I bought a 2019 powerstroke used with 16k miles on it. The day after I bought it the "water in fuel" light came on. In the past 3 weeks I've had it back to the dealership 3 times. The 1st time they changed the filters and the light went out but came back on 4 miles from home, the 2nd time they changed out the sensor itself...this time the light went out but came on the next day. The last time I took it(yesterday) they changed the wiring harness and put another sensor on it....this time it ran like a champ...better than I've ever had it run in the 3 weeks I've owned it but the sensor light came back on 20 minutes down the highway. Has anyone had this issue before and if so how was it fixed. Thanks
