What fails a 2021 Allied
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2021 Allied
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check tyre pressures and valves 5.5% of tests
“tyre pressure monitoring system malfunctioning or obviously inoperative”
Set the pressures to the figures on the door pillar, not the tyre wall, and check the valves do not hiss. A leaking valve is a two-minute fix that fails a test.
-
Check the wipers and washers 4.5% of tests
“wipers does not clear the windscreen effectively”
Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.
-
Check the windscreen 3.1% of tests
“windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
