These systems are pretty sraight forward. Air will work its way out by cycling operation. Did you see leakage from any other cylinders? Continue to cycle back and forth while making sure you keep fluid in reservoir. Go to tophydraulics.com for everything you need to know about it.

Ive got a 01 CLK320 convertible in shop right now working on leaky cylinder issues. It was previously owned by Alex Murdaugh and it is my understanding it was one of Maggies cars.
