Hi folks, New here so hoping to help out with problem solving and maybe find some help with current technical challenges.

My 55 plate Polo SE was bought without the remote key working, open and close manually with key in drivers door, I assumed an easy fix with re-synchroning the key. Problem is that although I can re-synch the key with VCDS it appears to only work for a short period, 10mins! then reverts to no response from the central locking.

Working through the posts on this common VAG issue I have replaced the batteries in the remotes and followed the re-synch method as per Ross-Tech method. Reading a post here on the Audi forum I think the Central convenience control unit has become ‘deaf’ to the remotes so next step is to replace this. Hope this will restore the remote key function so that the alarm doesn’t sound every time the engine is started, v annoying!
