2001 octavia 1.9tdi cambelt whine?

Hi there,

I've recently had the cambelt and water pump changed on my skoda octavia 1.9tdi 110, and ever since i picked the car up there is a reasonably loud whining noise coming from the engine bay. This is particularly noticeable when letting the engine drop back to idle after revving it in neutral (not so noticeable when in gear). I am a bit worried that the cambelt might be too tight - is this possible on this engine? Or is the cambelt self tensioning?
The garage also did not replace the engine tray when putting it back together, as it was too damaged to refit. So, the only other possibility i can think of for the source of the whining noise is that maybe it is coming from the ancillary belt, and i just didn't notice it before because the engine tray was doing a good job of sound proofing the engine.
Am i just being paranoid?
Does anyone have any thoughts on this?

It should use the same TDI tensioners as the VWs. They're all self tensioning if you set it correctly with the arrow in the middle. If you turn the engine using the crankshaft 12 pt bolt to TDC, and on a cold engine, the arrow should be in the window. And it could of course, be wind noise or other noise. Check out this writeup to see what the tensioner should look like: http://www.myturbodiesel.com/1000q/a4/ALH-engine-timing-belt-change-VW-Jetta-TDI-1.htm
