Diga problem. BIG Problem

[melcool]

Hy guys (and girls),
I have Tacho Universal from China ver. 2008 January.
TACHO2008 version when power-up is displayed.
My problem is after some uses (10 or more) i cannot modify
Opel Dash (Astra G for example) to OBD2 anymore.

When modify dash to OBD2 use:
Opel>Astra>VDO Diagnostic or 2001 Diagnostic.
Then input new value (old value is not displayed)
When Diga start to modify show on bottom on screen version of dash.
But for me this will not work anymore.

I have same situation and change motherboard of diga, but this work a few weeks and then stopped.
Now i have same f*ucking annoying thing.
Rest of cars seems to do just fine.
Anyone have one solution for this? Or some advice?

Today I have met the same problem!
In the past ...even Diag / TU not shows the current value... under the new value after pressing OK button...should appear version (TRW or xx203 if VDO) but now nothing even if it's VDO!
Any solution for this problem or I have to buy a new TU for Opel by OBD?!
Many thanks in advance!!!
