Hoping one of our knowledgeable members can tell me if this is normal. I've only notice it when the roof is down given its not very loud. But when I turn a corner on full steering lock (usually on exiting my work car park or pulling onto my drive) I can hear a faint whistle. If I'm stationary and on full lock and 'bounce' the steering wheel, a slightly louder whistle is apparent. Is this normal? I'm assuming it's something to do with the hydraulic steering. I've not worked out yet how to gets tune out of it!
