Technical Knocking and bad looking crankshaft pulley

[Benscorgie90]

hey all iv just got a knocking noise on my 2014 1.6 doblo at idle as soon as you rev it the knock goes away which I can feel through the peddles. Thought maby it way an auxiliary problem as it goes away if you move the steering wheel. Took a look at the crankshaft pulley and it seems this is pretty busted up?
