Have had my Cobb now for almost 2 weeks on a stock 2009 335i 6MT. I love the increase power/performance. On initial setup got the "Unrecognized ROM" reading, emailed to Cobb and they incorporated the new Rom in 2 days! About a week ago a warning signal appeared in upper window "Bulb of exterior lighting system failed" along with the "Service Due" triangle with exclamation point inside the bottom window in the upper right hand corner. Checked all exterior lights and all were working properly. The following day they both disappeared and reappeared again yesterday. Has anyone else experienced this and should I be concerned?

Also, never really push the car to it's limits until a 2011 Jaguar XK challenged me. I'm not a Jaguar advocate but damn what a nice looking car. I was dead on his ass the whole time and I mean on his ass. But never got the opportunity to try to pass because of traffic. In retrospect, didn't really know the car pushed with that much speed until I really push hard on the pedals. Oh... and I did get a minuet smell of smoke after that run. Is that normal as well?

My car is 100% stock and I've gotten that exterior lighting system failed icon twice in the year I've had it. I still don't know why. Both times it disappeared within a day so I couldn't get it to a dealer.

There's a Service Bulletin about this. The bulb socket needs to be replaced. Pretty common problem on early E92s.
