The Exhaust Gas Recirculation (EGR) system is designed to reduce emissions in diesel engines. However, it can become problematic, leading to performance issues and costly repairs. This guide explores the benefits and considerations of a Sprinter Egr Delete, specifically for Mercedes Sprinter vans manufactured between 2013 and 06/2018 with 2.1L or 3.0L engines. Note: This does not apply to Sprinter 907 models (2019-present).
Understanding the Sprinter EGR System and Why Delete It
The EGR system routes exhaust gases back into the intake manifold, reducing combustion temperatures and NOx emissions. However, this process can lead to carbon buildup, clogging the EGR valve and intake manifold. This buildup can cause:
- Reduced Performance: Decreased power and fuel economy.
- Fault Codes: Triggering check engine lights and limp mode.
- Component Failure: Requiring expensive repairs or replacement of the EGR valve, DPF, and related sensors.
A Sprinter EGR delete eliminates these issues by removing the EGR system functionality. This is often done in conjunction with a Diesel Particulate Filter (DPF) delete, as the two systems are closely related.
Sprinter EGR Delete: Tuning Options
Several tuning options are available for a Sprinter EGR delete, each offering different levels of performance and functionality:
- SCR/DEF/AdBlue Delete: Disables the AdBlue system, eliminating the need for DEF fluid and resolving NOx-related fault codes. This often requires disconnecting the AdBlue module. Dashboard messages related to DEF might require clearing with a scan tool before applying the tune.
- Daily Driver Tune: Deletes the SCR/DEF, DPF, EGR, and swirl flaps. This provides a clean baseline for a modified vehicle, ensuring proper functionality without performance enhancements. Ideal for troubleshooting and comparison with other tunes.
- Daily Driver Tune Plus+: Offers the same deletions as the Daily Driver Tune but includes a performance boost, improving fuel economy and power output. This tune delivers a noticeable upgrade for daily driving.
- Dual Tuning Bundle: Includes the SCR/DEF/AdBlue Delete and the Daily Driver Tune, allowing for a staged approach to modification. Address NOx codes first, then proceed with the full DPF and EGR delete when ready.
- Tri Tuning Bundle: Includes all three tunes: SCR/DEF/AdBlue Delete, Daily Driver Tune, and Daily Driver Tune Plus+. Provides maximum flexibility and allows for experimenting with different performance levels.
Performing a Sprinter EGR Delete: Mechanical Considerations
A Sprinter EGR delete involves software modifications and potential mechanical changes:
-
EGR Valve: Unplug the electrical connector and ensure the valve is in the closed position. Some may choose to physically remove the valve.
-
DPF: Requires removal and replacement with a straight pipe or hollowing out the existing DPF.

- Swirl Flaps: While not mandatory, deleting the swirl flaps in the intake manifold can prevent future carbon buildup issues. The tune allows for functionality with or without the swirl flaps.
Sprinter EGR Delete: Legal Considerations
Within the USA and Canada, a Sprinter EGR delete is legal only for racing vehicles not operated on public highways. Check local regulations and emissions laws before performing this modification.
