Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. In some cases, I may need more information to assist better. I apologize for any delay.
Dear customer, if once the fluid level is verified, the problems with the level still persist, it means that you have problems with the sensor that measures the amount of liquid in the container, it is a very simple sensor, it is good that before replacing we verify that the sensor works with a tester or multimeter, although this sensor is not expensive and can be replaced.
Second, you have a loss of power, this loss of power may be due to lack of maintenance in the injection system or in the air intake system. I do not know if you are carrying out the repairs and reviews on this vehicle yourself, but I would recommend a good injection system maintenance as well as checking the pump, as well as cleaning the injectors as well as the throttle body. I also recommend replacing the fuel filter and the air filter.
My goal is to give you the best advice i can, I hope to be helpful, if you have any doubt or want to know anything else please do not hesitate to reply back.
Kind regards, Sebastian.
