An AdBlue fault on a relatively new Crafter

This 2021 Volkswagen Crafter 2.0 TDI CR had covered around 20,000 km when it came in with an AdBlue/SCR system fault. The engine control unit had stored an error related to the AdBlue tank heating element. The video mentions roughly 5,000 km remaining before a possible starting restriction.

The owner chose not to repair the system. AutoChip read the engine control unit software, modified the SCR/AdBlue control strategy and wrote the revised software to the vehicle.

The DPF system and its regeneration function were retained. The video does not show a post-programming diagnostic check or road-test result, so this article records the software work performed and the retained DPF function without claiming further verification.
