I am currently re-sealing a VE pump on my non-IC first gen and encountered a strange issue:
I bought a AFC diaphragm from a Bosch dealer. When I got my AFC apart I noticed the diaphragm is different from the one the Bosch dealer gave me. Any ideas why? I don't want to put it in until I am 100% sure it will work the same as the old one as I am trying to keep things as original and stock as possible. I tried google...no luck
The one on the left is the one as found in the pump and the one on the right is the new one provided by the Bosch dealer.
