I think the E53 can smell money... (Codes abound)

[270_BMW]

So minus the transfer case scare back last week which doesn't seem to have come from anywhere, got it up in the air and could not spot a leak or trace of oil/ATF, must have been from the Wife's CRV which has been parked and moved around occasionally due to being on it's last leg. Thank goodness.

Moving forward getting all the bills paid I get a phone call that the X5 has died several times and is rumbling like a rodeo while picking the kids up from school...
Get the computer hooked up to it... (Just an OBD reader, not INPA mainly because I don't know where to buy it) and I have codes galore.

What do you guys think?

After clearing the codes out, staring the vehicle it's still misfiring sounds like I am listening to some bass heavy rap on the inside,
