Hello Same problem on 2014 Panamera S Hybrid

 

Found this tech document on internet. 

 

Any one know what to check? I think is not a good solution to change the 3 complete vacuum lines. for only a leak o problem on one specific part. 

 

As the systems detects a vacuum problem it disable the electric mode and turn on the engine to ensure the mechanical vacuum pump to work and that way preserve vacuum for the brake booster.
