Boia sensor de nível de combustível E46 325i

[brauliozan]

Bom dia pessoal,

gostaria de compartilhar algumas dúvidas sobre a Boia (Boia Sensor De Nivel De Combustivel Bmw).
o indicador do painel fica somente na reserva mesmo enchendo o tanque. Já fiz teste do painel e o indicador esta movimentando normalmente.
Nesta caso, qual das duas boias podem esta com problema?
Como retirar para realizar limpeza e medir o sensor?
qual o melhor procedimento nesse caso?


Consegui isso na net, mas como testar?

TEST 6 - Fuel Level sensor inputs in liters
Sub-Tests:
237415 6.0 = Fuel level averaged
*LH sensor input = 23.7 liters
*RH sensor input = 41.5 liters
​
0652 6.1 = total tank level averaged
65.2 liters
​
0667 1_6.2 = indicated value and tank phase
66.7 liters
* 1 = both sensors are ok
* 2 = one sensor fault
* 3 = implausible input​

já agradeço pelo ajuda!

Obrigado
