The Bosch info is for all models. It has E220, I would have E320 a number of different ways. Email me and I'll tell you of a few.

Actually, I just double checked the list and sure enough almost all the codes have doubles or triples. I was looking at impulse codes. If I go to HHT codes the the multiples are expanded to a huge number because at 99 it turns to hexadecimal.
