LOL, you are wrong!
The .2 doesn't mean revision, it means that it is a two piston pump. CP4.1 one piston, CP4.2 two piston.
Yes, internet is full of CP4.1 and CP4.2 failures, I think you already know but just choose to think its ok because Ram/Cummins is now using it... unreal!
I have not heard of anyone having any problems with the .2 pumps. I have one in my Ecodiesel and it is in Ford and GM diesels. When Ford came out with the 6.7 PS both Ford and GM had many CP 4.1 pumps fail.
Then Bosch went to the CP 4.2 and no more failures. At least not like we where seeing with the .1 pumps. Are there .2 failures, yes but nothing near what the .1 pumps where failing.
The difference is Ford flat out refused to protect their customers and GM stepped up and warrantied their trucks.
I would not think twice about buying a diesel with the CP 4.2 pump no mater the maker.

They all have catastrophic failures that cost about 10K to repair.
GM quit using them around 2017. They paid out a LOT in warranty claims. For did not pay out so much, as they denied a lot of claims. They still use the CP4.2.
