hi I have a 2005 bmw525i it was running fine the night before,parked it and started the folliowng morning,it back fired 3 times, so lou.d that the nieghbors thought there was a explosion.......
now it starts,runs rough,and sounds like a popcorn maker in the rear 2 or 3 cylinders,the check ebgine light is on, but my snap-on solus scanner has no communication with the car,all the fuses in the trunk and glove box area are hot...i'm sure I could find the problem easier if I knew what the check engine light discloses but what to do.. Has anybody heard of this crazy problem.

It might be the cyclone separator has failed. OBDII communication is not always possible with generic scanning equipment. The part# for the separator is 11-61-7-501-566 and can be seen in exploded view @ Realoem.com ♥
