Hi all! I've had my Giulietta in for a diagnostic check as my engine management light keeps coming on and doesn't let me use any DNA function or start and stop. Also it really struggles power wise, shakes and coughs and splutters. Please could someone give me any advise on what the problem could be or if someone has had the same problem? The error code came up as 1064h/4196 if anyone knows what that could be? Thanks all!!
