Which S Class models have AdBlue?

The W222 S Class (2013 to 2020) gained AdBlue on diesel variants from around 2016 in BlueTEC form. This covers the S350d, S400d and S450d with OM656 engines. The W223 S Class (2020 onwards) has AdBlue across all diesel models. Both long-wheelbase variants share the same diesel drivetrain. The blue DEF filler sits inside the fuel flap on both. If your S Class is a diesel W222 from 2016 or later, or any W223 diesel, it has AdBlue. Not sure? Call us to confirm.

What the delete involves

We connect to the OBD port and update the ECU software directly. No parts are removed from the vehicle. Once the update is complete, the AdBlue system is fully disabled: warning lights go off, the countdown timer disappears and the lockout is gone for good. Your S Class drives as normal. Most S Class deletes are completed in 60 to 90 minutes at your location. We run a free diagnostic scan before we start, so you know exactly what you are dealing with before any work begins.
