Cause - Software error in door control unit (N69/X). - Power window motor(s) on front door, left (M10/3) and/or front door, right (M10/4) => On vehicles with CODE 808, 809 or 800. Remedy 1.) Read out hardware version of affected door control unit (N69/X) using quick test (see Figure 1). => For door control units with hardware version equal to/higher than 16/20 (year/week), continue with operation step 2. => For door control units with hardware versions 13/49, 14/23, 14/24 and 14/30, continue with operation step 3. 2.) Replace affected power window motor (M10/X). IMPORTANT NOTE (see also SI document under WIS reference): For vehicles with CODE 808, 809 or 800, the only motors in stock are the new power window motors with modified carbon brushes for the front doors. For this reason, when replacing the power window motor left front door (M10/3) or the front right power window motor, it is also essential to adapt the power window parameters in the corresponding control unit, front door, left (N69/1) or control unit, front door, right (N69/2). When doing so, the following procedure must be followed: a) Replace power window motor(s) on front door, left (M10/3) and/or right (M10/4). b) Carry out commissioning of the door control unit(s) for the front door, left (N69/1) and/or right (N69/2) using Xentry Diagnostics. c) Then perform a function test on the power window system by operating the power window switch in the direction of "AUTOMATIC DOWN" and "AUTOMATIC UP"to fully open and close the side window. Note: Only replace the power window motor if the door control unit hardware version is 16/20! 3.) Perform commissioning of affected door control unit. (Path: Xentry Diagnostics => Control units view => DCU-XX (N69/X) => Adaptations => Commission) Note: Since 09.08.2018, a new SCN coding is available for the current software release! Commissioning ensures that the door control unit receives the current software release and the new SCN coding.
