Hi, hope someone could help me, I think I have a problem with my ignition coil on a 325i auto convertible which is situated near the battery and washer reservoir, is the coil used on 316i, 318i, 320i, the same as 325i? they look the same? I cant get hold of a 325i coil but plenty of 315, 318, 320's
