Product Information

This is a SCR (Adblue), DPF (Diesel particulate filter) and EGR (Exhaust gas recirculation) removal Programming Service for E90 335d models with a M57N2 engine equipped with DDE73 (EDC17CP09).

SCR / DEF / Adblue Delete:

• This Service is useful when your engine gives you a warning that it will stop running in 200 miles, and when you reach warning level 3, no engine start is possible unless you go to the dealer and spend over $8500 for a complete SCR system.

DPF (Diesel particulate filter) Delete:

• This service 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 service 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.
