Okay, i'll be as descriptive as I can. I have an Aston Martin that I realized the previous owner pulled fuses on... no idea why, it was not the exhaust, but anyways, this leads me to check my previously owned 911 Convertible as well. Here is what I have "missing" and I don;t know if I need to put the fuses back in. I recently had a service technician look for why my lower signals were not working (cruise and left dash controls) and I think fuses were checked and replaced incorrectly. (not going there again).

2003 Porsche 911 Convt, 6 Speed

A8 is missing - Looks like Canada plates, I think i'm safe there to keep out.
B5 is missing - Noticed my Convt top wouldnt open today, i'm guessing that fixes that.
C5 Shows blank in manual
D9 Audio Option - My stereo is now aftermarket, and was not Bose, so i'm guessing it's okay to be missing.
D10 Telephone - Same as above, no phone = no fuse.
E2 CU MEMORY M537 / M538 - Not sure what this is for, but I have no fuse there...
E5 INFOSYSTEM M662 - Since I have a replaced head unit, I assume it's not needed or could this be for the dash cluster controls?
E10 PSM M476 - No idea why it's missing, but it looks like E9 is also the PSM
