My 09 e90 335d has two fuses for homelink. When I tried the first one with the tap with the tap, I could hear my alarm (I am installing a car alarm not a radar detector) click immediately, and the car was off, so I knew that was wrong. The second one I got no response from, so it should be the switched ignition wire (however the tap fit in very lightly so It could be a bad connection, I guess I will find out). Otherwise, if you have two fuses for your homelink like I do, use a DMM on the each until you find the one that has no power when the engine is off. I guess the homelink needs constant power and power when ignition is on, strange because it only works when ignition is on. But I cant think of any other reason for two fuses.

If your homelink is stopping working while the engine is on, maybe you have a bad tap -- it is sending the engine on signal down the RD line and not the homelink line.
