SOURCE: audi a3 tdi 140 turbo sounds like its whistling
Turbo vehicles often sound like they are whistling when the turbo spools up because it is sucking in air at a high rate and it makes a bit of a whistling sound. Generally not a problem unless it is a different whistling that you are referring to.

SOURCE: replace glow plug on audi a3 2005
If this is a Diesel engine, the glowplugs would be in a position like a sparkplug. You can replace them as you wish, or replace only the bad one. To determine if a glowplug is bad, you would remove it as you do a sparkplug on a gas engine.
With several of the glowplugs removed, you would place a battery jumper cable on one end of the glowplug, while being careful not to damage its threads. That cable would be connected to the NEG battery cable. The remaining cable would be placed on the Positive(+) terminal of the battery and then you would briefly tough the POS cable to the top of the glowplug.
Do this briefly. You can melt the part. But you need to see if the glowplug will glow. Often the problem with glowplugs is the Timer box. This is the box from where the wires come from to go to the glowplugs.
If you have a glowplug staying dark, or failing to glow well, then it is a bad glowplug. Each should glow the same. That is why you check several at a time to tell what is normal.
I work on Ford diesels and do not know what plastic covers you may have. So just follow the wires that are not on the fuel injectors and that is all you can possibly do.
