Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel level (Bi-fuel)
CNG (Compressed Natural Gas)
The fuel level in the gasoline tank operates in the same way as for vehicles with B5244S6 engines, using a sensor in the gasoline tank. A combined pressure and temperature sensor is used to measure the fuel level in the gas tank. The sensor is on the left-hand side of the gas tank.
The sensor is directly connected to the rear electronic module (REM). The signals from the sensor are transmitted to the rear electronic module (REM) where they are calculated and sent to the driver information module (DIM) and engine control module (ECM) via the controller area network (CAN).
There are diagnostics for the fuel level sensor.
LPG (Liquefied Petroleum Gas)
The fuel level in the gasoline tank operates in the same way as for vehicles with B5244S6 engines, using a sensor in the gasoline tank.
A sensor, on the right-hand side of the tank, is used to measure the fuel level in the LPG tank. The sensor is directly connected to the rear electronic module (REM). The signals from the sensor are compared with a table stored in the rear electronic module (REM). Data about the remaining volume of fuel is transmitted to the driver information module (DIM) and engine control module (ECM) via the controller area network (CAN).
There are diagnostics for the fuel level sensor.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
