This is different. It isin't coming from the track but maybe from the switch or a relay under the seat. It sounded like when you slide the button to move your seat and it first clicks on, then when you let it go it clicks off. That's the sound it makes, only no one was sliding the button and it was just clicking twice, pausing, then clicking twice. It was definately an electrical noise, not mechanical. I've been listening for it but it has only happened twice out of 10 or 15 entry and exits.
