Audi a3 jaeger cluster problem

Hi, I have problem with fuel pointer. I change 908az60 on new one and writes 2 different flash but I have 0 liter all the time. In measuring block is 0 ohm. I change pointer motor but nothing.

I think you need check PCB from blue connector PINS:
5-fuel gauge and 8 - engine temp

resolder resistors and top-bottom side junction, hole way from connector to ECU, after shut start work:captain:

I do it before. 5 is fuel and 7 is ground. Temp pointer is OK. I think there is problem with 912. Line from 5 connector is going to 912 processor but I always change 908 and works. So I have problem. Thx for replay Jarek.

I need good dump for 908 and 912. Please help

I fixed but I don't know how! Changed 908, another dump and pointer motor. Works.

I found, micro crack or cold solder point.
