Symptom-based workshop manual Service 02/21 ENU 4815 4 Symptom on Chassis – Cannot Adjust Electric Steering Column Upwards or Downwards: Observe Specified Procedure (SY 02/21) Model Line: 911 (992) Model Year: As of 2019 Equipment: Safety steering column with electrical axial and tilt angle adjustment (M-no. 2C7) Concerns: Servo motor for electric steering column and front-end electronics control unit (BCM) Symptom: The electric steering column cannot be adjusted up or down. The entry 'B14BF01 – Vertical steering column adjustment, electrical fault (010261)' is stored in the fault memory of the front-end electronics control unit (BCM). Cause: This may be due to particle deposits in the servo motor for the electric steering column. This produces increased resistance by forming a non-conductive oxidation layer. This oxidation is due to the diagnostic current, low processing current and the oiled carbon brushes. Remedial Action: In the event of a customer complaint, the function of the servo motor for the electric steering column must be restored and the front-end electronics control unit (BCM) re-programmed using the campaign code. Information The total time required for control unit programming is approx. 6 minutes. Required tools Information Lithium starter batteries must only be charged using a suitable battery charger that has a current and voltage-controlled charge map. For further information about the battery chargers to be used, see Workshop Manual '270689 Charging battery/vehicle electrical system'. Tools: • • Battery charger with a current rating of at least 90 A and, if required, also with a current and voltage-controlled charge map for lithium starter batteries, e.g. VAS 5908 battery charger, 90A 9900 - PIWIS Tester 3 with PIWIS Tester test software version 40.150.050 (or higher) installed AfterSales Jul 8, 2021 Page 1 of 7 4 Service 4815 ENU Symptom-based workshop manual 02/21 Parts required if necessary Information The parts listed are only required if the steering column needs to be replaced.

Preparatory work WARNING Electrically moved side windows and rear spoiler • Danger of limbs being trapped or severed • Risk of damage to components Do not reach into the danger area. Keep third parties away from the danger area. Do not move components or tools into the danger area. Retract roll-up sun blinds on the rear side windows before starting programming or coding. Jul 8, 2021 Page 2 of 7 AfterSales Symptom-based workshop manual Service 02/21 ENU 4815 4 NOTICE Fault entry in the fault memory and control unit programming aborted due to undervoltage. • Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which can result in one or more fault entries and the abnormal termination of the programming process. Before getting started, connect a suitable battery charger with a current rating of at least 90 A to the jump-start terminals. NOTICE Control unit programming will be aborted if the WiFi connection is unstable. • An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle communication module (VCI). As a result, programming may be aborted. During control unit programming, always connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable. NOTICE Control unit programming will be aborted if the driver's key is not recognized • If the driver's key is not recognized in the vehicle, programming cannot be started or will be interrupted. Place the driver's key with the back facing down in front of the lock opening for the center console cover to guarantee a permanent radio link between the vehicle and driver's key. Work Procedure: 1 2 Connect a battery charger with a current rating of at least 90 A, e.g. battery charger, 90A, to the jump-start terminals in the luggage compartment and switch it on.

Then connect the communication module to the vehicle and switch on the PIWIS Tester. 4 Switch on the ignition. Re-establishing function of servo motor for electric steering column CAUTION Electrically moved components • Danger of limbs being trapped Switch off electric power to drive motor. Make sure it does not switch on again. Check that there is no electric charge. Work Procedure: 1 Establish function of servo motor for electric steering column 1.1 Sit in the vehicle and position the knees under the steering wheel. Electric steering column (shown on Macan) Information The amount of force required should be about 40 kg. 1.2 Press the steering wheel in Electric Electric steering column (shown on Macan) steering column (shown on Macan) -direction of arrow- using a lot of force and at the same time actuate the switch for steering column height adjustment in the corresponding direction of adjustment. Information If this method cannot be used to re-establish function in the electric steering column, it must be replaced before programming. Workshop Manual '481555 Replacing steering column' After replacing the electric steering column, programming must always be performed to prevent any need for subsequent repairs. Programming front-end electronics control unit NOTICE Use of a PIWIS Tester test software version that is older than the prescribed version Jul 8, 2021 Page 4 of 7 AfterSales Service Symptom-based workshop manual 02/21 ENU 4815 • Measure is ineffective Always use the prescribed version or a higher version of the PIWIS Tester test software for control unit programming and coding. 1 4 The basic procedure for programming a control unit is described in the Workshop Manual Workshop Manual '9X00IN Basic instructions and procedure for control unit programming - section on "Programming"'. Specific information on control unit programming in the context of this Technical Information: Required PIWIS Tester test software version: 40.150.050 (or higher) Type of control unit programming: Control unit programming using the 'Campaign' function in the Additional menu on the PIWIS Tester by entering a programming code. Programming code: W5N3E Programming sequence: Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence. During the programming sequence, the front-end electronics control unit is re-programmed and then re-coded automatically. Do not interrupt programming.
