How does atmospheric pressure affect the EGR?
Different levels of o2 at different heights from sea level, EGR is about using exhaust gases in the inlet but if the o2 level isn't high enough it'd be bad.
Ah that does make sense I guess, I know how EGR works but didn't think about there being less oxygen higher up. Would explain why theres one on the OP's car and none over here.
