LI82.35-N-0789302025-04-03. Service bulletin. VISIBILITY/WIPER. Warning Lamp "Washer Fluid Empty" Yet Reservoir Is Not Empty Complaint: Warning lamp "washer fluid empty", even thought the washer fluid reservoir is full Cause: Insufficient electrical conductivity of the washer fluid, as the washer fluid was mixed with distilled water. Tip: The washer fluid sensor detects the electrical conductivity. If air is present without electrical conductivity between the measuring points, as is the case with an empty tank, an empty tank is detected by the sensor. Distilled water also does not have electrical conductivity, meaning that the sensor detects an empty tank, even if this is not the case. Remedy: Fill reservoir with standard washer fluid and water (no distilled water) in an adequate ratio in order to ensure electrical conductivity. Exchange of the reservoir with a welded-in sensor is only required if filling with conductive washer fluid has not provi- ded a remedy. This can be made certain by utilizing water with a light amount of salt dissolved in to it for stronger con- ductivity.

Complaint The check engine light or AdBlue warning is activated, accompanied by one or more of the following fault codes rela- ted to the AdBlue tank: P206B31: Malfunction of the concentration sensor for AdBlue; the signal is absent. P203B31: Malfunction of the AdBlue fill level sensor; the signal is absent. P300494: The quality of the AdBlue is insufficient. Cause A. The software for the AdBlue (SCR) control unit (N118/5) is outdated. B. The concentration of AdBlue is either above or below the Mercedes-Benz specifications, which can lead to prema- ture freezing. C. Frozen or partially frozen AdBlue can cause the AdBlue level sensor to misread levels. D. The AdBlue level sensor is damaged. Remedy A. Software 1. Verify no newer software in AdBlue® SCR control unit (N118/5). 2. Complete LI49.20-N-075995 for Adblue warning reset. --NOTE-- If there is no updated software available, proceed to step B. B. Adblue Concentration 1. Verify the AdBlue concentration according to WIS AR49.20-D-9264TS - Check the concentration of AdBlue. --NOTE-- If the AdBlue concentration is below 31.8% or above 33.2%, it must be replaced. Please note that this will be at the customer's expense. 2. If the AdBlue concentration is within the approved specifications, please proceed to step C. C. Frozen Adblue or the SCR Actual Values state 'Frozen Adblue' 1. Check if the AdBlue is frozen. If it is, let the vehicle sit in a warm place overnight and recheck. 2. Have the vehicle running and XENTRY hooked up displaying Adblue level values 3. Drain the Adblue Tank and verify fill level reflects the change in the Adblue level 4. Fill the Adblue Tank SLOWLY and do not overfill, verify fill level reflects the change in the Adblue level --NOTE-- The Fill Level Sensor 1 functions as the "empty sensor." It accurately measures the bottom 60 mm (2.3 in- ches) of the AdBlue tank. Once the tank is filled beyond the 60 mm (2.3 inch) mark, the sensor may not read accura- tely, and you might notice the displayed value fluctuating. This behavior is normal, see attachment 'Fill Level 1'. 5. Reset the Adblue Tank fill level via XENTRY --NOTE-- If the XENTRY still shows that there is frozen Adblue or the concentration is still inaccurate after draining and filling, please refer to the attachments 'Adblue Frozen' and 'Adblue Concentration' and proceed to step C. 6.

Fill the Adblue Tank SLOWLY and do not overfill, verify fill level reflects the change in the Adblue level 3. Reset the Adblue Tank fill level via XENTRY 4. Complete LI49.20-N-075995 for Adblue warning reset. --NOTE-- During LI49.20-N-075995 for Adblue warning reset, please ensure that the outside temperature sensor is reading above 10 degrees Fahrenheit. If it is not, keep the vehicle inside the shop overnight. Complete LI49.20- N-075995 again. Additionally, please note that the vehicle may need to be driven to allow the NOx sensors and SCR system to complete their self-test. Once this is finished, the P13DF00 code should be stored and can then be cleared. --NOTE-- During cold weather, when temperatures are below 32 degrees Fahrenheit, please advise the client to keep the AdBlue tank fill level between 50% and 85%. This will allow for proper fluid expansion and help prevent damage to the level/concentration sensor.

VS3RADREI2024-07-04. Service campaign. UNKNOWN OR OTHER. Mercedes-Benz AG, the manufacturer of Mercedes-Benz Vans, has determined that on certain Sprinter and Metris vehicles, the B-pillar certification label might not contain information on the vehicle's rim size, tire size, and cold tire inflation pressure required under FMVSS 110 or, as applicable, FMVSS 120. In this case, relevant regulatory requirements might not be met. Mercedes-Benz believes this issue has no impact on vehicle safety. Mercedes-Benz intends to submit a petition to NHTSA for exemption from the notification and remedy requirements of 49 U.S.C. chapter 301, pursuant to 49 CFR Part 556, on the basis that this non-compliance is inconsequential as it relates to motor vehicle safety. MBUSA will conduct a service campaign to remedy new vehicles in dealer inventory. An authorized Mercedes-Benz dealer will replace the Certification Label on the affected vehicles.
