E39 540i ecu not being detected

I just purchased a 2002 540i6 msport. Everything is clean and nice but there is a misfire. Normally just like all the other cars I have owned I would connect my snappy computer and read the codes. When I tried this though the computer wouldn't/couldn't read my ecu. It would do everything else such as clearing airbag codes or reading the transmission. I am not sure if this may be something easy and simple to fix or if I need to get someone to look at it. The previous owner had subwoofers wired in the back where he tapped wires and all kinds of jigaboo nonsense which I am wondering if it could be related. Any input is greatly appreciated, I am really looking forward to driving this beast! Thanks.
