Just fitted another brand new pulley from same company.
Does exactly the same. Clunking when you pull away.
Aarrgghhhh
Is it a clatter, or more like a coarse 'chirping' sound (best way I can describe it).
Mine does that if you pull away with too few revs, I have to get the revs and Clutch-slipping 'just-right' to avoid it.
I always thought it was the Dual Mass Flywheel.
