy bytes instead of the real content.
Of course there is at least 3 secret methods to read/rebuild the eeprom of the ATMEGA (the application area is not important) without AVR programmer but is not public (and I hope never will be public).

I bought a VCDS 12.12 clone and now it says it's not registered. I think the internet was on and it updated the firmware? Is there a fix for that?
Thank you!

The fix is to buy another and make sure no internet next time
