A3 2000reg. problems instaling new clocks

[triakst]

Hello eweryone. this car had faulty clocks but was still starting. ordered new clock-coded in and all was perfect except mileage showing 000000. then i tried vagtacho and after request to change mileage to original 95000 on the clock appeared 999999miles. tried once again and tacho asked to put in "hex line no" from eprom memory or so...I did put 4 digits then again required mileage and after clicking "ok". clock does displays corect mileage but immo light not coming on when ignition cycled on/off and car is not starting.
I think, i did something bad...
Anybody could explain me how to solve tis one , what tolls and procedures are required?Please...
P.s. tried to reprogram key but cluster says-incorect pin code.:hmmmm2:

this dash is new type with checksum verification, once you try to change odometer without checksum calculation it displays 999999km

If dash is new and come with 0km you can change it easily with vag-com without chksum problems, you enter login 13861 on dash and then on channel 09 enter kilometers/10 , ex 123.450 KM you must enter 12345.

You can try to send dump to me to try recover it :idea:
