335I Engine Malfunction

One of the reasons I joined this forum is to see if anyone else has experiended a similar problem I'm having with my 335I Coupe. I'm currently living in Germany and purchased my American spec 335I Coupe in Nov and have approx 4100 miles on it. While crusing at approx 80 MPH in 6 gear my car started to run rough, acting as if a spark plug was misfiring or water was in the gas tank. Eventually an engine fault indication appeared on my display and the words power reduced service engine also appeared. I took it to my local dealer and was informed there was a recall and I needed new software. The software was loaded and the probelm remained. I took it to a different dealer and they hooked it up to their computer and found nothing wrong. I will take it for a thrid time because I'm still having the problem. When driving agressively and shifting throught the gears at high RPMs I don't experience the problem only at crusing speed and lower RPMs. Has anyone else had this problem?
