The sensor itself is about £40, but when asking generally about it at Mercedes, they want about £300 to change it! however ...... earlier in the year when my P60 arrived, I'd noticed that the figure in the red box ie the amount they said I would use if completing a tax return was way less than my total for the year. So I phoned the HMRC to ask if an error might have been made. He looked at various figures & agreed that an error had been made & that their estimate for my tax rebate was wrong.
