VW Group's EA288 and EA897 TDI engines rely heavily on SCR to meet Euro 6. When a NOx sensor drifts out of range, the ECU is quick to start an inducement countdown — even when the hardware is otherwise healthy.

Frequently asked questions
Does AdBlue removal work on a VW Transporter T6.1?＋
Yes. The T6 and T6.1 2.0 TDI are among the most common vans we work on, and the removal is completed mobile through the OBD port.
Will removal affect my Audi's performance?＋
Drivability is unchanged or slightly improved, because the ECU no longer runs SCR-related enrichment and regeneration strategies triggered by faulty sensors.
