Dropped a LUG-NUT in the Engine-Bay compartment
Replacing the stock air-filters with aftermarket highflow WIESETECH airfilters. Was almost done with the job and I dropped a lug-nut (I think its metallic) in the enginebay. The drop was follwed buy a dull thud. Looked under the car and it did not fall through. I am sure, the car is undrivable now, because at some point with the high speeds and brakes, it will hit the radiator fan and BOOM!
So, I need solutions?
1) Jack the car and try to undo the panels under the engine compartment?
2) Also, not even sure where to jack the car?
HELP!
Harbor Freight should have these 2 items. Good luck.
1- Its probably not safe to startthe car or drive, right!
2- Was thinking to jack up the car and open the bottom panels,
I can't find any links or pictues that shows a 2016 AMG GTS models, undercarriage or covers.. wanted to get an idea where to jack and what to open.
The lug nut is most likely on the right side of the car, in the hood area.

like MBNRG mentioned...the magnet tool should help. Otherwise, just keep removing trim pieces until you find. If you're like me, you probably will.
Else, consider it went to a better place to chill. Probably went on to some new friends.
One thing though...if you start jacking, it may roll to a different location. Then it may never be found. Up to you.

most likely the biggest risk of driving it is losing the bolt.
here are a couple of recent pics of my front bumper removed so I could install the protective screens on the radiators. Hopefully this helps show what things look like. If you take off the front bumper, you should be able to tilt down the center cover and see back behind the radiators area. I dropped a screw back there and had to use a telescopic magnet pen to snag it.
front bumper is 7-8 plastic clips in each wheel well (recommended taking off the wheels), two screws in wheel well towards front that connect bumper to fender (pain in the A to get to), x6 10mm bolts across the bottom underside, x4 T25 torx across upper bumper and x2 T25 at each corner next to each headlight.
coincidentally, when I got my front bumper off, I found 2-3 plastic clips that were dropped behind there during assembly- so even though he guys at the factory have this problem! Hope some of the pics/info help and good luck!
Under the radiator you can see the cover panel. Radiators have plastic surrounds so very doubtful it fell in there, if it did you could see looking through bumper openings
Center radiator layout without bumper, you can see lower panel that should tilt down to see back into the area by the engine
Center area you can see the cover panel that tucks into bumper

NOT "NUT/BOLT RELATED" but similar:
A coworker and I were working on a panel forward of the windscreen, when he bumped the spray bottle of isopropyl alcohol off the top of the nose of the aircraft. Before I could grab it, it hit the floor, breaking the adjustable nozzle in two, the bigger half stayed with the bottle and the other half "disappeared." We searched for 2 hours, the entire hangar floor, grounding points, swept the floor, etc. 2 hours after we filled out the "Lost Tool Report," it was located......on top of the left wing, sitting dead center in the wing, 35' away from the impact point and 8' off the ground.
A lighted magnet on a 24" flex extension if the drop is iron (HF purchase if I remember)
And
A bore scope on a 1m flex extension (as Raven mentions).
Before I start disassembling anything, these two tools will work 90% of the time.
I bought a cheap endoscope from Amazon to find a bolt before. It has a clip on with a magnet - which was fantastic. Everyone should have one of those tools for how useful and cheap they are
