A4 Electric Windows

[robins]

Just back from Kazakhstan and had the S2 out of the garage for the first time in 2 months, gave it a good run but when I got home, parked on the driveway next to the wifes A4. I had some things in the boot of the S2 and needed to use the key to open it. As the S2 boot clicked open all 4 windows on the wifes A4 fully opened. What is even stranger is in order to close them I had to get her keys and switch the iginition on to power them up. So whats going on there? anyone got any ideas?

PS The S2 has an aftermarket Clifford alarm system and the A4 is a 2004 3.0Q Avant with the factory alarm / key fob which does not even have an auto window feature

hi rob
you'll probably find the a4 does have auto window feature keep you button pressed
on lock to take them up and unlock to take them down
as far as the clifford alarm goes the use a rolling code which might have just rolled
on to the code for the a4
i've got a laserline one on mine and when i reset it after an alarm
it sets the door bell off

OK thanks
Interesting about the auto window thing, have to investigate that when wife gets back from her last minue shopping panic. Can this be disabled? I figure if it happened once, it could happen again, but next time on some car park somewhere in pouring rain.

not sure if it can be disabled
maybe in vag com

Vag com , can disable this option , and even u can specified which windows to open and , close but i forget the information about it , i saw it in early a4 1998 it was enabled that the four windows opens when he unlock the car with the remote fob.

cheers

Here is some details how to solve it with Vagcom hope they are usefull.


46 - Central Convenience: K1-- KWP1281
VAG-COM works well. We've had some problems with errors while getting the Door-Slave part numbers. If VAG-COM errors out while trying to display the information in the "Extra" fields, go to the Options Screen and set "Char Int" to 0.

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 VAG-COM 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
for Adaptation Channel 62:

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.

Central Convenience Controller Coding:

State Bit Dec. Function
OFF 0 1 Great Britain- alarm system (only with bit 4)
OFF 1 2 flash on when arming/unarming alarm system
ON 2 4 selective locking 1 door/all doors
ON 3 8 activate alarm system
OFF 4 16 rear unlocking block via speed
OFF 5 32 locking via speed
OFF 6 64 comfort functions with remote (adapt in ch 62!!)
OFF 7 128 right side steering
OFF 8 256 avant (glass break sensors in rear side-and rear
windows (if error: safe-LED constantly lit ))
ON 9 512 1x flash when lock with remote
ON 10 1024 horn sounds when lock with remote
ON 11 2048 door/window-logic ( ignition off: No open door
el. windows works 10 min )
OFF 12 4096 normal/????-alarm system
ON 13 8192 No SAFE-function USA only
OFF 14 16384 insulate-glass PR-nr 4KR/4KV

Again, we can verify that we did this correctly by adding up all the decimal values for the bits that are ON:

4 + 8 + 512 + 1024 + 2048 + 8192 = 11788.

Now notice that bit 6 with a value of 64 and function "comfort functions with remote (adapt in ch 62!!)" is OFF !!! So in order to turn this ON, we need to add 64 to the original coding. 11788 + 64 = 11852. Recode the module with that number. Once you do that, the options in Adaptation Channel 62 should take effect, and you can change the value there to "fine tune" the features..

If you wanted to add "locking via speed" (where the car locks itself as soon as you reach some low speed), you would add 32.

If you wanted to turn Selective Locking OFF, (so the entire car unlocks with one press of the unlock button on the remote) you would subtract 4.

Thanks kninio. Had to read it a few times, but I think I understand. I only want to disable the "windows down with remote" so need 93 (01011101) instead of the original95 once the comfort features are activated. As this is a right hand drive car I assume I also need to add 128 = 11980

any time mate
