Lambda reading outside limits on the Volkswagen Beetle

Lambda reading outside limits on the Volkswagen Beetle is recorded on 2,630 tests — 1.6% of all its MOT tests, against 0.5% across every car in the data. That is 3.2× the national share.

Is this unusual for this model?

A share of tests is not a probability for your car: it counts every Volkswagen Beetle tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.

Years with fewer than 0.2% of tests recording the item are left out: a year with two failures in 400 tests is noise, and this table is not here to make noise look like a trend.
