My turbo makes some odd chirruping noises (someone described it as a dolphin chattering) when its spooling up, I've been told its because the vanes are sticking and I need to take the pipes off and fill it with Mr Muscle to loosen them off, how much of a task is this? anyone got a H2? - thanks

There’s 2 ways depending on access etc.
You can take egr pipe off manifold and feed a silicone hose attached to mr muscle can down there and squirt in until it is visible. Leave an hour or so and exercise the vnt arm until it’s free and smooth.

Or take off the exhaust from housing and squirt in there.

Once free and smooth out back together and start up,leave to warm and give it a good thrashing.
