DerWhite's 356 Porsche




March 4, 2011 Note:  A recent comprehensive effort has been undertaken to locate all of the 356 Porsche Service Bulletins from the beginning through and covering the 356-C/SC Porsches. This effort to find, digitize and list these service bulletins has been extensive and time consuming on the part of more than six well known 356 Porsche enthusiasts. Service Bulletins that were not previously listed on this website, which have been found through this effort have been added below. As time passes, we will endeavor to complete this listing as much as possible. If you have any of the Service bulletins listed by number in red below, please contact this author at the email address listed below!


The purpose of this website is to provide as complete a listing as possible of the Factory Service Bulletins published by Porsche for the 356 series cars 1950 to 1965. Service Bulletins were published for many reasons. Some cover part changes in mid-production. Others cover problem areas discovered in the field. Some cover special service issues, and some even cover stolen cars. They are a wealth of information that is often not found in the factory workshop manuals or the parts books.

Service Bulletins are numbered sequentially by year such as 1/55 & 18/59 for years through 1959. Sometime around 1960 certain numbers are preceded by a letter, such as F1/61, H15/63, & M21/65. The letters used are M, H, and F which stand for:

M = Motor and Clutch.

H = Gearbox.

F = Chassis, Body, Electrical Installation.

Service Bulletins after about 1959 are also color coded. "M" Bulletins are Blue, "H" Bulletins are Reddish Brown, and "F" Bulletins are Green. Sometime later "W" and "S" Bulletins were used which are on cream colored paper. Early Service Bulletins were also printed on cream colored paper. One big problem with Service Bulletins is that they were printed on really crappy paper and as a result, because of age, the paper is yellowing badly and literally falling apart.

   SB 21/61:  Workshop Manual Type 356 B in French                         SB H6/62:  Differential Carrier

        SB F1/62:   Installation of Pull Switch for Fog Lamps                 SB M3/63:  Upper Oil Cooler Fanhousing

You will note as you go through this list that some of the Service Bulletin Titles are missing. They are colored in red. SB #'s with titles in red were taken from available indexes, however the actual Service Bulletin was missing. If you have any of the missing Service Bulletins, I would greatly appreciate hearing from you. A copy of the Service Bulletin would be greatly appreciated, and the info will be added to this list. The information needed is the Service Bulletin number, date, and subject. Recognition will be given in this website for all contributions. Hopefully this listing can be completed for the use of all.
