I don't know if this code refers to boost being too high or too low than expected. In that case it could be a boost leak or something with the turbo actuators (vac lines?) That can be a possibility, all tho it's very peculiar that
the code changed once i put in a new MAP sensor
Do you remember if it came up during hard driving or normal driving?

It ONLY happens when coasting, if i take a different road with no downhill i can drive much farther without the cel coming on. that's why i think the fault is related to the egr check performed by the map sensor. which would trigger a MAP code but actually be referring to the MAP sensor not detecting changes in air flow when the EGR is activated.
