I've got these two codes.
P1435 - multiplexed additive pump. CAN network fault or pump.
P1434 - multiplexed pump, pump fault.
So thought it was the additive pump so took it from the additive tank (mines the bag one) and hooked the pump up to a battery source. The motor works and is pumping the liquid up and through its outlet port. So I stuck it back on the car.
Tried clearing the codes and didn't work. Can this problem cause the car go into limp mode and anyone know what next steps I can take?
