I am having trouble removing the Turbo on my 2003 Ducato 2.3 multijet 110 Bhp in releasing what I believe to be a v bland clamp attaching the metal air intake tube to the turbo. I have undone the clamp bolt but nothing has released. The metal intake tube is still fixed tight to the turbo, is there a nack to releasing? The engine is still in situ so access is restricted. Thanks

All sorted from underneath with a good torch managed to lever with a screwdriver around the edge to release the band it was a little corroded that was causing it to be stubborn.
