Your supposedly defective ECU arrived safely today, but it will have to wait quite a while before I can get around to looking at it in detail. It was originally an "A" brain, rebuilt and converted to a "B" brain by Bosch at some point. This is a little surprising because Bosch has not accepted the "A" brains as cores for many years, presumably because there were so many changes that they could not be efficiently rebuilt into the "B"s which superceded them. If you just look into the two types you can see that the "A"s were even constructed differently from all the later units. "A" brains were used in 68 and possibly some 69s, but they had some problems, mainly flooding when trying to start, so almost all of them have been swapped to "B" brains. If anyone out there has a 68-9 with an "A" brain, I recommend that you make this swap. I am guessing that VW had a "silent" recall at some point, probably in 69-70, and exchanged a lot of the "A"s for "B"s, and this must have been when Bosch rebuilt some of the "A"s into "B"s, to support that program. Does anyone KNOW if, and when, VW actually did this? Thanks, and Merry Christmas to everyone out there!
