E46 M3 noise from front right when turning left

[Mayboy]

Hi

When i turn left at any speed, even if slightly left, i hear a clicking noise from what sounds like the front right hand wheel (drivers side). I only hear it if the window is down so it's not that loud. It's speed related and reminds me of the noise i used to get from a dodgy CV joint on my old 106. It's almost like there's something stuck in the tyre which hits something on each rotation, but there isn't. The brakes look in good condition. I'm confident it's not coming from the rear diff. I haven't noticed any difference when driving. Before i take the wheel off to have a look can anyone suggest what the problem might be? It's a 2003 pre facelift SMG car with 38k miles

Thanks
