But when the accelerator is touched the whistle starts and the van will not go over about 30mph any ideas as to what this could be would be greatly appreciated

Sounds like one of the hoses to the intercooler or from the turbo has blown off. Simple problem - you need to make sure the clips are done up very tight and replace them if necessary.

As well as new clips well tightened (7mm socket is best), make sure that all joints are oil free. Otherwise they might well pop off again - even if tight.

Well, back to square one. As Quinny suggested, it sounds like a detached or maybe a split turbo hose. Get someone to rev the engine whilst you have a good listen around the engine bay. And look out for oil leakage / oily deposits around the pipework. Check for soggy hoses. Concentrate on the pipes between the turbo and the inlet manifold, not forgetting the intercooler (if applicable). Pipes to and from the air filter won't be pressurised, so don't worry too much about them.
It could be anything, but checking the pressurised pipework properly really is the first step.
