Hi,
To me it sounds like the serpentine belt tensioner which is ‘sticking’ to the belt wilst cold..
Had it on my xk 2007 but after replacing the belt due to a cooling water leak. My independent used an after market belt
After replacing the belt for an original one, the ‘stickin’ of the tensioner was gone….
Don’t know about this engine and his belt tensioner though…
Regards
Pascal
