Looking for some advice on upgrading my key. I currently have the single key with no remote. I would like to have the flip style with the 2 button remote. I Read the link below (thanks Tom) http://www.vwaudiforum.co.uk/forum/showthread.php?7457-B5-A4-Central-Locking-FAQ/page3 This helped explain what central locking unit I had and what unit I need. "8L0 862 257 early model remote c/l pump, has limited functions e.g wont operate door pin led's or flash indicators on unlock 8L0 862 257 'A' early model non remote 8L0 862 257 'H' 98-99 non remote pump 8L0 862 257 'G' 98-99 remote c/l pump uses 2 button remote fob 8L0 862 257 'P' 99+ facelift model pump, all facelift have remote c/l and so behaves oddly if you use the key to open door (drivers door only will unlock untill you turn ign. on) they also use a different siren (batt back up type) so arent compatable with earlier cars" I had a look and found that my CLM was 8L0 862 257 H which is the non remote. According to the above I need the 8L0 862 257 G module. Now i Managed to find one and tried to connect it today. Located in the rear quarter I disconnected the Two air line pipes and 3 electrical plugs Thought I'd try and swap the units over to see what would happen. The module works! Unfortunately that was it. I could hear the pump going, pin locks going up and down, alarm goes mental and the front windows drop down. Keys and remotes had no effect. Only way to stop the alarm was to disconnect the "G" module. I read that I may need to soft code this new module in using vagcom. (Complete amateur at vcds) I didn't know if there was a correct procedure to change this over without the alarm going constantly?? Hopefully once this is installed I can look into remote keys!
