Diga problem. BIG Problem

**lupu_sandu** · 16th October, 2009, 09:12 PM

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?

the cars that you have adjusted, have they had an aftermarket stereo by any chance????

No. I know the issue.
Diga stop working on Opel cars by itself.

Never came across an Astra VDO cluster that would not change with Diga mate... (But I could be wrong)...

I know mate, but even is a TRW dash Diga show you TRW Version when try to change mileage.
But i talk about my dash, is a VDO.
Diga working just great last weak on him, and now stop working.
I think in mainboard defective, but 2 of them?

i try tomorow test it

**lupu_sandu** · 18th October, 2009, 01:39 PM

I try everything. I change dumps, i change chips from CPU board.

I order a new mainboard (blue version) - 90$ from China.
I hope 3-rd will be a lucky number

problem is your adapter mate obd-k. look if there are some resistors or just cables.
If yor board is defective then you should exchange only 74hc04. This one is responsible for K-Line communication.
If you problem is in CPU board,then exchange the 2 74hc244.
believe me ,should be ok.
I have reversed Diga hardware long time ago. I have several solutions for it.

**lupu_sandu** · 18th October, 2009, 08:47 PM

Cable is OK, i tested.
I have change 74HC5410 below display (near NEC processor). Same shit.
Ideea is after changing mainboard it's OK. I guess that CPU board is ok.
