Lambda reading outside limits on the Volkswagen Polo
Lambda reading outside limits on the Volkswagen Polo is recorded on 25,801 tests — 1.1% of all its MOT tests, against 0.5% across every car in the data. That is 2.2× the national share.
Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 0.5% of tests record it — this model is 2.2× that share |
| The 183 models compared | 43 of 183, highest first |
| The model's own record | 2,279,964 tests · every year of the Polo → |
A share of tests is not a probability for your car: it counts every Volkswagen Polo 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.
