Hello people, here's where I am right now : I have a 2002 A4 B6 - originally from Germany ( so European version ). I bought it used from someone I know very well , the car was great, the only issue - it had one key. I have been ok for the past years but decided to have another one just in case I loose the first one. The dealer asked for 150-200$ for a new one so I decided to go down the DIY way
I have bought a complete key off ebay, with a blank blade ( which I need to get cut ) and also a virgin ID48 chip to have it programmed to my car's IMMO. The key already has one but some people say you need to have a VIRGIN one and so I got that as well.
The remote part is easy to get done so I will get straight to the immo part. I know that the "new" key can be programmed to the car's IMMO with either VAG Tacho/Commander interfcaes ( depending on car year/model - these are also the interfaces that READ the immo's info )
or if I already have the SKC - via a simple VAGCOM interface that a lot of people use/have. The SKC code was not given to me by the previous owner as he didn't have it either so I went on and found someone with a Vag Commander in order to have it read off my car's IMMO. He managed to connect to my IMMO and read out a 5 digit LOGIN code and told me that's the one I will need to program my new key. He also said that the key can be added right there but I didn't have it with me ... so now I have this 5 digit code that I will attempt to use with a VAG COM interface.
My question to you is : why is this a 5 digit code and not a 7 digit code? Could it have something to do with the fact that my car is a 2002 model ? And also, according to Ross-Tech, I will have to input "Date on which the PIN was generated by the dealer" and a WSC Code. Can just input anything on those fields or it has to be something SPECIFIC - and if so, where do I get it as I don't have anything except this 5 digit code ?
LE: it appears that having a 5 digit code is better than the 7 digit one. The 7 digit one appears to be actually the same thing with the 5 digit one, only encrypted, plus you need to input the other info. The 7 digit one is the one you would have on a piece of paper from AUDI and if you don't have it ( like most of the people don't ) there is no way of ever seeing it. It's only suitable if you can't get the 4/5 one. Best way to do it, like I did is read out the 5 digit one ( if it's a 4 digit, just input a 0 in front of it ) using a Tacho/Commander and have it entered, either on the Tacho/Commander screen when you try to match new keys, or on the VAGCOM. This code is everything you need.
Will keep you posted on the progress once I have my blade cut, most likely in the next 2-3 days.
