  Summary

  Complaint There may be creaking noises when steering while stationary or driving slowly. See Example Noise attachment Cause The vehicle level of the front axle may be too low. The noises when steering can be caused by continuous contact of the end stop buffer with the damper tube. Remedy The vehicle level must first be measured using the romess inclinometer (follow WIS instructions!) and the measured values should be compared with the target values in the Wheel Alignment online tool. If the vehicle level is out of tolerance, then the springs on the front axle must be replaced in order to correct the level. The currently installed springs can be pulled up in the XENTRY Parts Information tool through the corresponding selection. Verify currently installed spring in vehicle with use of color dots. NOTE: If no dots or color markings, please check the parts label that is affixed to the spring. If the MB part number is listed, continue with process listed in the paragraph below. If the part label does not contain an MB part number, is missing or illegible, please open a TIPS case. In order to find the correct or next highest spring, the spring filter must be removed in the XENTRY Parts Information tool. The spring item numbers are normally listed in sequence (observe and verify valid SA code for vehicle). The next strongest spring is selected by the ascending, next highest item number. IMPORTANT: Do not apply document to vehicles outside of the listed validity range.

  Summary

  Complaint The flap of the reversing camera opens and closes by itself during forward travel. This happens several times during the trip. The customer notices the sound of opening and closing. No camera image is displayed in the head unit. The reversing camera or the 360° system functions normally when activated manually or by engaging drive range "R". This behavior occurs again during each driving cycle. Cause This is not a malfunction, but an intended system behavior: Calibration of the reversing camera is in progress. For this, the cover on the camera is opened for max. 5 cumulative minutes in forward travel. The calibration can be performed if the vehicle speed is < 35 km/h and the steering wheel angle is < 10° (for early vehicles from MFA2 facelift model series such as A-Class, CLA, etc., the 35 km/h (~22 MPH) opening limit may only be reached after the SCN coding is replaced). If the speed of 35 km/h (~22 MPH) is exceeded, the camera retracts and the calibration is therefore aborted. The sequence is started again once the speed returns to the range of 18 km/h (~11 MPH). Remedy Complete the calibration successfully. For this, the vehicle must be driven forwards for a certain time (usually significantly less than one minute) at a speed < 35 km/h (~22 MPH) and a steering wheel angle < 10°. This should occur during daylight and without a vehicle following too closely (the camera must be able to see the asphalt). When calibration is successful, the camera flap closes automatically at an unchanged speed. For the rest of the driving cycle, the camera now only opens if the customer requests this, for example by applying the reverse gear. When starting a new driving cycle (ignition change), another calibration is required. The customer can generally perform calibration at the first attempt when a speed in the range between 15 km/h (~9 MPH) and 35 km/h (~22 MPH) is briefly maintained and can therefore play a significant role in reducing the actuation frequency and therefore also the noticeability of the noise to a minimum. In the case of early MFA2 facelift vehicles (A-Class, CLA, etc.), the parking control unit may have to be SCN-coded again to have the complete speed window available for the calibration.

  Summary

  Complaint Rear lamps fogged up/not leaktight. Cause Fogging of the rear lamps is a natural phenomenon, which can occur under certain climatic conditions. This does not lead to any technical impairment of the rear lamps. Remedy Rear lamp: Remedy 1: Clearing fogged/condensed rear lamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4 °F) Note: Do not wash the vehicle or subject it to high-pressure cleaning before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the trunk. 4. Switch on the exterior lighting. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation -> a significant reduction in the formation of condensation must be clearly recognizable (defogging progress). Note: -If no reduction in the degree of fogging is visible, the rear lamp is defective and must be replaced. -It is not physically possible to defog the headlamps completely – some residual fogging may remain. Fogging does not impair the functionality or the service life of the rear lamps. -Simultaneous fogging of multiple component parts indicates extreme climatic conditions and also does not impair the functionality or the service life of the rear lamps. Remedy 2: You can recognize a defective rear lamp as follows: 1. Check the rear lamps to ensure that no external damage is present, and that the differential aeration cells and the diaphragm are present and correctly seated. -> If there are signs of external damage on the rear lamp, the component parts must be replaced as per WIS instructions. 2. Check the electrical connectors of the plugs and pins. -> If moisture/corrosion/etc. is present, the component part must be replaced as per WIS instructions. 3. Check for leak tightness -> Close all openings with Terostat IX or similar and establish and stabilize via an overpressure (40–50 mbar) via the plug. -> In the event of a sudden pressure drop, the component part must be replaced as per WIS instructions. Note: External damage to the rear lamps does not constitute a warranty or goodwill case.
