Bit of a speculative question here but I thought there's no harm in asking...
I've got a 52 plate Focus TDCI which has stood me well since it was a year old. Lately there's been a noticable whistle coming from under the bonnet, like if you blow through gently pursed lips. It seems to build with revs and lags a little begind as you come off the throttle. When it gets to about 2k rpm and the boost come on it's a noticable higher whistle. It's not very loud but is noticable over a quietish stereo.
So, obviously this is some sort of problem with air, intake/exhaust/turbo, but more specifically, what could be the problem and how should I investigate further? I might add that it seems to be running fine.
Thanks in advance for any useful suggestions
