Now, don't get all excited, this is the service manual 'on-line' http://www.startekinfo.com 6/26/21 free access to MBUSA online manual no longer available, Teutone.
What it is, is the Steve Nervig index to the 126 service manual (at this point just the gen 2 V8 - but I will get around to the others however the group numbers are generally the same).
You can download the index for your CDs from here.
The aim of this index is to allow YOU to SEARCH the archives using the service group and sub-group number to see if it has been posted before, if not, to ask someone to kindly post up the appropriate pages... as they get posted, I also try to link them here for ease of finding them later.
What you will also see, is that not all service groups are there, this means they are not on the service disk so it is unlikely that anyone has posted them or will be able to...
Hope it is helpful...
