Did you checked the engine timing? And its normal for an engine to choke when you push that dipstick again after pulling it. When you pull it, the gases escape through blow by.

 

Are you sure the ticking isn't just the fuel injectors? FSI engines do sound "diesel-y."

 

The fluctuating RPM at idle make it sound like bad PCV valve...

 

Check with the dealer to see if your car is part of the service action that was started recently. Audi will replace the PCV valve and related plumming free of charge.

 

I have the same ticking noise on my 08 A4 Quattro. OP, did you figure out what the cause is? Thanks,
