US/LHD BMW E46 Sedan and Coupe Factory Rear-Seat and Through-Loading Identification
US/LHD 1999-2006 BMW E46 Sedan and Coupe factory rear-seat cushion/backrest donors only, narrowed to fixed versus S465A through-loading equipment. Prove both VINs/builds, Sedan versus Coupe, production, fixed versus split/folding configuration, left/right backrest sections, upholstery code/color, headrests/armrest, catches/strikers, belt/buckle/interface and written contents. Exclude Touring, Convertible, Compact, E36/E9x, M3 Convertible assumptions, non-US/RHD claims, restraint bypasses and bent, torn, crash-loaded or contaminated donors.
WHERE TO BUY
Open an exact listing, then confirm fitment, stock, price, and shipping with the seller before ordering.
Seller links checked . Prices and availability can change.
Begin with both VINs/builds, US/LHD Sedan or Coupe, production, S465A through-loading state and upholstery code/color. Photograph all labels, cushion underside and frame, both backrest sections, hinge/pivot and catch geometry, headrests, armrest/pass-through, belt slots, buckles/connectors and mounting hardware. Require a written inventory of cushion, backrest section(s), frames, upholstery, foam, headrests, armrest, catches/strikers, buckles and hardware. Reject bent or welded frames, damaged catches, torn or collapsed foam, broken mounts, crash-loaded or missing restraints, cut wiring, serious rust, fire/flood/mold/pest/smoke/biohazard contamination, hidden repair or unavailable actual photos. Use current BMW seat, belt and mounting procedures with qualified inspection; no cross-body conversion or restraint bypass.
OEM numbers
REPRESENTATIVE CHECKED FRAME IDENTITIES, NOT ONE E46 REAR SEAT. S465A through-loading backrest frames include 52208225745 left and 52208225746 rightchecked catches are 52208209035 left and 52208209036 right. A checked Coupe base/frame example is 52208099643 in its exact equipment branch. Upholstery and cushion assemblies vary by body, production, material/color and equipment and must be VIN/catalog matched. Convertible and Touring rear-seat geometry is separate and excluded.Supersession
The checked evidence establishes body/equipment branches, not a universal supersession. S465A left/right frames and catches remain paired by side; 52208099643 is a checked Coupe example, not proof of Sedan/Coupe or fixed/folding interchange. Shared upholstery descriptions or attachment hardware do not override body geometry or option code.
Fitment
Begin with both VINs/builds, US/LHD Sedan or Coupe, production, S465A through-loading state and upholstery code/color. Photograph all labels, cushion underside and frame, both backrest sections, hinge/pivot and catch geometry, headrests, armrest/pass-through, belt slots, buckles/connectors and mounting hardware. Require a written inventory of cushion, backrest section(s), frames, upholstery, foam, headrests, armrest, catches/strikers, buckles and hardware. Reject bent or welded frames, damaged catches, torn or collapsed foam, broken mounts, crash-loaded or missing restraints, cut wiring, serious rust, fire/flood/mold/pest/smoke/biohazard contamination, hidden repair or unavailable actual photos. Use current BMW seat, belt and mounting procedures with qualified inspection; no cross-body conversion or restraint bypass.
Aftermarket options
Exact-frame upholstery or foam repair can be compared only when Sedan/Coupe, fixed/S465A, section, trim and restraint interfaces are proven. Touring, Convertible and M3 Convertible pads, universal covers, seat-delete panels and modified hinges/catches are outside this factory donor-identification claim.
Before you buy
Match both VINs/builds, Sedan versus Coupe, fixed versus S465A through-loading equipment, side/section, upholstery, catch geometry, actual photos and written contents. Touring and Convertible rear seats are excluded even when a seller calls them E46.
