Started the car up today and there was a very strange noise coming from the engine so i popped the bonnet and it was coming from charger. I stopped the engine and started it again. I thought it might of got a little dry on the scroll as it was due a ptfe spray, in about 20 miles. I took off the blank and the noise got a little louder. I sprayed a little ptfe in and it was still doing it so i stopped the engine completly. The charger has done about 15k and had all the apex seals replaced about 4k ago. It sounded very central in the charger. possibly a bearing on the way out? Prob due a service?
Here is a video i made so you can see/hear. It 1st starts at 11 seconds.

check your charger belt mate - they dont last a huge deal of time (toothed ones dont anyway)
mine sounds like that when its lost some teeth, so i would take the induction kit off and just have an inspection of the belt while its running / when its not.
I'd go for that as well. If it's a PSD kit check your alternator pulley for play too.
Ok will do, but if i go close to the filter you can hear it coming from inside and it did get louder once i took the blank off.

If there are teeth missing or the belt is real loose it ends the vibrations through the charger - I had a loose belt once that seemed to be vibrating the scroll to the eye. Doubt it was doing the charger any good though!

Justin thankyou very much!
I went out and started taking the induction kit off, then found a little bit of rubber by the earth lead, turned out to be a tooth from the belt. Had about 6-7 missing withing 2-3 inches. New belt on and it runs fine. Thanks mate.

Ah good mate. Always keep a spare belt in the back; they don't last long unforunatly!
