w140 vacuum problem

Hey! I have a problem with my 1994 w140 s-class 350td engine-code: 603.971! I was troubleshooting on the vacuum system bicouse the the turbo loses boost after ca 10 minutes of driving. I was checking the to vacuum valves that controls the wastegate and the EGR (behind the r/s front-light) and now i can’t get the hoses back in there right places. I was wondering if someone could send me some pictures so i can get it back thogeter. I have found some schematics online, but this are in poor quality and its not working at all, when mounted by following this schematics. I will be very greatful if someone with a w140 350td took some pics and posted these And any other leads on the loss of power problem would been a big help.
