S&M Inc Posted May 21, 2012 Posted May 21, 2012 Evening all, I have a 2003 C5 2.0 HDi SX. It started losing power at low revs so I took it to a local garage who did a diagnostics check and advised the air mass sensor was the fault. I've replaced the sensor with no change. Could you please advise if the fault code needs reset? Many thanks Quote
qman3428 Posted May 22, 2012 Posted May 22, 2012 Had the same thing on a C3 changed the MAS and it then showed the EGR was also at fault but the MAS fault was hiding it. You may need a retest to find if there is a second fault. Quote
