Amazingly enough, If one or more of your brake lights is burned out this can cause the Glow plug indicator to flash, replace the burned out bulb(s). This often sets a Code but will not turn on the Check Engine light. It took me forever to find this solution first time it happened. I've seen it many times since.

Check your brake lights and brake light switch. These brake light switches are a common problem with vw's. They can become intermittent and can also fail off or on. A revised switch is availible from Vw if this has failed on your car., Good luck

Sounds like it is telling you that you need to get a glow plug replaced that is not functioning properly. Have a reputable shop let you know which one it is.
