TECHNICAL SERVICE BULLETIN

SUBJECT

Check Control Message Displayed for Variable Damper Control (VDC) 

SITUATION

Check Control message: "Driving comfort restricted, continue driving at a moderate speed, and have it checked by your BMW Center". Check Control ID 180 active for variable damper control (VDC).

CAUSE

The VDC control unit detects that the wheel acceleration sensor is faulty (fault code memory entry: Value implausible).

Possible fault code memory entry:

1. 482943 - Wheel acceleration sensor - front left - sensor 1 - - value - implausible
2. 482947 - Wheel acceleration sensor - front right - sensor 2 - - value - implausible
3. 48294B - Wheel acceleration sensor - rear left - sensor 3 - - value - implausible
4. 48294F - Wheel acceleration sensor - rear right - sensor 4 - - value - implausible

CORRECTION

Perform the vehicle test and read the VDC fault code memory. If any of the VDC relevant fault codes are present, replace the wheel acceleration sensors as follows:

Fault codes are present for the front axle:

1. 482943 - Wheel acceleration sensor - front left - sensor 1 - value - implausible, and/or
2. 482947 - Wheel acceleration sensor - front right - sensor 2 - value - implausible,

Then:

Replace both  wheel acceleration sensors on the front axle  , as per attached "B370214_Interim_RA37 14 605/37 14 606" instructions.

Fault codes are present for the rear axle:

1. 48294B - Wheel acceleration sensor - rear left - sensor 3 - value - implausible, and/or
2. 48294F - Wheel acceleration sensor - rear right - sensor 4 - value - implausible,

Then:

Replace ALL  wheel acceleration sensors on the front and rear axles,  as per attached "B370214_Interim_RA37 14 605/37 14 606" instructions.
