HELP whit airbag 5QF959655AS

[Redzisss]

Hello, There is a VW airbag unit with a processor TC234-32F, which needs to rewrite Pflash and Dflash. After rewriting the Pflash and Dflash whit the VVDI programmer, airbag unit does not respond to diagnostics. Before rewriting, I tried and the block diagnosed itself. I looked at the board block and there are no problems after my soldering. So I want your opinion. Maybe there is some sector that doesn't read and write, Thank you in advance.

Hi i checking airbag unit in the vehicle.

And try checking the module info with the new file written. If the scanner can read the part number or other info from the module, that means the file being written is bad

Buddy if you with the vehicle, try writing the crash file back and clear it with the scanner. It mostly works

Hi
Year of car
Your file that you wrote on the module.
What happens when you write the original file to the module?

Why did you modify the file and what was wrong before.

Without those basic info how will someone be able to help
