So you are admitting that the mechanic did something yes? And he didn’t just make something up for the warranty claim. My only reason for posting my “experience” was to give others who had been to their dealer with the exact same problem and didn’t get a resolution some pointers. But then you get members rubbishing or belittling or know different/more in their answer to said posts.
All I would say to conclude this is if a member posts a problem and another offers suggestions where they have experienced the same problem but have experienced a positive outcome rather than throw doubt, belittle or express a view that they were being “conned” it may be a more sensible option to say nothing.
