I changed more or less all modules on my previous mk4 with used ones from the scrappys and did not need coding or nothing.. just a b1tch to change em 
Cheers mate.so defo doesnt need coding then.
Dont no what to do then as ive fitted a replacement from a sxrappy and im having exactly the same problems.key doesnt unlock car from push button,no door olen sign when drivers doors open&no warning sound when lighys are left on and no puddle light.
I dont no If my door module i have just fitted is also faulty or weather it could be the CCM.
Surely if the new door module was faulty it wouldnt be the exact same fault as the one i took out??isnt there a few diff microswitches that could need soldering so the one ive just fitted could of had different syptoms??
God no's im confused.
