Audi A3 Magneti Marelli shows 999999 km

[didi_du_93000]

Hello,

I have diga consult.
i changed the mileage on a Audi A3 2001 (Magneti Marelli). I used the audi2000 cable.
when i connected the cluster i saw on my TU the good older km (178600km), and after this i programmed the cluster at the new value (120000km) with no problem.
But when i put the cluster on the car i see " 999999" on the dash screen.
when i read the km with the TU, i read the good value (120000km). If i return the old dump (178600km), i saw always "999999" in the dash screen although i saw the old value on the TU (178600km).

what is my solution please

Because with OBD isn't possible.
With OBD the TU read the value but no change.

Have you got a solution please?

Try different value , remove fuse . remove battery . drive a bit .
a3 can be problem sometimes . but will go int the end ,

Thanks for your reply.
the dash function now.
i just remove the dash during 24 hours and after this... 100% work.

Thanks
