Presumably an E9x is similar...
If it is was a critter, adding the critter zapper (unfortunately not allowed in the US) would be cheaper than dealing with the carcass afterwards. Here's the E46 version. Apparently there is enough of a problem with critters eating the wiring that BMW has come up with this kit as an option for all of Europe. |
That cover pic is pretty awesome.
