I didn't know the check engine light came on when it detected a firmware update? The last two had to do with the DEF. They can also annoyingly come on and cause lots of panic even though nothing is really wrong or if the problem is quite. Your gas cap is loose, causing your "Check Engine" light to come on. A flashing check engine light is typically indicative of a serious problem affecting your vehicle's ignition, fuel or emission systems. In some cases you need to pull over immediately to prevent damage while in others you merely need to tighten you gas cap next time you stop in order to reset the service engine soon light. The owner said that everything is fine. Brought it into VW dealer and they told me it’s a cam and crankshaft sensor problem. Usually these sound more like a whistle, but may sound like a whine if they are large enough and could also cause the engine to die at idle. It's just a light with no information telling you what the problem is.
