Can anyone help please?

I have a 2004 hse, recently it started making a whistling noise over 2000 rpm, it is also giving off black smoke and the engine management light goes on and off.

Any advise would be welcome.

Thanks
 
deffo with cox325 on this, usually the long one across the front of the engine where the hose chafes on the sound cover fixing screw.

If you replace this hose, cut a bit of the old hose and wrap it round the new one where it chafes to stop the new one doing the same.
 
Thanks for the advise,
Is the hose accessible from under the bonnet or underneath the engine?

If that don't work I made a thing from a baked bean tin some pipe fittings ( I'm a plumber) and put it on the inlet and removed the oil filler cap and pressurised the inlet, makes finding a split in a hose miles easyer, I did this on a golf gti so inlet pipe size might differ,
