By installing a downpipe, the engine ECU will detect that the particulate filter system is ‘defective’ and the car will therefore indicate an engine failure in many cases. Your vehicle software should always be adjusted when installing a downpipe. Feel free to contact us for non-binding information or to make an appointment.
