Has anyone done any of the following recalls CODE 422 M3 S54 Connecting R, CODE 399 M3 SMG RELAY, & CODE 423 SMG REPROGRAM. If so, what are the disadvantages & advantages? Any increase/decrease in performance? Any info would be appreciated. Jennifer.

HAVE THEM ALL DONE! There are no increase/decrease what so ever in performance, but the car should have all these Service Bulletins done. I have had all of them done over a year ago and no problems to report. All these will be covered under warrantee and you will get 100,000 mile extended warrantee on the engine due to the rod barring fix.

I HIGHLY SUGGEST YOU HAVE THESE DONE!!!
