Hi all, just wanted to document my experience getting the crankshaft on my bmw n47 crankshaft (https://relianceautomotive.co.uk/product/bmw-2-0d-n47-d20-forged-crankshaft/) engine replaced at Reliance Automotive. Like many others, I ran into the dreaded knocking and rough idle that pointed straight to crankshaft wear. I was skeptical at first, but Reliance came recommended, so I gave them a shot. From diagnosis to delivery, here's how the process went — sharing in case it helps others dealing with the same problem.
