That bulletin lists the valve cover gasket in addition to the bolts that needed to be replaced as required parts. If bolts were found to be missing or the heads broken off then it stated that the entire Vanos unit should be replaced and the missing bolts/heads had to be found and removed - including oil pan removal if necessary.
Since the 2014 recall covered only a limited segment of vehicles with these engines, it seems likely that the process will be the same for the new recall - presumably this is covering either a wider or the remaining population of vehicles with these engines.

Perfect! Thanks for digging this up - I agree, no reason they would re-invent the wheel here.
