Finally I seem to have ended up in just the right place

Greeting everyone!
Ive had a read through a few of the posts here but although the Topics are all related to my issues I dont quite seem to be able to find the answers Im looking for. I have an Audi A3 1.6 (2-door) - I believe its the 8L.
There are a few issues that I need to take care of, mainly electrical but Ive been asked to try to find the engine login code because a previous owner had made changes and I just want everything set back to factory standard. I dont have a cable or the VCDS software, a friend of mine has a Geniune cable and I believe the latest version of the VCDS software and given that I have NO idea what Im doing - he is going to reset everything back to default for me.
So, with this info in mind is there anyone here who can help me to obtain the correct engine login code for my car?
Any assistance is greatly appreciated.
