Hello
Ive read alot but request someone tell me the order in which I should go about a solution for my problem.

I have a 2004 Audi A6 C5 1.9tdi and Ive lost the key! The car is currently accessible with a spare flip key I bought and I got a blade cut so no problem unlocking doors, but the alarm is activated and the key wont start the car because its never been programmed for this car.

So am I right I need to retrieve the secret code from the ecu in order to program the key to the immobilizer but I cant get that code because the immobilizer is activated which blocks retrieval via obd2? So I have to take the ecu off the car and get the file which has the code, turn the immo off in that file 95040.bin then put the ecu back on the car and then go through the key programming procedure?

Many thanks for any help provided!

Read cluster dump , get pincode and adapt immobilizer

1.9tdi is a edc15 so no 95040 eeprom ;)

ahh thx for that, that would explain why i get error 0x00

so i need to read the instrument cluster for the pin. i only have a ebay blue kkl cable ch340 usb, and a bluetooth obd2 adaptor (which ive not tried yet)

the blue cable works with vcds lite, or do i need to use some other program? sorry but like i said im REAL noob lol. i would pay someone to do this but the audi dealer here in rural hungary wont give me an appointment for 2 weeks lol and god knows how much that will cost!

thanks!

Hi, using VAG EEPROM Programmer and blue kkl. It's very simple, everything is done within 5 minutes This is only for vdo. Tell me what is your panel vdo or magnetti

thanks for the help. i got that eeprom 1.19g i set the port to port 2 which is same as my blue cable but it gives error no ecu found. I can only get vcds lite to work it uses kw1281 protocol or something like that. I will post a pic of the details it comes up with on that program. thx

I read VDO - FTDI and ch340 cable no problem. With magneti marelli more difficult

well i dunno why it wont work for me, it seems i have VDO. is there some other software i can try. i tried vag commander, wont connect either

this is all i have

Won't be doing much with that

marti, why? everything is very simple with these panels

I guess its the ch340 chip problem - i have good quality blue kkl based on ftdi 232rl and have no problems ( i bought it in Poland from a local business called viaken , costed about 7$ )

Because FTDI is just as inexpensive and works with more things.

I also have the original galletto and vag chips, the ch340 has its advantages, there is no third-party k-line converter and driver problems. I think that the problem in the software and not in the gland

I read somewhere windows 10 is not good for this so Ill try get a windows 7 pc. Failing that Ill try buy another cable. Thanks for all your input, at least I know a bit more than before lol

woohoo success! i installed windows 7 and it connected with eeprom programmer 1.19g

i selected read eprom on the dash tab and saved the bin file, now what do i do lol, ok i guess i have to read more lol. i did see some info about login on that program with a code of 1701 so i opened vcds lite and tried to use that code to login to the immo module and i put a 0 in front of it but it said not accepted turn off ignition for a while and try again so i guess thats not the code i need?

also getting ahead of myself here but once i work the code out what if my second hand key fob wont reprogram? how do i take the immo off completely

many thanks!

Congratulations, I really have Windows 7 installed. Try using the full version of VAG-COM

ok i tried with full version, same thing. i tried with the immo module that gave error, with the engine module it didnt give error. sorry i dunno what im doing

You have to open 17 instruments not  immo

thank you

you got the wrong way you need a Dashboard in it immo
1. Go to Block 17 of the Toolbar.
2. Enter the pulled out PIN in the Input column (5-digit, non-terminating digits in front fill 0.)
3. Select the column Adaptation
4. We enter 21 channel
5. In this channel, enter the number of prescribed keys (from 1 to 4) if you need 3 keys, then we write 00003 - or 2 - 00002, etc.
6. Click Test, Save and Exit
The IMMO lamp blinks and goes out, remove the first key and insert another, turn on the ignition. IMMO lamp lights up, blinks and goes out. We take out the key.
Everything, keys are registered in IMMO.

ok did 17 instruments but wont accept key, any way i can turn the immobilizer off completely or thats too difficult for a noob?

You have new immo capsules in your key?

i dunno probably not bought they second hand key off ebay, cant wait for a new capsule im in the middle of nowhere. thanks for your patience

I doubt that you will succeed with your cables.

You cant use capsules that were adopted to other car - you need new ones

ok bought new id48 capsule and finally it accepted it and it works!

Thank you for all your help, life saver!
