Product Information

This is a DDE SCR / DEF (Adblue), DPF (Diesel particulate filter) and EGR (Exhaust gas recirculation) removal Programming Service for Mercedes GLK250 (X204) BlueTEC 4MATIC Years 2013-2015 with EDC17CP46 ECU.

The SCR - ADBLUE - DEF Tune removes all functions of the SCR / DEF system and removes fault codes in the ECU related to the NOx sensors and DEF and does not require any mechanical modifications to the vehicle.

The Daily Driver Tune has the SCR / DEF, DPF, EGR, and Swirl Flaps deleted. This is a great baseline to start off with to ensure your vehicle is running correctly with the new modifications you have just done. This tune has everything deleted but no performance added, which makes it great for troubleshooting and to compare with the other tunes.

The Daily Driver Tune Plus+ has the SCR / DEF, DPF, EGR, and Swirl Flaps deleted and also has a performance increase. This tune is where performance meets reliability and efficiency. We have created this tune to improve fuel economy while also giving you a very significant increase in power. This tune will transform your car into a high performance machine for your daily commute.

The DUAL Tuning Bundle includes both the SCR-ADBLUE-DEF Tune and the Daily Driver Tune. This combination allows you to quickly resolve NOX codes etc. and then when you're ready tdothe full delete (DPF and EGR), you can write the Daily Driver Tune.

The TRI Tuning Bundle comes with the SCR-ADBLUE-DEF Tune, Daily Driver Tune, and the Daily Driver Tune Plus+

SCR / DEF / Adblue Delete:
This is useful if you want disable the DEF / Adblue system in your vehicle. This will remove NOx codes and other DEF related codes and save you from spending over $8500 for a complete SCR system from the dealer.
Note: If your vehicle has an Adblue Module it will need to be disconnected. Please be advised that any messages on the dash related to the DEF such as "Starts Idle" or "Starts RE5" etc. are stored in the instrument cluster and need to be cleared with a scan tool before the tune can be written to the ECU.

DPF (Diesel particulate filter) Delete:
This is useful when your DPF gets clogged up and starts causing a loss in power or stops regenerating properly. It costs around $3400 to replace, but with our service you can remove it from the exhaust and install a straight pipe in its place or hollow it out.
Note: If the DPF is deleted the EGR also need to be deleted.

EGR (Exhaust Gas Recirculation) Delete:
This is useful if you have EGR related fault codes or if your EGR valve is clogged up and not opening or closing properly. You will need to unplug the electrical connector of the EGR valve, making sure the valve is in the closed position.
Note: If the EGR is deleted the DPF also need to be deleted.

Swirl Flap Delete:
This is useful if the swirl flaps in the intake manifold are stuck in one position which is caused by the flaps getting clogged up with carbon buildup. It is not mandatory to delete the swirl flaps as the tune will allow them to work normally if they are still installed but will also allow you to delete them mechanically and not show any fault codes.
