I have no idea unfortunately.
The car has not a lot of mileage, only 70k and has never had any major issue during servicing every year.
That's very unlucky I guess, not sure how long those sensor are suppose to last.

How can I know which one needs to be changed? If I unplug it, can I see it's damaged somehow?
Given I'm no expert as you can tell, maybe I should ask another garage by curiosity.
