The dealer found a small part in the oil pan and they cannot figure out where in the engine it could be from. It is a very thin circular metal part with slots where possibly a gear could fit. Images attached.

It's a roller bearing cage (holds the rollers in place). I don't know enough about the internals of the S62 engine, but I would suspect an internal roller bearing is going to fail as the rollers wear against each other, or fall out of the bearing races.

What is the official OEM name of the 'roller'? OEM part search doesn't pull up any results for roller or bearing cage.
EDIT: Could this be from the flywheel, clutch or slave cylinder? I recently had a clutch burn out and those 3 items were replaced. The oil changed happened just now when they found this part in the oil pan.

NO. See below.

NO. No roller bearing in those parts.
It's part of a ROLLER BEARING. There are an inner race, and outer race, about 20 or so rollers (ball or conical rollers, that sit in the races), and a cage that holds them in place. The square holes you see are to hold conical rollers in place.
I am only guessing ... but, I would guess it is part of the camshaft mounting. Or the bearings on which the gears for the timing chain ride. Could also be from oil pump bearings.
I would have to study an "exploded" engine drawing to be more precise.

Whatever it is, I would suggest not driving the car until this is figured out, else you suffer some catastrophic failure. Roller bearing cage seems most likely as pointed out above, but I have no idea where you'd find roller bearings in this engine. (BTW, most digital cameras have a close-focusing "macro" mode, which will give you a much sharper picture than you have here.)

"Is it the sounds that make a BMW a BMW? A BMW is designed to be heard, felt, experienced. So our engines sing. Our steering talks back. And we insist on offering manual transmissions in nearly all our models for drivers who crave them. The result is an almost telepathic oneness with the car. Just as surely as you can hear a BMW, a BMW hears you."

Based on my personal experience, here is what I suspect happened.
Someone used an oil pan to drain a broken diff or tranny. Broken bearing cage fell out. Since there is so little oil in either, they didn't drain it before draining your engine into the same "mess." Walla ... they think it came out of your engine. Or (also a possibility) someone threw a broken bearing cage in there (closest place to throw it, and I've seen stuff thrown into oil drain pans in the shop, often).
Problem is, YOU just don't know for sure of where it came from.
I would request a meeting the the BMW factory rep (will be difficult to get, so you must PUSH!). Ask him where it could have come from in your engine.
I know this is an old thread, but thought the above might clarify what could have happened.
