hey everyone looking for some guidance. Just got a new to me 2014 z1 with the L96 6.0. Took it out for the first time and had to be towed back. Boat lost all power and felt as if it was running on 4 cylinders. Took back to the dealer and they told me they couldn’t find anything wrong and no codes came up when they scanned it. I insisted they lake test it and that something had to be wrong. After they lake tested it they told me they got an Audible alarm but nothing on the dash. They hooked up the scan tool and told me the alarm that went off was just to say the check engine bulb is burnt out....doesn’t seem right to me. Has anyone ever heard of such a thing ?
