Carprog Antena A3

[hbalazs]

Remove this capacitor (or change 470pf) and change 10nf ok.Work and read write transponder

hi lads i have carprog original but have clone antenna and seems crap

anyone tried making one from say fiat immo ring

[underworld1991]

PLZ CAN CKARIFY BETTER I DONT UNDERSTAND
I TOLD MY CLONE CARPROG ATTACHED THE ANTENNA OR NOT ATTACHED SAME MESSAGE NO ANTENNA ATTACHED
WHERE WILL BE THE PROBLEM
THANKS

i just removed like in picture and replaced the resistor only i did not do the caps and it is working fine for me

carprog antena work only in 4.74 and 8.21 version and never to another version.can use original antena from carprog kit,ist very good.
solution:
carprog antena.jpg
1. replaced 150k with 15k (resistor)
2+3+4 here we need to solder a capacitor with aproximately 6-7 nF(put one or combine from 2-3 capacitors)
5. removed 100 nF capacitor
6. removed 100 pF capacitor
in position 2 it was a 2.8nF capacitor
in pos 3 it was 0.5 nF cap
in pos 4 it was 100 nF cap
good luck!

mine was 7.xx bur real version was 4.01 and antenna did not work i just removed the caps and did not fit any other caps just swaped out the resistor and woopy now antenna is working , first test was with toyota key and second test was with benz sprinter all good

try in id 48can vw.you can read CS?

Hello there,
My antena is from an golf IV with resitance 23ohm

Here are the mods i did:
1. replaced 150k with 15k (resistor)
2+3+4 here we need to solder a capacitor with aproximately 6-7 nF(put one or combine from 2-3 capacitors)
5. removed 100 nF capacitor
6. removed 100 pF capacitor
in position 2 it was a 2.8nF capacitor
in pos 3 it was 0.5 nF cap

in pos 4 it was 100 nF cap

Hi guis i am new in the world of Dk and want to tell hi to all from Bulgaria, a want to know if someone test the solution posted from WIPPO69 it works or not,i have the carprog 8,21 clone and make me the same error when want to read some key? thanks in advance to all

try in id 48can vw.you can read CS?

the only and only reason i got carprog is for opel ecu pin read , the other stuff is just aded bonus but on vag id 48 can i did
not try that , for vag i use other tools but good question i will try and see thanx m8

[electronistul21]

you can use carprog for read and write CS to transponder ID48, preparing key for adding to car.

Hello,
I have another problem. The error message is "Transponder signal to low". Does anybody know where is the problem please?

thank you
Ladislav

This solution works for me. I tested on 48 with Audi A4 B5 99r. I am sending a photo as I solved it on my Carprog. My antena have 3ohm.


The only problem I see is that the antenna has a problem with catching the transponder. You have to make many attempts before setting the position of the key in the right way. Another time, the message pops up like in Ladis1510.


I will try to make antena from the Audi ori solution (from car).


I will share if it works better than the clone Carprog antena.

If anyone has a problem with the antenna, there is a detailed description with a photo of how to solve it.
