Accelerator clicking

[Gham]

Hi, Looking some information. I bought a 2019 Audi Q5 quattro 2ltr diesel with 54k on the clock. I took it for my first long run and once I hit about 60mph a clicking noise started coming from the accelerator and wouldn't stop it would go from a few clicks to quiet rapid to a point I could feel the clicks on my foot and they became loud. I believe the Q5 has some issues with this and it's linked to the ABS I assume but most forms say nothing to worry about and it goes away after a few minutes I done a 70 mile journey and it was pretty much constant the whole way. I'm struggling to think what this could be there is no vibration of anything some from the wheels it's solely coming from the accelerator pedal. Any help at all would be very much appreciated
