If you have an error for an air leak, isolate and find the leak or respective leaks and by crimps to rule out or until gone by zone and including the PCV you already did, right?

Verify all possibility of anything multiplicative!

Did you do defaults of ADP by re-coding and resets as I showed you?

Did you verify the TV is not dirty or with burr/damaged harness being very common too?

I will check possible leak again and check TV with harness.
I did this
Start over and reset DTC's 0x01-02-05 key cycle, then 0x01-07-0000003 recode key cycle and then a TV ADP 0x01-04-060 & 063 then start car & idle 1 minute & let's further do readiness in 0x01-04-200 brake and GAS hit it! Hold it and wait for the count down to destruction.
PCV is new and checked no leak.
Is this collect?
if wrong Could you tell me how to ADP please?

Well sure because if an air leak is present insufficient vacuum will be a result in system to suck vapors or operate the LDP and rely on the intake vacuum.

So my next question is what is the status of the mechanical vacuum pump "if supported" and booster signal or booster for hold & does this car support AUX electric brake booster vacuum pump too?

Are you sure N80 0x01-04-070 or was it the LDP 0x01-04-071 ?

Is anything FOD modified?

Seal would be jumping the gun and less likely for this engine but a propane test would indicate that real fast while watching trims.

FYI: Turbo cars are more likely to leak false air through a rear seal & since they expand from a failed or uncontrolled boost entering the block & to force the seal open and leak.

Does your rear seal leak oil?

here is update.
try use propane gas for check leak at rear main seal,was not change fuel trim number.
but use brake cleaner went to change -20% fuel trim.
I replaced rear mail seal then check leak again with brake cleaner, this point no change fuel trim number.
That say had leak at rear main seal I thought.
set readeness still wont finish secondary air system.....
next I`m thinking bad fuel injectors? because car running lean .or still leaking air?
MB 032 second box shows +10%.

What about fuel pump ,filter, strainer, regulation or fid you measure volume & do you really have an unfound multiplicative air leak?

Is the SAI pipe from combi to CAT clear?
