Small correction tasks with the Lexus.
"Upgraded" the navigation data DVD from the original data
Version 1.0 to the latest data (for the Gen 2/3 systems)
Version 13.1. Did this just because.
The interior car has always had this oily, grease-like smell. I could even smell it in the trunk.
I thought it was from pre-sale detailing products or

. After I finished with the navigation (~15 minutes), I went into "Simba the Wonder Dog" mode and put my sniffer to work. The smell wasn't coming from the leather, carpet/mats or any other surfaces. Then I went for the cabin filter. There it was. I don't know if these things are oiled, but this thing reeked.
Running the AC, it cleared pretty quick. I'm hoping it isn't refrigerant oil I'm smelling. We'll see.
I had a replacement Denso filter on the shelf.
