Hi all,
I'm racking my brain on this one. I have one key & fob that work and bought another key online cheap and was able to get it to work with the immobilizer so it can unlock manually and start and run car.
I've tried about 6 different key fobs (cheap ones and one original Audi used one). Long story shorter... my good fob is an 4D0837231M and I have three fobs that say they are 4D0837231M's. I can't get adaption to recognize any of them. I have a tool that can check the frequency and they are indeed putting out 315MHz like my good fob so I know they're transmitting something.
My Audi with VCDS Lite uses 35 Central Locking and Channel 21 for the key adaption. My steps are as follows:
1) Put good key in car and turn on but not start car
2) Read/Save Channel 00 to clear settings
3) Read Channel 21
4) Put 2 Test Value and Press Test
5) Press Original Key Fob Unlock Key
6) See "Recognized" in status above (changed from "Learn...")
7) Press new Key Fob Unlock Key
8) See no new changes (only see Recognized when known good key is used even if I reverse Order)
9) Press Save
Observations
A) When I check Measuring Block 007 (Original Fob always goes into slot of the number I type in. If 2, the display reads 0100, if 3 it reads 0010 and 4 0001
B) When I first read Channel 21 the Tool Tip in VCDS Lite says to set the number in Test for each key. I've tried that too and no real difference.
C) I've tried these instructions https://www.ross-tech.com/vag-com/cars/vw-remote-matching.html and they say to hit Save before pressing the fob Unlocks, but I only ever see the status change to "Recognized" between Test and Save.
D) The car never gives acknowledgement that it has learned key, even original good one
Hoping someone can help. Let me know if there's missing info needed. Thanks.
