What causes the DRL warning light to come on in a VW Passat 2007?
It is not a warning light. The DRL stands for Daytime Running Lights and will always be on unless you turn on your dashboard lights.
All your warning lights click on and off when you turn on the ignition switch?
If you are wondering why this happens, it is completely normal. When you turn your key all the way to start the car, all the warning lights will come on do perform a lamp test. Also, the computer runs a quick test on all the sensors in the car and on all the lights on the dash to make sure everything is operating properly, once you start the car, these lights should all go out. If there are lights remaining lit on your dash, it may mean that your car needs to be serviced, always get warning lights checked if they come on while the car is running. Hope this helps!

Why do the engine warning lights come on when the car is off?
By "OFF," I have to assume that your question means that the ignition switch is "ON", but the engine is not running. IF that is what your question means, then the reason the engine warning lights turning on is that the manufacturer designed the system that way to show you that those warning circuits and lights are working, and ready to warn you after you start the engine, should there be a failure in one of the systems they represent.
