Isn't there a function to do this via vag com?
-connect to module 35
-click on soft
coding
-take note of the number you find so that, in case, you can put everything back in order.
-convert the number you find from decimal to binary digits [windows calc can do it]
-starting from the right, first bit being number 0, the 0s and 1s mean if a specific function is off or on:
-bit2: one touch [all doors lock/unlock together. if on 1 the opening is differentiated]
-bit5: doors lock after 15km/h is reached [only mk4 i guess]
-bit6: windows up when remote lock is pressed
-bit10: horn chirp when alarm is put on/off
don't touch the other bits.
Now re-convert the number back in decimal base, press 07 - Recode and insert the new value. Press Do it! to save.
Now
problem is that I'm not able to connect to module 35. Some say it's module 46, I don't know. But I know I'm not able to connect neither to module 46.
The autoscan function for the mk3 scans for module 35 and not for 46.
I don't know if it's my equipment that makes this connection not possible. But before installing something, I'd try this if I were you.
