Unhook the EGR pipe that goes to the intake a check for exhaust flow. 1.6 EGRs are prone to failure, shaft gets stuck.

Hi, can any one of you use vcds and record values of fuel metering valve activation, fuel pressure regilator valve activation and upload clip for ea288 heated to 90 degrees of field work (idle)?
