Dunno the proper name but me or Djw Dave should have one knocking about, hopefully we didnt leave it in the shell, cover the postage and its yours mate
I've changed one before, no programming required when I changed mine.
Make sure it's centred while fitting it (indicator window shows this) and it should be ok. You might get some TC/ABS lights but they disappear after a short drive ime.
Aw hiya.
BTW, mines doesn't have that white wire coming out for the airbag(like that ebay link). Has it been chopped or is part of something else on the 182?
