Hot Film Mass Air Flow Meter, Remove and Install  

  Remove, Disconnect   

Loosen hose clamps (1). Disconnect wiring harness plug (2) from hot film mass air flow meter. Remove hot film mass air flow meter from air intake hose.     Inspect    With external damage (e.g. deformation of grid), replace hot film mass air flow meter.

Notice: 

Before assembling components of the intake system (hoses, connections, etc.), they must be cleaned of any possible contamination (grease, oil, etc.). When tightening the hose clamps, be sure to observe exactly the tightening torque of 3.5 Nm / 2.6 lbf. ft.  

The arrow on the hot film mass air flow meter indicates the direction of flow of the intake air.  

  Important!   

It is only ensured that the intake system is free of leaks, thus ensuring operational safety of the engine, if the hose clamps are tightened correctly to the prescribed tightening torque.  

  Install, Connect   

Insert hot film mass air flow meter into air intake hoses - make sure that hose connections are in perfect condition and correctly seated.   Tighten hose clamps (1) and connect wiring harness plug (2) to hot film mass air flow meter.
