Removing/installing

1

Switch off ignition

2

Remove air filter housing (1).

AR09.10-P-1150SX

3

Remove the electrical connector (2) at the hot film mass air flow sensor (B2/5)

4

Disengage the right notch (3a) of the hot film mass air flow sensor (B2/5) at the resonance intake manifold (4)

 In doing so pull right notch (3a) upwards enough so that it cannot latch again on the resonance intake manifold (4).

5

Unlatch left notch (3b) for hot film mass air flow sensor (B2/5) on resonance intake manifold (4) and tip hot film mass air flow sensor (B2/5) somewhat to the rear

 Do not the damage the grid (A) in the process as it cannot be replaced separately!

6

Disengage the spring steel sheet (5) and remove the hot film mass air flow sensor (B2/5) from the air duct housing (6)

 Do not deform the spring steel sheet (5) in the process permanently; it will not get locked properly at the hot film mass air flow sensor (B2/5) during installation.

Checking

7

Check the gasket (7) between the air duct housing (6) and the hot film mass air flow sensor (B2/5) for damage

8

Check right and left notch (3a, 3b) as well as spring steel sheet (5) for damage

9
