    My 4 year old E320 is slow to start, especially on a cold morning.
    After it does start the preglow indicator then comes back on and stays lit until the engine warms up. Once the engine is warm the car starts with no problem.

    What's the issue here?

    The pre glow light coming back on indicates either 1 or more glow plugs have failed or there is an issue with the glow plug relay.
