Took car into ford dealership today for a diagnostic to tell me what needed done about the p1381 code. They told me cam needed striping down and gave me a price of £700 with parts and labour ! The thing is the car was running fine for a year even though the engine light was on. When i went to collect the car, started it up, it was spluttering, idling at 2000 rpm and tried to drive off and it stalled 3 times before I even left the dealership car park ! I immediately questioned this and they said the car sounded rough when they took it in when I know it was driving and sounded fine before they messed about with it ! argued the toss with them but they said it was f**ked when i took it in ! Got to go back monday and said im not paying anything until the car is running like it was when i took it in but im guessing its my word against theirs ! What do i do ?
