As no one at jaguar seems to be able to identify maybe someone with mechanical knowledge might know.
My jag has a whine (even when my wife is not in it) between 45 and 40 mph but only when decelerating. Above or below there is no sound. It's not bearings as they have been replaced. Wheels from another jag were put on and the noise disappeared so they assumed it was tyres. New tyres fitted and sound still there. When I accelerate the noise disappears and when I brake there is no noise. Only when the car is decelerating between 45 and 40.

Hi,
Although automatic, it makes no difference the gear selected. Steering makes no difference. Just collected car after service. They said it is tyres but have already replaced them after they suggested it was tyres the first time they checked the car. They then said it was perhaps wrong tyres! Since the the car had the original tyres when I bought it and the whine was present then I think this is not plausible. I suggested the alloys themselves but the "senior technician" said that shouldn't be the case. I find it incredulous that the supposed specialists have no clue as they can only refer to tyres every time.
The whine is only present when decelerating from 45 through 40. If I accelerate between these speeds the noise disappears but if I take my foot off accelerator the noise reappears. The road surface makes no difference. It also makes no difference if wet or dry.

It is front wheel drive. During deceleration if I gently apply brakes the noise disappears. It only occurs through normal deceleration and when I gently accelerate the noise also disappears.
Thanks
