'17 2.0T rough idle at start up?
Hello all,
My '17 2.0T has had a rough idle at start up since I purchased it almost 3 years ago. I had some warranty work done on it before for this reason which involved the dealership replacing one injector which didn't help. My 3 year BTB warranty ends on the 1st, so I took the car in again. The following is what the dealership sent to me in a text update: "Technician scanned the vehicle for codes, there are none stored in the ECM. We checked for bulletins and there's actually a bulletin relating to rough idle on these vehicles. Your vehicle is equipped with high pressure injectors that dual pulse when performing a cold start. This could actually cause a misfire and rough idle, I will attach a copy of this bulletin to your paperwork. Technician is deeming this concern normal operation for make/model of vehicle." Has anyone else with the 2T run into this issue? Any help will be appreciated. Thanks, Sebs_17_2T Last edited by Sebs_17_2T; 03-30-2020 at 11:40 PM. Reason: removing bold on title |

these cars all tend to warm up really rich. people have tried other gas sources. If it were me, I would grab some fuel dryer and see how it goes.
