can dealerships know if you switched your ecu to a GDE flashed one when you have service done
If your egr has been tuned by GDE and it gets reprogrammed they GDE can not fix it again. As they have been shut down on the ecodiesel by the EPA.I was told this by GDE this am.This is my understanding and not a official statement by them.egr cooler is nation wide recall. for warranty i have to take to dealership when parts are in or i could loose warranty. That is why i wonder if they can see i have a gde tune that could affect my warranty also
