问:玻璃纸跛行模式再引燃

我买了一个f - 350白金回到2014年9月。我把大约9000英里,检查引擎灯了。然后进入跛行模式。我得到代码p207f并阅读autozone 300英里从我住的地方。那么经销商打电话说他们找不到任何代码。我必须清楚他们回家。然后在我的卡车约14500英里开始可怕,进柔软的模式运行。我是7英里从经销商,决定把。他们做了一个再引燃,删除错误的发动机功率控制模块代码,我拿起了车。我长途驱车3900英里的往返。 The fuel mileage was only 11.3 and went through 4 - 2.5 gallon cans diesel exhaust fluid. I was a driving around town for a week with the fuel mileage down to 10.3. Monday the Check Engine Light came on again. I took it to back to the dealer and they had to replace the Nitrogen Oxide sensor. My truck has less than 24900 miles on it, and it’s been in the shop 3 times already. I've seen the Technical Service Bulletin that Ford put out along with all these stories on the Internet about these 2015 regen – diesel particulate filter issues. Is my truck bad? I do allot of traveling and need reliable transportation. I have about 12,000 miles left on my warranty. Do you have any thoughts or ideas on this truck?
