Golf Mk4 1.8T GTi Central Locking
Looking for some expert help. The Mrs 1.8T GTi 3 Door central locking does not work properly. The key fob buttons are knackered anyway, but it still does not worjk from the key in the door.
Well I say it does not work - it unlocks both doors fine, from both doors, as advertised. However when locking, it only locks the door the key is in, so it does not central lock!
I suspected the Convenience Control Unit - bought one and fitted it - the same fault.
I have also downloaded the VAG COM software, and bought a cable on ebay, but it fails to connect properly. So I have not proved its a coding issue.
Any help would be appreciated as the Mrs is getting narky about this! Apparently it is my fault!
Thanks in advance
