Transaction No.: 2055883/1
Release date: Sep 5, 2019

Condition
Electronic Parking Brake warning evident within the DIP
The front door/s power latching system sporadically does not work. The door remains in the first latch of the door lock and is not closed by the
power latching system
DTC U112300: Databus error value received Symptom 450560 evident within the ESP control unit (electronic stabilisation program) (J104)
And/or
DTC U112300 symptom code 65759 evident within the Onboard supply control unit 2 (J393)

Technical Background
The micro switch signal of the door lock is not recognised or too briefly
A counter-pressure of the door is required to clearly recognise the signal
Check whether there are other TPIs for the complaint, for example the software of the door control units are up to date
NOTE: Only adjust the required front door striker, you must only adjust both strikers if both sides are affected by the issue

Production Solution
Not applicable

Service
1) Check whether the striker runs into the centre of the rotary latch of the door lock and correct it if necessary - Refer to Rep.Gr 57 - Door striker
- To remove and fit
In addition, adjust the striker as far as possible (at least 0.5 mm) further inwards (Figure 1)

Figure 1
If required adjust the door to the inside so that the front door is flush with the rear door - Refer to Rep.Gr 57. A small gap from front to rear door
is possible and will not normally cause wind noises (Figure 2)

Figure 2
Check the function of the power latching system.
IMPORTANT: If it works correctly, the work can be completed at this point
2) In individual cases it may be necessary to replace the outer door seal of the affected door
Refer to Rep.Gr 57
Then glue the new seal in the area of the door lock about 1 mm further inwards (Figure 3)

Figure 3
The power latching system should permanently work correctly.
