The logic of this exclusion egr and very similar to that of MJD6jf. Let's look at the email address you 1DCC12 esa 379E dec 14238. If we multiply the value 14238 x 0,000421 we obtain the value in voltage (about 6 volts) that activates the egr valve.If we bring this high value of when that would never get the battery voltage ,the work is done.In my case resulted in over 17volt.
Place the two files and photos.Good day to all.
