I called their customer service number and the response was more or less - speak to the dealership.

Any ways - I've been searching the forums for other people with the same issue and the parts they needed replaced.

Mostly it seems like the vacuum pump leaks oil into the brake booster line. If the leak is left long enough the brake booster can also fail.

I see three major parts which may need replacement (I'm not worried about minor seals etc as their cost is minuscule).

General consensus seems to be that the vacuum pump is very simple to replace... But I can't find detailed instructions on the booster line or brake booster.

Also - would there be any other parts in this chain I should look at?
