Hi
Have you checked your fuses ?
Nick

Are you planning on installing an after market radio ? If so, recommend you use an empty slot from the fuse panel to run power to your radio. This will help to avoid having other system components being affected by the new radio. If car still under warranty, it will not void it.

I have the same whistle sound, too.. since last year... just after warranty period. I've notice it comes from the clutch of the compressor that helps the engine until 3000 rpm when the turbo goes into the action. to replicate the sound, check left side of the engine, put someone to push the clutch pedal and then press on the accelerator. Check with VW if there is a solution, although I think you will run thousands of miles and no damage because of that.
