Hi,

My i30 diesel (2015 crdi) has developed a whistling noise intermittently, it doesn't change with acceleration or deceleration or rpm stationary or moving it's effected slightly by activating the blower in that it changes pitch a little sometimes when I turn the blower on.

It dissapeared for a while when I reseated the air intake filter at least that's what I thought (perhaps I jiggled something else at the same time), but came back and now repeating that process does not have any effect.

Any ideas, it seems like an air leak somewhere but not sure how to track it.

Many thanks,

Ralph.
