I just got a message from the dealer that my black K5 is back waiting for me, and that it's been replaced. Not sure how long it's been, but less than 10 days I think. Nothing to complain about.
Now I guess I have to decide which one to keep - the silver or the black?
and whether to get the 3rd faulty 16-50 replaced or not?
Ho and definitely hum
all the best
