had problems with my car a few months ago and the ecu died (water damage)
changed ecu, not long after mil light came on
fault was egr valve insufficient flow
egr was replaced and mil light reset
within a few days light was back on same fault
egr was swapped again incase new one was faulty
light came back on ,reset mil light again
now mil light comes on randomly within around 10 miles of running car good job i have vcds
also changed maf sensor for a new bosch unit ,mil light came back on again
what else can i try ??
was going to login and check adaption values for egr but cant remember security login code .
fed up of driving around with laptop in car just to have to reset that annoying mil light
