Even I managed to convert my ms41.0 to 41.2 without any issues, nor did I have any prior experience. Only by reading the threads as indicated I was able to do it. You need to turn off some dtcs..

You converted m52b20 ms41 to ms41.2?

What did you do with EVAP? ms41.2 is for US cars only and they have different EVAP to euro - I studied components of both systems and do not see simple solution. I'm getting obviously an error after conversion and returned to ms41.0. Or just should I remove stock evap?

simply turning off the not relevant DTCs in ms41.2 . thats all that needs to be done.. among some other minor things. there is a very good description exaclty what needst to be done to convert to ms41.2 from ms41.0 in the conversion thread here. i followed it and it worked..

I'm rather asking what have you done to evap hardware

nothing because it works fine
