problems adapting a new key with VCDS on 8P

[nick9one1]

I've got the full VCDS v11 and have followed the guide on rosstech for adapting a new fob (buttons only, not immobiliser).

.....

[Select]

[46 - Cent. Conv.]
[Adaptation - 10]

Enter channel "01"

[Read]


This will display the number of currently stored remotes in "Stored Value".
VCDS indicates that 1 fob is currently matched to the car

Enter your total number of keys up to a maximum of 4(including any existing keys) in "New Value"
I enter '2'

[Test]
seems to hang here?
Verify that the number in "Test Value" is correct.
test value never updates to '2'

[Save]
save button is greyed out, as I presume the test hasnt succeeded .

Then press and hold (for at least one second) the UNLOCK button on the fob


Does anyone have any suggestions?

erase the keys first then recode

Yeah that's what I do.

ok thanks, not sure what happened but the second fob just started working! I logged into VCDS again and it says 2 keys are paired.

Just need to code in a new immobiliser chip now... I've got as far as getting the SKC with commander, and successfully logging into the Immobiliser [25] Security Access with the pin.

I'm having this exact issue too. Car came with 2 keys and the spare works in the door and starts the car etc, but the remote doesn't function.

VCDS shows 1 key learned and I can't update the value to 2. Scared to erase keys in case any problems occur while programming and I'm stuck with no remotes!

Can someone 100% confirm that I have to erase the keys first, and if so, how do I do this?

2005 A3 8P 3d 2.0 FSI

Thanks in advance

You have no choice but to erase & add both keys.

 

[Gilb2406]

Thanks NHN. I did do it in the end. Car blinked to acknowledge both keys but key 2 still doesn't work. Very odd. Think I need to get a new remote on fleabay

I'm having the same problem - a good friend of mine who works with vags says at times, they just die

 

[Gilb2406]

Like everything I suppose!

Odd how the car recognises it when learning though!
