Audi A4 Jaeger 908az60 2j74y problem

[mellon]

Hi.
I have problem with not working temp and fuel pointer. I change mcu for new one 2J74Y but the same. Resolder two resistor and the same. Maybe there is problem with flash mcu or motherboard. Test cluster in vcds works ok but in car pointers not working. I put another cluster and all works OK so original cluster is broken.
Best regards
Adam

But the pointer works in VCDS test instrument cluster! Not working in car but another dash works so I know that problem is on cluster motherboard: mcu 908, broken solder points etc.
