Possible cause:

- B2/6 (Left hot film mass air flow sensor)
- B2/7 (Right hot film mass air flow sensor)
Affected functions:

- Engine diagnosis

-------------------------------------------------

Test 1: Check component B2/6b1 (Intake air temperature sensor).

Test 2: Check component B2/7b1 (Intake air temperature sensor).

Test 3: There are no further test steps at present.

1. Check component B2/6b1 (Intake air temperature sensor).
Important note:Reset quantity mean value adaptation data after replacing the following components:(Control unit adaptations/Reset quantity mean value adaptation data.)

- G3/2 (O2 sensor upstream of KAT)
- B2/6 (Left hot film mass air flow sensor)
- B2/7 (Right hot film mass air flow sensor)
- B4/6 (Rail pressure sensor)
- Air filter
Communication with ECU required

2. Check component B2/7b1 (Intake air temperature sensor).
