As in the title. On a BKP 140ps engine. How is the EGR flow detected? I have an intermittent fault code P0401 'Insufficient Flow' show up and despite checking and cleaning EGR system the error returns. Is there a pressure sensor somewhere that I am missing that may be blocked? If so where is it located.
Cheers.
