LIQUI MOLY Mass Air Flow Sensor Cleaner Liquid Spray MAF 200ml

A special tool for cleaning the sensitive element in the air flow sensor (DFID) in gasoline and diesel engines. Prevents problems caused by incorrect operation of the air flow sensor and the corresponding incorrect composition of the fuel mixture, such as poor engine start, power drop and increased fuel consumption. The tool is often an alternative to costly replacement of DFID.

Aerosol composition based on isopropanol with cleansing components. Removes all typical DFID pollution: soot, oil, dust, etc. It evaporates quickly and does not damage the sensors from any materials: platinum, semiconductor film, etc.

- Special composition for cleaning DFID
- Safe for all types of sensors, including film
- Quickly and effectively removes impurities from the air flow sensor
- evaporates, leaving no residue

Using Luftmassensensor-Reiniger allows you to economically and easily eliminate the problem of incorrect operation of the air flow sensor, without resorting to its expensive replacement.


Remove the electrical connector from DFID and remove the sensor from the engine. Liberally spray the product on the sensor sensor and allow residues of contamination to drain. Do not touch the sensor elements with your hands or tool. Dry the sensor completely before installation. It is recommended to use when scheduled replacement of the air filter or when problems arise in the engine. Caution: Before use, check for compatibility with plastic on the outer parts of the sensor housing.
