[Eskerra]

Hi, good evening to all.
Have a Toyota Yaris 2003, that cluster shows a diferent level on each ignition.
The R711 has been already changed.
I have changed the R15 and R16 as well, but all seems not having success.
What other elemnets please could be involved in fuel level showing??
I read in a post that resoldering the two mcus under the LCD could help, but.....desoldering that lcd is a bit.....

Any other ideas please ???

Thanks so much.
Regards
