[empower-auto]

I noticed this last night .. after normal driving I pulled into a drive-thru and I could hear a lot of ticks and switching sounds under the hood - very presumably the D4S system.

It sounded very finicky like the D4S couldn't decide what it was doing and something kept switching on/off or back and forth and the revs would slightly alter each time. Not significant but it was definitely weird.

Anyone with similar experience? Performance wise nothing seemed out of place.
