5th Series engine misbehaving...

Fellow I know is chasing a "loading up, then backfiring when the car warms up" situation on his 526/533. I suggested possibly a coil issue, which has now been remedied, to no avail. I vaguely recall a recent string on misfiring/backfiring issues which is where my coil suggestion came from.
As most of you know, I ain't no mechanic - but know where to go for advice/suggestions to pass along, so please, friends, don't let me down...HELP!
