    Hi,

    I've just picked up a cheap 51 plate A3 130tdi.

    The car came with 2x keys with a light button, but no radio function. I believe anything after 1997/1998 should have a CL pump that supports RCL, so I'd guess that a previous owner had lost or broke their flip key, as one wasn't supplied.

    Could someone confirm that ALL 2001+ models should have RCL.

    Secondly, I've searched on this forum and found a file that shows the softcoding options for the central locking, however the link is dead. Does anybody have the below file, that they could send me? Just incase I need to turn this funciton on, in the event it wasn't dealer-activated

    A3 2000+

    Thanks

    Hi

    From what I remember you can make the ECU learn a new open/close remote by putting a valid key in the ignition and press some buttons on the new remote fob. I did this on my old A3 (98 model) with the two button remotes.

    But that's only for opening/closing the car- which is what you're after.

    Perhaps then you can get a cheap/stolen/lost/pilfered remote off ebay and swap the key blade and RFID transponder?!

    Hi, i don't want to hijack this thread just won't open new one because I have the same question as jonesy.
    I just bought a3 8l 2002 1.9tdi 74kW. It was a good deal and the car is in super condition, but no remote locking. I got two basic keys no flip no remote funktion just light bulb on one, one plastic key and code on paper in plastic.

    My questions are:
    Is it true that my a3 has RCL, because above stated that all 2001+ models have? (also i noticed something like ir reciver just beneath windshield where central ventilation vent grill is)
    If it is true, what do i need to watch when buying geniue used key on ebay, does freq of transpoder metter or not, can i buy for example used a3 8p 3 button flip key (like this: http://www.ebay.com/itm/AUDI-A3-A4-...603?pt=LH_DefaultDomain_3&hash=item2ede3bd0a3) ? Or just 8l type will work?

    And at least here is a picture of my key:
    IMG_1060.JPG TransponderCapsule.jpg TransponderOld.jpg

    Is this capsule what i need to transfer to key i buy, cut the new blade, sync it to the cars central locking and everything will work or i'm badly wrong? Please help. thanks.

    As far as i know 8l has 434mhz frequency and 8p something over 800mhz. So for 8l something like this should work
    http://www.aliexpress.com/store/pro...31R-model-4D0-837-231R/117375_1830602129.html

    If you need the rest of the key then something like this can help
    http://www.ebay.com/itm/141541768301?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT

    Capsule is for the immo without it the car wont start and yes you can just transfer it to the new key.

    Im getting the parts in a few days so than i can say more from personal experience :).

    Thank you for quick reply, please write is everything ok when you'll be done.
    I also own a3 8p in familly and on that key is written 434 mhz so that why i was asking can i use 8p key from ebay.
    How did you know your car have rcl support, did you have to look for your cl pump nr. or some other way.

    Hey, my A3 8l came exactly with the same key as you have, fixed with with only IR reciever and my goal is also same. I'm trying to find keyfob that supports my car and get remote locking working. First of all you need to see if your central pump actually supports it.

    8L0 862 257 DWA and remote (433,92 Mhz)
    8L0 862 257 B DWA and remote(315 MHz)
    8L0 862 257 D just remote(433,92 Mhz)
    8L0 862 257 G DWA and remote(433,92 MHz)
    8L0 862 257 K just remote(433 MHz)
    8L0 862 257 M DWA and remote(315 MHz)
    8L0 862 257 N DWA and remote(315 MHz)

    Secondly you need keyfob that matches the frequency. I have 8L0 862 257 G and need 433.92 Mhz keyob.

    4D0 837 231 (old) 4D0 837 231 R (new) 2(buttons) 433 MHz
    4D0 837 231 A (old) 4D0 837 231 N (new) 3(buttons) 433 MHz
    4D0 837 231 B (old) 4D0 837 231 S (new) 2(buttons) 315 MHz
    4D0 837 231 C (old) 4D0 837 231 Q (new) 3(buttons) 315 MHz
    4D0 837 231 D (old) 4D0 837 231 T (new) 2+Panik(buttons) 315 MHz
    4D0 837 231 E (old) 4D0 837 231 P (new) 3+Panik(buttons) 315 MHz

    According to ETKA i need either 8l0837231A or 4D0837231R fobs that should be compatible with A3.
    However i've read people getting 4D0837231A to work with 8L0 862 257 G which means only frequency matters?

    I have ordered this http://www.aliexpress.com/item/Repl...0-837-231-R-4D0837231R-For-A3/1947862762.html

    New blank key with all the internals for 20$ seems bargain but it won't come with Audi logo.

    OP: Default software coding for A3 is 13130 (i'm not sure if it includes radio) however it includes Central locking + Alarm + Keyless entry

    Software codings:
    1 Rear boot unlock & opened (only some models e.g A4)
    2 Flash indicators on activation of alarm 2
    4 Security central opening (drivers door only opens not passenger) with ey
    8 Anti-theft alarm switched on
    16 Cabriolet functionality on (reverse pump direction)
    32 Auto lock doors when car goes above 15mph
    64 Comfort opening/closing of windows
    128 No ultrasonic installed (cabriolet has no ultrasonics)
    256 Unknown (rear boot logic with remote A4 ?)
    512 Radio control close confirmed with one flash
    1024 Anti theft alarm set confirmed by horn beep
    2048 US window logic (Power windows do not work once door opened)
    4096 Radio control open confirmed with two flashes
    8192 Radio remote contro opening/closing activated
    16384 No Security central opening (drivers door opening only) with remote

    I'll let you know if my key works when it arrives. You also need to know SKC code to pair new IR with car or you can just use old one.

    So i can report tinostp that the remote works perfectly. The whole key looks not as high quality as audi but is cheap and works.

    I can confirm that pump 8L0862257G is compatible with 4D0837231R and it works flawless.
    (i used to have some weird aftermarket GT Cobra keyfob that worked on 433 frequency)
