What does the system do?
EGR meters exhaust gas into the intake to reduce combustion temperature peaks and nitrogen oxide formation. High- and low-pressure circuits may include valves, coolers and additional flaps.
Additional options explained
EGR OFF – Exhaust gas recirculation
What exhaust gas recirculation does and how an EGR OFF request differs from repairing the system.

Function, changes and requirements
What does the option mean?
The option concerns the corresponding control and monitoring. It cannot repair a leaking cooler, coolant loss or a seized mechanism.
What do we check on your vehicle?
We distinguish deposits, valve faults, cooler leaks and implausible air-mass signals, and assess the whole emissions system. The exact control unit, software version, fitted hardware and intended use determine the scope. A configurator entry does not replace this assessment.
Frequently asked questions
Does every vehicle support this function?
No. We check the vehicle, control unit and software against the actual supported function. Include existing faults and modifications. Transmission functions also require the exact gearbox version.
Does selecting an option approve its use?
No. Changes to emissions, noise or protection functions can affect legal use and operating safety. This page promises no road approval; diagnosis and a permissible repair are considered first.
