I bought this off a forum member for my E63. It turns out that when his mechanic removed it from his W211 E55 they just cut it out and did not unpin the harness. Programa was absolutely zero help in getting a new connector (their response was "oh well, too bad") and the guy I bought it from couldn't be bothered to remove it from his car and send it to me (he claimed he had his mechanic pull it). My mechanic looked into it and this ELM will work fine if you want to hardware it into your car. Neither myself nor my mechanic were comfortable cutting up the stock harness so I opted to not install it. The previous owner said it worked as it should when it was removed from his car after installing coilovers.
I am selling this as-is. If you get it and it doesn't work, that's not my problem. I haven't tried powering it on so I'm just going off the word that it works from the guy I bought it from.
$100 shipped in the US. $100 + actual shipping for anyone outside of the US.
