E46 (318Ci N42, 318Ci N46, 320Cd, 320Ci, 323Ci, 325Ci, 330Cd, 330Ci, M3). You don't need to follow the first 4 digits of the BMW part code because they only show the head and subcategory. THE LAST 7 SYMBOLS OR NUMBERS OF THE PART CODE ARE IMPORTANT.
This used part fixed my roof problem on my BMW e46. The hood would not open, the boot lid would tilt back open, but the hood would not fold down. There is 2 lock catchs on each side of the rear seats. When plugged into laptop the catch all ways came up with a closed signal. So was faulty.
Very happy with the used part, and seller.
