Audi AdBlue Delete.
Audi AdBlue Delete enquiries usually centre on TDI models where SCR warnings, NOx sensor faults or repeated countdown messages keep coming back.
What we check
We look at the ECU family, the SCR fault history, dosing behaviour and whether DPF or EGR issues are being mistaken for an AdBlue-only problem.
Before booking
We want the registration, engine details, use case, warning message and any stored codes before deciding whether the vehicle belongs on a delete discussion or a repair discussion.
Use-case review first
Audi vehicles staying in normal public-road service should usually be repaired compliantly. Export, off-road and specialist cases are screened first.
