Unfortunately can not write this file back with my KTAG clone ,
its showing that is writing and process complete successfully but when i read again to verify the original file is there.
I tried to write a few times with the same result

I use bdm 100 clone,no problem

Tried also with bdm 100 clone but it shows connection error
did you use adapter for that ?
which software version you have for your BDM 100?

Back to square one, ECU replace same errors there
1200 ,0649, 0641, 0633
when I erased errors they came back in a few seconds
when I check live data in scanner exhaust camshaft sensor for bank one, the value does not change it looks like its frozen,
The other 3 sensors acting in specification
switch sensor position same result.
check wire continuity all OK
remove all camshaft sensors to check timing position all marks in center for both banks
check with scope camshaft exhaust sensors for bank 1 and bank 2 .
Bank 1 its yellow , Bank 2 its green
bank 1 sends signal but when scan it ,scanner does not see any reading from that sensor frozen -20 .

Have you check timing chain?

[koziol]

I already remove all camshaft sensors to check timing position all marks in center for both banks

I have the same problem with 2007 C230 US (M272) and we did all steps as you.
I initially had a problem with both sensors on bank 1 and I tried a few MEs. WIth one of them, one of the sensors was showing readings (not with other MEs). Looks to me some kind of sensitivity problem, possibly wiring.
