EGR OFF
Professional EGR Removal: More Power Through Cleaner Combustion
We are a professional provider of ECU tuning files, offering specialized services for modifying the EGR system (Exhaust Gas Recirculation). This guide is intended for automotive engineers and mechanics familiar with engine optimization and emissions regulations.
What is EGR Deactivation?
EGR deactivation is a process of disabling or removing a vehicle’s exhaust gas recirculation (EGR) system. This modification is commonly performed to enhance engine performance and prevent issues related to the EGR system.
Benefits of EGR Deactivation:
✔ Improved engine performance
✔ Increased fuel efficiency
✔ Fewer carbon deposits
✔ Reduced maintenance costs
✔ Longer engine lifespan
✔ Better throttle response and more power
Technical Implementation of EGR Deactivation
Our EGR removal is based on advanced ECU reprogramming to deactivate the EGR system without compromising engine performance. The following parameters are adjusted:
- Fuel injection duration
- Ignition timing
- Air-fuel ratio
- Boost pressure control (for turbocharged engines)
- Deletion of DTCs related to the EGR function
Modified ECU maps for EGR deactivation
- EGR control maps
- Function: Controls the EGR valve opening
- Modification: Set control cycle to zero
- EGR flow maps
- Function: Regulates the amount of recirculated exhaust gases
- Modification: Set flow values to zero
- EGR temperature maps
- Function: Monitors the temperature of the recirculated exhaust gases
- Modification: Adjust threshold values to prevent any recirculation
- EGR position maps
- Function: Monitors the EGR valve position
- Modification: Set valve to remain permanently closed
- DTC maps (diagnostic trouble codes)
- Function: Stores error codes related to the EGR function
- Modification: Disable or delete error codes
- EGR adaptation maps
- Function: Manages EGR system adaptations
- Modification: Reset or disable adaptation values
Important Notes on EGR Deactivation
✅ Deactivation is done by setting control maps to zero and deleting all related DTCs.
✅ Alternatively, the high-pressure EGR actuator can be disconnected and the corresponding error codes removed.
✅ The EGR valve must be fully closed before disconnecting the actuator.

FAQ on EGR Removal
What is the function of the EGR system?
The Exhaust Gas Recirculation (EGR) system reduces emissions and helps control combustion temperatures.
Does removing the EGR system affect engine temperature?
Yes, higher combustion temperatures can increase thermal stress, which may affect engine lifespan in the long term.
What effects does EGR removal have on fuel efficiency?
Fuel efficiency can improve, especially under certain load conditions, but in some driving modes, increased fuel consumption may also occur.
What are the legal regulations regarding EGR removal?
The removal of the EGR system is prohibited for public road use in many countries but may be permitted for motorsport or off-road purposes.
How does removing the EGR system affect turbocharger performance?
By eliminating soot and oil deposits in the intake system, the lifespan of the turbocharger can be improved.
Can EGR error messages be disabled?
Yes, disabling the corresponding diagnostic trouble codes (DTCs) prevents the check engine light from illuminating.
What risks does the engine face after EGR deactivation?
Poorly tuned EGR deactivation can lead to excessive heat buildup. Therefore, it should only be performed by experts.
Common error codes (DTCs) related to the EGR system
- P0400 – EGR Flow Malfunction
- P0401 – Insufficient EGR Flow Detected
- P0402 – Excessive EGR Flow Detected
