Which C Class models have AdBlue?

The W205 C Class (2014-2021) has AdBlue on higher-output diesel variants from around 2018. The W206 (2021 onwards) has AdBlue fitted to all diesel models as standard. The main affected engines are the OM654 2.0-litre diesel, which covers the C200d, C220d and C300d. The easiest way to check is to look for a blue DEF filler cap near the fuel filler or in the boot. If it is there, the car has AdBlue. W205 models built before mid-2018 may not have the system at all. If you are unsure, call us with your registration and we will confirm your exact production date and engine spec before you book.

What the delete involves

The delete is carried out through the OBD port using specialist software. No parts are removed from the car. The ECU is updated to disable the AdBlue system completely. Once the work is done, all warning lights clear, the countdown timer disappears and the car will not enter lockout. There are no fault codes stored and nothing flags on a standard diagnostic scan. Most Mercedes C Class deletes are completed in 60-90 minutes at your location.
