This video is on the Vauxhall (Opel) Insignia with the 2.0 litre diesel engine (A20DTH engine code). A common issue is getting a turbo over/under boost, MAF or other sensor issues where the car goes into limp and the engine management light (EML or MIL) comes on. Normally turning the ignition off and back on it will restore for a short time until you generally accelerate hard and it happens again.
The turbo pipes crack and will allow air to escape causing this fault. Typically the crack/damage will be at the back where you won't see it!
Replacing it for the same pipe from ebay:

I'd also recommend getting a 75mm jubilee (hose clamp) for the lower end on the 'u-bend' as the original Vauxhall clamp is almost impossible to remove/refit without damage.
