Audi A5 S Tronic Noise

[Dan1561]

Hi,

I bought an Audi A5 2.0 TDI Quattro S Tronic a few days ago. I've noticed when cruising in 5th gear and putting my foot down, the car drops to 3rd gear but makes a clunking/clicking sound. It happens across other gears too but is mostly always on the downshift when putting my foot down. 

I've had a local specialist drive it today and they don't think it's anything to worry about as it's just the gearbox selecting the next gear in advance and being a bit noisy doing it. 

Has anyone else had anything similar? And is it something to worry about it?

Thanks in advance
