Well the title sort of says it all. I have a ’07. 5 CC that I attempted to start today and it won’t turn over. It makes sort of a “thunka thunka” sound when I attempt to start it. It’s not like a loose battery “buzzing” sound, it is much slower and sounds like the engine is stuck or something. It has not been started for several weeks but the batteries are up. Anyone have any ideas? Oh, and it is all stock and only 10K miles.
