1

Switch off ignition

2

Remove air filter housing (1).

3

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

4

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

Pull right notch (3a) upwards while doing this until it can no longer latch onto the resonance intake manifold (4).

5

Unlatch left notch (3b) for hot film MAF sensor (B2/5) on the resonance intake manifold (4) and tilt hot film MAF sensor (B2/5) slightly to the rear

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

6

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

Do not deform 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 seal (7) between air duct housing (6) and hot film MAF sensor (B2/5) for damage; replace if necessary

8

Check notches (3a, 3b) and spring steel sheet (5) for damage

If notches (3a, 3b) are damaged, then the entire hot film MAF sensor (B2/5) must be replaced with a new one.

If the spring steel sheet (5) is damaged, then the entire air duct housing (6) must be replaced.

Replace air duct housing.
