I bought it one month old from a Norwegian supplier, it has been used on a 2006 Bmw 630ia. So that they just deliver for the E90 can't be thrue. Other than the software, what can be the difference?
Its odd they don't list the ess kit for an si 3.0,but use a kit on a similar engines 5series.....whrn i asked years ago for my2005 3.0i,was told the kit couldn't be used on an si,so must be some changes in the kit. Nice one
