Affected Vehicles
Condition
"Refill AdBlue" message shown in the instrument cluster display despite sufficient AdBlue fluid within the passive and active tanks.
Technical Background
The proper tank adaptation steps are outlined in the ElsaWeb Repair Manual instructions for filling the vehicle with AdBlue. Each time 1.5 gallons (6 liters) or more of AdBlue is added to the system (during PDI or other service procedure), an adaptation must be performed. This condition will only occur if the instructions are not followed properly and the adaptation step is ignored.
An adaptation is required to ensure the sensors inside the active tank can correctly determine the AdBlue fluid level. Without this adaptation, the AdBlue warning indicators may prematurely activate. This will result in a no start condition if the 1,500 mile countdown is ignored.
Production Solution
Not applicable.
Service
1. Take a photo clearly showing the "Refill AdBlue" message and the vehicle mileage in the cluster.
2. Create a Technical Assistance Center ticket. Attach the photo to the ticket.
3. Top off the AdBlue fluid level using the steps outlined in the ElsaWeb Repair Manual. Take note of how much fluid was added to the system and include this information on the TAC ticket.
4. After topping off the AdBlue level, perform the level adaptation step using the VAS 5052 (or similar) scan tool. (This step is included in the ElsaWeb Repair Manual procedure.)
In the tester, under Guided Fault Finding, select Powertrain >> Engine >> OBD >> Engine Electronics J623 >> Engine Electronics functions >> Adapting reducing agent tank adaptation values.
