Car does not turn over while on a slope on 2003 Volkswagen Passat

The abs and engine lights are always on. When I park in drive-way with a little slope downward it will try to kick over but doesn't. This happens occasionally. Battery is new, plugs new, plug wires new, plenty of high octane gas. If I let it rest for 3-5 minutes while the engine is still cold it will then turn over. When parked in the garage or at work on level ground it kicks over every time. I have 237,000 on it...

Try this, next time you park on a grade and before shifting to park, set parking brake then shift to park. Start car before releasing park brake. Post results. May have an idea.
