Sorry to resurrect an old one but by any chance did the EGR solve your problem? I am having the exact same thing and I suspected the EGR so I unplugged it and replace the fuse and it hasn't blown the fuse again while the egr's unplugged so I'm suspecting that's it but I just want to make sure there isn't a possibility of a wiring issue. Curious what your results were with the dealership replacing the EGR valve. I'd take it in except my car is out of warranty so if I can just diagnose it and repair it myself I'm okay with thatUpdate 6/25/2020
After being in the dealer's Service Dept for 12 days the concluded that the EGR (Exhaust Gas Re circulation) valve has failed and that causes the short circuit that blows the fuse. Since that's part of the emission control system the will replace it under warranty, BUT the EGR valve is on back order--they estimate a 30 day delivery time. Since almost all of my mileage, particularly during this "stay at home" time is on battery I took the car back and will continue to use it. They assure me that no damage will be done, even if the gas engine runs (other than a blown fuse). So if any of you experience this problem, have the technician test the EGR valve.
