# Thread: Question on VAG-COM change

1. I have a B6 Audi A4 Avant and I'm using a VAG-COM to make changes for the first time. I have a questions about the format of the coding.

What I am trying to do is set my car so that I can roll up the windows and close the sunroof via the remote.

Here are the details from the Ross-Tech site on the procedure:

******

There are numerous options/ features that can be set. These are controlled by the Coding and in Adaptation Channel 62. When we published a simple table, many people didn't understand it, so here's an explanation:
Let's look at Adaptation Channel 62 first (it is simpler, fewer bits than the Coding). The original value in a US 3.0L model is 95. Both a real VAG tool and VCDS display these values in decimal. 95 decimal is 5F hex, or 01011111 in binary.

Value: 01011111
Bit: 76543210

Now we can correlate the bits with the chart
State Bit Dec. Function
ON 0 1 windows up with remote
ON 1 2 windows down with remote
ON 2 4 windows up with key in lock
ON 3 8 windows down with key in lock
ON 4 16 sunroof close with remote
OFF 5 32 sunroof open with remote (does not appear to work)
ON 6 64 sunroof close with key in lock
OFF 7 128 sunroof open with key in lock (does not appear to work)

Also, you will see if we add up the decimal values for each of the bits that are ON, we can verify that we did it right because we got the original Adaptation value of 95.

1 + 2 + 4 + 8 + 16 + 64 = 95.

By now you're likely starting to wonder why "Windows with Remote" stuff doesn't work since the appropriate bits appear to be ON. To answer this question, we need to look at the coding the same way. The original coding in this car is 11788 (decimal). That's 2E0C in hex or 010111000001100 in binary. Again, we can again correlate the binary bits with the function table, just like we did above.

*******

In VCDS I see two fields I can update before I click the button "Do It!"

Software Coding (0 - 32767) : 03200
WorkShop Code (0 - 99999) : 20111

To set it like this:

State Bit Dec. Function
ON 0 1 windows up with remote
ON 1 2 windows down with remote
ON 2 4 windows up with key in lock
ON 3 8 windows down with key in lock
ON 4 16 sunroof close with remote
OFF 5 32 sunroof open with remote (does not appear to work)
ON 6 64 sunroof close with key in lock
OFF 7 128 sunroof open with key in lock (does not appear to work)

Do I change the first of second setting?

Thanks for helping a VAG-COM n00b!

3. A full scan, eh? This is the closest I could find - the Auto-Scan.

Is this the scan you were referring to?

4. Thank you for posting a full Auto-Scan.

The current Soft Coding of the Central Convenience Module is 12044. Change the soft coding to 12108.

+00064 - Comfort Function via Remote Control (not USA)

12044 + 00064 = 12108.

5. Thanks! I'll give this a try and post my results.

6. Hi Jef, I've made the code change to 12108 and I don't get the windows to roll up or down with the remote. How can I confirm I'm doing it right?

Thanks,
Dub

7. I think you want 16242. I can't rember why, but for some reason that sticks in my head for module SOFT coding for your car.

8. Looks like there might be some Adaptation values as well. Go into CCM module, Adaptation channel 62, what is the current stored value?
