I got my car back from having the sensor changed today. Drivetrain feels great - shifts are smooth and seamless, and none of the tripping over itself that I was putting up with before. I only drove it from the workshop to home but hopefully it's all good from here on.
I got a response from Fair Trading, and their advice seemed encouraging. I then took one of the free consultations at the law society, but unfortunately the lawyer's assessment is I just don't have a strong case (at least against the parties I want to take aim at). About the best I could do is claim misrepresentation against (or team up with) the previous owner, and then
they claim misrepresentation against Ford. Anything else (like arguing expectations of durability or their failure to rectify when it was detected during warranty) might fail the pub test for fairness, but it isn't backed up by law.
I'm just about out of ideas at this point. About the only other thing I can think of is to post something scathing on social media and see if that stirs any action. Otherwise, move on and spitefully avoid doing any further business with Ford and Ford dealers
