Virgin TCU not being accepted

So after a long a drawn out owner struggle trying to encode a virginized TCU conductor plate I deferred to shop. Still not fairing great. They are having issues also.

The tech showed me the screen shot and I think it possibly could be because of a simple mis match of reading and stored info.
One thing I've noticed in the screen shot is; my chassis code isn't on that list of cars needing a valve body.

Also, If you look at the one screen that says if you have sensor error you can go forward with encoding. But the first thing the tech mentioned was they wiped all the error codes before starting the whole encoding process. The tech said there was a category for plate and valve body replacements. So at this point I'm not sure if they can "lie to the system" or hook up my old board and hang it off the car and hope that it pulls the error codes and will effect a correct situation the Diagnostic system will allow further replacement encoding

Thanks Pluto but I have an SDS 4 and the shop has some Autel model. The shops system has the encryption written coding but I don't think my particular situation is in their wheelhouse of descrambling. I need a tech savvy/MB tech with a true background in SDS and code cracking not just a kid an MB dealership reading the prompts on the screen.
Both systems cannot finnish encoding the conductor plate. The SDS I have doesn't have the contract MB leases to encode the encrypted info that stops bad people from stealing and re coding cars. My system has the capability to do offline decoding but something that doesn't show anything besides "ABORT"
has stopped me from finishing the decoding leaving the car dead.

So if anybody out there wants $110 @hr plus a $150 hookup fee and lives in Seattle who can Truly do this I'll also pay a travel fee. It just needs to be encoded

Thanks
Hary

I spent hours going over the the different applications of the DAS files, verification codes. I read multiple different articles on SCN authorization.
Not a big fan of Veidiamo but then again realize its potential if you were that deep but as you too must realize every car & situation is unique
You're correct about not acquiring absolute pinnacle technical no-how in this case but honestly, I have more important things in my life I'm managing. Just looking to finish this and use the car.

Thanks
Hary

Update:

My car was built in Feb/04
Confirmation from Mercedes Regional Service Supervisor that early run model Should be replacing valve body with plate confirming the difference in the plate. I.E. the hard wired Turbine sensor. Not used in regular run NAG2.
Parts are on order. Returning the rebuilt virgin circuit board to be replaced by a blank new factory board.
Like I've said earlier, every car/situation is unique.

When its all wrapped up I'll be very relieved.
