I think that would suggest that it's vacuum related...
Good luck,

drtony wrote:Thank you all for yor kind advices about the vacuum leak and whistle. It got worse, such that it then became easier to find. Lo and behold it was, as suggested, the inlet manifold, where the W pipe (or, in my case, the inlet box from the turbo) goes into the inlet manifold. Simples (I hope)! I have taken the box off and cleaned the surfaces of several generations of gunk, and obtained two gaskets at an outrageous cost of £1.20. I am awaiting delivery of online ordered black sealant (Sealpro Pro Sealant black), and will reassemble. Slightly concerned about the amount of torque to exert on the four steel bolts going into the cast aluminium. I guess you don't know if you've overtightened til it's too late.
I'll have a go at the interior light as well. Happy days.
