Door lock pulse extender

Hi, My keyless entry kit supplies a door lock pulse of 3 seconds to control a vacuum CDL on a 1997 Audi A4. What I would like to do is extend that negative pulse to 30 seconds to simulate the comfort closure feature of holding the key in the door lock position to close any open windows. Could anyone advise on how this could be done. Unfortunately here in the UK we don't really have any trick DEI modules like the 528T etc. Thanks

could use a relys and a capacaitor and such but waht values to use im not sure. can try ebay i belive soem with ship over there. dont DEI dealers can get stuff liek the 528T.

Find an Audiovox dealer and get a AS-9632 timer module. It is designed for this purpose. sparky
