Hello, I tried the KKL interface with my 2003 225C TT, it worked well with the VAG-COM 4.09 software.

I tried to update the car database but was unable to do so. Can someone else try to update the database as it incorrectly says that it does not work with the TT.

I tried with the L line disconnected and it worked in that mode also.

You can't update anything there. Just add a new entry, please.

I tried but it didn't work, perhaps its because I am using the bablefish translator, it gives me problems loging into the forum and loging into the shop.

Try it without babelfish
